The supported resolutions are: 160x120 176x144 320x240 352x288 640x480 The Color Space/Compression reported by the driver is only one: RGB 24 The driver also uses these files which may (or may not) be related to used compression: iyuv_32.dll, msh263.drv, msyuv.dll, tsbyuv.dll In standalone mode, the camera records video in MJPEG format. Controls: Banding Filter - 50Hz/60Hz - bandwidth 3/4/5/6/7 (default=50Hz, 3) Brightness - 0..255 (default=128) Contrast - 1..8 (default=1) Saturation - 0..8 (default=1) Sharpness - 0..255 (default=0) Hue - 0..360 (default=0) I added some more logs to http://www.rainbow-software.org/linux_files/spca1528/ different resolutions (with default control settings): usbsnoop-video-capture-160x120.log usbsnoop-video-capture-176x144.log usbsnoop-video-capture-352x288.log usbsnoop-video-capture-640x480.log 160x120 with one control changed (other are at default values): usbsnoop-controls-brightness-226.log usbsnoop-controls-brightness-43.log usbsnoop-controls-contrast-5.log usbsnoop-controls-hue-91.log usbsnoop-controls-saturation-4.log usbsnoop-controls-sharpness-145.log opening controls window with no capture running: usbsnoop-open-controls.log -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
