CoreAVC drops frames though low cpu usage

[kimiraikkonen]

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!
