Mythcommflag is the internal process used by the backend to flag commercials in MythTV recordings. There are various options that can be set on how commercials are detected. See the front end configuration manual for details.

Usage

$ mythcommflag --help
Misc. Options:
--chanid                    Specify chanid of recording to operate on.
--dry-run                   Don't actually queue operation, just list what would
                            be done
-O OR --override-setting    Override a single setting defined by a key=value
                            pair.
--override-settings-file    Define a file of key=value pairs to be loaded for
                            setting overrides.
--queue                     Insert flagging job into the JobQueue, rather than
                            running flagging in the foreground.
-h OR --help OR --usage     Display this help printout, or give detailed
                            information of selected option.
--version                   Display version information.
--starttime                 Specify start time of recording to operate on.

Commflagging Options:
--method                    Commercial flagging method[s] to employ:
                            off, blank, scene, blankscene, logo, all, d2,
                            d2_logo, d2_blank, d2_scene, d2_all

--method does not currently accept text values. See http://code.mythtv.org/trac/ticket/10793 and http://code.mythtv.org/trac/ticket/10989

Instead use integers: 0=off, 1=blank, 2=scene, 4=logo

Combine methods by adding: ie blankscene=3=1+2, all=7=1+2+4

Add 256 for the experimental d2 methods eg d2_logo=260=256+4. One developer commented that the d2 methods are slower, but no better.

Note that when --method accepts text values, d2_all does not include the d2_scene method - found to be unhelpful, especially in the US. So d2_all=261, and not 263

The experimental methods appear to have a current fault. An infinite loop, causing a failure to process the job queue and using 100% CPU. See http://code.mythtv.org/trac/ticket/11141

--outputmethod              Format of output written to outputfile, essentials,
                            full.

--outputmethod option is currently ignored and defaults to essentials. See http://code.mythtv.org/trac/ticket/10793 and http://code.mythtv.org/trac/ticket/10989

--rebuild                   Do not flag commercials, just rebuild the seektable.

Advanced Options:
--force                     Force operation, even if program appears to be in
                            use.
--outputfile                File to write commercial flagging output [debug].

Input Options:
-f OR --file                Specify file to operate on.
--video                     Rebuild the seek table for a video (non-recording)
                            file.

Logging Options:
--loglevel                  Set the logging level.  All log messages at lower
                            levels will be discarded.
                            In descending order: emerg, alert, crit, err,
                            warning, notice, info, debug
                            defaults to info
--logpath                   Writes logging messages to a file in the directory
                            logpath with filenames in the format:
                            applicationName.date.pid.log.
                            This is typically used in combination with --daemon,
                            and if used in combination with --pidfile, this can
                            be used with log rotators, using the HUP call to
                            inform MythTV to reload the file
--nodblog                   Disable database logging.
--noprogress                Don't print progress on stdout.
-q OR --quiet               Don't log to the console (-q).  Don't log anywhere
                            (-q -q)
--syslog                    Set the syslog logging facility.
                            Set to "none" to disable, defaults to none.
-v OR --verbose             Specify log filtering. Use '-v help' for level info.

Choosing a Recording

Two methods are available to choose which recording to work on. The first is to specify the channelid and start time,

--chanid 1067 --starttime 20060424183000

Note the start time format is in YYYYMMDDHHMMSS.

The other method is to specify the file,

-f /MythTV/tv/1856_20060425200000.mpg

Rebuild Seektable

Many times the seektable may be bad, or you may do some editing of a recording outside of Myth. In order for Myth to properly FF, RW and seek it needs to have an up to date seektable. If this issue occurrs, you can use mythcommflag as one of the possible tools to repair the seektable.

Important.png Note: After rebuilding the seektable, any cutlist you have will no longer be properly synced and should be recreated.

Non Flagging Operations

The following options are mutually exclusive with commercial flagging, and if specified they will cause mythcommflag to perform an action other than commercial flagging.

--video filename             Rebuild the seektable for a video (non-recording) file
--rebuild                    Do not flag commercials, just rebuild seektable

Examples of Mythcommflag Jobs Speed

Script

Run this script to add entries to the examples.

#!/bin/bash
#
# Script to generate wiki formatted mythcommflag report.
#
# Usage:
# 1. Download and save this script to "mythcommflag.report.sh" 
# 2. Run mythcommflag -f mythtv_recording_of_your_choice.mpg
#  - After logo detection the fps for commercial flagging will be printed out.
#    Change FPS below to your FPS that is reported (eg FPS="50 fps") and save this script.
# 3. Run "sh mythcommflag.report.sh mythtv_recording_of_your_choice.mpg"
#  - Cut and paste output and add to this website (you must first create an account to edit this page).
#
