Description

Since commit

http://git.videolan.org/?p=ffmpeg.git;a=commit;h=dafaef2fe1e1af7c40adc1855547fd4cba9862a9

ffplay thinks the sample rate is 0 and hence does not play the audio. This issue only affects ffmpeg, not libav. Outut of a slightly modified version of ffplay to dump the channels number and sample rate if any of these are invalid:

  • Resolution set to duplicate
  • Status changed from new to closed

(Third) Duplicate of ticket #213 - I know this probably was originally another issue, but it was the first sample for which I discovered the problem.
(And so far, for all samples, it also failed for me with the fork, I informed the author of the patch before anybody else had reported the problem. If you have a sample that works with the fork, but fails with FFmpeg, please share.)

This should be fixed in latest git HEAD, please test.

Yes, indeed. Thanks.
