Simulcast issues


I am trying to do simulcast with 3 layers, somehow it seems like the 3rd layer is just not working.

I do see the diff between levels 1 and 2, but the 3rd is not fired.

+                { scaleResolutionDownBy: 3, maxBitrate: 60000, maxFramerate: fps_low, scalabilityMode: "S1T3" },
+                { scaleResolutionDownBy: 2, maxBitrate: 750000, maxFramerate: fps_high, scalabilityMode: "S1T3" },
+                { scaleResolutionDownBy: 1, maxBitrate: 1500000, maxFramerate: fps_high, scalabilityMode: "S1T3" },

I do see all 3 layers are being sent. The mimetype is VP8

I would appreciate an example for best practices / example for simulcast with 3 layers :slight_smile:


It could help: Temporal layers are ignored

Thanks for the referral – but in my case, 3 are not working… :frowning:

mediasoup is not responsible of how many spatial or temporal layers the browser sends. That’s up to the browser based on codec capabilities, CPU usage and network conditions.
