[gentoo-user] ffmpeg command not found

[gentoo-user] ffmpeg command not found

[gevisz]

I used to convert dav to avi files with the following command
yet a year ago:
$ ffmpeg -i input.dav -vcodec libx264 -crf 24 output.avi
but now, while trying to use it, I get
> bash: ffmpeg: command not found

What happened?

I still have virtual/ffmpeg package installed.
In my case it points to libav.

From the ffmpeg website[1]:
FFmpeg is the leading multimedia framework ...
... It contains libavcodec, libavutil, libavformat, libavfilter,
libavdevice, libswscale and libswresample which can be used by
applications. As well as ffmpeg, ffserver, ffplay and ffprobe which
can be used by end users for transcoding, streaming and playing.

So  libav does not have all the stuff you want.

As said above read the news item it has important information about
this setting in Gentoo, anyway what you want is to have this in your
make.conf:

USE="... -libav ffmpeg ..."

Thank you for your reply.  I am aware of that change. But the news says:

"Users who currently use libav (the Gentoo default) do not have to
perform any action since USE=libav is enabled by default."

So, I "performed no actions".

And I still have media-video/libav-9.17 installed.

P.S. I have nor libav no ffmpeg USE flags in make.conf but I think
       that USE=libav is enabled somewhere in the profile. Am I wrong?

I think that should be read as "Users who want to continue using libav..."
There an avconv in libav that is mostly compatible with ffmpeg.

If you want to use ffmpeg instead of libav, "It should be noted that the
users still need to enable USE=ffmpeg on packages with optional libav
support as well. Users who want to use ffmpeg instead need to specify
USE=-libav in make.conf explicitly."

Otherwise, set USE=-ffmpeg in /etc/portage/make.conf to stick with libav.

This last part is wrong. The libav USE flag controls the choice between
ffmpeg or libav. The ffmpeg flag controls whether packages get built with
support for whichever of the choices is set by the libav flag, so you
still need the ffmpeg flag to include option libav/ffmpeg support.

Yeah, this was a colossal clusterfuck that was dropped on us a few
months ago. =(

A libav cultist decided to force it on everyone, you have to find the
relevant useflags (forgot which) and set it back to ffmpeg.

The only reason libav exists these days is because it serves as a
religeous idol for said cultists. I'm very disappointed that people are
still suffering from this.

What I wasn't sure is if ffmpeg will be removed in the future and gentoo will 
end up following debian, et al.

Et al can go rot in hell. We use ffmpeg.

There's been a discussion on the default switching back to ffmpeg on
-dev too.  I think I read that correctly.

Darnit, I just read this within the last week or so. Ah, here it is:

I think I read they are going to get input from the council at the next

libav (not ffmpeg) at least used to provide an ffmpeg binary. But libav
has considered this binary to be "deprecated". Did they (libav) drop it?
