• format dav not convert [closed]

  5 décembre 2020, par Raphael Figueiredo

  I have this file that comes from of an unknown brand, however when I use the code that I am used to normally use in other models it does not work, appears format dav detected only with low score of 1 misdetection possible.
I use the following code :

  


  forfiles / s / M * .dav / C "cmd / c ffmpeg -i @file -vf setpts = 2.0 * PTS @ fname.avi -n"

• How to get FFmpeg/sox working on heroku flask app ?

  6 mars 2019, par Arjun Akkiraju

  I am trying to convert an mp3 audio file from .mp3 format and multi-channel audio to a .flac format and single-channel audio in my python flask app. I am currently using the python wrapper for ffmpeg called ffmpy. Here is my code.

  from ffmpy import FFmpeg
  
  ff = FFmpeg(
  
          #executable = '/ffmpeg-20190304-db33283-macos64-static/bin/ffmpeg',
  
          inputs = {<input />: None},
  
          outputs = {'<output>': ['-ac 1']}
  
     )
  
     ff.run()</output>

  We have faced quite a few errors with this code segment when deploying the flask app to heroku (The code seems to work fine locally). The error I am running into is a ffmpy.FFExecutableNotFoundError: Executable 'ffmpeg' not found execption. To fix this, I tried downloading the ffmpeg build and set that as my executable (see the comment in my code above). I dragged that into my project directory and added the code above but the same error was throwing, except it said : ffmpy.FFExecutableNotFoundError: Executable 'ffmpeg-20190304-db33283-macos64-static/bin/ffmpeg not found. The name of the file was the executable not found in case that was unclear. We then tried adding buildpackages from the following two github repos : https://github.com/HYPERHYPER/heroku-buildpack-ffmpeg and https://github.com/integricho/heroku-buildpack-python-ffmpeg but neither buildpack solved the issue. When we ran heroku run bash and typed ffmpeg we got a command not found error. I then tried to install it with apt-get install ffmpeg on the heroku bash but that also failed. This is my requirements.txt file.

  ` We also tried to run a subprocess with the command sox :

  import subprocess
  
  
  
  subprocess.call(['sox', , '-r', '44100', '

  This kept saying sox: not found and thus I pivoted to ffmpeg. If there is a more efficient way to do this conversion please let me know as I’m new to both python and heroku. Any help is appreciated.

• FFMPEG in worker role

  I am trying to create worker role solution where it reads the content from the blob and use the FFMPEG and convert the video files on from MP4 to AVI. whenever i deploy the worker role solution in the cloud the VM changes, then how to setup a FFMPEG on the machine where i am going to deploy and the command through cmd ?
