@tessus
Thank you very much for your feedback.
Currently SVT-HEVC does not have a support for MAC OS, however, we welcome contributions for adding such support.

we welcome contributions for adding such support.

What exactly would this entail? Is it just the build script that needs to be adjusted, or does assembly code have to be re-written?

from svt-hevc.

no assembly code to be re-written, I believe it would be some cmake / build scrip changes along with some compiler flags to make sure the code builds, after that it should just run.

Ok, I think I can have a look at it. Although it will take a while, because I'm currently rather busy.

However, I do have a few questions / comments:

• a more detailed documentation would be nice how to build the library (the build script is great, but doesn't really explain any of the options. some people would like to know what the different cmake options mean and do.)
• how do I currently build a static library (on Linux)?
• do I have to use the --enable-nonfree option for ffmpeg? If so, I cannot distribute this library with my static ffmpeg binaries (which would be a shame, because there was already a request to add it to my binary)
• I suggest you open a PR with ffmpeg to add the wrapper to the ffmpeg code base

@mypopydev what is your insight about the 3rd and 4th question from @tessus?

from svt-hevc.

Yep, I really would like to hear the answers, otherwise it makes no sense for me to get it working on macOS and then not being able to actually use it.

@tessus
I apologize for the late reply, please find below my answers:

• For point 1, could you please create an issue, stating which options do you need clarity on ?
• This should be feasible by changing the CMake files of the library to create a static and link it to the application, if you require assistance with this, please add a separate issue for this item too.
• Definitely not, not even gpl is needed, we'll be addressing this in the next commits, this is a free library licensed under the BSD+Patent license and so you can use it as you wish.
• This is already in progress, we have already opened the PR and are working on feedback from the ffmpeg community.

@hassount Thank you very much for your reply.

I will open separate issues for item 1 and 2.

Definitely not, not even gpl is needed, we'll be addressing this in the next commits, this is a free library licensed under the BSD+Patent license and so you can use it as you wish.

I've noticed that the --enable-nonfree has been removed from the README.txt. Thanks.

This is already in progress, we have already opened the PR and are working on feedback from the ffmpeg community.

Have you already sent the new patch to the ffmpeg-devel mailing list?

So, I've got it to 94%, https://travis-ci.org/1480c1/SVT-HEVC/jobs/499613916#L549 however I am erroring out at Undefined symbols for architecture x86_64:. It would be nice if someone could help. My knowledge of C comes from stackoverflow and looking at some man pages, on windows.

Idk if my modifications would actually work since I'm basically looking if the same headers from linux are present on Mac and changing #if __linux__ to #if __linux__ || __APPLE__ for some and I had a rough time with cpu_set_t.
