Is SVT-AV1 encoder implementation a planned feature?

[Execrated]

If not, if there a limitation that would prevent it from being added?

[Selur]

Yes it is planned.
Waiting for builds which support pipe input, since I'm not planning to support it while humongous temporary files are needed.
+ https://github.com/jb-alvarado/media-autobuild_suite/ doesn't support it atm. and there are some issues compiling it.

already appeared on the list svt av1

looking forward to update

[Selur]

Yes, I noticed that a few days ago, it's on my todo list, but I'm too busy atm. fixing bugs.
So once I fix the currently reported problems I'll try to look at it.

=> this will take quite a while, especially since there are LOTS of options.

btw. if you want to help, I'm looking for a few sub categories to split the 'AV1 Specific Options' into.
-> so if you (or anyone lese) knows enough about AV1 to sort them into sub categories (like MotionEstimation, RateControl, Partitioning or similar let me know)

Cu Selur

[Selur]

Btw. I just added SVT-AV1 support to my dev version with tons of parameters I'm not sure of what they do exactly.
So the general tool-tips will probably not really help much and I'm not sure I categorized each of the ~100 options correctly.

https://github.com/OpenVisualCloud/SVT-A...r_guide.md
and
https://github.com/OpenVisualCloud/SVT-A.../README.md
are nice, not always in sync with the command line help info, but all in all a great help.

One thing that I noticed is that the encoder is fast, but by default configured for top speed and once you change the presets it gets slow.

I really like svt hevc

and for me enough toolbox of svt hevc

I use your application exclusively for converting video on a separate PC
my settings for converting: constant quantizer, preset 


I've try gui for svt av1, it was horrible(((

[Selur]

send you a link to my current dev version which supports SVT-AV1, haven't had much time to test

works good,

But  progress bar does not visible for a long time(

I,ve test
