VDR Plugin 'streamdev' Revision History
---------------------------------------
 
- Report the server-side HTTP status "503 Service unavailable" instead of
  the client-side error "409 Conflict" when a channel is unavailable
  (suggested by Methodus)
- Update of po headers and Finnish translation (thanks to Rolf Ahrenberg)
- support for non-cycle-free setups (e.g. where two VDRs mutually share
  their DVB cards through streamdev-client/-server). Must be enabled in
  streamdev-server setup. Obsoletes recursion patches.
- API change of VDR 1.7.22
- VDR 1.7.22 obsoletes cap_net_raw patch. Added cap_net_raw patch for VDR
  1.7.5 - 1.7.21.
- Update and UTF-8 conversion of Finnish po files (thanks to Rolf Ahrenberg)
- Added "Hide mainmenu entry" option on server (thanks to Rolf Ahrenberg)
- Added server menu with list of clients. Connections can be terminated
  with the "red" key. The former main menu action of suspending live TV
  moved to the "blue" key.
- code cleanup and optimization (thanks to Ville Skytt<74>)
- properly shutdown IGMP timeout handler thread when the plugin is stopped.
  Fixes occasional segfaults on VDR exit.
- fixed memory leak in libdvbmpeg read_pes (thanks to Ville Skytt<74>)
- dropped several unused functions in libdvbmpeg
- restricted VTP command RENR to liemikuutio patch < 1.32. Build fails with
  newer versions of this patch (thanks to Ville Skytt<74>)
- updated outdated COPYING file and FSF address (thanks to Ville Skytt<74>)
- include SDT and TDT in TS streams
- the icy-name HTTP header sent with radio streams makes VLC pick the wrong
  demuxer. Send icy-name only for ES audio streams.
- fixed regression of "live TV must be switched in VDR main thread" change:
  deadlock in IGMP streaming server when switching live TV.
- streamdev-client returns true in its AvoidRecording() method introduced
  with VDR 1.7.19. Note however that the impact of NumProvidedSystems is
  higher.
- updated device selection to code of VDR 1.7.19
- adaption to VDR 1.7.12 cReceiver API change
- increased WRITERBUFSIZE. Has been reported to fix some ringbuffer
  overflows (thanks to Lubo<62> Dole<6C>el)
- check availability of channel if VTP command TUNE is called without
  prior PROV call (e.g. client side EPG scan)
- added support for VDR 1.7.19 SignalStrength/SignalQuality
- analog video channels use the same transponder and pid for different
  channels, so streamdev-client must always issue TUNE command
- server must close the VTP connection also if filter stream is broken
- fixed missing #ifdefs for new NumProvidedSystems setup option
- new externremux.sh mencoder config options: audio pid by language code
  (-alang) and verbosity (-msglevel) (thanks to Pekko Tiitto)
- writer must not spend too much time waiting in select() without checking
  if the thread has been cancelled
- added Spanish translation (thanks to Javier Bradineras)
- live TV must be switched in VDR main thread
- dropped compatibility with VDR < 1.5.16
- return value of streamdev-clients cDevice::NumProvidedSystems() now
  configurable in plugin setup

