  • How do I use ffmpeg to bulk scale videos of different sizes to the same size (some potentially with black bar padding) ?

    9 décembre 2020, par Tumbleweed53

    I have a bunch of videos I want to stitch together. I want to scale them all to the same size, maintaining aspect ratio (thus adding black bar padding if necessary). Some videos will be downscaled, but most upscaled.

    


    Does anyone have a clever ffmpeg scale formula to accomplish this ? My alternative is to iterate through every video and calculate the scale formula based on its size, but I'd prefer not to do that if I don't have to.

    


  • ffmpeg Merge audio into mp4 video

    21 juillet 2022, par LQH Gaming

    For example :
I have an audio file 5 minutes long
And 1 mp4 no audio file is 10 minutes long
I want to use ffmpeg to stitch them together and output a 5 minute mp4 video ( equal to the length of the input audio file )
Thank you

    


  • Randomly extract video frames from multiple files

    23 avril 2022, par PatraoPedro

    Basically I have a folder with hundreds of video files(*.avi) each one with more or less an hour long. What I would like to achieve is a piece of code that could go through each one of those videos and randomly select two or three frames from each file and then stitch it back together or in alternative save the frames in a folder as jpegs.
Initially I thought I could do this using R but quickly I've realised that I would need something else possible working together with R.

    



    Is it possible to call FFMPEG from R to do the task above ?

    



    I've trawled the internet looking for things that could help me start but most of what I've found is too specific and really applicable to what I need to do.

    



    Could anyone please help me out or simply point me in the right direction.

    



    Many thanks
