Normal Google Meet Present is optimized for slides/docs which is a very different problem than streaming video.
- giovannibajo1 6y agoWell, it’s still a joke that Google Meet will stream desktop / windows at 4 FPS. I would be curious to know whether they really think the feature is good enough.
- londons_explore 6y agoThis is mostly a limitation of Chrome and other web browsers. When streaming the desktop, the browser doesn't get notified when some region on the screen changes. That means it has to retrieve a bitmap of the screen and 'diff' it with every frame, which is computationally heavy.
- giovannibajo1 6y agoFWIW, AirPlay can send a H264 video of my desktop at 60FPS with ~0% CPU impact (hardware accelerated), good enough to play many games on TV.
- londons_explore 6y agoI believe Airplay has special OS integration - a third party app wouldn't have access to the screen buffer with zero-copy.. A third party app would at a minimum have to copy the data to system memory and back to the GPU, using a lot of CPU time for that alone, before any encoding.
