As Gabe pointed out in my post with compiled ffmpeg Linux binaries, there is a relatively simple method of adding libmp3lame.so.0 file to your shared hosting so that ffmpeg executable will see the library:

You can upload libmp4lame.so as well to the shared hosting site and when you call ffmpeg, call something to set an environment variable right before the call to ffmpeg i.e. in php I’d do exec(”export LD_LIBRARY_PATH=/path/to/lib/with/lame; /path/to/ffmpeg [ffmpegargs]”); That way you can use the uploaded lame. I hope that helps someone as I have been unable to find any info on how to use an uploaded lame. I’ve tried it and it works on godaddy.

Hope this helps.

Update: here’s libmp3lame.so.0.0.0 (from slackware 2.4.x, lame-3.97). I have no idea if it’ll work in your (shared hosting) environment; it is provided AS IS, use at your own risk etc. I can only state that the archived binary file at the moment of upload was indeed libmp3lame.so.0.0.0 from my elderly Slackware with 2.4.x kernel.
