Change subject: New requeueTranscodes.php maint script for TMH
......................................................................
New requeueTranscodes.php maint script for TMH
Maint script to clear old transcodes and batch-queue the new ones.
Supplements/replaces old resetTranscodes.php and retryTranscodes.php...
Can be used to batch-queue all files of a given format/resolution key,
or all resolutions for a given filename, or just those that were
errored out or stalled.
Uses the image table as a source of files to list, so can reach *all*
video files, even those that have not been properly recorded in the
transcode table, and can reach transcodes that have not been listed.
Limitations:
* potentially slow when dealing with all files!
* very verbose output
Todo:
* support audio transcodes
* add a queue-state throttle option for major bulk updates
Examples:
```
mwscript \
extensions/TimedMediaHandler/maintenance/requeueTranscodes.php \
--key=1080p.ogv
mwscript \
extensions/TimedMediaHandler/maintenance/requeueTranscodes.php \
--key=1080p.ogv \
--error
mwscript \
extensions/TimedMediaHandler/maintenance/requeueTranscodes.php \
--file=Folgers.ogv
mwscript \
extensions/TimedMediaHandler/maintenance/requeueTranscodes.php \
--stalled
```
