  1. What help do you need?

My setup is working ok. I’m streaming via webrtc using a RPI4+GStream+Arducam. This is my pipeline:

pipeline_str  = ''' webrtcbin name=sendrecv bundle-policy=max-bundle
v4l2src device=/dev/video0 !
video/x-h264,profile=high,width=1920,height=1080,level=3.0,framerate=30/1 !
queue max-size-time=100000000 ! h264parse !
rtph264pay mtu=1024 config-interval=-1 name=payloader !
application/x-rtp,media=video,encoding-name=H264,payload=96 ! sendrecv.'''

My problem is that the profile parameter does not work. No matter what I put as a profile, I see the same stream quality. I can even put as profile a dummy, e.g. “asdasd”, that it works fine, making me suspect that the profile parameter is just not being considered.

I want to change the profile because the stream is not very good in quality. The bitrate seems very low. For example, streaming at 1080p I measure only a download transfer rate (at the client site) of about 1mb/s, which is quite low for a 1080p stream.


We also have a lot of work that is higher priority at the moment.
I will try to help you in my free or off hours.

Thanks. I’ll appreciate it. I’m stuck with this problem and can’t move on. :frowning:

Hi @Edward,
Any news on this matter?
