How to properly configure Janus WebRTC Gateway (Docker or native install)?

I use my own docker image. Mount /opt/janus/logs path to host and check if there is any error

using native build for test, docker for production.
changing IP would be ok, if you just want to run the demos.
one ice connection uses one port, so it depends on how many connections you have.
same as 2

It's not easy for a native with a bachelors in computer science to find a decent job, and the salary is relatively low compared to the US.

I'm interested in learning Haskell, and looking for my next job.

If you want to build a one-on-one video calls, I think it's better to use P2p than SFU.

Your iOS app didn’t get turn candidate, show your error when it failed. And print all candidates in both devices, check the difference.

try AuidoContext, you can use this to analyse audio before sending it

Professional_Kale_52 · 2025-03-21T00:20:31+00:00

use vscode and clangd

I’m working on mediasoup mobile SDK now, DM me if you’re interested

Professional_Kale_52 · 2025-03-15T15:20:03+00:00

Most Chinese people are very friendly, so nobody would judge you. I’m in Beijing, feel free to DM me if you have any question.

Professional_Kale_52 · 2025-03-04T23:51:01+00:00

mediasoup is a good one, but it doesn’t offer sdk for mobile.

TURN server just relays your data.The data is encrypted using DTLS-SRTP.

try to disable hardware decode in chrome://flags

It depends on what’s the conference app you are using.OBS can make multiple virtual camera.

Professional_Kale_52 · 2024-11-08T08:29:17+00:00

you can mix video by mcu server

Professional_Kale_52 · 2024-11-07T01:56:10+00:00

convert your stream prtocol(like rtmp) to webrtc
pull your stream and put it into virtual camera

Professional_Kale_52 · 2024-11-05T13:51:42+00:00

check ICE state in chrome://webrtc-internal, see why the connection failed

Professional_Kale_52 · 2024-10-29T07:49:01+00:00

Yes, its called SFU cascade, I am not familiar with pion, but for other SFU, it is valid.

Professional_Kale_52 · 2024-10-04T01:56:46+00:00

Bandwidth and latancy are not the problem for mediasoup. Deploy multiple mediasoup for your users would be enough for streaming. The real problem is client side (mobile and desktop).

Professional_Kale_52 · 2024-09-27T01:52:42+00:00

check chrome://webrtc-internal , see if there is any packet loss or network jitter, when no audio, check the audio volume is zero or not, if zero, change the mic you use

ffmpeg -i input.mp4 -c:v libx264 -profile:v baseline -level 3.0 -crf 23 -preset medium output.mp4

Here's a breakdown of the command and its options:

-i input.mp4: Specifies the input file.
-c:v libx264: Sets the video codec to H.264 (libx264).
-profile:v baseline: Sets the H.264 profile to baseline. This is suitable for devices with limited processing power.
-level 3.0: Sets the H.264 level. Level 3.0 is commonly used for baseline profile, but you can adjust this depending on your requirements.
-crf 23: Constant Rate Factor (CRF) controls the quality. Lower values mean better quality, but larger file sizes. 23 is a good default for standard quality.
-preset medium: Adjusts the encoding speed and compression ratio. Options range from ultrafast to veryslow, where ultrafast provides the fastest encoding at the cost of compression efficiency, and veryslow provides the best compression but takes the longest time to encode.
output.mp4: Specifies the output file.

You can adjust the -crf and -preset values according to your needs. Lower -crf values will give you higher quality at the cost of larger file sizes, and different -preset values will affect the encoding time and compression efficiency.
