failure to remux h264 from mkv with pts < dts error

Description

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
