[AVTCORE] Hackathon: RMCAT (and CCFB) in Jitsi

[Jonathan Lennox <[e-mail]>]

Hi, all —

As I’m now at 8x8 working on the open-source Jitsi project (https://jitsi.org/ <https://jitsi.org/>), I’ve been working on modifying the Jitsi Videobridge to make it easy to adapt it for alternate bandwidth estimation algorithms.  I hope this could be a good environment to make running-code RMCAT testing and comparisons possible.

The API I’ve created is hopefully clean and simple, modeled on the one in the ns3-rmcat repo with some changes.  The code is written in Kotlin, so Kotlin and Java should work with it immediately, and native (C or C++) should be able to work through JNI.

The interface can be seen at https://github.com/jitsi/jitsi-media-transform/blob/master/src/main/kotlin/org/jitsi/nlj/rtp/bandwidthestimation/BandwidthEstimator.kt <https://github.com/jitsi/jitsi-media-transform/blob/master/src/main/kotlin/org/jitsi/nlj/rtp/bandwidthestimation/BandwidthEstimator.kt>.

I welcome any comments, and I’d love it if people could give it a try — I’d be able to help out to let people get a Jitsi meet environment working.

Furthermore, I’ll be attending the Hackathon in Singapore.  Is anyone else planning to attend, in person or remotely, to work on RMCAT or CCFB work?  I’d love to work with folks to try to get interop or testing.
