Hello,
I've done some searches in this forum and in the web and found out that there are other people having this problem.

I think this is a FFMPEG bug, but as it is used in ZM I feel free to ask here.
I'm running Ubuntu Server 14.04 x86_64 w/ ZoneMinder 1.27.99 from ppa:iconnor/zoneminder-master
Currently modetect 2 cameras (System load is always low).
The camera that gives bugs is configured as:
Source Type: FFMPEG
Source Path: rtsp://192.168.1.10:554/user=user&password=&channel=1&stream=1.sdp
Remote Method: RTP/RTSP/HTTP
WidthxHeight: 800x600
There is any bugfix or workaround for this problem?
