#6144 closed defect (fixed)

MPEG 4 interlaced DCT and motion estimation can cause corrupted recordings

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.

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.
