[ubuntu] Audio LAVC, couldn't find encoder for codec libfaac.

[RabbieBurns]

since reinstalling with the new ububtu my commandline for re-encoding isnt workin with mencoder, im getting this error:

 

Audio LAVC, couldn't find encoder for codec libfaac.

 

ive installed libfaac0 and libfaac-devel

 

my command is

 

mencoder $f -oac lavc -ovc lavc -of lavf -lavcopts aglobal=1:vglobal=1:vcodec=mpeg4:vbitrate=2500:acodec=libfaac -af lavcresample=48000 -vf scale=320:240,harddup -lavfopts format=psp -ofps 30000/1001 -o  $f.mp4

 

and it used to work fine

Just done a quick google and found this:

 

[sOLVED] [HELP]Mencoder doesnt wrok after update!! - Ubuntu Forums

 

The only thing you could try from that post is:

 

use -oac faac instead of -oac lavc.

[RabbieBurns]

that seems to be it going now.. hopefullyy itll output a playable file.. cheers

[AdamK]

No problem, glad to have been some help

[RabbieBurns]

file encoded ok but playback doesnt have any audio

[AdamK]

I've just had a play around with it on my Fedora machine.

I got the same error as you with lavc.

I then tried faac and it encoded it but the sound was very poor.

 

I then tried using mp3lame instead and that seems to work fine.

 

Give that ago and see if that works ok for you

HOWTO: Easily enable MP3, MPEG4, AAC, and other restricted encoding in FFmpeg - Ubuntu Forums

 

I think this thread answers my questions

 

Will report back ASAP

[RabbieBurns]

Note: Right now there is no way to encode AAC audio with FFmpeg from the Karmic Koala repository. You will have to compile FFmpeg yourself to do so. Refer to option A. Compile FFmpeg yourself if you would like to encode to AAC audio with FFmpeg. Another option is to use a separate encoder and then combine the video and audio.

 

Is the key

 

Then I had to

svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg
cd ffmpeg
./configure --enable-gpl --enable-nonfree --enable-pthreads --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab
make
sudo checkinstall --fstrans=no --install=yes --pkgname=ffmpeg --pkgversion "4:0.5+svn`date +%Y%m%d`" --default

 

Now it works if i do:

 

ffmpeg -i input.avi -acodec libfaac -ab 128k -ac 2 -vcodec mpeg4 -s 320x240 -vb 500k output.mp4

 

Im not sure if ive solved my original problem or just found another way to do it?

[RabbieBurns]

I find it amusing that I google a problem Im sure Ive had previously, and my original post about it is the number 1 hit on Google.
