Re: Running Pure Debian on the Raspberry Pi 3B+?
Raspbian's pretty close to pure Debian I think, and has more hardware
drivers for the VC4, GPIO, Bluetooth. They made millions of them, the
software's pretty good. Try omxplayer and notice how busy the CPU
isn't. That's because it's utilizing the GPU in about the optimum
way. I have a Rock64 and smplayer on that uses the hardware
acceleration too. No, the Raspbian smplayer (16.11.0 (revision 8242))
isn't doing the acceleration right yet, it'll probably catch up.
Actually on the Rock it's the same version smplayer but it's arm64
Debian. Only omxplayer is fast I think. And if you read the man page
you can write little scripts like
#!/bin/bash
omxplayer -o local --win 448,272,1472,1040 $1
To use it with your choice of window size and audio output. No
screenshots though.
I have 2 Pis running Raspbian, and one running arm64 Debian using
https://people.debian.org/~stapelberg/raspberrypi3/ with updates and
upgrades. I think I prefer the Raspbian. I had to try 64 bit, but,
nah, it's not a significant improvement in this case. For one thing
64 bit is bigger and the Pi can only use 1 GB of RAM.
I'd maybe consider the Rockpro64 https://www.pine64.org/?page_id=61454
if I didn't already have a full house. But the software is in its
infancy, a lot doesn't work right yet and the documentation's in
Chinese. My Rock64's still experimental, not something I use everyday
like the Pis. I don't use a big computer at all, just Pis.

No, I won't call it "climate change", do you have a "reality problem"? - AB1JX
