Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

Description: +--------------- + +This PlugIn is a VDR implementation of the VTP (Video Transfer Protocol) +Version 0.0.3 (see file PROTOCOL) and a basic HTTP Streaming Protocol. + +It consists of a server and a client part, but both parts are compiled together +with the PlugIn source, but appear as separate PlugIns to VDR. + +The client part acts as a full Input Device, so it can be used in conjunction +with a DXR3-Card, XINE, SoftDevice or others to act as a working VDR +installation without any DVB-Hardware including EPG-Handling. + +The server part acts as a Receiver-Device and works transparently in the +background within your running VDR. It can serve multiple clients and it can +distribute multiple input streams (i.e. from multiple DVB-cards) to multiple +clients using the native VTP protocol (for VDR-clients), or using the HTTP +protocol supporting clients such as XINE, MPlayer and so on. With XMMS or +WinAMP, you can also listen to radio channels over a HTTP connection. + +It is possible to attach as many clients as the bus and network can handle, as +long as there is a device which can receive a specific channel. Multiple +channels homed on the same transponder (which is determined by it's frequency) +can be broadcasted with a single device. + +Additional clients can be programmed using the Protocol Instructions inside +the PROTOCOL file. + + +2. Installation: +---------------- + +Let's say streamdev's version is 0.3.1 and vdr's version is 1.X.X. If you +use anything else please exchange the version numbers appropriately (this +way I don't have to update this section all the times;) ). + +After compiling the PlugIn as stated below, start either (or both) parts of it +by specifying "-P streamdev-client" and/or "-P streamdev-server" on the VDR +command line. + +What's important is that the client requests a channel using its Unique Channel +ID. So, in order to find the channel at the server, it must have the same ID +that is used on the client. You can achieve this by putting the server's +channels.conf on the client, preferably after scanning (in case you use 1.2.X +with AutoPID or 1.3.X). + +If you want to drive additional Input-Devices (with different sources) on the +client, you can merge the channels.conf files. VDR will detect if the local +device or the network device can receive the channels. + +Last, but not least you have to put the provided streamdevhosts.conf.example +into the "plugins" subfolder of your config-directory (which is equal to your +video-directory if not specified otherwise), rename it to streamdevhosts.conf +and adjust it to your needs. The syntax is the same as for svdrphosts.conf, so +please consult VDR's documentation on how to fill that file, if you can't do +it on-the-fly. For example, if you didn't specify a separate config-directory, +and specified your video directory as "/video0", the file has to be put to +/video0/plugins/streamdevhosts.conf. + + +2.1 VDR 1.2.X: +-------------- + +It is recommended that you apply a patch to VDR that improves thread +cancellation. You can work without it, but you _might_ have delays in switching +(especially when using VDR-to-VDR streaming) that are around three seconds. + +cd vdr-1.X.X/PLUGINS/src +tar xvfz vdr-streamdev-0.3.1.tgz +ln -s streamdev-0.3.1 streamdev +cd ../.. +patch -p1 " on your remote. If you want to enter "192.168.1.12", type +"192168112". + +The parameters "Remote IP" and "Remote Port" in the client's setup specify the +address of the remote VDR-to-VDR server to connect to. Activate the client by +setting "Start Client" to yes. It is disabled by default, because it wouldn't +make much sense to start the client without specifying a server anyway. The +client is activated after you push the OK button, so there's no need to restart +VDR. Deactivation on-the-fly is not possible, so in order to deactivate the +client, you will have to restart VDR. All other settings can be changed without +restarting VDR. + +The client will try to connect to the server (in case it isn't yet) whenever +a remote channel is requested. Just activate the client and switch to a +channel that's not available by local devices. If anything goes wrong with the +connection between the two, you will see it in the logfile instantly. If you +now switch the client to a channel which isn't covered by it's own local +devices, it will ask the server for it. If the server can (currently) receive +that channel, the client will show it until you switch again, or until the +server needs that card (if no other is free) for a recording on a different +transponder. + +You can choose a remote streamtype in the setup. I'd suggest TS streaming as +it has a much shorter delay than PES streaming (compared to live-view of the +same channel on the server), and transmits more information such as AC3 and +teletext data. + +When setting the parameter "MultiPID streaming" to yes (the default) (only +applies if the streamtype is TS), only the needed PIDs are transferred, and +additional PIDs can be turned on during an active transfer. This makes it +possible to switch languages, receive additional channels (for recording on +the client) and use plugins that use receivers themselves (like osdteletext). + +The last parameter, "Synchronize EPG", will have the client synchronize it's +program table with the server every now and then, but not regularly. This +happens when starting the client, and everytime VDR does its housekeeping +tasks. The only thing that's guaranteed is, that there will be a minimum +interval of ten seconds between each EPG synchronization. + +The client has a Main Menu entry called "Streaming Control". This is used to +control various aspects of the remote server VDR. Inside, you will find +"Remote Timers", "Remote Recordings", "Suspend server" and "Synchronize EPG". + +The "Remote Timers" entry gives you the possibility to edit, create and delete +the server's timers remotely. Every timer is synchronized before the requested +action actually takes place. This only leaves a very short time-span (of a few +milliseconds) in which a race-condition could happen. + +"Remote Recordings" shows up all recordings that the server can access. Only +deleting recordings is implemented, yet. + +With "Suspend Server", you can send the server into suspend mode remotely, if +the server is set to "Offer suspend mode" and allows the client to suspend. + +Last but not least, "Synchronize EPG" starts a synchronization in case you +don't want to do it regularly, or in case you just activated it and can't wait +for the first synchronization to happen by itself. + +3.4 General Usage Notes: +------------------------ + +If there's still some debug output on stdout, please ignore it ;) + + +4. VDR-to-VDR client notes: +--------------------------- + +4.1 EPG data: +-------------- + +[ OUTDATED, see "Synchronize EPG" in 3.2 ] + +4.2 Teletext / OSD Teletext: +----------------------------- + +Usual teletext will probably not work on the client, if it has no DVB hardware. +I never tried, and probably I never will, so don't ask about it please ;) + +Osdteletext-0.3.1 (and later) definitely work when used in MultiPID Streaming +mode. + + +4.3 AnalogTV +------------ + +Works with ivtv and analogue cards according to Andreas Kool. + + +5. Known Problems: +------------------ + +- Recordings & Timers on the client side could endanger Timers & Recordings on + the server, as they will have the same priority (by default). Set the + default priority to i.e. 40 if you want the server to supersede the client. + +- Sometimes, if you reload VDR too often (for example while recompiling), the + driver can get "stuck" in some situations. Try a driver restart if anything + you think should work doesn't before sending a bug-report :-). + [ ADDITION ] + In the meantime I have discovered that this error is caused by the all- + mysterical UPT (unknown picture type) error :-(. + diff --git a/client/assembler.c b/client/assembler.c new file mode 100644 index 0000000..9e36204 --- /dev/null +++ b/client/assembler.c @@ -0,0 +1,125 @@ +/* + * $Id: assembler.c,v 1.1 2004/12/30 22:44:04 lordjaxom Exp $ + */ + +#include "client/assembler.h" +#include "common.h" + +#include "tools/socket.h" +#include "tools/select.h" + +#include +#include +#include + +#include + +cStreamdevAssembler::cStreamdevAssembler(cTBSocket *Socket) +#if VDRVERSNUM >= 10300 + :cThread("Streamdev: UDP-TS Assembler") +#endif +{ + m_Socket = Socket;
