Look carefully at my sonix video parameters... notice that there are two /dev/videoX devices
This is done so that the screen display app can use the the uncompressed stream while forwarding on the h.264 stream without decompressing it. The uncompressed stream does not need much CPU to display. 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.
