• Youtube-DL file download live progress

  7 février 2015, par roshkattu

  I am using the YoutubeDL library in a project. My environment is based on WINDOWS with XAMPP as the webserver boundle (apache,php,mysql,etc). I am using the youtube-dl.exe file to download the video and then use ffmpeg.exe to convert the video to an MP3 audio file.

  At the moment, I have an issue related to programming : I want to show live a progressbar while the video is downloaded with the youtube-dl.exe file. This exe creates a log file, that is updated while the video is downloaded. So my approach on this was to create a PHP file, that opens, parses the log file and get’s the progress percent, and sends it as a json encoded value to an AJAX function that is called every 100MS. Indeed, if the video is too large, there will be a very high ammount of data while polling the PHP file to get the progress state. And sometimes, the browser either crashes or freezes because of this ajax polling.

  My question is : is there any better approach to do this with PHP/AJAX ? Rathar than poll the file every 100MS, or 50MS ?

• 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

  


• How Can i Download this video ? Encrypted m3u8 ?

  16 septembre 2022, par אורן NO

  Hello everyone For almost a whole month now I have been trying to download a file from a specific site

  


  This is the link to the video
https://www.karaoke.co.il/api_play.php?type=clip&id=58370&autoplay=undefined&referer=karaoketv

  


  The M3u8 files are split into 2 parts.

  


  Video file
https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d...2-57d9518fae69

  


  And an audio file
https://www.video-cdn.com/video/encrypt/750802ea0bc2d02fac93adeaa1398ec2/750802ea0bc2d...2-57d9518fae69

  


  As far as I know there is a Key that needs to be entered in order to download the file.

  


  And when I run the command in ffmpeg

  


  I encounter many errors like :
Unable to open key file

  


  Anyone who can download it.
I would be very happy if he would write me a code that works and explain to me how to do it

  


  These are all the codes I have already tried
