This reverts commit 672bd9bee5c0045694ef20fe3e2f7a003bef0edd. Reason for revert: Gmeet resolution dropped. When system starts Gmeet video call, it uses the hardware accelerated encoder as per the expectation. But, as soon as another system connects to the call, the immediate fallback observed from hardware to software encoder. Due to this, Gmeet resolution dropped from 720p to 180p. Currently, this issue observed on AlderLake-N SoC based fanless platforms. This issue is not seen on fan based systems. BUG=b:246535768,b:235254828 BRANCH=None TEST=Built and tested on Alderlake-N systems. With this revert Gmeet resolution drop not observed.
