Testing VMIX SRT to VMIX SRT over the weekend, Worked very well, much better than older Teradeks

50i Decklink SDI > 1080 50p VMIX Encode > SRT 720 50p 2.5mbit > 1080 50p VMIX Decode > 50i Decklink SDI

The Motion looked amazing, looked like interlaced content :)

I was on 23.0.0.21 HEVC Looked Noticely worse than H264
I've since upgraded to 23.0.0.22 and HEVC looks to be better

The Audio Encoder is defiantly not working properly

I was transmitting 4 Channels of audio,
is the audio bitrate shared with all 4 channels??

64kpbs sounds like 32kbps
128 sounds like 64kbps
256 sounds like 128kbps

I have test wavs at 64, 128, 256, 384

Can we get more control of the SRT encoder, ABR and VBR options
In addition TCP/WEB API control of the entire SRT encoder options

Audio bitrate is shared. You can just use 512Kbps to achieve 128Kbps per stereo pair when streaming all 8 channels.

This makes sense, many thanks
