Detailed Description
This class describes a Video4Linux2 based input component. The component accepts both MIPSYSTEMMESSAGE_TYPE_WAITTIME and MIPSYSTEMMESSAGE_TYPE_ISTIME messages. Currently there is no way to specify the desired frame rate, so the MIPSYSTEMMESSAGE_TYPE_ISTIME is the recommended message to use. Output frames can be YUV420P encoded, YUYV encoded or JPEG compressed.
