I have a usb camera that gave raw video as 'YUYV'. I want to use this raw video and encode with imxvpuenc_h264. sadly the imxvpuenc_h264 support I420 as input(SINK) format. which hardware plugin could i be used for conversion from YUYV to I420. The imxipuvideotransform module have Source pad capability of I420 but no Sink pad capability of YUYV.
