• Converting large number of MP3 files to videos for YouTube, each using same JPG

  2 juin 2020, par David

  Looking for a way to convert large number of mp3 files to videos each using the same image. Efficient processing time is important.

  



  Tried following :

  



  ffmpeg -i image.jpg -i audio.mp3 -vcodec libx264 video.mp4


  



  VLC played the resulting video file with the correct sound, but blank screen.
Microsoft Media Player played the sound and showed the intended image.
Uploaded the video to YouTube and received mesage "The video has failed to process. Please make sure you are uploading a supported file type."

  



  Would appreciate advice on how to make this work.

  I'm trying to implement capturing the camera screen using opencv and transmitting this frame to the YouTube streaming broadcast via ffmpeg. YouTube streaming does start when I run this code. However, it appears to be a black screen, not a camera screen. I don't see what the problem is.

  


  I didn't even start streaming at first, but I changed the command option to various things, and when I ran the code, I succeeded in starting streaming. There are many references to transmitting mp4, but there are not many references to transmitting real-time capture. I'm going to process the camera screen using opencv and then send it to streaming. I don't know what the problem is. Please help me.
