Gstreamer Interlaced Video RTP Streaming for iMX6

XXiao1z — Mon, 05 May 2014 15:55:23 GMT

Hi,

I have a progressive video I can stream it via RTP just fine.

I also have an interlaced video, I can capture it and play it back from a file, but I could never stream it with RTP:

gst-launch mfw_v4lsrc device="/dev/video0" ! filesink location=camera0.yuv

gst-launch filesrc location=camera0.yuv blocksize=518400 ! 'video/x-raw-yuv,format=(fourcc)I420, width=720,height=480, framerate=(fraction)30/1' ! vpuenc codec=6 ! rtph264pay ! udpsink host=192.168.1.90 port=5000 sync=false -v

The above works fine, however when I want to put the two together to do a similar live streaming(worked fine for progressive cameras), that never worked. I did have the VDI patched for interlaced, the key ERROR is : "gst_vpuenc_chain: Buffer size is not the same framesize of 518400"

gst-launch -v --gst-debug=2 -e mfw_v4lsrc device="/dev/video0" fps-n=30 blocksize=518400 ! 'video/x-raw-yuv,format=(fourcc)I42
0, width=720,height=480, framerate=(fraction)30/1' ! vpuenc codec=6 framerate-nu=30 bitrate=4194304 ! rtph264pay ! udpsink host=192.168.1.90 port=5000 sync=false -v
