Description
This seems to be known and is referred to in the help text, but I didn't see a ticket for this issue.
When the interlaced DCT or motion estimation options are enabled, sometimes the video is corrupted. I can't find any consistent pattern to when this occurs, except that the first recording after the backend starts is usually fine.
This has been discussed before but is still unresolved: http://svn.mythtv.org/trac/ticket/2061 http://www.gossamer-threads.com/lists/mythtv/dev/218736
If needed, I would be happy to do testing and upload sample videos.
Note: See
TracTickets for help on using
tickets.
I think this has been resolved in trunk, at least I can no longer reproduce the corruption there.
This functionality is fully contained within ffmpeg and was probably fixed by one of Janne's ffmpeg merges.
Bottom line:
It will stay as it is in the 0.21 -fixes branch and YMMV still applies there but it is working in current trunk.
