2254	Unsupported h264 file	cehoyos		"(videolan ticket 8145)
A vlc user uploaded a DVB recording from TTV HD (Taiwan) explaining that when this broadcast station went on-air, set-top-box provider had to update their firmware to support decoding.
FFmpeg only decodes the first frame, WMP plays the stream recognizable but with heavy motion artefacts.
