I have Linux server/workstation box which had ffmpeg compilled for it some time ago. Now one type of library for internet communication does not seem to work on one of the endpoints. I think that real problem is related to codec used by the endpoint. Only thing I have to do is recompile ffmpeg if that is the case.
However I don't know how to list all codecs compiled in ffmpeg libraries and if it is really my problem. Any ideas how to list all codecs used/provided by ffmpeg?
