Bug 494334 – media-video/ffmpeg and media-video/libav - ?

• Product: Gentoo Linux
• Status: RESOLVED CANTFIX

[Description Chris 2013-12-15 13:49:57 UTC]

Hi,

I'm noticing that the ffmpeg and libav condundrum is really making things impossible for me on my system.  I cannot seem to to get makemkv and xine-libs (and other packages the REQUIRE ffmpeg) and handbrake, which requires libav installed -- and of course, you annot have both.

This is just a request to developers to for support so that end-users can create a multi-media system that can use one or the other.  I really don't care which, ffmpeg or libav, Gentoo decides to support, but the choice should be all-encompassing to avoid these types of conflicts.  

Perhaps you are on your way with this already, but It was suggested to me by a developer that I make a request here, so here it is :)

Thanks.

For me ffmpeg works fine with all your listed programms and many, many more ...

I was too fast, i forgot:

Usually if something appears to "force" one or the other, it's due to an unmet USE requirement, or a keyword mismatch.  All of the packages you have mentioned can use ffmpeg or libav, as long as the version and USE are right.  Admittedly, sometimes portage is unclear when you just need a minor USE or keyword change... and it suggests installing the alternate package, rather than fixing USE/keywords.

But all of these applications DO support both.

[Comment 5 Chris 2013-12-17 02:38:07 UTC]

I hear what you are saying, but here's the thing.  I have removed everything from package.keywords.  I have +ffmpeg in my make.conf, and -libav.  I have run an emerge -uDN @world --with-bdeps=y, ran my deplcean, my revdep-rebuild etc. to make sure my system is entirely consistent -- and it is.

This is what I have installed:
media-video/ffmpeg-1.0.8  USE="3dnow X aac alsa amr bluray bzip2 encode hardcoded-tables mmx mp3 network oss pulseaudio sdl truetype v4l vorbis x264 xvid zlib -3dnowext -aacplus (-altivec) -avx -bindist -cdio (-celt) -cpudetection -debug -doc -examples -faac -fdk -flite -fontconfig -frei0r -gnutls -gsm -iec61883 -ieee1394 -jack -jpeg2k -libass -libcaca -libv4l -mmxext -modplug (-neon) -openal -openssl -opus -pic -rtmp -schroedinger -speex -ssse3 -static-libs {-test} -theora -threads -twolame -vaapi -vdpau (-vis) -vpx" FFTOOLS="aviocat cws2fws ffeval fourcc2pixfmt graph2dot ismindex pktdumper qt-faststart trasher" 0 kB

virtual/ffmpeg-0.10.3  USE="X encode mp3 sdl truetype x264 -gsm -jpeg2k -speex -theora -threads -vaapi -vdpau"

And when I go to install handbrake, I get this:

emerge handbrake

I do not see any option to compile handbrake with ffmpeg support instead of libav, therefore, I do not see any use flags I can maniuplate to make handbrake happy.  It always wants to pull in libav.  So, I reverse my use flags, and tried to force my system to use libav instead of ffmpeg, which makes handbrake happy, butmakemkv tells me that it MUST have ffmpeg, and does not work with libav.

I don't see how this can be done.  What am I missing here?

Thanks.

Handbrake's dep says:

    ffmpeg? ( || ( >=media-video/libav-9:= >=media-video/ffmpeg-1.2.1:0= ) )

You aren't allowing a new enough version on media-video/ffmpeg yet.

[Comment 7 Frank Krömmelbein 2013-12-17 08:12:14 UTC]

Analysis by Ben Kohler is correct, you need a newer ffmpeg version installed.
As you can see under Comment 1, ffmpeg-1.2.4 runs fine here.

It is possible that you have to add more of your installed programms to your package.accept_keywords file to get out of the "dependency hell" ;-)
