[FFmpeg-devel] [RFC/PATCH] Pass PRIVATE_STREAM_2 MPEG-PS packets to caller

[Richard]

Hi,

In order to improve DVD playback, I need the DVD NAV packets in-sync 
with the other audio/video/subtitle packets.  The information is stored 
in 'PRIVATE_STREAM_2' MPEG-PS packets (startcode 0x1bf), which are 
currently filtered out.

The attached patch adds a new codec ID 'AV_CODEC_ID_PRIVATE_STREAM_2' to 
identify these packets.

The contents of these packets is clear for DVDs but looking at the 
existing code, it appears that Dreamcast videos (Sofdec) also use this 
startcode but for other purposes, so I'm not sure it's feasible to 
create any sort of decoder for these packets.  As it is, the patch 
simply returns the contents of the packet unchanged.  It is up to the 
calling application to process the contents.

All comments welcome.

Richard.
