* [new branch]      ffmpeg4x   -> origin/ffmpeg4x
Already up-to-date.

Has this become live? Just did pull git.

This branch is 14 commits ahead of master.
Or is this in progress to become master, and should I wait until Master = ffmpeg4x . Lost it for now

My build shows:
Avidemux v2.7.1 (180721_34fdf5673e4) and does match Master branch 34fdf5673e4?

The ffmpeg4x branch includes my recent work (https://avidemux.org/smif/index.php/topic,18406.msg84542.html#msg84542) on migrating Avidemux to FFmpeg 4.0.x just to prevent that it gets lost if my computer suffers a HDD crash or such. It should compile and most features should work (now including sound and VDPAU hw accel), but as of now, many project scripts generated with the current git master or releases would be incompatible due to changes in FFmpeg structures.

The purpose of the branch is to keep these changes off master for a while. It might be merged into master at a later point.

If you have a computer with Intel graphics (no NVIDIA graphics card) running Linux, you could help by providing feedback whether the libVA hw accel still works with the ffmpeg4x branch.

FFmpeg 4.x requires nv-codec-headers for NVENC to be available. These are as it seems not yet "officially" (by Canonical or from the universe repo) packaged for Ubuntu. There are PPAs for that (https://launchpad.net/~mc3man/+archive/ubuntu/prop4me) (this one for 18.04 (https://launchpad.net/~mc3man/+archive/ubuntu/bionic-prop)) or just install from git (https://askubuntu.com/questions/778100/how-to-install-compile-nvenc-in-ubuntu).

Would this work with internal FFmpeg (avidemux)?

QuoteAt the moment these headers must be installed as well as FFmpeg from git to get access to nvenc and friends.

It needs only the headers.

OK, will look at this next days, time permitting.

I would need the full /tmp/logbuildCore, the excerpt you've posted doesn't contain the actual error.

Thank you. No idea ATM what is going wrong, will investigate later. Builds fine on Fedora 28.

QuoteFFmpeg version of headers required to interface with Nvidias codec APIs.

Corresponds to Video Codec SDK version 8.1.24.

Minimum required driver versions:
Linux: 390.25 or newer
Windows: 390.77 or newer

installed from https://git.videolan.org/git/ffmpeg/nv-codec-headers.git

First of all, we won't find the NVENC header in /usr/local/include where it is installed by the Makefile in nv-codec-headers by default, please apply the attached patch.

I installed Ubuntu Bionic from the most recent daily image in a VM using gnome-boxes, installed git, cloned the Avidemux git repo, checked out ffmpeg4x branch, ran

bash createDebFromSourceUbuntu.bash --deps-only

installed the nv-codec-headers from git, libass-dev, liba52-0.7.4-dev, libmad0-dev, libmp4v2-dev, patched cmake/admCheckNvEnc.cmake and ran

bash bootStrap.bash --prefix=/usr/local --with-system-libass --with-system-liba52 --with-system-libmad --with-system-libmp4v2

which succeeded impeccably. The resulting Avidemux build runs fine.

The log is obviously unchanged. My last post implied that the build failure you see doesn't happen on a clean up-to-date Ubuntu 18.04 install. Do you have old Avidemux headers still installed somewhere in the system? Please remove them prior to running bootstrap script. I would also remove Ubuntu universe provided ffmpeg headers (libpostproc-dev, libavcodec-dev, libswresample-dev etc.) if they are installed on your system.

Please try the attached patch.

Big time shortage, and getting worse next months, probably not getting at this stage.

It's a pity. I've pushed the patch to the branch as is.
