  • Should I open source my source code when I rebuild ffmpeg and dynamiclly link to my program ? [closed]

    20 septembre 2024, par openjz

    I have a c++ program developed on visual studio 2022, and my program need to work with ffmpeg, I rebuild it and I don't know if there is open source problem.

    


    I rebuild ffmpeg for windows msvc paltform (according to https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC) by customize the build configuration, but I don't modify the source code and build script of ffmpeg, and I don't enable gpl or gpl v3 in the build configuration, ffmpeg is dynamiclly linked to my program, I'm sure that the only license I should concern is the LGPL-2.1 or later, in this case, if I want to distribute my program for commercial use, should I open source my source code ?

    


  • How to build FFmpeg executable for commercial use using Windows ?

    18 octobre 2024, par Xel Naga

    I'm developing a commercial software and it requires ffmpeg.exe to run properly.

    



    I'm aware of the FFmpeg legal page (https://www.ffmpeg.org/legal.html) and want to Compile FFmpeg without "—enable-gpl" and without "—enable-nonfree". However the compilation guide (https://trac.ffmpeg.org/wiki/CompilationGuide) seems neglected because some links lead to 404 pages, and some required programs didn't install properly on my PC, crashed in fact.

    



    I tried all the ways to compile but could not succeed. I use Windows 8.1 and I'm not comfortable with minGW, MSYS, MSVC.

    



    How can I compile FFmpeg executable for commercial use, or better, how can I download ffmpeg.exe (compiled for commercial use) without hassle ?

    


  • FFmpeg framerate parameter

    24 avril 2020, par mentalmushroom

    I am confused by the FFmpeg framerate parameter. As far as I understand the docs and wiki, it sets the number of frames per second for the input (and the output unless -r option is specified). In fact, when I set the framerate to 1, the video is being played pretty much at its normal speed (25-30, but definitely not 1 frame per second as expected). Setting framerate to 2 makes it play around twice as fast (not 2 frames per second).

    



    To give a little bit more details, there is a python script which reads a video sample frame-by-frame as fast as it can and outputs these frames immediately to FFmpeg :

    



    python main.py -i myvideo.mp4 | ffmpeg -v warning -f rawvideo -pixel_format bgr24 -video_size 768x432 -framerate 2 -i - http://0.0.0.0:3004/fac.ffm


    



    What could be the reason for such behavior ?
