  • Added --answer feature for passing in answers to title and description questions
  • Various enhancements. See ticket changeset 10047 for details.

mythcommflag

  • Added --getskiplist to print out the commercial skip list, useful for making .edl files for mplayer

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
  • Adds a new option to mythfilldatabase called --no-new-channels which ignores new channels in the lineup. This actually removes the new channels from your lineup, as if you had gone to the zap2it website and removed them manually.
  • Renamed --do_channel_updates to --do-channel-updates for consistency with the other options.
  • Fixed xmltvid insertion in manual mythfilldatabase channel insertion mode
  • Avoid automatic update of DataDirect lineup when there are no new channels for us to remove from the listings
  • Log the wget stats, probably the most important info in the mythfilldatabase output

mythjobqueue

mythreplex

  • Added compilation as standalone executable. Needed by MythArchive

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
  • Fixed a couple mythtranscode related bugs that show up when you have multiple backends running jobs for each other and they have different recording directories
  • Add recording profile setting to allow specifying filters to apply when performing lossy transcoding with mythtranscode

mythwelcome

  • Skip redundant events properly
