Selur's Little Message Board

is possible to compile last version 2019 for osx ?
Thanks

In theory: Yes. (main pain would be to compile all the dependencies)
in praxis: No, since I don't own a Mac anymore.
-> No
Tried to get Mac OS X running in a VM but that failed too.

I would give it a try to compile it myself for OSX, and also explore the possibility to add avs2 codec, is it possible to have the compile script?

There is no compile script and I don't plan to release the source code for Hybrid itself any time soon.
Compiling Hybrid itself isn't a problem (installing XCode and Qt Framework, running qmake and make and that's it).
The problem is to compile all the tools Hybrid uses.
ffmpeg, mplayer, mencoder with all the dependencies (libbluray, xvid, ...), x264, x265, vpxenc, mplayer,....

Adding support for a new encoder without knowing the code would be a pain. (takes me ~8hrs; without knowing the code base it would probably take ~40hrs)

I thought about adding support for xavs2 a while back:
problem is the encoder doesn't support pipe input, so it needs to be fed with uncompressed video data which needs to lie on a hard drive which makes it totally uninteresting for me.

You are right, there are ways to compile xavs2 into ffmpeg, totally forgot about that.
Hopefully https://evermeet.cx/ffmpeg/ will add support for it too, since that ffmpeg version already contains the other dependencies Hybrid uses in ffmpeg.
So implementing xavs2 support would probably take me 2 weekends.
1st weekend writing some basic code
2nd weekend testing how exactly the options of xavs2 can be used in ffmpeg (https://www.ffmpeg.org/ffmpeg-codecs.html#Options-28).
