• How to prevent my users from installing ffmpeg themselves

  7 février 2018, par keys king

  I would like to develop a program for converting video formats based on the ffmpeg command line on mac. I should use c ++ or python. But now there is a problem that bothers me. I do not want my users to have to install the ffmpeg command themselves , before I use my program, so what should I do ? My question may be naive, I’m just a sophomore in college and I would be very grateful if you could help me.

  I should check whether there is ffmpeg in the program, and then use the command line to install it ? I hope my program can bring ffmpeg, rather than to install

  Sorry, I did not say clearly. I hope my program can be the same as the normal mac program can be placed directly into the Application folder. And then you can open directly. I will use qt to draw the interface

• Problems in making Video from Lottie JSON File and Overlay it with original video using FFMPEG

  26 juin 2019, par Krishna Vyas

  there is some unique concept about processing Lottie Animations using FFMPEG video processing library and MediaCodec. In that, I wants to make video from Lottie animation and overlay that video on other original video.

  But the problem is i’m unable to make a video with transparent background from Lottie animation. So i made simple video from Lottie animation using MediaCodec and MediaMuxer, it takes one by one frame from Lottie Drawable and attach it to the video(Lottie Video). Here is the link about this concept- https://engineering.21buttons.com/how-to-generate-videos-using-lottie-in-android-2db6ecceb2a

  And then i overlay this video to the original video using FFmpeg library. Here FFmpeg does two task, first it makes transparent background in Lottie Video and second it overlays this Lottie Video above the original video.

  And here the actual problem is out, FFmpeg takes more than 8 to 9 minutes in processing of video of 25 seconds, So i wants to get solution for this problem, as i have time limit of only 1 to 2 minutes. Any one has a solution for it or new ides for implementation of this concept, then please tell me i’ll appreciate it.
