My fault here (+/-), I created a function to decode fourcc hex numbers to names and it returns V4L2_PIX_FMT_YU12 instead of V4L2_PIX_FMT_YUV420. I did not know they are synonyms. Anyway, it seems lib4l 0.5.9 (32-bit) is not working with Skype (32-bit) while lib4l 0.5.3 (64-bit) is working with Kopete (64-bit) patched to work with libv4l (no LD_PRELOAD). I will keep on trying to figure out why. > What is an other issue with skype is that it insists on asking 320x240, so > if the driver for your cam cannot deliver 320x240 and libv4l fails to make > 320x240 out of it in someway (see below) then skype will fail. > > libv4l will crop 352x288 to 320x240 especially for skype, and it will > downscale 640x480 to 320x240 for the same reason. The driver delivers 320x240 as default. -- Lamarque V.
