URL parameters to join Jitsi Meet with camera and or mic disabled

nwoodhouse · April 9, 2020, 9:46pm

Folks,

It would be handy to be able to join a conference with camera and or mic disabled if preferred - then the user could unmute it at their leisure. Does this exist? Something like:

meet.jit.si/meeting-refererence?camera=false&mic=true

Relatedly - coming soon is the ability to specify a parameter (hash) in the URL to enable the user to join a Jitsi Meet with a specified display name (see: Jitsi Meet - displayname via URL param?).

Use has params #config.something

github.com

jitsi/jitsi-meet/blob/master/config.js#L100




// Start the conference in audio only mode (no video is being received nor
// sent).
// startAudioOnly: false,


// Every participant after the Nth will start audio muted.
// startAudioMuted: 10,


// Start calls with audio muted. Unlike the option above, this one is only
// applied locally. FIXME: having these 2 options is confusing.
// startWithAudioMuted: false,


// Enabling it (with #params) will disable local audio output of remote
// participants and to enable it back a reload is needed.
// startSilent: false


// Video


// Sets the preferred resolution (height) for local video. Defaults to 720.
// resolution: 720,

github.com

jitsi/jitsi-meet/blob/master/config.js#L139


// Enable / disable layer suspension.  If enabled, endpoints whose HD
// layers are not in use will be suspended (no longer sent) until they
// are requested again.
// enableLayerSuspension: false,


// Every participant after the Nth will start video muted.
// startVideoMuted: 10,


// Start calls with video muted. Unlike the option above, this one is only
// applied locally. FIXME: having these 2 options is confusing.
// startWithVideoMuted: false,


// If set to true, prefer to use the H.264 video codec (if supported).
// Note that it's not recommended to do this because simulcast is not
// supported when  using H.264. For 1-to-1 calls this setting is enabled by
// default and can be toggled in the p2p section.
// preferH264: true,


// If set to true, disable H.264 video codec by stripping it out of the
// SDP.
// disableH264: false,

@damencho This is perfect - thanks. How can you specify multiple parameters at the same time? What would the delimeter be - &?

#config.c1=true&config.c2=false

Is there an option to join a meeting without being visible as participant (for recording a session with an external screen capture tool)?

Hey! Thanks for pointing me this way. Do we know from which version onwards these type of parameters can be used?

Thanks in advance!

@pyjon

Check out this post… Many details on this subject:

Thanks @Corby. I get how it works. But I ve realized that it does work on some jitsi instances and not on others. This is related to the Jitsi version and that’s why I want to know starting from which version it’s available

damencho · September 9, 2020, 1:52am

@pyjon Passing params like that have been working for years now. If some particular config option is not working with some older versions that may be the case.
What config params do not work for you with some versions? Looking at blame or history of config.js can reveal when some param had been introduced.

Thanks @damencho. This is something you gave me a hint with. My original question was:
While using parameters such as:

startWithVideoMuted=true
startWithAudioMuted=true
userinfo.displayName=“My_name”
roomPassword=“My_password”

I found that this works on some instances and does not on others:

https://meet.yapbreak.fr/IY1WHZZEO9KP3QWTHY6LWQWZ4G#userInfo.displayName="Jitsiboy" - WORKS
https://meet.nevers-libre.org/D8X5QV2FKL1I4P9GS8LWGBIPCK#userInfo.displayName="Jitsiboy" - DOES NOT WORK

And this repeats itself with the other remaining parameters.

Is there any way to know if this feature is available or not in advance before choosing an instance ?? And if so, starting from which version number.

damencho · September 9, 2020, 2:50am

No. Other than checking the instance version and knowing the version you need.

I don’t think this exist at all.

This was introduced in the beginning of April https://github.com/jitsi/jitsi-meet/pull/5834 but I search the code for it and found which commit introduced it … but if you use meet.jit.si you don’t need this as there is a prejoin screen where you can control mic and camera and input the displayname in advance.
