Can you help me solve it?
Thank you!

Hi

Could you be so nice and create a send only example from Test source,
Server > Browser without incoming streams from browser side?

I have tried but video is not playing on browser so a short example would be great.

Thanks

Hi @notedit , thank for your work, your code helps people who are new to streaming like me a big step forward.
With source as TestSource, FileSource; your code works perfectly, however with the source being rtsp, the code has a bug as below:

Code:

url = "rtsp://admin:[email protected]/cam/realmonitor?channel=1&subtype=0"
source  = RTSPSource(url)

# url = "9-7-2023-23-06_1.mp4"
# source = FileSource(url)

pc.add_stream(source)

Bug:

I see you already have parsebin.connect('pad-added', self._new_parsed_pad) but it doesn't seem to work. Please help me check this issue

Does it support RTSP + H.265 to WebRTC(VP8 or VP9)?

This is not necessarily an issue, but a request/question. I'm very interested in learning how to expand this example code to work across two machines. I apologize for my ignorance since I'm new to websockets and webrtc, but what do I need to do to have the video captured on one machine (say from v4l2src) and displayed on another starting from your code?

Thanks for any help and thanks for making your well written code available for others.

Hi @notedit,

My understanding is that you are the author of this project. Thanks for helping me to get the GStreamer WebRTC demo running using Python.

Looking at your repos I find that you have essentially have WebRTC work that is of interest to me. Some of it is actually what I am interested to do - a python based WebRC gateway etc.

So I am now keen to get a bit of understanding of what you are doing with WebRTC and if we have alignment in our project objective.

Regards,

Mohammad
