Let's say I need an encoder that converts .flv files to 3gp files,how I'm going to compile ffmpeg to include the mentioned encoder?Thank you.

This is more becoming a question about how ffmpeg works. If you want to know what my ffmpeg package supports, simply run

Code:

ffmpeg -formats

and check if the encoders you think you miss are present or not. If you find an encoder missing you can report that back...

Your question on how to produce a .3gp file has already been answered in this thread, but maybe you just don't get it. So:

Code:

ffmpeg -i inputfile.flv -s cif -vcodec h263 -acodec libamr_nb -ac 1 -ar 8000 -r 25 -ab 12200 -y outputfile.3gp

will take an input FLV file and create an output 3GP file using H263 video and AMR audio encoders in CIF format (352x288 pixels).

Kino is another choice for creating 3gp files. If you prefer to work in a gui instead of a command line, I'd check this one out. Also, I didn't have to recompile ffmpeg to make this work (maybe ubuntu already had this built in though). Just open the video in Kino, and click on the export buttion and click on the "other" tab. There is an option for 3gp in the dropdown list. I tried this with my Chocolate 3 and it worked like a charm.
