Maybe a Simulcast generic question, but probably of interest anyway. I have set the usual three Simulcast scalings: 4, 2, 1. When camera video has a resolution lower than 720p, not all three layers are being encoded in Chrome, as pointed out in simulcast - consumer is selecting invalid temporal lay…

[image] piranna: Problems is, when setting layer two (index: 1) with consumer.setPreferredLayer({spatialLayer: 1}) , video has a videoHeight of 320, like scalings are [4, 2, 1] instead of [2, 1] . Just to confirm that you are passing proper encodings to the producer, enable spatial layer 0 in…

Just to confirm that you are passing proper encodings to the producer, enable spatial layer 0 in the consumer and check the received resolution. Do you mean consumer.setPreferredLayer({spatialLayer: 0})? That’s interesting, because doing so, the changedlayers event tells me that spatialLayer is n…

Check the mediasoup demo, please. I promise there is no issue here at all. This is super tested.

I was not thinking there would be a bug, but instead that being both zero and null “falsy” Javascript values, that there would be some kind of optimization there. We are using a (heavily) modified (old) version of EduMeet, that’s a fork of mediasoup-demo, so yes, it would make sense to take a look t…

Maybe related to this: Talking heads application, 352x288, strange scalable video coding - #7 by OllieJones Seems like a similar issue, specially at the end of this comment: [image] Talking heads application, 352x288, strange scalable video coding mediasoup libraries …

I have just compare current mediasoup-demo code with our own one. Both of them are getting total number of spatial and temporal layers with next code: const { spatialLayers, temporalLayers } = mediasoupClient.parseScalabilityMode( consumer.rtpParameters.encodings[0].scalabilityMode ); T…

You didn’t answer to this: Spatial layers has lower resolution - #2 by ibc I repeat: call consumer.setPreferredLayers({ spatial: 0 }) and check received video resolution. Yes, I say 0, so the lowest one. Then, rewrite your code with just 2 encodings instead of 3 and ese how it behaves. PS: There …

[image] ibc: I repeat: call consumer.setPreferredLayers({ spatial: 0 }) and check received video resolution. Yes, I say 0 , so the lowest one. I know zero is lowest one. I have already check with logs that when spatial or temporal are set to zero, the one set to zero is returned as null in th…

[image] piranna: That leads me to think: maybe should be check the resolution of the video track generated by getUserMedia() before setting the encodings array in transport.produce() , both by hand or by the produce() method itself, so in case the number of layers that Chome can generate for tha…
