VLC @2.2.2: build fails when using recently released ffmpeg-3.0

[dbevans (David B. Evans)]

Build fails due to the use of long deprecated API that has finally been dropped in this major release. See ​FFmpeg doc/APIchanges for the details of FFmpeg API changes/deprecations over time along with suggested alternatives.

(Updating the VLC-devel port to the latest git commit may help.)

Build fails as follows. Full build log attached.

Build log showing build failure when using ffmpeg 3.0

[RJVB (René Bertin)]

The newer VLC port I'm maintaining more or less actively is here: #49051

It looks that FFMpeg's build system provides all the hooks required to maintain parallel concurrent installations, up to and including the addition of a suffix to libraries and binaries. I'll try to find some time to exploit this and create a proof of concept implementation that I'll also be able to use to check VLC against FFMpeg 3 .

[RJVB (René Bertin)]

So I made a PoC implementation of a port:ffmpeg-30 that uses a combination of ffmpeg's --*-suffix and --*dir configure arguments to provide an ffmpeg 3.0 installation in parallel to the main/official ffmpeg 2.8.6 installation. After patching VLC's configure.ac so it uses the suffixed libav* (etc) pkg-config scripts, it turned out that version 2.2.2 rejects ffmpeg 3.0 :

    PKG_CHECK_EXISTS([libavutil < 55],, [
      AC_MSG_ERROR([libavutil versions 55 and later are not supported.])
    ])

one can work around that check, and the code will build without further errors, but the resulting application is crippled (won't even play MJPEG videos).

So it looks that VLC at least will remain stuck on ffmpeg 2.8 for the time being, and I'll be applying those PoC modifications to the current (2.8.6) ffmpeg port.

For those who understand German (or are willing to use google translate) here's a ​rant from a FFmpeg developer.

​More thoughts on another forum.

From ​slashdot:

Correct, the latest stable release (VLC 2.2. 2) doesn't compile due to API changes on the FFMPEG side however the latest VLC in their Git repository works with it. I am the Gentoo proxy-maintainer for VLC, and I have looked at the changes to make VLC 2.2.x work with FFMPEG 3.0, and they're not trivial or backwards compatible. My recommendation for folks on Gentoo at least is to use VLC-9999 (the Gentoo name of the latest upstream commit) if you need FFMPEG 3.0. One other thing to note is that FFMPEG >= 2.9 also breaks hardware acceleration in VLC (i.e. vdpau or vaapi), and if you need those, either stay on FFMPEG 2.8.6 or switch to libav.
