  swresample/resample : Limit filter length
  Related to CID1197063
  The limit choosen is arbitrary and much larger than what makes sense.
  
  It avoids the need for checking arithmetic operations with the length for overflow

• Merge video and audio using ffmpeg and download immediately in django

  29 janvier 2024, par Suresh Chand

  I have video and audio file which is to be merge and download immediately. I have written some code but it will start download after merged. I want when user hit the url, then it will start merging and downloading immediately so that user don't have to wait for it.

  


  video_url = "./video.mp4"
audio_url = "./audio.mp4"

output_filepath = './merged.mp4'

try:
    process = subprocess.Popen([
        "ffmpeg",
        "-i", video_url,
        "-i", audio_url,
        "-c:v", "copy",
        "-c:a", "copy",
        "-f", "mp4",
        "-movflags", "frag_keyframe+empty_moov",
        "pipe:1"
    ], stdout=subprocess.PIPE)

    def generate_stream():
        while True:
            data = process.stdout.read(1024)
            if not data:
                break
            yield data

    response = StreamingHttpResponse(generate_stream(), content_type="video/mp4")
    response['Content-Disposition'] = 'attachment; filename="stream.mp4"'
    return response

except subprocess.CalledProcessError as e:
    return HttpResponse("Error: {}".format(e), status=500)


  


  But it will merge and then start downloading. I want to be at same time so that user don't have to wait until the merging process.

  


  I am using django and i am learning django
