• Can i ship a commercial product with opencv_ffmpeg.dll, or is that a breach of the license ? [closed]

  6 juin 2020, par anti

  We are developing an application that uses opencv to load video files. This will be commercially available.

  



  In the current (as yet unreleased) version, I have added the opencv_ffmpeg410_64.dll file to the application build directory, as it is needed to load video files.

  



  However, reading online, I cannot track down a clear idea of whether or not I can legally ship with this dll.

  



  A question on opencv answers says yes :

  



  https://answers.opencv.org/question/28202/opencv_ffmpegdll-license/

  



  But another says not :

  



  https://answers.opencv.org/question/128342/is-using-opencv_ffmpegdll-in-commercial-applicatoin-require-license/

  



  The FFmpeg license page seems to focus on using the source code, and i cannot get a clear idea of the situation when using only the single dll bundled with opencv.

  



  Can i legally ship an application with the opencv FFmpeg dll file ? Or should I use another video backend ?

  


• Animated line chart with pandas, matplotlib and ffmpeg

  10 avril 2020, par Mark K

  In producing an animated line chart, I have below data and codes.

  



  But when the chart produced, it shows no line. What did I do wrong ?

  



  Thank you.
