  • 2 laptops w/ *best built-in video webcam for not-great (such as dim) light* $4K each US
    Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. Frequent video conferencing. Light video editing/gaming/photo editing. Desired programs/games include FFmpeg, Avidemux, Fallout 4 / Cyberpunk 2077 @ 1080p/30 fps, Visual Studio, Photoshop, etc. However, I believe most laptops will run that software at least 'acceptably', and it appears most of the software is capable of at least running emulated on Apple Silicon - with Cyberpunk as the biggest exception as it won't run on the previously-released Apple Silicon devices & I haven't seen discussion of it on the announced 2021Q4 M1 devices.

    I installed the prebuild Mac installer from ffmpeg.org and even tried pip install ffmpeg ffmpeg-python. But no success so far...

    FFMPEG? I believe OpenCV itself uses ffmpeg to handle videos streams.

    `$(TARGET_SAMPLES)/filter/sample-vitc.avi` test file in https://github.com/FFmpeg/FFmpeg/blob/master/tests/fate/filter-video.mak, which you may have to build https://ffmpeg.org/fate.html#Using-FATE-from-your-FFmpeg-source-directory to get access to. That is one more sample.

    You might be wondering about step 5. Well that is pretty complicated. There are probably multiple ways to do this, but the way I did it is setting up a node js server with FFmpeg to encode the video and then relay the encoded video to Youtube. You can find the code for that HERE.
