Due to improvements in the recording scripts, most of the stuff the sanity
script was checking for is no longer needed (missing/corrupt video files
are handled by the processing scripts). The version of this script in
master has been cleaned up so that the only things it does are:
- Check that the events.xml exists and is properly formatted xml
- Rebuild flv files from red5 .flv.ser/.flv.info files
The script from master is compatible with the 2.0 code, so just use it
as-is.
This fixes a problem where following the recent red5 upgrade in 2.0 branch,
an flv file is never written for webcam streams where no frames were
received, despite there being recording events.
There's some cases where you can get 0-duration recordings due to
recording event placement (e.g. a single recording event is the last
event in the events.xml). Detect these cases, and treat them like
no recording marks in the archive script (it will stop the recording
from being automatically processed).
I've also adjusted the sanity script to detect these cases and error
out. The recording processing scripts cannot handle 0-length recordings,
you have to manually edit the events. I've added a message to the
sanity log about this.
It's no longer used anywhere in the recording processing, and the one
remaining use in the sanity script can be replaced with a (less buggy!)
function from the video EDL code.
