I am the owner of Raspberry Pi 4B with 2GB RAM and latest Raspbian OS.
I already did some basic testing with HTML5 FullHD video or with Youtube and 1080p video, but playback is jerky and definitely not smooth.
I tried legacy GL driver and also fake KMS with GPU memory is setup to 256MB. I tried different combinations but without success.
Is even possible to get what I want on RPi4?
My current CHROMIUM_FLAGS are:
