- mattermost/mattermost-preview docker image
- linagora/janus-gateway docker image
- we can hear sound, but the video doesn’t work. I find a lot of ‘Getting a lot of NACKs (slow downlink) for video’ warns in janus log. How can i solve this problem? Any suggestion is welcome.
Hi @wangzy,
Could you review this web page and send us the relevant logs, config files, etc. so we can diagnose this issue?
Additional details that might be helpful:
- What distribution and database is your Mattermost instance installed on?
- Which browser/desktop app (and version) are the two users using? How about operating system?
- Does the issue reproduce with more than one person?
- Does the issue reproduce each time, if you try to call the same person 2-3 times? (sometimes we’ve had issues in the past where first try doesn’t connect)
Can you also help take a look at the tips in these threads:
- mattermost is installed by docker. docker run --name mattermost-preview -d --publish 8065:8065 mattermost/mattermost-preview. The version is 5.3.0. janus gateway. I use image built by this source https://github.com/linagora/docker-janus-gateway. turnserver. I use docker image built by this source https://github.com/bprodoehl/docker-turnserver. I didn’t configure any ssl related things, we only use http and ws. and the outgoing insecure connection is enabled.
- we both use firefox browser, the version is 61.0.2 and 62.0. the operation system is macOS 10.13.6
- yes
- we tried many times, but it won’t work. we can hear sound from each other but no video.
There’s now a newly created WebRTC plugin for Mattermost, supporting one-on-one voice and video calls, developed by Nikhil Rajan.
There’s no third-party dependancy, and uses a browser-to-browser and serverless approach to initiate calls.
Feedback is highly appreciated!
