<div id="mb_0">Hey Everyone,<br><br>I've been using Myth for about a
month now and have been having trouble finding a "perfect" mode for
watching 1080i broadcasts. I'm using the newest "testing" ebuild in
Gentoo. The closest I've come is through MPlayer, using:
<br><br>mplayer -vo xvmc:bobdeint -vc ffmpeg12mc -fs -zoom -monitoraspect 16:9 xxx.mpg<br><br>This
works great outputting to both 1080i and 720p, but I can't find an
equivalent in Myth, and obviously this won't work with live TV in
Myth. Running in 1080i with the standard decoder, no deinterlacing and
no xvmc in Myth gives me perfect video for about 10 seconds at a time,
but then I get a period of jumpy stuttering for a couple seconds,
almost like the frames are displaying out of order. I don't think this
is CPU-related, because I'm constantly under 50%. Maybe my refresh
rate is out of sync? <br><br>Running with xvmc with or without bob deinterlacing increases
my CPU usage and gives me tearing problems in 720p and 1080i. I can't
get the tearing to go away no matter how many different combinations of
the OpenGL vsync and nvidia-settings-rc vsync options I use. I'm
pretty sure xvmc is "working" in Myth because I've got the greyscale
OSD overlays.
<br><br>The best compromise I've made is to do kernel deinterlacing
without xvmc on 1080i material. But this only looks good for film
sources, live 60 fps interlaced sources look pretty choppy.<br><br>So,
basically, does anyone out there have a "perfect" (or even almost
perfect :) ) setup for watching 1080i that I haven't tried? Is it
possible that I really don't have xvmc configured right in Myth even
though I'm seeing the greyscale OSD?
<br><br><br><br>Thanks,<br><span class="sg"><br>Mike Rosack<br>
