dvb-t encapulated in nuv no audio decoding

[awaldram]

Im in the UK trying to stream using mythstream from a artec DVB-t card in debian.

The stream is mpeg-ps with mpeg audio 2 ch 256 48000

VLC states the following------

the tabs show 2 tracks for audio but nothing plays...

Xine show a 2 ch stereo 256kbit 480000 stream and plays it correctly!!!


I suspect its the parsing of the audio stream from DVB-t cards is busted at least when encapsulated in .nuv

as from this mythtv forum thread..

http://sourceforge.net/forum/forum.php? ... _id=435048

The hauppauge pvrx50 streams fine from.nuv

has anyone succesfully played/streamed dvb-t data from mythtv recording ???

xine reports the file as

System Layer Mpeg-pes
video mpeg 720X576 ratio 17778
audio mpeg layer 2 2 channels bitrate 256000 bits 16 samplerate 48000

Which looks pretty correct to me

heres a quick fix for people with dvb cards

In myth-setup under your dvb card there is an option for advanced recording options.

In this windows is an option to record the raw TS stream rather than encode to PS select this and restart mythtv-backend

so VLC can stream the raw TS but not the PS encoded version though xine has no issues with either.

Should I raise this as a VLC bug??

This fix doesn't work for pcHDTV HD3000 cards.

I have some feedback for the pcHDTV HD3000.

1) PS recordings have great video, but no audio
2) TS recordings have garbled video, and no audio

Any other ideas?
