[Ffmpeg-devel] Some FLV files no longer work in new ffmpeg

[st cnx]

I have 2 builds of ffmpeg. They are both able to decode many flv
files. However the newer one borks on files from porkolt such as

http://www.porkolt.com/other/plane/landing/wheel/cnn/sideways-wheel-landing-3331.html

The old one (a binary I found somewhere on the web) does decode it
correctly when I use the command line:

oldffmpeg -i x.flv -f mov -b 500 -maxrate 800 -vcodec mpeg4 -qmin 3
-qmax 5 -s 320x240 -bufsize 10000 -acodec aac -ab 128 -g 250 -v
-output x.mov



The new one complains about "Output file does not contain any stream"
I believe that's actually saying "Input file does not contain any
stream" because:

oldffmpeg -i x.flv

Seems that stream 1 comes from film source: 1000.00 (1000/1) -> 24.00 (24/1)
Input #0, flv, from 'x.flv':
  Duration: 00:01:06.4, bitrate: N/A
  Stream #0.0: Audio: mp3, 44100 Hz, mono
  Stream #0.1, 24.00 fps(r): Video: flv, yuv420p, 418x234




The new one comes from svn (Feb 13)

What files would cause this? flvdec? Where should I start digging? Or
can someone else who has a clue help figure it out?

Thanks,
