please enable x264 support

[Reinhard Tartler]

ffmpeg is capable of linking against x264. in ubuntu this is not done

[Reinhard Tartler (siretart)]

ffmpeg could in theory link against x264, but we cannot do so in ubuntu,
because x264 is in multiverse whereas ffmpeg is in main.

if ffmpeg could load x264 at runtime instead of at load time then we
could enable it. promoting x264 is a no-go, IMO.

[Reinhard Tartler (siretart)]

okay, for intrepid I have replacement package that enable h263, mpeg2video, etc.
please see https://launchpad.net/~motumedia/+archive, add that ppa and install:

apt-get install libavcodec-unstripped-51

that should bring back the missing encoders.

feedback on them is VERY appreciated if we want to have this package in intrepid/multiverse.

[Reinhard Tartler (siretart)]

fixed in intrepid

[m0rtal (alexander-nagorny)]

Actually, I can't confirm that it's fixed.
I still have ffmpeg linked against x264, even though I have latest libavcodec-unstripped-51 - ffmpeg still complains about missing h264 codec.

"I still have ffmpeg linked against x264" - sorry I mean h264

[Lionel Le Folgoc (mrpouit)]

Could you paste here the commandline you're using? You are probably using an old codec name ('-ac h264' instead of '-ac libx264').

[m0rtal (alexander-nagorny)]

Command line is actually generated by dvd::rip, so it's not me :)
The problem is described here: https://bugs.launchpad.net/ubuntu/+source/transcode/+bug/276519, and I believe current thread was born because of it.

How is the situation for Karmic? I got an Android phone and would like to encode some of my videos to h264 to be able to play them back on it. Here is the commandline with the error about the missing codec:

yves@viking:~/Videos$ ffmpeg -i movie.avi -aspect 3:2 -s 480x320 -vcodec h264 -b 480k -r 23.976 -acodec aac -ab 96k -sameq -pass 1 outputfilename.mp4

You probably haven't yet installed libavcodec-unstripped-52.

Hi Paul, I just installed it right now after reading your post. Unfortunately it does not change anything for ffmpeg. Or is it another executable which I am supposed to launch?

Please also have a look at comment #6:

I think you also need to change the name of the codec to libx264...

[Yves Glodt (yglodt)]

Thanks Paul, this got me one step further.

I did however not manager what to specify to get aac encoding work, even I installed libfaad/libfaac, but this is not the scope of this BR.

here my commandline for the archives:

yves@viking:~/Videos$ ffmpeg -i Le\ Diner\ de\ Cons.avi -aspect 3:2 -s 480x320 -vcodec libx264 -b 480k -r 23.976 -acodec libmp3lame -ab 96k -sameq -pass 1 outputfilename.mp4

Note that this is handled by libavcodec-extra now (Ubuntu 17.04)
