RECONTUPD

Name

recontupd

Purpose (one Line Only)

Update start and ending times for RECON event video files in the database

Description

The recon.data database is queried for all event videos (catid='E')
whose utdate is known and utstart or utend is still set to NULL.
Broken video files are skipped.
For those videos scanned, the beginning and end of the video is extracted
to determine the start and stop time of the video. The location of the
video end is expected to be consistent with the video duration posted
in the database. If the file ends early that file will be marked
broken in the database and utend will be left as NULL.

Inputs

Optional Input Parameters

Keyword Input Parameters

DT - integer number of seconds to skip into the file to read the starting
time code. The default is 0 which will lead to decoding the second
video frame. This should be used sparingly and usually when there
is a single stubborn frame remaining to be processed. If used,
the starting time is estimated from the frame read, pushed backward
by the offset, DT, used.
IDX - If provided, turns on a special mode and just a single database
entry is scanned. In this mode, the usually email report is
disabled.
MAXTODO - mostly for testing, if set will restrict this program to process
no more than MAXXTODO records.

Outputs
