ffmpeg question

Post by willruss1 » Fri Nov 14, 2008 5:35 pm

maybe a dumb question, but under ubuntu 8.04, i have just upgraded to v1.3.6 audacity and had already installed ffmpeg libs. when i attempt to setup audacity to use said libs, it says it can't find them, even if i browse directly to it. it found liblame just fine, but won't use ffmpeg even when shown directly where it is...

any help would be appreciated

I've not yet got it working myself, but just seen this post that may be of help: http://audacityteam.org/forum/viewtopic ... 245#p29157

I presume that you built Audacity 1.3.6 from source? It looks like you have to specify ffmpeg support in the ./configure options.

Excellent - any chance that you could write a step-by-step guide of what you did. I'm sure it would be a great help to a lot of people.

Short answer:

Make sure that libraries reside in "/usr/lib", then point the library to there. Atleast for me it worked. Libraries need to be in certain directories, so if you compile ffmpeg to e.g. "/usr/src/ffmpeg-52" and try to point to that directory from audacity, it just wont work.

And remember to get ffmpeg from svn (so that they really are 52.xx version, 51.xx wont do). Also if audacity crashes when trying to open AAC don't worry. Just update application launcher for aac and m4a files to point toward audacity and then try to open file multiple times in a row - after 2-6 tries it will open :D

ffmpeg supports only Low Complexity and Main AAC formats; with "faad" you can check in what format the file is you're trying to open is.

I could write longer version but I am lazy ;)
