Comment (by uscgraphics):

 I got the same problem using Axis P1311/P5534-E/Q1755 latest v5.2 firmware

 ffplay rtsp://xxx.xxx.xxx.xxx/axis-media/media.amp

 will see lots of errors (see below), the display image is partially
 corrupt.
 This happens even in the same sub-net without UDP blocking. But if I use

 ffplay rtsp://xxx.xxx.xxx.xxx/axis-media/media.amp?http
 ffplay rtsp://xxx.xxx.xxx.xxx/axis-media/media.amp?tcp

 it works fine.

 Worst of all, my program will crash at
 av_close_input_file(ic);
 whenever the error occurs. Try to catch the crash with _set_se_translator
 fail either.

 If you need login to reproduce the bug please send me email.
