Recently, I had been having a problem with enabling Intel's new acceleration mode, SNA, as described on the wiki. It dropped 74 frames in eight minutes as my logs show. WIth it disabled, I get no dropped frames and perfect video playback. One small disadvantage is that chromium-pepper-flash now tears using uxva. However, having proprietary software work is not nearly as big an issue as mplayer2 not working.
I was wondering where I should file this bug upstream? It seems like it may be a driver issue, or maybe an issue directly related to mplayer2 because VLC did not seem to drop frames. I would love to help it get worked out. With SNA being enabled by default in Ubuntu 13.04 (not sure if that means the necessary configuration option in xorg.conf is included, but probably) this seems like an issue that should get resolved. Is this reproducible for anybody?

What OS are you using now?
Its not a bug in SNA, but its something to do with fontconfig. search the forums.

I'm using archlinux.
Having tested with and without hardware acceleration set to SNA, I can confirm that passing "--nofontconfig" to mplayer2 resolves the frame drop issue. Why this is? I am not sure.

So is this a bug in mplayer(2) or in my fontconfig? Is it that mplayer needs a font in "~/.mplayer"?

There is an fontcofig update in testing. You don't need to configure ~./mplayer.

I shouldn't need to configure ~/.mplayer, but I do because fontconfig is in testing, not extra
Edit: Looks like the new fontconfig comes with its own issues though.

I installed mpv from the AUR and the problem has gone away. My configuration has been simplified to just set the channels and vo=opengl.
Using opengl-hq causes some judder. It *should* work with this video card right? Mesa 9.1 has opengl 3+.
