#285: RTSP h264 video stream always reports corrupted macroblock

--------------------------+---------------------
 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:
