When can bitrate, etc., be changed by VIDIOC_TRY_EXT_CTRLS? Any time during encode? Only before VIDIOC_STREAMON? My understanding is that VIDIOC_STREAMON should start actually processing frames, everything before then is configuration. If something needs to be adjusted then VIDIOC_STREAMOFF should be called, changes made, and then VIDIOC_STREAMON again. Is this correct? I didn't see anything in the documentation about this. Thanks. -Fritz
