Thanks for the idea.

That concatenates the files, not the video streams, though 
ffmpeg/ffprobe seems to recognise it regardless.

Unfortunately, ffprobe still shows the frames out of order on this 
concatenated file, though both frames have PTS=0. Doing a `ffmpeg -i 
'001+002.mkv' -c copy joined.mkv` doesn't change this.
