Conference room data channel only reports audio updates

[VanIseghemThomas]

Title says it all. I'm currently implementing conference streaming for the Unity platform and everything works like a charm except one aspect. When opening a data channel I am only able to retrieve UPDATE_AUDIO_LEVEL and AUDIO_TRACK_ASSIGNMENT event messages. Causing me to have problems mapping the video tracks of joined users since the I cant get ahold of the VIDEO_TRACK_ASSIGNMENT_LIST for example, even when explicitly querying it using the signaling. This is the case for all other features such as camera, mic mute, chat events etc.

My first thought was that I did something wrong opening the data channel, but I'm clearly getting the audio events so there is in fact a data channel. Any obvious things that could cause this?

Hi @VanIseghemThomas

You can use the TRACK_LIST_UPDATED message to be able to get the updates. VIDEO_TRACK_ASSIGNMENT_LIST triggerers only your video track assignment change but it didn't trigger everytime someone enters in a room.

For example, if the maximum video track count is 3, there is 5 participants in the room and a new participant is joined, you won't get VIDEO_TRACK_ASSIGNMENT_LIST.

You can stick with TRACK_LIST_UPDATED and broadcast_object callbacks. For more information: https://github.com/ant-media/conference-call-application/blob/main/react/src/pages/AntMedia.js#L1379 and https://github.com/ant-media/conference-call-application/blob/main/react/src/pages/AntMedia.js#L699
