Relates to ticket 7595, which has just been closed. I use this script to
preprocess mpeg2 recordings from dvb-t. Applying the cutlist via
Project-X within MythArchive sometimes gives the wrong sound channel and
means that the size of the final file is not known when the recordings are
selected. This script tells the user what PIDs are present and requires
him/her to specify two: one video, one audio. The cutlist is not applied
with single-frame accuracy but I have found it robust and 'good enough'.
I have had very few failures when the script has been used on the original
recording; it seemed less reliable when used on recordings that had been
preprocessed using mencoder.
The script (still called mythcutprojectx) uses ideas from scripts found in
the mythtv lists: mythcutprojectx and pxcut.sh
I also use a version of mythburn.py that I have hacked to use
M2VRequantiser instead of the deprecated tcrequant and to create a dvd
image with all video mean bitrates subject to a common upper limit. This
version was not created under svn and includes changes addressing a number
of issues. It has been used only under a narrow range of circumstances. I
would like guidance on how to submit it. Regrettably the version of
M2VRequantiser that I use seems to be no longer on the web.
