• OSError : MoviePy error : the file guitar.mp4 could not be found

  9 septembre 2023, par dunnjm814

  I'm working on a video to audio converter with react and flask/python.
I have received a 500 with this error :

  


  raise IOError(("MoviePy error: the file %s could not be found!\n"
OSError: MoviePy error: the file guitar.mp4 could not be found!
Please check that you entered the correct path.


  


  EDIT : As stated in comments, moviepy VideoFileClip is looking for a path. Per suggestion, I am now attempting to write the incoming video file to a temp directory housed in the backend of the app. The updated stack trace shows the filepath printing, however when presented to VideoFileClip it is still unhappy.

  


  The following snippet is the onSubmit for the video file upload :

  


  const onSubmit = async (e) => {
    e.preventDefault()
    const data = new FormData()
    console.log('hopefully the mp4', videoData)
    data.append('mp3', videoData)
    console.log('hopefully a form object with mp4', data)
    const response = await fetch('/api/convert', {
      method: "POST",
      body: data
    })
    if (response.ok) {
      const converted = await response.json()
      setMp3(converted)
      console.log(mp3)
    } else {
      window.alert("something went wrong :(");
    }
  }


  


  Here is a link to an image depicting the console output of my file upload
from within init.py

  


  app = Flask(__name__)

app.config.from_object(Config)
app.register_blueprint(convert, url_prefix='/api/convert')

CORS(app)



  


  from within converter.py

  


  import os
from flask import Blueprint, jsonify, request
import imageio
from moviepy.editor import *


convert = Blueprint('convert', __name__)

@convert.route('', methods=['POST'])
def convert_mp4():
  if request.files['mp3'].filename:
    os.getcwd()
    filename = request.files['mp3'].filename
    print('hey its a file again', filename)
    safe_filename = secure_filename(filename)
    video_file = os.path.join("/temp/", safe_filename)
    print('hey its the file path', video_file)
    video_clip = VideoFileClip(video_file)
    print('hey its the VideoFileClip', video_clip)
    audio_clip = video_clip.audio
    audio_clip.write_audiofile(os.path.join("/temp/", f"{safe_filename}-converted.mp3"))

    video_clip.close()
    audio_clip.close()

    return jsonify(send_from_directory(os.path.join("/temp/", f"{safe_filename}-converted.mp3")))
  else:
    return {'error': 'something went wrong :('}




  


  In the stack trace below you can see file printing the name of the video, my only other thought on why this may not be working was because it was getting lost in the post request, however the fact it is printing after my if file: check is leaving me pretty confused.

  


  hey its a file again guitar.mp4
hey its the file path /temp/guitar.mp4

  Curious about any new requirements that the TV community may have for HTML5 video, I attended the W3C Web and TV Workshop in Hollywood last week. It’s already the third of its kind and was also the largest to date showing an increasing interest of the TV community to converge with the Web (...)

• How to pipe ffmpeg output to ImageMagick's convert tool ?

  30 décembre 2020, par Donny V.

  After a lot of searching I have come up with this to pipe a frame from ffmpeg to imagemagick's convert tool.

  


  ffmpeg -y -ss 00:02:01 -i ...\pano.mp4 -frames:v 1 -f png - | convert -sharpen 0x1 ...\pano_00_02_01.png


  


  I keep getting this error message.

  


  [NULL @ 000002e6cd1e00c0] Requested output format 'png' is not a suitable output format
pipe:: Invalid argument


  


  I have checked for png support using ffmpeg -format and its listed as png_pipe.

  


  I'm using ffmpeg version 4.3.1-2020-11-19-full_build
