If a different decoder is used for decoding than the one used for probing, the result is considered a change in format. This is handled correctly but gives wrong information and wastes resources. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3783> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Even if we are not remuxing/transcoding from one format to another (e.g. If we are only invoking ffprobe). I'm attaching a proof-of-concept patch that adds a decoding fflag 'nometaconv'. It doesn't change current default behavior or break conversion if remuxing/transcoding from one format to another. I don't know if this is the right approach. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3836> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

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.
