Hi all, I hope you can bear with me a bit and help me with a few basics. I've been piggybacking on a couple of other recent threads, and googling my brains out, but I'm still at the stage where I don't know what I don't know, so I'm chasing my tail a little. I thought I'd break down and start a new thread with a couple of my basic questions.
First basic question: How do I know if I'm using XvMC? I've got an nVidia 5200 based video card. My readings lead me to believe that this is not something that is "settable" in my xorg.conf or via nvidia-settings. Is this something that must be enabled/disabled when mythfrontend is built? Further clues: - I *do* have a "Use libmpeg2 for decoding" choice in my mythtv General Playback settings page. The help text says this setting is "unavailable" if using XvMC. I normally take "unavailable" to mean that the choice is disabled (i.e., greyed out), but it's not -- I'm allowed to check the box. - second clue: doing ldd /usr/bin/mythfrontend doesn't show any XvMC related libraries linked. My tentative conclusion: I *think* this all means my mythfrontend (standard ubuntu distribution, 18.1) wasn't built with XvMC support, but I've had a helluva time trying to verify that fact. Am I on the right track? If so, is it worth trying to build mythtv myself to get XvMC? Will it likely lead to improved quality (my main issues are with fast-moving scenes, like a football game)? I've got a pretty powerful box with plenty of CPU, so that's not really a motivation for me. A related question is: can you still select custom de-interlacing and filters when you DO have XvMC enabled? Next basic question: If I'm displaying on a regular SD TV, is de-interlacing actually relevant? From my (uninformed, newby) readings, I thought de-interlacing was for displaying on progressive scan devices, but lots of advice seems to suggest using de-interlacing even for regular SD TVs. I'm confused. Thanks for bearing with me!
