Video processors run at a very low framerate when tab is in background

[KaelWD]

• I have verified that the issue occurs with the latest twilio-video-processors.js release and is not marked as a known issue in the CHANGELOG.md.
• I reviewed the Common Issues and open GitHub issues and verified that this report represents a potentially new issue.
• I am not sharing any Personally Identifiable Information (PII)
  or sensitive account information (API keys, credentials, etc.) when reporting this issue.

Code to reproduce the issue:

Publish a track with the default background blur processor, then switch to another tab in the same window.

Expected behavior:

My video should still be published at the full framerate.

Actual behavior:

Other participants see my video running at <1fps until I focus the video tab again.

Software versions:

• Browser(s): Chrome 92.0.4515.159
• Operating System: Kubuntu 18.04 (kernel 4.15.0-154)
• twilio-video-processors.js: 1.0.1
• Third-party libraries (e.g., Angular, React, etc.): Vue 2.6.12

Hi @KaelWD , sorry for a late reply. We have a plan to work on this and it will be part of a future release.

Hi @charliesantos, when are we planning for this fix? or if there is any work around that we can do as of now for this?

[RaquelRodrigues93]

Hi @charliesantos, any updates on this issue? or, like akashmehra99 asked above, any workarounds?

[dimagoltsman]

will this be ever implemented? its actually pretty unusable this way

[prashantlaheri]

Will we have any improvements in this area?
Because fps drops to 0 and it's pretty bad.

Issue also occurs with twilio-video-processors.js: 2.0.0 and with twilio-video.js: 2.27.0 (latest versions as of today).

Got a reply from Twilio representative that there is no timeline for a fix.

Hi @KaelWD!

Thanks for reporting this issue.

We added some performance improvements to the version 3. To resolve this issue, we recommend updating to the newest video processor version. If you continue to experience problems after upgrading, please let us know, and we will be happy to assist you further.

@luisrivas thanks for the response. Is 3.x ready to consume? I see that's it's still in beta. Does Twilio recommend this beta release for production use?

Hi, @jpodwys!

As the last release is a beta version, we are diligently working to gather and address as much feedback as possible. You can still use this version for production, and we anticipate releasing a stable version in the coming days based on the latest beta updates.
