Me (and someone else) noticed a problem with the overlay becoming black or turned of if an other window is partially before the overlay and clipping rectangles are used.
I experimented with PCI latency for the saa7146 and found out, that using larger latency increases those problems and using smaller latency reducing it. Of course very small latencies are not suitable too, at a latency of 16 the overlay functions pretty stable, only if the obfuscation is at the right end of the overlay it is still vanishing. In other cases the overlay disappears after some time (usually less than 2 seconds) depending on the position of the obfuscating window upon the overlay. Not sure but in system log sometimes messages like this appear, but not directly if the overlay is disappearing: Feb 15 12:46:02 [kernel] saa7146: ==> calculate_video_dma1_overlay: illegal values: y: 0 h: 0 d: 16 b: 4096 base: -536870912 Is this a chipset or a driver bug? (Have a Lex BN815 mainboard which has an i815 chipset.) --- other remark regarding the overlay: while grabbing an image or using xv in an overlay-displaying application (as my kvdr) the overlay is turned back on by the driver accidently, therefore one needs to set it to a very small size that it does'nt disturb the xv-frame. At least i have no other idea what to do with the overlay if i don't want it to be seen. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
