Unfortunately Lossless Cut gets no indication frommkvmerge that it did
not append the last segment so it automatically cleans up the temporary
workpath directory. There is awayfor you to easily recreate the
individual segment files.
Run Lossless Cut from the command line on the recording with the issue
but add the "-k" option:
> ./lossless_cut -f "/path to/recorded.mpg" -m "/path to save to" -k
The -k will prevent the log file from being deleted. Now open the log
file up with a text editor, unless you changed the workpath, it willlook
something like "/tmp/2575_20121101110000.log"
In the log file is every command line that was executed to do a Lossless
Cut including the one that made all the segments before they were
merged. You can copy that line and then paste it into a terminal session
then hit enter.After it is done you will have all the segment files.
Search for "mkvmerge perform cuts command". e.g.:
2012-10-12 14:43:21,335 - INFO - mkvmerge perform cuts command:
> mkvmerge -o "/tmp/lossless_cut/1081_20121012003000-%04d.mkv" --split
In this same log there is the merge command, search for "mkvmerge create
final mkv video file command".
FYI: The same HDHomerun user who experienced this issue also has another
channel specific issue(ABC), where Lossless Cut creates audio only
cutswith no video track. During my investigation it was noticedthat
these recordings could be compressed in an archive (bz2) over 50%
smaller than the original file. Normally you do not get anywhere close
tothat kind of compression with an mpg file. It was the only thing that
stood out with these files otherwise they played fine even after
extraction from the archive. This is still an outstanding issuewhich is
mentioned on the wiki's Known Limitations section.
Good luck and I hope you spot something. I am very interested in
including the HDHomerun as a fully supported recording device.
