Lol, I told you I was struggling with emClient, it decided to send .eml as 
.url...

Here are the patches, hopefully!

Subject Re[2]: [FFmpeg-devel] [PATCH 1/4] avcodec/mdec: DC reading for STRv1 is 
like STRv2

Modern email clients like to do stuff they're told not to...

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

New videos, samples, logs:

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
