## function
- support YUY2 or MJPEG format usb camera.
- support hardware h264 encode.
- wupport NV12 NV16 NV21 NV61 format mipi csi camera. (test max support 2560x1440)
- wupport NV12 NV16 NV21 NV61 format mipi csi camera. (test max support 4224x3136)
## Benefits of improvement
- RkCamRtspServer cpu usage
