• ffmpeg issue with file paths and wav file [closed]

  8 September 2023, by 101is5

  I'm trying to run:

  


  ffmpeg -i audio_input_files/voz.wav voz.mp3


  


  I'm using Windows 11 and I've tested it in PowerShell and CMD.

  


  The issue here involves path syntax and file format.
  
As shown in an example from ffmpeg docs (ffmpeg -i /tmp/test%d.Y /tmp/out.mpg) and many other sources, I should put a leading slash in relative paths. Here, however, that causes No such file or directory, for both slash and backslash. Unlike everywhere I've looked, removing the leading slash was the solution.

  


  Now, if the input is provided as a path and it is a .wav file, I get Invalid data found when processing input.

  


  Providing just names (and being in the correct folder, obviously), e.g. ffmpeg -i voz.wav voz.mp3 works just fine, though.

  


  Is there a workaround for that, i.e. in case I want to use paths for wav files with ffmpeg?

  


• How can I take a user input in python3 and use it for the file name of ffmpeg-python file output?

  25 November 2022, by tylerdurden4285

  I am trying to do something like this:

  


  import ffmpeg

user_input =input("give your output file a name: ")

(
    ffmpeg
    .input('input.mp4')
    .vflip()
    .output('(user_input).mp4')
    .run()
)



  


  I am wondering how I can take the string input from the user and make it the filename. So if they input "tester" the resulting output file would be "tester.mp4".

  


  I am running it on an ubuntu 20.04 WSL. I'm new to here and doing my best to learn python3 and ffmpeg so please be gentle with me if I broke any community rules. I'll improve as I go.

  


  I don't know what to search for to find the answer to this problem.

  


• check if file is downloaded in temp in GCF from GCS

  3 September 2020, by soshi

  Im making video encoder using GCF

  


  that downloads video file from gcs to /tmp and encode it by ffmpeg.

  


  I want to ask how to check if file is downloaded in tmp?

  


  I tried console.log(process.cwd()) but tmp folder is not displayed

  


  exports.encodeVideo = async (req, res) => {

 mkdirp('/tmp')

 storage.bucket('video-bucket').file('raw/samplevideo.mp4').download({ 
 destination:'encoded/samplevideo.mp4' })

ffmpeg........
}
