  Hi I’m working on a project which needs to create animations by playing 2000 charts in 50 fps using FFMPEG, the command is :

  ffmpeg -y -framerate 50 -i img-%04d.png -vb 40M -vcodec h264 esez.mp4

  charts are located in the same folder with name as img-0001.png img-2000.png

  It worked well on my Mac. On Windows, the command can run and generate a mp4 file. But the animation is just black screen on Windows media player. I also tried open with VLC, it has some image, but not proper at all.

• FFMPEG - Not finding codec parameters

  9 septembre 2024, par Tanner Smith

  I'm trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video : mjpeg). A Google search did not bring much up that was useful.

  The images reside in the /tmp directory with names such as img001.jpg and img002.jpg.

  



  Any ideas ?

  



  Thanks
