Subject: i951 Xv playback uneven
Date: Tue, 26 Apr 2016 22:02:29 +0200 [thread overview]
Message-ID: <20160426200229.GC26959@florz.florz.de> (raw)
Hi,
with the drm-intel-nightly I am currently running, I am also seeing some
quite noticable stuttering in Xv playback. It's particularly obvious in
stuff like rolling credits. It's not directly a performance problem, as the
effect can be seen even in "stop motion" (i.e., frame by frame) playback:
Sometimes, no update happens, and then the next update "catches up", a bit
like some kind of double buffering sometimes fails to switch buffers.
Now, I haven't investigated this any further as I am getting the impression
that noone cares anyway (my mail with the debug info that Daniel requested
regarding some other problems has been almost a month ago and I got no
response to that at all) - I am happy to help where I can but I won't
invest any effort upfront if it's going to be ignored anyway, so please let
me know if you really want to look into this.
Regards, Florian
