I just added a second HD receiver card to my MythTV box. To test both receivers, I opened up a Picture-in-Picture window. It was close, but it was a bit beyond my Athlon64 3200+'s capabilities. It was stuttering a bit on pans and dropping some frames.
Has anyone else done PiP with two HD streams? What kind of horsepower is needed? I suppose this would be a good job for a dual core system. A few questions/thoughts that I had on this are: - Can XvMC accelerate both video streams? I have an NVidia FX5200 card, with XvMC enabled, is it benefitting both channels? - Are the VIA / S3 Unichrome video chips available as standalone cards, rather than just integrated into chipsets? Or, do any of the other S3 cards that support the full MPEG2 decoding? These could greatly reduce the horsepower needed for decoding two streams. - Any other things to look into for MPEG2 acceleration? I noticed that mplayer, with XvMC, has quite a bit lower CPU utilization than MythTV. How about x86-64 mode, apparently ffmpeg is optmimized for x86-64, is there anything like this available, or in the works, for MythTV? _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
