literally no point in using VP9 (literally)

>>51488363
Send me the video you're trying to encode and the settings on libvpx, because the last time someone claimed that vp9 is impossible to encode in I tried a random video and got 4 fps single threaded on a laptop CPU. That's definitely slow, but it's not that bad.

I'm using WebM for Retards, though, which is basically a frontend for ffmpeg plus AviSynth.

https://gitgud.io/nixx/WebMConverter

The source is a few MB-large AVI that's not even 1 minute long. It took a few minutes to convert.

>>51488438
I literally used the ffmpeg guide to do it:
https://trac.ffmpeg.org/wiki/Encode/VP9

And then I specified

-threads 1

for benchmarking.

>>51488536
Did you use a constant or variable bit rate?

>>51488363
The VP8 encoder is also slow as fuck.

>>51488553
I think the exact line I used was

ffmpeg -i input.mp4 -c:v libvpx-vp9 -b:v 1M -na -threads 1 output.webm

With the files obviously changed. Let me try it again with a short video and see what happens.

>>51488555
It's still far faster, though.

>>51488591
libvpx encoders are just slow in general compared to H.264 & H.265. Of course VP9 is slower due to being a more complex & efficient codec, but building a codec without violating patents is kinda difficult.

>>51488609
Will VP10 be even slower?

>>51488624
Due to rising complexity, properly.

Interesting, single threaded was around ~5 fps, but doing -threads 3 seemed to only spike my CPU to like 60%, and still it said 6 fps, which seems too low for using at least double the resources.

I'm not sure how the stdout works with ffmpeg but the 3 threaded test seemed to finish much quicker. I don't know if it was 3x quicker though.

>>51488663
Properly?

>>51488910
*probably
Dunno how that happened.

>>51488609
It's slow compared to x264. x265 is basically equally slow, though.

You can always try a higher speed setting to trade off some efficiency for framerate.

Oh fuck yes finally a Zeranoe binary for Windows which includes libvpx 1.5.0.

I remember getting 0.7 frames a second encoding on practically the highest possible quality two pass encodes with VP9. I'll try those placebo-level settings with this new library. It's supposed to hold some performance and quality improvements but I have no idea if they will make any difference here.
