ffmpeg install used ./configure not libmp3lame

[flebber]

I have installed ffmpeg both from the medibuntu repositories and from the instructions here https://wiki.ubuntu.com/ffmpeg following both methods it shows. However it seems I cannot get past the "Unknown codec 'libmp3lame'" error.

I am sort of out of ideas. This is the line I using to test ffmpeg.
ffmpeg -i /home/flebber/Tovid/meg11-001.vob -f mpeg -vcodec h264 -b 800k -g 300 -bf 2 -acodec libmp3lame -ab 128k /home/flebber/Tovid/trial.mpg This is the output from it.

Any Ideas ? I am using kubuntu.

ffmpeg -formats 2>&1 | grep mp3

it shound show which encoder you must use

E = encoder
D = decoder

http://www.medibuntu.org has packages with mp3 support. I believe they have a nice walkthrough on installing it as well.

Sorry, just reread your message and you are using the medibuntu package. Let me drink some more coffee and take another look.

You are right Creative2 I can just change to ffmpeg -i /home/flebber/Tovid/meg11-001.vob -f mpeg -vcodec h264 -b 800k -g 300 -bf 2 -acodec mp3 -ab 128k /home/flebber/Tovid/trial.mpg
and it does work I was using libmp3lame as thats what I found on ffmpeg wiki.

# Just for reference if it helps someone

I also tried doing this export LD_LIBRARY_PATH=/usr/bin/lame; /usr/bin/ffmpeg idea from http://bogdan.org.ua/categories/nixbut that didn't allow it too work either.

Also used this how-to http://symbiotix.net/node/35
but wasn't able to get that working apparently needed to open up the FFMPEG Settings, under the ffmpeg command, I had to replace -acodec mp3 with -acodec libmp3lame from http://www.travistidwell.com/node/263 but I couldn't figure that out.

Anyway got it working using mp3 so thats cool thanks all.

the issue is this :

if you compile your ffmpeg many encoders have different name if you look at medibuntu's ffmpeg

i have written about this on a topic about aac but this can be done for every codec and so understand what kind of ffmpeg you have and if you can encode or not

how to check you version of ffmpeg and so understand if you CAN encode and HOW encode

execute in a terminal this : ffmpeg -formats |grep aac:

-IF YOU HAVE FFMPEG WITH NO SUPPORT FOR AAC : you will get



D aac ADTS AAC

here you can't see E= encoder so untill you have not ffmpeg with all supports you will not able to encode because you HAVE NOT Encoder

easy solutions

READ THIS https://help.ubuntu.com/community/RestrictedFormats?highlight=%28formats%29
if you turn on medibuntu repo and update ffmpeg and mencodder will be updated and will support every formats
https://help.ubuntu.com/community/Medibuntu?highlight=%28medibuntu%29





-IF YOU HAVE FFMPEG COMPILED FROM SOURCE you will get

as you can see here it has D= decoder (aac) and it has E= encoder ,name of the codec for compiled ffmpeg is libfaac

D aac ADTS AAC
EA libfaac
D A mpeg4aac

so you need to use

ffmpeg -i INPUT -ab 128k -acodec libfaac OUTPUT




- IF YOU HAVE FFMPEG FROM MEDIBUNTU REPO you will get


D aac ADTS AAC
DEA aac
D A mpeg4aac


so you need to use

ffmpeg -i INPUT -ab 128k -acodec aac OUTPUT



cheers
