QUESTION
We have a RTSP stream running. this is the gstreamer pipeline we use to run the stream.
...ANSWER
Answered 2022-Feb-07 at 18:18Your problem may be that nvv4l2decoder outputs into NVMM memory, but videoconvert can't read from NVMM memory. Try nvvidconv instead of both videoconvert and videoscale:
QUESTION
I have a c++ application that gets the video in RTSP and H264 format from a camera using gstreamer an re-sends the videos using webrtcbin. I have followed the example from this link and I can see the video trough firefox (with the tips suggested in this post), when use VP9 encoding.
The pipeline I have used is:
...ANSWER
Answered 2022-Jan-11 at 12:09One 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.
QUESTION
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.
(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)
Sdp details(Offer/Answer):
SDP
Offer
...ANSWER
Answered 2021-Dec-10 at 15:13If 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.
QUESTION
As the title says, I have a problem of getting dtmf digits from b-leg. When I call a queue in callcenter, the two legs can be bridged. But It doesn't have any reaction when I press '*7' on my b-leg telephone.
Here is the dialplan:
...ANSWER
Answered 2021-Nov-03 at 03:04I know how to fix it now. It's cause by freeswitch set 2833 dtmf send payload to 105 recv payload to 101, but the telephone still send 105 dtmf payload type to freeswitch. I modified 'rfc2833-pt' in sip_profiles/internal.xml to '105' and it worked for me.
QUESTION
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 handAfter 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:
...ANSWER
Answered 2021-Nov-16 at 04:29The 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:
QUESTION
As the title indicates using gStreamer or VLC I can get the video to show without issues with the command below
gst-launch-1.0 rtspsrc protocols=tcp location="rtsp://{USER}:{PASSWD}@{URL}:63554/axis-media/media.amp?videocodec=h264" short-header=TRUE ! rtph264depay ! decodebin ! fpsdisplaysink
I can set it as a Network Stream in VLC as below with similar results
rtsp://{USER}:{PASSWD}@{URL}:63554/axis-media/media.amp?stream=0&videocodec=h264
but janus (latest/stable: v0.11.3) configuration as below is unable to show the stream on the webpage
...ANSWER
Answered 2021-Sep-19 at 13:05Janus Gateway/Server just doesn't support interleaved mode. And with current implementation of RTSP support inside Janus Streaming Plugin (Curl based) it's almost impossible to add such support there.
QUESTION
I am trying to send an MP4 video through Pion WebRTC to the browser.
Using FFmpeg, I split it into an Opus OGG stream and an Annex-B H.264 video stream. While the video works fine, the audio keeps cutting in and out. It plays fine for a few seconds, then stops for a second, and continues.
This is the FFmpeg command I use for audio:
...ANSWER
Answered 2021-Aug-19 at 14:55The 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.

QUESTION
Am new to webRTC and am trying to create a react native app with video calling functionality using this tutorial here as an example to follow https://dipanshkhandelwal.medium.com/video-calling-using-firebase-and-webrtc-14cc2d4afceb
However i keep getting this error on iOS and on android the app just closes once i try to join a call. The error i get on iOS says:
...ANSWER
Answered 2021-Jun-05 at 06:38I guess you are trying to use firebase as a signalling medium and want to use react-native-webrtc for the video calling.
Here is the sample code I have for the same solution with the latest libraries and react-native version.
Firebase Installation React Native.
Just set up ios and android using this above link and then use the below code for reference.
QUESTION
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)
SDP examples below:
...ANSWER
Answered 2021-May-13 at 18:03Firefox 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.

Install rtcp
You can use rtcp like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
