I capture video 640x360 from excelent USB web camera (Logitech 910) and push it into vpuencoder:


gst-launch v4l2src device=/dev/video0 ! video/x-raw-yuv,width=640,height=360,framerate=15/1  ! mfw_vpuencoder codec-type=std_avc bitrate=800  gopsize=150 ! video/x-h264,width=640,height=360 ! rtph264pay pt=96 ! udpsink host= port=5000 sync=false


Currently result is awful. Is it possible to tune quality? I'm ready to raise delay and refuse from gstreamer to make direct calls to vpu.
