Utility Applications

myth.rebuilddatabase.pl

  • Fixed script for new file name convention
  • Added --answer feature for passing in answers to title and description questions

mythcommflag

  • Added --getskiplist to print out the commercial skip list, useful for making .edl files for mplayer
  • Improved speed during near real-time commercial detection

mythfilldatabase

  • Don't bail out of mythfilldatabase when we fail to retrieve some data. This causes issues for people who have multiple sources and an error occurs with one source. The scheduler would not get triggered and other data fixups would not occur because mythfilldatabase would exit if we had any errors at all.

  • Added a new param to mythfilldatabase "--only-update-channels". This is used now where we only need to get channels, and do not need any listings data

mythjobqueue

  • Parse the -O/--override-setting option

mythlcdserver

  • Fixed LCD crash
  • Updated to support lcdproc 0.5

mythshutdown

  • mythshutdown will now only reboot when the 'nvram-wakeup Restart Command' has been set. If you don't

want or require a reboot after setting the next wake up time in the bios leave this setting blank.

mythtranscode

  • Added --dvd command-line option for inserting DVD NAV packets into stream
  • Improved verbose output by printing cutlist on a single line for MPEG-2 to MPEG-4 transcoding
  • Allow the -s/--starttime command line option to take the date in either YYYYMMDDHHMMSS or YYYY-MM-DDTHH:MM:SS format.
  • Take cutlist into account when computing percent complete during MPEG-2 to MPEG-4 transcoding
  • Fixed to work on systems without soundcard.h

Fix problem reported by Thomas Boerkel with mpeg2<->mpeg2 transcoding. The problem was that if a cutpoint ends on one of the 1st B frames in a sequence header, then mythtranscode would not place a sequence header at the cutpoint, causing an invalid stream.

  • Parse the -O/--override-setting option

mythwelcome

  • Skip redundant events properly
