Hi:  I have an h264-based video for which stream analyses by the 
F35-system ffprobe and ffmpeg report initial errors but then give ok 
results, while mythffprobe and mythffmpeg both crash.

I had mistimed my recording, and downloaded a replacement from the BBC 
via get_iplayer, which would normally transcode to mpeg4, but ran out of 
disk space, leaving the raw download instead.  So it isn't a standard 
MythTV format; but playback in the frontend and other players seemed 
generally ok.  I have since used the system ffmpeg to convert it into my 
normal format.

Here are links to two 20 MB dd-clips.

dd bs=1M skip=20 count=20 if=<infile> of=<outfile>

They aren't packet-aligned or exactly equivalent.
