Re: YouTube Videos in Chromium not Working on Raspberry Pi 4 B 4GB

I've set GPU memory to 128 MB and have not overclocked anything, and video works now. There is some lag (or uneven frame rate) in VLC for some videos compared to OMXPlayer (e.g. the built-in demo video), but that is perhaps not related to GPU memory.

Re: Raspberry Pi Imager 1.2 destroyed the microSD card, I believe

SD cards can and do wear out. Sometimes unexpectedly. Some are better than others. It can depends on the brand, the model, and if they are genuine or just fake copies. But this was the offical SD card from the RPI Foundation from summer of 2019 ─ it's probably the best quality. It's a very strange ...
