            One possible reason browsers support only baseline profile encoded h264 streams. You can try fool browsers by add something like capssetter caps=\"application/x-rtp,profile-level-id=(string)42c015\" in between rtph264pay and webrtcbin, but it will help only in some cases.

            Webrtc on Python failing to change ICE connection state between peers
            Asked 2021-Dec-10 at 15:13

            First, I want to mention that I am very new to WebRTC, so any advice would be very helpful.

            Currently I am using aiortc library to build my own WebRTC app. Here is what I am trying to do.

            I have 2 peers, one is web browser, which is written in javascript, and another one is python script, which is working as signaling server and peer at the same time. So If you access to my web page, you will send video frame to server and then the server will make modification of that then send it back.

            So I finished testing my app on LAN environment and everything worked as I expected. But once I deployed my app to remote server (Google cloud run) , I encountered Ice connection state failing issue. And gets this log on remote server.

            enter image description here

            (I think it is due to disconnection between peers, not low memory problem. I tried with 16GB RAM and 4 cpus and still didn't work)

            Then, I dig into more information, and found that TURN/STUN server is necessary to build WebRTC app over Internet. So I added google STUN server to my RTCPeerConnection like this. [{'urls': 'stun:stun.l.google.com:19302'}, {'urls': 'stun:stun1.l.google.com:19302'}, {'urls': 'stun:stun2.l.google.com:19302'}] (I added both side on javascript and python because both side is working as peer) Unfortunately, it still didn't work.

            Now, I am planning to build my own TURN server, but I am afraid if TURN server wouldn't solve this problem. So I would like to have any advice from you since I am quite stuck within my situation.

            p.s I have done SSL encryption.(So GetUserMedia is working fine)

            If everything work on local, and this ice server are set, verify that your gcloud server have the correct firewall for webrtc port (not only your signaling port, check the sdp/ice you exchange). also this Webrtc page allow you to check is a stun/turn work on your client

            You will not need stun on your python side, as it's a server his ip may be public (unless you don't want to). Stun allow to find your public ip and allow the port to remain open.

            On your server you need to open your signaling port (certainly the WS where you exchange the sdp) and the P2P port (candidate lines in the sdp), the media/data will go through this one. For each media (sdp m line) there are usually one used port.

            Why am I getting "Failed to set remote video description send parameters for m-section with mid='0'" error in Android when it works in Chrome?
            Asked 2021-Nov-16 at 04:29
            Background Information

            Hi there, I am attempting to build a WebRTC client in Android that subscribes to a video feed that is being broadcast using NodeJS and JavaScript.

            The broadcaster code can be viewed in its entirety in this lovely article by Gabriel Tanner.

            It works beautifully when running it in localhost under the http://localhost:4000/broadcaster.html in Chrome and then visiting my IP Address from another device on the network. I can see the video and it is near real time.

            I have tried this using two different webcam devices, both a built-in and a USB webcam but the Android client does not work even though the JavaScript Broadcaster and Client works fine.

            The task at hand

            After following the tutorial and getting the example to work I decided to try and implement my own Android application for which the entire source code can be viewed right here on my GitHub.

            I have followed various tutorials around the place and the issue always stems from attempting to set the remote description which is done with the following bit of code:

            The error message was triggered due to the offer containing H264 codecs whilst the Android Client was not anticipating H264 and was not setup to encode and/or decode this particular hardware encoded stream.

            The fix was to ensure that the connection factory was setup as such:

            The problem in the end was an inaccuracy in the Sleep time caused by issue #44343 in Go itself. It caused the samples not to be sent at a constant rate, but at a rate that randomly was between 5 and 15ms off, resulting in a choppy stream.

            Sean DuBois and me fixed this in the latest play-from-disk and play-from-disk-h264 examples in the Pion repository by replacing the for-loop and Sleep() with a Ticker, which is more accurate.

            SDP issues: WebRTC connection fails Firefox but not Chrome
            Asked 2021-May-13 at 18:03

            I'm working on WebRTC streaming which streams video from a device to a browser. This streaming works in Chromium browsers just fine but fails in Firefox. There is a failure with the SDP exchange which then halts the rest of the connection (no ICE candidates sent after SDP exchange).

            There are some issues with Firefox's answer SDP I've found but I haven't discovered a reason for the issues: SDP mentions VP8 but we use H264 only; m=video 0 has port 0 but typically that's non zero; I typically get an a=inactive line; a=sendrecv should probably be a=recvonly; many other lines are missing (for example, ICE-specific lines)

            Firefox likely doesn't support the profile level id 0x4d4016. Then you have no codecs in common and the media is rejected (which is what port 0 means). Without any non-rejected m-line your connection will fail.
