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.

Here are the two outputs, from a good run (with a local > file) and an problem run pulling the file from a web server (The file is I just went back and tried this with ffmpeg itself, both a version that I've built and a recently downloaded binary. Both showed the same kinds of issue. The issue is with pulling an .flv file using http. I'm going to post this to the more general list. Here's an example output...
