[FFmpeg-user] ffmpeg script to deal with RTSP (UNCLASSIFIED)

[Wunder, Greg P CTR (US)]

Classification: UNCLASSIFIED
Caveats: NONE

My infrastructure is setup such that I am running on a CentOS 6.x 64bit image with FFMPEG 0.10.2.

I am attempting to deal with 2 problems:

1) Time-out and restart of RTSP video source
2) Errors in RTSP video source

My script is as follows: ffmpeg -i "rtsp://192.168.12.3/myFeed" -f flv -an "rtmp://192.168.12.33/live/myFeed"

For #1, every thirty minutes the feed get reset as the video is written off to disk which I have no control over.
How can I have the script wait during this period and then pick-up the feed again rather than manually restart the script?

For #2 I get the following stdout/stderr at runtime causing the feed to have issues (accessing the original RTSP feed with VLC it looks good, but RTMP from the FFMPEG script it does not).
RTMP is hosted via Adobe Media Server 5.0.1.
