• Missing ffmpeg in deployed application

  30 décembre 2017, par Dexstrum

  I have created a python GUI which utilizes ffmpy and tkinter. It works fine running in PyCharm and also in py2app’s alias mode. After I deployed it using py2app and ran the program, it loaded up, but nothing happened. After doing some digging, I found that the error was ’ffmpeg executable is missing.’

  I tried using pyinstaller to remedy the issue, but the application did not even run.

  The warning.txt output file gave me this :

  I am not sure where to go from here. I don’t know how to include ffmpeg into the deployed application, and when I include the modules in the setup.py file it throws me a different error. Is there a reason why the py2app is not deploying the application with ffmpeg ?

• How to compile FFProbe as stand-alone application ? (Mac/Linux/Win)

  16 janvier 2016, par Hanzaplastique

  I’m trying to compile FFMPEG (I’m actually only looking for FFProbe, which is included in the FFMPEG tools) as a standalone application for MacOS X, Linux and possibly Windows.
  With standalone I mean that the libraries (x264, OpenJPEG, etc) are "embedded" into the executable so that I have to distribute only one executable for FFProbe - I apologize that I don’t know the proper lingo for this (please let me know), I’m a newbie when it comes to this.

  I have started by trying to do this under MacOS X, without any luck, but plan to do this for Linux and MacOS X as well.

  I did see a few pre-compiled binaries that do this, and do not depend on extra libraries, but the versions I have found so far are either not the current version (1.x) or do not included the libraries in the executable (evermeet).

  I followed several guides (for example : FFMpeg MacOSX Compilation Guide, reneVolution), with or without the use of Brew, but none of these show me how to embed the libraries in the executable.
  I assume this is an option to be set for linking.

  I’m not sure if it’s appropriate to ask this question for Win, Mac and Linux at the same time - if it’s not appropriate : I’d like to start with doing this for the Mac version.

  My system runs MacOS X 10.9, XCode 5.0.2, with commandline tools and brew installed. I’m only looking for an Intel binary, so not a universal or PowerPC binary.

  For Windows I can use either Windows 8.1 or XP, for Linux I currently use Ubuntu 12, all of which are virtual machines.
