- Fixed a possible race condition in generating the DVB device names (thanks to
Rainer Zocholl for reporting this one).
- Changed the way PES packets are played to allow replay of AC3 sound over the
full featured DVB cards (partially based on a patch from Werner Fink).
+ The new function cDevice::PlayPes() is now called with the complete PES data
stream and calls PlayVideo() and PlayAudio() as necessary.
+ cDevice::PlayVideo() is now only called with actual video PES packets.
+ cDevice::PlayAudio() is now called with the actual audio PES packets, which
can be either "normal" audio or AC3 data. You need at least firmware version
0x261d to replay AC3 sound over a full featured DVB card. This function now
has an 'int' return value.
+ PlayAudio() of derived cDevice classes shall no longer call the base class
function. It shall just play the given data as audio.
+ cPlayer::PlayVideo() and cPlayer::PlayAudio() are now obsolete and have been
replaced with cPlayer::PlayPes().
+ All StripAudioPackets() functions are now obsolete. The functionality has been
moved into cDevice::PlayPes(), where only the video and audio packets that are
actually required will be processed.
+ All audio track handling is now done by cDevice; cTransfer and cDvbPlayer no
longer care about audio tracks. cPlayer, however, still has the virtual hooks
for audio track handling in order to allow plugins to implement players that
have their own idea about this.
+ cChannel::[AD]pid[12]() have been replaced with cChannel::[AD]pid(int i) to
allow access to all available PIDs.
