So... by continuing hacking and playing with the driver I achieved the following:
1) At least camera is working on mplayer 2) By passing fps=30 and modifying the mplayer command 30 fps stream could be seen 3) Some of controls are working: - Brightness - Contrast - Red balance - Blue balance - Gamma - Sharpness (works, but I haven't noticed any change of the picture) Other controls, such as AWC, AGC, flips aren't working (invalid argument) 4) The whole image quality looks poor: - Image is sharp and some kind of stable "pixel net" is visible - Color transmission is incorrect: almost b/w; red & green colors are swapped. So if I direct the camera to the RED object, it is displayed as GREEN (anyone has ideas? probably image format or color space is incorrect). 5) When starting mplayer, fist 10-20 frames are corrupted and color garbage is shown. At the time, dmesg displays a bunch of following messages: usb 2-3: New USB device found, idVendor=0458, idProduct=704c usb 2-3: New USB device strings: Mfr=0, Product=1, SerialNumber=0 usb 2-3: Product: USB20 Camera sn9c20x: Iso frame 0 of USB has error -18 sn9c20x: Iso frame 1 of USB has error -18 sn9c20x: Iso frame 2 of USB has error -18 sn9c20x: Iso frame 3 of USB has error -18 sn9c20x: Iso frame 4 of USB has error -18 sn9c20x: Iso frame 5 of USB has error -18 sn9c20x: Iso frame 6 of USB has error -18 sn9c20x: Iso frame 7 of USB has error -18 sn9c20x: Iso frame 8 of USB has error -18 sn9c20x: Iso frame 9 of USB has error -18 sn9c20x: Iso frame 0 of USB has error -18 sn9c20x: Iso frame 1 of USB has error -18 sn9c20x: Iso frame 2 of USB has error -18 sn9c20x: Iso frame 3 of USB has error -18 sn9c20x: Iso frame 4 of USB has error -18 sn9c20x: Iso frame 5 of USB has error -18 sn9c20x: [E] Empty buffer queue. sn9c20x: Iso frame 0 of USB has error -18 sn9c20x: Iso frame 1 of USB has error -18 sn9c20x: Iso frame 2 of USB has error -18 6) Skype shows nothing at video setup page (at preview zone). Probably it is discouraged by first garbaged frames and gives up, whether mplayer tries to continue. --~--~---------~--~----~------------~-------~--~----~ Lets make microdia webcams plug'n play, (currently plug'n pray) To post to this group, send email to [email protected] Visit us online https://groups.google.com/group/microdia -~----------~----~----~----~------~----~------~--~---
