I am trying to convert a RTSP h264 video stream from a "Geovision" IP
camera to any other format but ffmpeg always sees errors in the video
data. The resulting video only shows the first few lines of each frame.
I've captured a few seconds of video (~4MB) to a file using the "openRTSP"
utility. Unfortunately, your ftp server at upload.ffmpeg.org currently
appears to be offline, so it is here:
