HOWTO: Install and use the latest FFmpeg and x264

[FakeOutdoorsman]

Edit; the alt. would be to build fdk-aac as static only, don't know enough about it to say
(./configure --disable-shared

It should be static like the others. I'll test and update it later today.

mc4man, that sudo ldconfig resolved it. Thanks a ton.
Maybe the guide needs to be updated with this

[FakeOutdoorsman]

I updated the guide. It is now static so running ldconfig or monkeying with any environment variables are now not required.

One more thing FakeOutdoorsman
Under the FFmpeg compile section, in ./configure --enable-x11grab is missing. It only says to omit for servers but I did it for a desktop and now I got a
"Unknown input format: 'x11grab'

One more thing FakeOutdoorsman
Under the FFmpeg compile section, in ./configure --enable-x11grab is missing.

Thanks for the notification. It was listed in the configure originally, but it appears someone removed it (it is a wiki) and I didn't notice when I cleaned up their mess. I'll add it again.

...I did it for a desktop and now I got a
"Unknown input format: 'x11grab'

Can you show your ffmpeg command and the complete console output?

[cannon_dt]

Sorry fakeoutdoorsman.
I fixed the problem by reinstalling ffmpeg. So I dont have the complete console output
However the command I used is

ffmpeg -f alsa -ac 2 -i hw:0,0 -f x11grab -r 30 \
        -s $(xwininfo -frame | grep -oEe 'geometry [0-9]+x[0-9]+' | grep -oEe '[0-9]+x[0-9]+') \
        -i :0.0+$(xwininfo -frame | grep -oEe 'Corners:\s+\+[0-9]+\+[0-9]+' \
        | grep -oEe '[0-9]+\+[0-9]+' | sed -e 's/\+/,/' ) \
        -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0 -threads 0 \
        -y ~/Public/screencast/aa_screencast_baking.mkv

Hi
In the wiki for FFmpeg it shows:-

./configure... --enable-libopencore-amrnb --enable-libopencore-amrwb ...

I think that libopencore-amrwb is only a DEcoder, not an ENcoder.
ffmpeg -codecs shows:-

 DEA D    libopencore_amrnb OpenCORE AMR-NB (Adaptive Multi-Rate Narrow-Band)
 D A D    libopencore_amrwb OpenCORE AMR-WB (Adaptive Multi-Rate Wide-Band)

Doesn't it need vo-amrwbenc to be compiled and installed to enable amr-wb encoding?

I have compiled from here ---> http://sourceforge.net/projects/open...les/vo-aacenc/
But it looks as though there's a git version here ---> https://github.com/mstorsjo/vo-aacenc
(libvo-amrwbenc-dev is in the repo for Oneiric-Pangolin-Quantal)

Yes, I believe it is a decoder only, but I've never used it personally.

You can use vo-amrwbenc as an encoder in ffmpeg. Just compile it and then add "--enable-libvo-amrwbenc --enable-version3" to your ffmpeg ./configure. I haven't checked to see if it is in an Ubuntu(+1) repository yet.

vo-aacenc is another AAC encoder. Did you mean this: https://github.com/mstorsjo/vo-amrwbenc.

Thanks for the tip. Maybe I'll add it as a dependency, but I don't know how useful it would be for the general public.

Yes, that's the one.
I posted the wrong links, my bad.

x11grab isn't working for me. I've installed ffmpeg using the tutorial on the wiki, and ffmpeg seems to work, except for x11grab

For example, if I try

ffmpeg -f x11grab -i hw:0 test.mkv

I get this

ffmpeg version N-35113-g509f502 Copyright (c) 2000-2012 the FFmpeg developers

Any help?
