Streaming between two DM365 using Gstreamer pipeline

Alexander Zamora

Hi all

I want to send video via RTP to another DM365, Im using the following pipelines:

Sender
gst-launch -v v4l2src input-src=composite always-copy=false ! video/x-raw-yuv, format='(fourcc)'NV12, framerate=\(fraction\)30000/1001, width=640, height=480 ! dmaiperf ! queue ! TIVidenc1 codecName=h264enc engineName=codecServer ! rtph264pay ! udpsink host=192.168.1.106 port=5000

Receiver
gst-launch -v udpsrc port=5000 ! ! rtph264depay ! TIViddec2 displayBuffer=true codecName=h264dec engineName=codecServer ! queue ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite sync=false contiguousInputFrame=true

The pipelines above do not give me any error, but then I execute them it shows me nothing.

Does anyboy have the correct pipilines?

     ,

    On GST sender instead of sending the data over RTP/RTSP can you just write video frames to memory and check they are valid frames?

    Thanks for your response, I appreciate  your help.

    Everything seems to be OK, actually I can see the buffer displayed(by the way it takes too long to fill the buffer) like this:

    Alexander ,

    Referring to your quote below , 

    Everything seems to be OK, actually I can see the buffer displayed(by the way it takes too long to fill the buffer) like this:

    Can you share the DM365 clock configurations for DDR/Encoder/Arm? 

    In the past I observed the issue with  combination of this clock configurations. We may have to fine tune these clock configurations to fix the issue.
