• FFMPEG crash while cropping video

  18 octobre 2022, par Khawar Raza

  I am using FFMPEG to crop a video. I am using ffmpeg-kit as a ffmpeg wrapper in my android app where the user can select any output size irrespective of the original video aspect ratio. Below is the problematic command :

  


  -i "/storage/emulated/0/Download/83a2f6_1080p~2.mp4" -filter_complex "[0:v]crop=304:236:2:2[cropped]" -map "[cropped]" "/storage/emulated/0/DCIM/appname/vid_d8ee328d-ec7a-468b-9313-4561dceea33e.mp4"


  


  When the execution starts, the application crashes.

  I don't know what is wrong with the output width and height parameters. If I change [0:v]crop=304:236:2:2[cropped] to [0:v]crop=304:304:2:2[cropped] with change in height, the process completes successfully. The original video (1080x808) is not smaller than the output size. It does not seem to be a problem in the video as I have tried different videos. Any tips on what is missing from my command ?

  


• ffmpeg command for overlaying a video onto am image with blend

  6 décembre 2022, par tebowner

  I have these requirements but cant seem to get this even close :

  


  

  • ffmpeg to produce a mp4 video

  


  • inputs : an image of varying size, an audio wav of X length, a video for the overlay such as particles or dust

  


  • create an mp4 with the image as the final video size, the overlay video light blended into the image using zoom/crop (no stretching of size), length of video is size of audio

  


  • assume the video overlay is bigger than the image as far as height and width