2011-02-11: Version 0.5.1

- updated copy of GetClippedNumProvidedSystems to the version used since
  VDR 1.7.15 (reported by carel@vdrportal)
- fixed the code deciding if a device is in use for live TV or not. It did
  not work as expected for FF cards (reported by wtor@vdrportal)
- increased client side timeout for TUNE command
- more dsyslog messages to help troubleshouting channel switch issues
- improved the channel switch code trying to move live TV to different card
- make sure that a client doesn't interrupt replaying on server's FF card
  (reported by wtor@vdrportal)
- switching away live TV failed even when "always suspended" (reported by
  Michal Novotny)
- fixed regression: no receiver created for ES/PS/PES (reported by Gavin
  Hamill)
- VTP no longer uses a static priority value for its server-side receivers.
  The server stores channel and priority requested with the PROV command and
  re-uses these values in a subsequent TUNE for the same channel. The new
  PRIO command is used to update the receiver's priority if necessary.
- added parameter HEIGHT to externremux.sh
- fixed syslog messages reporting local instead of remote IP and port
- fixed regression of the GetDevice(...) change. Filter streaming to clients
  with a recent VDR version no longer worked.
- log an error if externremux.sh is missing or not executable
- since VDR 1.5.0 cDevice::GetDevice(...) is no longer a query only method.
  It detaches all receivers of the device it returns. So it is no longer
  suitable for testing the availability of a device. Added a copy of VDR's
  cDevice::GetDevice(...) without the detach receivers part as a workaround
  until a better solution is available
- added dsyslog messages to help troubleshouting channel switch issues
- VTP command SUSP didn't attach the player to the primary device
- fixed incompatibilities with older make versions
- replacing a connections receiver is now an atomic operation. Solves
  stuttering audio/video due to lost TS packets when adding/removing PIDs
- disabled attribute warn_unused_result in libdvbmpeg
- slightly increased thread priorities of cStreamdevWriter/Streamer
  (suggested by Rolf Ahrenberg)
- fixed missing support for invisible channel groups (groups without name)
  in HTTP menu (reported by Timothy D. Lenz)
- don't quote actual program call in externremux.sh, so you can run the
  program through e.g. nice or taskset just by extending the variable
  which holds the program name
- in externremux.sh each mencoder audio and video codec has a dedicated
  variable for a default option string now. Still you can override each
  default option with an URL parameter
- externremux.sh mencoder now uses scale parameter with negative height
  instead of -xy for scaling (suggested by vel_tins@vdrportal)
- added FPS (frames per second) parameter to externremux.sh (suggested by
  vel_tins@vdrportal)
- don't use std::map.at(). It's not available in older libstdc++ version
  (reported by Matthias Prill)
- fixed extremux x264 using value of ABR for VBR (thanks to vel_tins@vdrportal)

2010-07-20: Version 0.5.0b

- fixed wrong URL path in m3u playlists (reported by Norman Thiel)

2010-07-20: Version 0.5.0a

- set externremux.sh executable in distribution archive
- externremux quality value should be wlan54, not wlan45 (reported by
  wolfi.m@vdrportal)

2010-07-19: Version 0.5.0

- using SIGINT in externremux to kill mencoder works better than SIGTERM;
  especially x264 still needs a SIGKILL sometimes
- added --remove-destination to cp commands installing plugins
- fixed "plugin doesn't honor APIVERSION" (reported by carel@vdrportal)
- updated Italian translation (thanks to Diego Pierotto)
- config option "client may suspend" hidden if not applicable
- updated and enhanced README
- separated language resources of client and server

- changed HTTP URL path for externremux from EXTERN to EXT (suggested by
  Rolf Ahrenberg)
- HTTP headers now have to be emitted by externremux script
- pass channel related information and URL parameters to externremux script
  through environment
- implement CGI like interface for externremux script
- dropped "Synchronize EPG" feature. Please use epgsync-plugin instead
  (available from http://vdr.schmirler.de)

  (thanks to Udo Richter)
- added compatibility with VDR 1.6 tsplay-0.1 patch
- added support for EnhancedAC3 (thanks to Eric Valette)
- fixed a memory leak in cStreamdevPatFilter::GetPid (thanks to lhanisch)
- length -1 is the correct value for streams in M3U playlists

- now there's a common baseclass for all remuxers, make use of it
- added cDevice::NumProvidedSystems() which was introduced in VDR 1.7.0

- removed cStreamdevStreamer::m_Running
- eliminated potential busy waits in remuxers
- updated cTSRemux static helpers to code of their VDR 1.6.0 counterparts
- re-enabled PES vor VDR 1.7.3+. Streamdev now uses a copy of VDR 1.6.0's
  cRemux for TS to PES remuxing.
- make sure that only complete TS packets are written to ringbuffers
- use signaling instead of sleeps when writing to ringbuffers
- optimized cStreamdevPatFilter PAT packet initialization
