• ffmpeg motions not working properly while using multiple urls

  22 avril 2021, par al pacino

  I am trying to apply ffmpeg transitions but sometimes video gets concatenated without any transition. In the command below I have used input 1 which in present on derectory and second input is online video url. the output video got concatenated without distance transition -

  


  one example of distance transition command is below-

  


  ffmpeg -i video1.webm -i 'url2' -filter_complex '[0]scale=1280:720,settb=AVTB[v0];[1]scale=1280:720,settb=AVTB[v1];[v0][v1]xfade=transition=distance:duration=1:offset=9,format=yuv420p’ output_video.webm


  


  and log is below-

• 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
