If you’re really worried about power use, you could switch to an itx motherboard with an soc laptop chip in it.

Visually lossless means I couldn’t tell an image difference even when pixel peeping with imgsli. Good enough means I couldn’t tell a difference in video, but could occasionally see a compression artifact in imgsli.

The VMAF results are purely objective measurements. You can read more about it here; https://en.wikipedia.org/wiki/Video_Multimethod_Assessment_Fusion

I consider the ‘good enough’ level to be, if I didn’t pixel peep, I couldn’t tell the difference. The visually lossless levels were the first crf levels where I couldn’t tell a quality difference even when pixel peeping with imgsli. I also included VAMF results, which say that the quality loss levels are all the same at a pixel level.

I know that av1, x264, and x265 all have different ways of compressing video. Obviously, the whole point of this was to get a better idea of what that actually looked like. Everything on the visually lossless section is completely indistinguishable to my eyes, and everything on the good enough section has very minor bits of compression only noticed when i’m looking for it in a still image. This does not require the same codec to compare and contrast with.

Frankly, for anything other than real-time encoding, I don’t actually consider encoding time to be a huge deal. None of my encodes were slower than 3fps on my 5800x3d, which is plenty for running on my media server as overnight job. For real-time encoding, I would just grab a Intel Arc card, and redo the whole thing since the bitrates will be different anyways.

From my blogpost, i’m using the following command to encode the video;

ffmpeg -i source.2160p.mkv
-map 0:v:0
-map -0:a -map -0:s -map_metadata -1
-c:v libsvtav1
-preset 3
-vf scale=w=1920:-2
-crf 23
dest.1080p.av1.mkv

Sure, but that is a choice that couldn’t be made without first checking how much space is saved by switching codecs. This helps with making that decision, but i’m well aware it is only part of the information needed.

Stolen. Thank you.

I did try to format the table here better. I used code blocks the first time, and it ended up being even uglier. After about four edit attempts i kinda just gave up. Tables don’t seem to exist as far as I can tell either.

Your experience with x264 just about matches up with mine. As long as I don’t pixel peep, crf 24 does a pretty great job of conveying the information. It also does a pretty great job of working with just about everything compatibility-wise. I don’t expect it to go away any time soon specifically because of that.

AV1 is super neat in that we can buy hardware accelerated encoding for it for really cheap using the Intel Arc video cards, and can be decoded by their latest CPU generation. It makes for a great choice for something like security camera footage where playback compatibility is good enough (you can play it in a modern pc), hardware encoding works with a 200$ card, and you save a lot of money using the video card instead of buying extra storage space.

Don’t bother transcoding 4k

i have a cheap 1650 that can do four 4k transcodes on the fly with no issue. It was a 100$ upgrade. Frankly, this is a bad take. Obviously every situation is different, but unless you have a family of twenty that you’re sharing your server with, 4k encoding is incredibly easy to do these days.

I checked my discord, and i think this is a case of discords shitty ui, not changing privacy settings. Yes, my checkbox in that exact location was allowing other people to find based on phone number contamination. However, when i visited the privacy page that i did know existed, that permission was still turned off for me.

Oh my god i love that.

Man-ish tush-u. It aint hard to see why the kid would grow to hate his name.

Manishtushu is nearly the worst name i have ever seen. Kids would absolutely wreck that guy all the way to college.

Gotta be careful with osmc. It has so much choice that breaking is entirely possible to do accidentally. I absolutely love my little 4k box.

Unless you switch to using crf, which tries to give a consistent quality level, damn the file size.

And it wouldn’t have gpio, would require at least a square foot of floor/desk space, and it would cost more to run. Price. Size. Gpio. Nobody is running their remote controlled car with a cabled desktop sat on it.

You’re funny. That makes the total 77$. Still not the 100$ + required accessories that a desktop needs.

Oh his point stands,

No it doesn’t. The power supply is 8$ and the case is 10$, from the official store. That’s 72$. Stop lying.

Not really. It’s made to run headless, and isn’t always used for compute tasks. I use mine for running servos. But accessories for the desktop are also not included, so your point doesnt stand regardless.

100$ isn’t cheaper than 55$. That’s 200% more than the pi. If someone is looking for a pi because of the price, a 100$ computer isn’t an option.

Is it $60 or less? Everytime one of these alternative boards with an assload of more features pops up, nobody bothers to mention the price. Obviously we could spend more money to get more features, that’s what spending more money does. You can’t replace something without actually offering an alternative. The pi’s biggest selling point was that it was cheaper than a steak dinner. If you dont match or beat that, you aren’t actually competing with the pi.
