Hello there,
I’ve been working with 2 ISP cameras for a rtsp video stream with this working example.
Using the test-multicast.c example… this is the pipe that works.
gst_rtsp_media_factory_set_launch (factory, "( "
"nvcompositor name=comp sink_0::xpos=0 sink_0::ypos=0 sink_0::width=1920 sink_0::height=2160 sink_1::xpos=1920 sink_1::ypos=0 sink_1::width=1920 sink_1::height=2160 ! nvvidconv ! video/x-raw(memory:NVMM) ! nvv4l2h264enc bitrate=60000000 ! h264parse ! rtph264pay name=pay0 pt=96 alsasrc ! audioconvert ! avenc_aac ! aacparse ! rtpmp4apay name=pay1 nvarguscamerasrc sensor_id=1 ! video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1 ! nvvidconv flip-method=2 ! video/x-raw(memory:NVMM),width=1920, height=1080, format=RGBA ! queue ! comp. nvarguscamerasrc sensor_id=0 ! video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1 ! nvvidconv flip-method=2 ! video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1, format=RGBA ! queue ! comp. " ")");
Now, i wanted to try different cameras, this time are USB. I made some changes but i got an error i’m not able to find anywhere.
Error: unsupported transport RTP/AVP;unicast;client_port=59496-59497
Here’s the new pipeline.
gst_rtsp_media_factory_set_launch (factory, "( "
"nvcompositor name=comp sink_0::xpos=0 sink_0::ypos=0 sink_0::width=640 sink_0::height=720 sink_1::xpos=640 sink_1::ypos=0 sink_1::width=640 sink_1::height=720 ! nvvidconv ! video/x-raw(memory:NVMM) ! nvv4l2h264enc bitrate=60000000 ! h264parse ! rtph264pay name=pay0 pt=96 alsasrc ! audioconvert ! avenc_aac ! aacparse ! rtpmp4apay name=pay1 v4l2src device=/dev/video1 ! video/x-raw, format=(string)YUY2, width=640, height=360,pixel-aspect-ratio=(fraction)1/1, framerate=30/1 ! nvvidconv flip-method=2 ! video/x-raw(memory:NVMM),width=640, height=360, format=RGBA ! queue ! comp. v4l2src device=/dev/video0 ! video/x-raw,format=(string)YUY2,width=640, height=360, pixel-aspect-ratio=(fraction)1/1, framerate=30/1 ! nvvidconv flip-method=2 ! video/x-raw(memory:NVMM),width=640, height=360, framerate=30/1, format=RGBA ! queue ! comp.

And this is the output from gst-device-monitor-1.0
