See the file COPYING for more information. Requirements: DVB compatible MPEG1/2 or H.264 network video streams. Description: This plugin integrates multicast IPTV transport streams seamlessly into VDR. You can use any IPTV channel like any other normal DVB channel for live viewing, recording, etc. The plugin also features full section filtering capabilities which allow for example EIT information to be extracted from the incoming stream. Currently the IPTV plugin has direct support for both multicast UDP/RTP and unicast HTTP MPEG1/2 transport streams. Also a file input method is supported, but a file delay must be selected individually to prevent VDR's transfer buffer over/underflow. Therefore the file input should be considered as a testing feature only. IPTV plugin also features a support for external streaming applications. With proper helper applications and configuration IPTV plugin is able to display not only MPEG1/2 transport streams but also other formats like MP3 radio streams, mms video streams and so on. Installation: cd /put/your/path/here/VDR/PLUGINS/src tar -xzf /put/your/path/here/vdr-iptv-X.Y.Z.tgz ln -s iptv-X.Y.Z iptv cd /put/your/path/here/VDR cp -R PLUGINS/src/iptv/iptv /path/to/vdrconf/plugins/ make make plugins ./vdr -P iptv Setup menu: - TS buffer size [MB] = 2 Defines ringbuffer size for transport stream in MB. Valid range: 1...4 - TS buffer prefill ratio [%] = 0 Defines prefill ratio for transport stream ringbuffer before data is transferred to VDR. Valid range: 0...40 - EXT protocol base port = 4321 Defines base port used in EXT protocol. The port range is defined by the number of IPTV devices (max. 8). Valid range: 0...65527 - Use section filtering = 1 Defines whether section filtering shall be used. Valid range: 0...1 - Disable filters = 0 Certain section filters might cause some unwanted behaviour to VDR such as time being falsely synchronized etc. This option allows creation of blacklists of ill-behaving filters. If this option is set to a non-zero value, the menu page will contain that many "Disable filter" options which allow you to disable the individual section filters. Valid range: 0...7 - [Blue:Info] Opens IPTV information/statistics menu. Information menu: - [Red:General] Opens the general information page. - [Green:Pids] Opens the pid statistics page. - [Yellow:Filters] Opens the section filter statistics page. - [Blue:Bits/bytes] Toggles between bits and bytes mode. Configuration: - channels.conf TV4;IPTV:40:S=1|P=0|F=EXT|U=iptvstream.sh|A=0:I:0:0:680:0:0:4:0:0:0 TV3;IPTV:30:S=0|P=1|F=FILE|U=/video/stream.ts|A=5:I:0:514:670:2321:0:3:0:0:0 TV2;IPTV:20:S=0|P=1|F=HTTP|U=127.0.0.1/TS/2|A=3000:I:0:513:660:2321:0:2:0:0:0 TV1;IPTV:10:S=1|P=0|F=UDP|U=127.0.0.1|A=1234:I:0:512:650:2321:0:1:0:0:0 ^ ^ ^ ^ ^ ^ ^ | | | | | | Source type ("I") | | | | | Stream parameter (multicast port | | | | | number, HTTP port number, file delay | | | | | (ms), script parameter) | | | | Stream address (multicast address, URL, file | | | | location, script location) | | | Stream protocol ("UDP", "HTTP", "FILE", "EXT") | | Pid scanner ("0" disable, "1" enable) | Section id (Sid/Nid/Tid) scanner ("0" disable, "1" enable) Unique enumeration - UDP multicast rules for iptables firewall # Multicast UDP -packets iptables -A INPUT -i eth0 -p udp -d 224.0.0.0/4 --dport 1234 -j ACCEPT # IGMP required by multicasts iptables -A INPUT -i eth0 -p igmp -d 224.0.0.0/4 -j ACCEPT External streaming: - To watch an externally received channel add an EXT entry to channels.conf and specify a script name and parameter. The specified script is executed from plugin configuration directory when VDR tunes to the channel. The specified script parameter is passed to the script and it can be used to select for example between different URLs. - When an EXT channel is opened the IPTV plugin opens an UDP listening port on the localhost. The external script is responsible for supplying IPTV plugin with MPEG2 TS data in UDP/RTP format to the listening port. The data will be processed in VDR like a normal DVB broadcast. The listening base port can be specified in the plugin configuration menu. - Each IPTV device has different listen port. The port number is specified as a base port number plus IPTV device index minus one. Maximum of 8 IPTV devices can be used simultaneously. - IPTV plugin includes an example script which uses VLC media player for receiving streams, transcoding and handing the result to IPTV plugin. Notes: - Working EIT requires correct Nid/Tid/Sid values as the NIT filter cannot determine the type (satellite/cable/terrestrial) of the IPTV transport stream. - The following section filters are recommended to be disabled: "NIT (0x40)", "SDT (0x42)", "TDT (0x70)" - The IPTV devices look for a "/tmp/vdr-iptv.dvr" fifo at startup. If the fifo is found and succesfully opened, the device writes the current data stream into it. This can be used for debugging purposes. - Multiple channels with identical service id should have frequency difference of 4 or greater. It's recommended to use frequencies in decades (10, 20, 30, 40, ...) for all IPTV channel entries. - VLC processes won't get killed on some setups with the provided iptvstream.sh script and the iptvstream-notrap.sh script should be used instead in these cases.
