Release 1.8.0 of Web SDK includes changes to support latest WebAssembly SIMD feature on Chrome 84+
This is supposed to bring improvements on CPU usage as well as probably improve video quality (we still have to determinate what we understand & mean by quality)
What is SIMD ?
For those who are not familiar with, here is a good technical explanation about what it is and what we can expect in term of improvement.
After performing few tests on our platform (with SIMD feature activated on all our web pages using Zoom), we could not notice any improvements.
Did we test it correctly ? Did we measure and monitor correctly ? Did Zoom really use SIMD in a correct way, did Zoom change the way to use CPU with the Web SDK or not ?
Many questions and that’s why i want to open that discussion here.
In particular i would like to clarify the following points with you (community & users as well as Zoom developers)
For Zoom developers:
- What kind of improvement this feature is supposed to bring for the zoom Web SDK ? (performances, support for 720p, etc.) (please let’s stay honest, the point of this thread is not to just promote new things by throwing a smoke screen but really help us to understand where you are going with the Web SDK)
- How can we - as users of Zoom Web SDK - monitor these improvements ? Clearly current Zoom Meeting Dashboard metrics are not working very well (it show video streaming for minutes even after a use left and its connection has been terminated for example) - not talking about the fact that we cannot monitor CPU usage there.
- What kind of tests did you perform ? Can we have access to them and their results ?
- SIMD itself enable to improve things, but only if you adapt your video encoder. So what did you do to be able to use SIMD and bring the improvement you mentioned ?
For Zoom community:
- Have you already tested SIMD improvements ?
- If so, how did you monitor it and what is your Zoom Web SDK use case(s) ?
- What do you expect as improvements ? (lower CPU usage due to better resource usage, still same CPU burst but enable to encode in 720p soon, no CPU usage improvement but more video stability, etc.)
