#1348 closed defect (duplicate)

Can't hear sound with vlc after transcoding from pcm u-law to aac

Description

I have transcoded H263/ulaw video (input.mp4) to H264/aac (output.mp4) using this command line:

ffmpeg -i input.mp4 -acodec libfaac -ar 48000 -vcodec libx264 output.mp4

see (ffmpeg_trace.txt)

=> In VLC, input.mp4 plays well with sound but not output.mp4 (no sound).

  • Component changed from FFmpeg to avformat
  • Keywords mov mulaw added; ffmpeg pcm ulaw aac removed
  • Resolution set to duplicate
  • Status changed from new to closed

Looks like a duplicate of ticket #522, please reopen if this is still reproducible with current git head.

I thought the change created 8 weeks ago by reimar was included in 10.3. Am I wrong?
