Hi Folks,
I am attempting to narrow down an issue that I am having.
I am using openRTSP to record from Axis P3301 IP cameras (H.264/AAC
via RTSP). In general things are working out great. Unfortunately
about 1% of the files (5 to 6 minutes long) seem to have issues
opening (in QuickTime or any other software (VLC, MPlayer and so
on)). Generally the error I get has something to do with a missing or
corrupt atom.
Here is the command I am using:
openRTSP -q -f 30 -w 640 -h 480 -t -Q -b 200000 -y rtsp://10.0.1.1/axis-media/media.amp?videocodec=h264&resolution=640x480&audio=1&duration=0&fps=30&videobitrate=10000&videomaxbitrate=10000&videobitratepriority=framerate&videokeyframeinterval=2&compression=10&color=1&clock=0&date=0&text=0
> recording.mov 2>output.log & echo $!
The QoS reports seem fine. Sometimes the packet loss is high but that
doesn't seem to directly correspond to corrupt files. (One thing that
is strange to me is that that the packet loss is sometimes high even
though since I am using the -t for TCP which I would expect to be more
reliable although slower than UDP. If I use the -l flag things get
really strange and I seem to double or even triple the bitrate and get
very strange looking video with flashes and so forth.)
I am stopping the recording by issuing a kill -1 PID.
I am glad to dig through the source and try to identify and correct
the issue, I am just not sure where to begin. Any thoughts would be
appreciated.
Thanks!

ps. Should I provide a sample file?
