[GnomeMeeting-list] Newbie UPDATE: slow video

["Paul Nixon" <khobar95 hotmail com>]

Well, I'm not sure what to say at this point. I've just completed some
testing between Linux GM and MSNM and I'm really puzzled. Please understand
this is NOT a complaint or rant or anything like that.

I have GM installed from RPMs on a Mandrake 8.0 system. Capture card is a
Hauppauge WinTV PCI. I'm running Gnome with X4.0.3 and an ATI Radeon PCI
card. System is a 1.2GHz Athlon Tbird.

I have Netmeeting 3.0 installed on two other machines, an 800MHz TBird with
GeForce2 MX AGP and another 1.2GHz Tbird with a Kyro II AGP. Both of these
systems run Win98SE, but the 800MHz Tbird also has Mandrake 7.2 installed
with a 2.4.3 kernel.

Here are the results:

GM -> NM. Good quality audio, poor quality video until the blocks disappear.
After blocks are filled in the video quality is fair at best. Any sudden
movement in the source frame causes breakup. Max 2fps.

NM -> GM. Fair quality audio, fair quality video. Blockiness in middle of
frames. GM locked up after about 10 seconds consistently. Approx 4fps.

NM -> NM. Excellent quality audio, excellent quality video. In fact the
video was full motion all the time with quality almost as good as the
original with only some blotchyness associated with compression.

All of this was tested over a 100mb LAN with the systems no more than 8 feet
apart in the same room. No external transmission (direct IP link).

So what in the heck is going on here? Is there some compression algorithm I
have to add to the Linux machine? Is it possible there's some weird problem
with resizing the video window or something? I know when I ran Kwintv I was
unable to get smaller than 320x240 without some odd things happening (would
resize vertical but not horizontal).

This is just weird.

BTW, the 1.2GHz Linux system has not had any modifications done to it.
Straight install from the Mandrake CD.
