 This problematic mkv used in the command line belwos was recorded by
 TVheadend off Satellite on a UK HD (BBC) channel.

 The 5MB sample can be downloaded here:
 http://bubblesoftapps.com/tmp/ToyStory2.2014-04-13.20-00-sample.mkv

 The command line attempt to keep the h264 stream (copy) and convert the
 mp2 audio track to mp3.

 It fails with a pts < dts error, generating a very short 100Kb file.

 If the h264 is transcoded to h264 instead of just copied, it works.

 So there seems to be a problem keeping the original video track while
 transcoding the audio track.

 How to reproduce:
 {{{
 % $ ffmpeg -y  -i ToyStory2.2014-04-13.20-00-sample.mkv -map 0:0 -c:0 copy
 -map 0:1 -c:1 libmp3lame -ac:1 2 -b:1 320k test.mkv

 Yes, it's the issue with the file. QDM2 audio in files generated by
 mkvtoolnix-6.6.0 are broken (this bug was fixed in mkvtoolnix-6.7.0). You
 don't have to fix FFMPEG for them.

 You failed to provide any relevant information.

 Please do not edit keywords, if your issue is not a regression, open a new
 ticket instead of reopening this one (that was a regression).

 Is it reproducible with {{{-an}}}? If yes, please use it to simplify the
 command.
 Is it reproducible with an internal encoder like {{{-vcodec mpeg4}}}? If
 yes, please use it, it makes reproducing issues significantly easier.

Comment:

 But it didn't work for me. It would be great if the underlying problem can
 be fixed in this case. Posting logs in case it helps.

 Here is the command I executed:
 ffmpeg -i .Files/1szqpq/hjmuqD/creation/overlaid-video.mp4 -itsoffset
 22.952 -i
 .Files/1szqpq/hjmuqD/creation/07eda82db409f6c212ffa829287d9c0d_clip.webm
