• Where can I find high-quality videos for testing video processing ?

  15 novembre 2018, par Workman

  Aside from Big Buck Bunny, Sintel, and Elephant’s Dream, what are other high-quality and free sources for high quality video ?

  I’m using these videos internally to test video transcoding options and am not public redistributing. Any suggestions for content that falls under this category ?

• Heroku can't find ffmpeg install included in NodeJS app

  5 août 2020, par Literally

  I'm trying to run a ffmpeg command with the ffmpeg node package and it's working fine locally, giving me exit code 0 + the file, but when I publish the same code to Heroku it gives me error code 127 and does nothing.
This is the code I'm running, what could be wrong ? The files/ and ffmpeg/ directory is in the project root, but only files/ gets found on Heroku while both gets found locally.

  


  var ffmpeg = require('ffmpeg');
var spawn = require("child_process").spawn;
var pathToFfmpeg = ".\\ffmpeg\\bin\\ffmpeg"

var ffmpeg = spawn(pathToFfmpeg,
        `-i ./files/noaudio.mp4 -i ./files/music.mp3 -c:v copy -c:a aac ./editedfiles/output.mp4`.split(" "),
        { shell: true })

    ffmpeg.on('exit', (code, signal) => {
        console.log("ffmpeg shutdown: code " + code + ", signal " + signal)
    })

  4 juillet 2023, par nicospbr5

  I am desperately trying to cut an MP4 video with ffmpeg, following this [example] https://github.com/facebookresearch/VideoPose3D/blob/master/INFERENCE.md

  



  ffmpeg -i P1060513copy.mp4 -ss 3:12 -to 3:30 -c copy output.mp4


  



  I am getting this error

  To avoid this error I converted the file in mkv and cut it (works perfectly) and then I wanted to convert it back to MP4 but ended with the same error.

  



  Can anyone help me ?

  



  Thank you
