H264 simulcast not working on ios

[papaz0rgl]

Hello, many thanks for you library which is very well done. Integration into my project has been really smooth. I have one issue with H264 simulcast. I try to produce 2 videos layers : let lowEncoding = RTCRtpEncodingParameters() lowEncoding.maxBitrateBps = 256_000 lowEncoding.scaleResolutionDownBy = 1

        let highEncoding = RTCRtpEncodingParameters()
        highEncoding.maxBitrateBps = 5_000_000
        highEncoding.scaleResolutionDownBy = 1

It works well with VP8 but with H264 it only produces one stream at 5M. Furthermore the resolution is quite low and doesn't delivers full hd.

What am I missing ? is there some specific configuration to be done for h264 ?

Thanks for your help.
