The new patch appears to work, stuff is synchronized, except: - 30 FPS video still seen as 150FPS by VLC - 15 FPS video emits tons of "[vost#0:0/rawvideo @ 000000000269b580] Clipping frame in rate conversion by 0.199989"
As for the corrupt samples, been able to find the original sources:
- the first is good old Descent
- was cut at exactly 2MB
- works in FFmpeg
- the second is Ridge Racer Type 4
- bad/incomplete extract with a tool that added "RIFF....CDXA" header for
whatever reason
- does NOT work in FFmpeg, comprised of 38 audio streams + 2 video streams
(only decodes some audio then aborts)
- but if I extract the relevant section from it, then works in FFmpeg

Hi!
I just tried what you've suggested, using 150 and setting AVPacket->pts using
sector MSF as LBA.
The results are somewhat mixed:
- NTSC video: A/V synchronized but is now seen as 120 FPS by VLC
- PAL video: A/V not synchronized anymore but still seen as 25 FPS by VLC
can you send the patch for this plus links to one sample for both cases ?
id like to take a look
thx
