Hi thanks a lot. I think that I will try to use the exact ffmpeg path (/usr/local/bin/ffmpeg) in order to launch it from my application. and ask people to install ffmpegx before using my .app
I'm not experienced enough to do it as you explained. But that's very good to know. dominik Ola Mogstad <[EMAIL PROTECTED]> a écrit : > Hi > > I would like to embed ffmpeg into a python stand alone application. does > somebody knows how to do that. i would like to call ffmpeg and mencoder using > shell commands from a python script (which is converted into executables- > .app). > I don't know how to ship ffmpeg within an application. > > dominik Hi, AFAIK, you have three ways to use ffmpeg in your application: 1) Require it to already be installed (use autoconf) 2) Link to it statically, i.e. the libav*.a files. This will dramatically increase the size of your executable. 3) Link to it dynamically, i.e. the libav*.so files. This will keep the size of your executable small but will require you to add the .so files to the distribution package. Furthermore, if you update your application at a later date, without changing the ffmpeg version, you won't have to redistribute as much. Personally, I prefer linking dynamically.
