It is 704x288 H264 in a container that neither ffmpeg nor MPlayer know about -
the first eight bytes are "00 00 01 c6 4d 50 47 34" (....MPG4). It transcodes
"fine" (but with an unbelievable amount of messages) with -f h264. The result
shows a (white) time-counter on black background.

Could that be ADPCM or ACELP audio? I ask because the installer also contains a
"G726/G729" audio filter.
