How does commenting out the "1 || " part affect this problem?

Re: Intel 82852 & Xv
Okay - I've done some digging and found the problem...
To recap, our application decodes MPEG-2 video into a video window and draws
overlays on top of the video. The problem was that the two seemed to
"fight", causing the overlays to blink every time the video was refreshed
(ie - 30 Hz or so)
The following code is from the 4.4.0 X server source, i830_video.c, line
1416:
/* update cliplist */
/*
* XXX Always draw the key. LinDVD seems to fill the window background
* with a colour different from the key. This works around that.
*/
if (1 || !REGION_EQUAL(pScreen, &pPriv->clip, clipBoxes)) {
REGION_COPY(pScreen, &pPriv->clip, clipBoxes);
xf86XVFillKeyHelper(pScreen, pPriv->colorKey, clipBoxes);
}
This code seems to be the offender... If I comment out the whole if block,
things work as they should - the video is drawn into the YUV buffer, the
overlays are drawn into the RGB buffer, and things blit together OK.
I'm by no means a driver expert, but by the looks of the comments above this
block of code, it looks like there was a bug in LinDVD that was worked
around in the driver...
Now - another somewhat related problem. When the MPEG-2 software is
decoding and displaying video, at times video is drawn outside the video
application in random blocks on the screen (ie - in terminal windows, on the
desktop, etc.) This seems to happen whether the above mentioned block is
commented out or not, so I don't think I introduced the bug.
Does anyone have any suggestions?
Thanks
Mark

Re: Intel 82852 & Xv
Hello again I have an application running on this machine that decodes MPEG-2 into a window and then draws overlays on top of the video using a colorkey. This works on other hardware combinations (ie - an Intel 810, anything nVidia, etc), but on this machine the XvPutImage that performed by the MPEG-2 encoder and the draw commands for the overlays fight with each other, causing a blinking effect... I've seen this before on the SMI chip, and one of my co-workers modified the X server to fix it for me - it had something to do with the X server and the driver not negotiating the YUV format correctly - something about the YUV data not being drawn into the overlay buffer - sorry - I just can't remember the nitty gritty details. Does anybody know if and how this problem could be addressed?

Thanks very much Alan - that did the trick... I forgot that the Intel chips use system RAM and that the value can be changed... Thanks again!

Re: Intel 82852 & Xv
Mark, Basically, it looks like you are out of video memory because you have set VideoRAM to 16384 in your config file. Bump that up to 32768, and try again. Alan.

Intel 82852 & Xv
Hi All I have a laptop with an Intel 82852/855GM Integrated graphics chipset. The machine is running RedHat 9 with the new 4.4.0 X Server. I'd like to use the XVideo extension on the machine, but xvinfo reports that no adaptors are present. The X server log file says: "I810: Disabling Xv because the overlay register buffer allocation failed" So, this looks like it may be the problem, but I'm no X server expert when it comes time to solve it... Is it possible to make Xv work on this chipset? If anyone has any ideas I'd appreciate them... Thanks in Advance Mark Mark Cuss, B. Sc.
