Streaming USB camera from i.MX6 to Notebook through network

ScottKerstein — Tue, 14 Oct 2014 02:49:48 GMT

Using the Nitrogen6X with attached USB camera as a SERVER, I am able to play through the pipeline using this command.

root@nitrogen6x:~# gst-launch-0.10 v4l2src device=/dev/video0 ! 'video/x-raw-yuv,framerate=(fraction)30/1' ! ffmpegcolorspace ! vpuenc codec=6 ! rtph264pay ! tcpserversink host=192.168.40.63 port=5000

So, I know I am 1/2 way there, but I am having a little trouble getting the video to stream on my Notebook CLIENT using Gstreamer. On my Linux box, I have tried various combinations of the gst-launch command found within the community but get an error.

What would the corresponding CLIENT command be to launch Gstreamer and see the video?

Thanks.

Thank you, that was quite helpful, but needed to add "async-handling=true" to prevent from getting stuck during PREROLLING

scott@Linux-Dev:~$ gst-launch tcpclientsrc host=192.168.40.110 port=5000 ! jpegdec ! autovideosink async-handling=true

I changed to vpuenc codec=0

However, display window does not launch on CLIENT even though CLIENT and SERVER pipelines are both PLAYING

What would prevent the video box popping up in Linux on this network stream? It works if I attach the webcamera to my Notebook and stream video using gst-launch, but does not act the same with network streaming for some reason.
