porting libaom
Hi Matthew Oliver, first let me tell you how thankfull I am that you share all your work necessary for porting ffmoeg and its libraries to VS. That was extremely helpfull for me!
Have you had a look at "libaom", the library that provides the new AV1 video codec? I believe it is an important addition to ffmpeg.
It was actually easy to build the aom-project with VS using the cmake option in VS-2017. Unfortunately the "CMakeLists.txt" file produces only *.exe files, since all the libraries in the project seem static. I am certain that it is possible and maybe easy to do the same with dynamic libraries, but I do not have the slightest idea, how to modify a cmake-file.
Do you have any plans to integrate libaom into the ShiftMediaProject collection of libraries? Best regards, Peter
libaom is on the shortlist of libs to add support for. But it may be a little while before I can get around to it (gotta pay the bills first ;))

Have you tried adding "-DBUILD_SHARED_LIBS=1" to the cmake command line? Even though the README.md for aom says that this flag is officially not supported on Windows, I was able to produce .dll files for almost all Windows projects (only test_libaom does not link, complaining of an unresolved external symbol aom_codec_av1_cx_algo). I haven't yet tried using those .dll's from FFmpeg, though.
Hi Luke,
yes, I think I did try something like: "-DBUILD_SHARED_LIBS=1. I do not remember exactly, some tip from the internet. Unfortunately I did not succeed.
I have now created a VS-project from scratch, for the AOM libs, which works well. Since I will have to modify the AOM code that additional effort was OK.
Best Regards
Hi Peter, you might want to edit your personal details out of the previous reply, so they don't stay forever on GitHub for spammers to collect!
