Hi all,
This is a follow-on from my previous post re poor playback performance
of a H264 720p video clip.
In my configuration, I have three profiles
if res = 1920 x 1080, then vdpau with temporal 2x (fallback to advanced 1x)
if res is 1280x720, then no de-interlacing
if res < 1280x720, then advanced 2x fallback to (can't remember)
Do I need to specifically call out the 1280x720 resolution because I
know it is progressive and does not need de-interlacing?
Is mythtv clever enough to detect a non-interlaced video stream so as
not to turn on the de-interlacers?
If I attempt to de-interlace a non-interlaced video clip, does it
actually attempt to do so?
Many thanks
Phil
