Comment (by andrewc):

 I believe I've hit a related (if not identical) bug with "Geovision GV-
 FE420" (which almost caused me to lose my sanity). When viewing an rtsp
 stream (in zoneminder) via ffmpeg, the output is corrupted in almost every
 frame after the first. VLC displays ok, but disconnects after 20-40
 minutes. I currently have a ticket open with Geovision, so far they have
 been responsive but we haven't gotten very far into resolving this issue.

 openRTSP dumped the RTSP stream ok, where as ffmpeg (head compile 5 days
 ago) generated a lot of errors to stderr/stdout.

 I will perform the test recommended by cehoyos, and post the results
 tomorrow. Alternatively, if you believe this to be unrelated, I will open
 another ticket.
