The microphone is handled by another driver. We try to leave their stuff alone but maybe the two couldn't share the bandwidth properly.What driver is it ?The huffman algorithm is part of the JPEG compression. No choosing.Sorry I meant bayer...I'd really like to help you with the framerate but I'm not so sure about it either.I just change mplayer's 'fps' parameter, and the captured video seemed to reflect the specified framerate... So it seems that the problem is not a 'global bandwidth' problem, but rather related to the size of one frame. (because if I can do [EMAIL PROTECTED], I should be able to do [EMAIL PROTECTED] fps, right?)Does the infrareed stuff work, too?Yes I can capture myself in complete dark and see me on the captured video ;-) I tried vgrabbj, to take screenshots. I have tried every ''-F" possible value: 1 VIDEO_PALETTE_GREY Linear greyscale 2 VIDEO_PALETTE_HI240 High 240 cube (BT848) 3 VIDEO_PALETTE_RGB565 565 16 bit RGB 4 VIDEO_PALETTE_RGB24 24bit RGB 5 VIDEO_PALETTE_RGB32 32bit RGB 6 VIDEO_PALETTE_RGB555 555 15bit RGB 7 VIDEO_PALETTE_YUV422 YUV422 capture 8 VIDEO_PALETTE_YUYV 9 VIDEO_PALETTE_UYVY 10 VIDEO_PALETTE_YUV420 10 VIDEO_PALETTE_YUV411 YUV411 capture 11 VIDEO_PALETTE_RAW RAW capture (BT848) 12 VIDEO_PALETTE_YUV422P YUV 4:2:2 Planar 13 VIDEO_PALETTE_YUV411P YUV 4:1:1 Planar 14 VIDEO_PALETTE_YUV420P YUV 4:2:0 Planar 15 VIDEO_PALETTE_YUV410P YUV 4:1:0 Planar 16 VIDEO_PALETTE_PLANAR 17 VIDEO_PALETTE_COMPONENT And I was using libv4l2. I was always getting errors saying vgrabbj couldn't set the palette. I would be glad to help you for more tests, if you need it. Do you have an idea of how I could get screenshots in higher resolution?

About Bayer:libv4l decides on its own which palette is used. AFAIK you can't influence that. he only way to stop libv4l from using JPEG is removing it from microdia-dev.c and recompiling the driver.
Anyway - I don't think you want to use an uncompressed bayer stream since it needs a lot(!) of bandwidth.
