Default CoreAVC drops frames though low cpu usage

Hi there,

I've been using CoreAVC+CoreAAC+Gabest MP4 splitter to decode AVC (.mp4) files. However though cpu usage is almost free (it doesn't go higher than %35), i see frame drops when i view "Video Info" by pressing "Alt+3".

This especially happens when i'm browsing with Firefox 3 at the same. If i leave the video alone, it rarely happens. My video card is old Geforce4 MX 440 with 64MB DDR memory, however this frame drop happens while watching low-res videos such as 320x240@30fps.

So, is GPU card the reason? I'm watching AVI videos encoded in Divx/Xvid codec also MPEG2 videos, they're just fine, as they're not CoreAVC, as well.

Note: I'm using "Internal Video Renderer(default) in Bsplayer.

Thanks!

Though nobody answered, i found out that the frame drop occurs when i use Bsplayer with "Internal Overlay Renderer(default), but fine with Overlay Mixer. So?

So use overlay mixer. Seems your videocard deals better with this rendering methode.

I found out, not only AVC, WMV or MPEG, when running in "internal overlay renderer" and if you use some other GPU-eating programs like firefox, the further drops i noticed in ALT+3 statistic page.

The bad thing, if i switch to "Overlay Mixer", some of videos like MPEG are failed to open in bsplayer at startup sayin "unhandled exception...error". If i say continue, it plays but that makes me nervous.

It's annoying and weird about inconsistencies of Bsplayer and rendering modes.

From this thread "Real (average) fps is lower than labeled one" it appears that kimiraikkonen still uses an earlier BS.Player-version than 2.21.950 of begin May 2007 (unfortunately the exact version/build-number used not mentioned sofar). This - regrettably - makes it hard/trivial to test or verify and/or even to derive any consequences from his findings as reported by him with respect to "inconsistencies of Bsplayer and rendering modes".
