[MPlayer-users] demux_pva fixes

[Matteo Giani]

All,

I noticed current svn was not working correctly on quite a few of the PVA format samples, in particular it would not decode audio correctly.

After looking into it, I realised the demuxer did not set the "needs_parsing" flags inside the audio and video sh structures, which in particular for audio caused the mentioned breakage.
I guess this flag was a later addition to the rest of the demux code, which demux_pva was not adapted to comply with.

Patch attached does 3 things:

* adds setting of needs_parsing flags
* fixes behaviour in case a PES audio header in the source file did not contain PTS field
* some cleanup / simplification (e.g. removing unused / useless #ifdef blocks which were originally there for testing back in the day, etc)

n.b. I am the original author of the demuxer, just recently found a couple of hours to look at what had become of it. Was unsure whether to post this directly to -dev-eng ; I will be happy to repost there if people feel it is appropriate.

Best regards,

Matteo
