Revision as of 10:37, 1 February 2011


Author Cowbutt
Description A simple bash script based on Silence-detect.sh that wraps mythcommflag and can be used manually (via 'Begin Advert Detection' menu option in recording browser) to use silence detection for commflagging for certain UK TV channels.
Supports Version24.png  


Rename the existing mythcommflag binary

Mythbackend runs the commflag differently according to the configured name (i.e JobQueueCommFlagCommand in the settings table). If it's not 'mythcommflag', then it always runs the configured commflagger with no parameters (i.e. in "flag all uncommflagged recordings"). Therefore it's necessary for this script to replace and wrap mythcommflag. e.g. 

mv /usr/bin/mythcommflag /usr/bin/mythcommflag.orig

Install wrapper script in place of mythcommflag

Install this script as /usr/bin/mythcommflag (or wherever your original mythcommflag binary was located)

Edit script variables

Edit the environment variables in the wrapper script according to your local installation.

Note that you can specify multiple storage directories by separating them with a space. e.g.: RECORDINGSROOT="/media/disk/mythtv/recordings /mnt/nas/mythtv/recordings"

Enable commflagging

Check that commflagging is allowed in mythtv-setup (i.e. the JobAllowCommFlag setting should be 1) and that the commflag command (i.e. JobQueueCommFlagCommand) is mythcommflag.

Test

In the 'Watch Recordings' browser, select a recording that was from a channel included in the script's whitelist (Film4, Dave, Dave ja vu, ITV1-4, ITV1 +1, ITV2 +1), hit menu, then Jobs, then 'Begin Advert Detection'). Within a few minutes, that recording should be commflagged appropriately.

Improvements

Fill in the TODOs.

Expand the channel whitelist ("Five" tested once and failed, others???)

Experiment with other mp3splt options for other channels

Merge this into the real mythcommflag. Will probably need a new column in the channels table to signify which commflagging method should be used, and that in turn will require some work to the channel-editor UI of mythtv-setup.
