nvEncodeAPI.h is no longer available in ffmpeg at the location pointed to by cross-compiling.txt, do I need to find an updated one or is the one that I downloaded from ffmpeg version 3.4 fine to use?

But why not submitting the new filter upstream?

What does this mean?  If it means submitting the filter to the main project, I don't know how to do that!

I forgot to update the instructions, this and other headers are now provided by https://github.com/FFmpeg/nv-codec-headers

If you have a NVIDIA graphics card capable of encoding H.264 and maybe even HEVC and want to be able to use this capability from Avidemux, then you need a recent version for use with recent NVIDIA graphics drivers. Otherwise you don't need the header at all.

Clone the repository (already done) Actually, create a clone of Avidemux repository fork mean00's Avidemux repository to your GitHub account

https://help.github.com/en/articles/fork-a-repo

clone this repository, configure git to know about you (name, email address etc.) and the upstream repository, create a new branch, add the files belonging to the filter and other files you have modified, write a commit message, push the branch to your GitHub account, submit pull request from there.

Regarding nv-codec-headers, installation of these headers in MXE amounts to just removing @@PREFIX@@ (as the prefix is empty) from ffnvcodec.pc.in, stripping ".in" from the filename, copying the edited file into the usr/x86_64-w64-mingw32.shared/lib/pkgconfig subdirectory of MXE for 64 bits builds and copying the folder "ffnvcodec" to usr/x86_64-w64-mingw32.shared/include/

I can't seem to get the NVENC to be included.  I added the updated file to both the i686 and x86_64 .shared include directories, and did mkdir out and chmod 775 out in both .shared directories.  I would like to use this feature.  Thanks for your explanation of nv-codec-headers, I've got it working now!

I wasn't able to copy just the libADM_vf_blend.dll to the installed version, but I didn't expect that to work anyways

Also I modified the max bitrate the GUI allows in https://github.com/mean00/avidemux2/blob/master/avidemux_plugins/ADM_videoEncoder/ffNvEncHEVC/ADM_ffNvEnc.cpp#L205 from 50000 to 400000, 50000 is too small
I use the slow preset for NVENC on ffmpeg, I would love to attempt to add some more options to the config

Also also I forked the repo and will pull request my changes when I'm happy with my plugin.

(edit: Misunderstanding removed)

You can't mix output of different compilers, but if the installed version was built with MinGW, I would expect the binary of your plugin to work. Obviously, it can't work with a VC++ build like the official release version.

Great to hear that!

I've uploaded several clips, which I've put together in a playlist:

Do I submit the pull request to master?Very cool, this is the first project that I have contributed to on github!
