Just a quick announcement about a recently added feature:
The latest CVS now includes a version of libmpeg2 (http://libmpeg2.sourceforge.net) as an alternative to the FFMpeg-based video decoding. FFMpeg still handles the demuxing, but the video can be handed to libmpeg2 instead. This takes significantly less CPU on my test machines, so it's good for lower-end systems; my 450MHz Cube can finally handle SDTV.
On my P4 3Ghz, libmpeg2 and libavcodec seem to take about the same amount of CPU time, with libavcodec a tiny bit *faster*. Both are compiled with -march=pentium4 . I tested a 1080i clip and a 480i clip (both from ATSC sources). XvMC is definitely disabled, and mythfrontend prints out the message that it's using libmpeg2.
Am I doing something wrong, or is this expected?
