Testing ffmpeg4x

[Jan Gruuthuse]

From https://github.com/mean00/avidemux2
* [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?

[eumagga0x2a]

The ffmpeg4x branch includes my recent work 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 (this one for 18.04) or just install from git.

[Jan Gruuthuse]

Would this work with internal FFmpeg (avidemux)?

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

[eumagga0x2a]

It needs only the headers.

[Jan Gruuthuse]

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.

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.
