Your ffmpeg command is inefficient. Use this instead:

ffmpeg -rtsp_transport tcp -hwaccel rkmpp -hwaccel_output_format drm_prime -afbc rga -i "rtsp://admin:Admin707@192.168.1.64:554/h265/ch1/main/av_stream" -vf “scale_rkrga=format=bgr24,hwmap,format=bgr24” -f rawvideo -max_muxing_queue_size 1024 /dev/null

Thank you for your response. After running the command you provided, I encountered the following error. Is my environment missing some kernels?

Try this again.

ffmpeg -rtsp_transport tcp -hwaccel rkmpp -hwaccel_output_format drm_prime -afbc rga -i "rtsp://admin:Admin707@192.168.1.64:554/h265/ch1/main/av_stream" -vf "scale_rkrga=format=bgr24,hwmap,format=bgr24" -f rawvideo -max_muxing_queue_size 1024 /dev/null
