gspca is around 10 years old and it pre-dates UVC. The 291 image chip can take higher resolution stills, but mine only has a 720P sensor on it. The 292 image chip has similar performance at 1080P.
I have wasted far too much time trying to get Allwinner cameras working properly and I won't touch them any more. Our current product uses a more advanced camera similar to this one: http://world.taobao.com/item/521668890252.htm?spm=a312a.7700714.0.0.ekoWOi#detail But these boards are too hard to interface with for casual use. The main advantage to these chips is that they can simultaneously provide three versions of the h.264 stream at different resolutions. The Sonix chips are single stream but far easier to use. This is cheapest, decent h.264 720P camera I camera I am aware of - $6.12 http://world.taobao.com/item/527850462938.htm?spm=a312a.7700714.0.0.d9CEzd#detail You would need to attach to it using Ethernet, USB access requires custom firmware. Here are all of the modes supported by the 291 chips. Note that it supports 720P30 h.264 this first mode is uncompressed, 480Mb USB limits it to 720P5 jonsmirl@terra:/work/gm/linux-3.3-fa$ v4l2-ctl -d /dev/video1 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Index : 0 Type : Video Capture Pixel Format: 'YUYV' Name : YUYV 4:2:2 Size: Discrete 1280x720 Interval: Discrete 0.200s (5.000 fps) Size: Discrete 640x480 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.050s (20.000 fps) Interval: Discrete 0.067s (15.000 fps) Interval: Discrete 0.100s (10.000 fps) Interval: Discrete 0.200s (5.000 fps) Size: Discrete 320x240 Interval: Discrete 0.033s (30.000 fps) Interval: Discrete 0.050s (20.000 fps) Interval: Discrete 0.067s (15.000 fps) Interval: Discrete 0.100s (10.000 fps) Interval: Discrete 0.200s (5.000 fps) Both MJPG and h.264 work at 720P30.
