• How to handle FFMPEG module missing probe inside docker ?

  2 avril 2021, par DarkFantasy

  I am AWARE of how to solve this problem of missing problem module with spleeter on WINDOWS. Here is the solution
https://github.com/deezer/spleeter/issues/101

  


  How can I achieve the same inside my docker container ? In my docker file, the FFMPEG is being installed but it is missing the probe module. This is a common problem but one that I don't know how to solve inside of Docker.

  


  I tried doing

  


  RUN apt-get install -y ffmpeg
RUN pip uninstall ffmpeg-python
RUN pip install -r requirements.txt


  


  in my docker file but didn't work. The thing is, it was all working until last night. Today morning, I am getting this error when I rebuilt my docker image. Any help is appreciated.

  


• Why does this python ffmpeg module output h.264 instead of h.265 when downloading a video ?

  16 mars 2021, par pythondealer

  I'm trying to use this python module to download a video and transcode it to h.265

  


  For some reason whenever I run my script it outputs h.264, no matter which format I specify.

  


  Here is my code :

  


  import ffmpeg_streaming as ffmpeg

video = ffmpeg.input(vid_url)
stream = video.stream2file(ffmpeg.Formats.hevc())
stream.output('test.mp4')


  


  This should output 'test.mp4' encoded using h.265, however it is always h.264

  


  Any ideas how I can fix this ?

  


• How do I receive buffered files or streams from the fluent-ffmpeg module ?

  26 février 2021, par yahoo2344

  Logic was created to replace gif files with mp4 files. However, after saving the gif file to the server, the file is imported and converted to an mp4 file, the mp4 file is saved to the server and the file is read to return the buffer.

  


  Here's a question.

  


  


  1. When I recall files from the fmpeg module, can I receive them in a buffer or stream instead of a path ?

     


  


  2. Is there a way to receive the converted file as a buffer or stream without saving it ?

     


  


  


  return new Promise((resolve, reject) => {
        fs.writeFile(path.join(__dirname, `input.gif`), file, (err) => {
            if (err) {
                reject(null)
            }
            ffmpegg(path.join(__dirname, `input.gif`))
                .size(`500x500`)
                .format('mp4')
                .outputOptions([
                    '-movflags faststart',
                    '-pix_fmt yuv420p',
                    //'-vf scale=trunc(iw/2)*2:trunc(ih/2)*2'
                ]).on('end', () => {
                    fs.readFile(path.join(__dirname, `output.mp4`), (err, mp4Buffer) => {
                        fs.unlink(path.join(__dirname, `input.gif`), (e) => { if (e) console.log('error delete!') })
                        fs.unlink(path.join(__dirname, `output.mp4`), (e) => { if (e) console.log('error delete!') })
                        if (err) {
                            reject(null)
                        }
                        resolve(mp4Buffer)
                    });
                }).save(path.join(__dirname, `output.mp4`))
        });
    })
