• How to get the video count of youtube_dl (1 of 256) in its output and hide ffmpeg console when converting the format ?

  28 août 2020, par Kristen

  I am creating a GUI program in Qt creator via Pyside2 and it's a program that lets you download Youtube music. My goal is to get the video count like x of 256 or x of 2 or 1 of 256 when downloading the playlist but I don't know how. I've come across two problems.

  


  First problem : I don't know how to get this information from youtube_dl output

  


  [youtube:playlist] Downloading playlist PLi0XaxnSihZSnD1TNm82Y43o92r6UNEfH - add --no-playlist to just download video -5EmnQp3V48

14:03:36: C:\Python38\python.exe exited with code 0


  


  Second problem : If my program is in .exe format then FFMPEG console appears and disappears immediately after it has completed the conversion but it's taking the user focus every time which gets annoying.

  


  What I've tried for first problem is that I tried to get it manually but it did not work then I checked youtube_dl github download dictionary keys and there is not a key that can acquire that video count 1 of 256

  


  print("Download keys:", download.keys())
Download keys: dict_keys(['status', 'downloaded_bytes', 'total_bytes', 'tmpfilename', 'filename', 'eta', 'speed', 'elapsed', '_eta_str', '_percent_str', '_speed_str', '_total_bytes_str'])


  


  What I've tried for second problem is actually none. I checked C# versions and with C# you can hide that console or disable it but I haven't found a way to do that in Python yet. Goal here is disable ffmpeg console taking either the focus or hide/disable it or third option is to use another converter.

  


  Youtube_dl code that is in Worker thread :

  


  def run(self):
    self.main_window.progressBar.setValue(0)

    self.ydl_opts = {
        'format': 'bestaudio/best',
        'noplaylist': self.main_window.playlist,
        'source_address': '0.0.0.0',
        'ignoreerrors': True,
        'progress_hooks': [self.my_hook],
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3'
        }]
    }

    with youtube_dl.YoutubeDL(self.ydl_opts) as ydl:
        ydl.download([f'{self.main_window.downloadURL.text()}'])

def my_hook(self, download):
    if download["status"] == "finished":
        print("Finished")
        self.main_window.progressText.setText("Ready")
    if download["status"] == "downloading":
        self.updateText.emit("Downloading...")
        percent = download["_percent_str"]
        percent = percent.replace("%", "")
        self.updateProgress.emit(float(percent))


  


  Edit : FFMPEG console appearing and disappearing for a moment is shown in this video here in dropbox :

• Overlay image zoom out and move

  5 avril 2021, par Pier Giorgio Misley

  I have a video with an image overlay. The picture is set nearly full screen for the first 10 seconds, and aftwerwards I need to zoom out the image to a smaller size and place it in the bottom left corner for the rest of the video.

  


  At the moment I split the input image and overlay it twict to the video, without transitions, one for the "big" picture and one for the "small" picture and it works fine.
What I would like to make is a "zoom out and moove" effect to make it smoother from the big central picture to the small one.

  


  This is my current complex filter :

  


  -i "video.mp4" 
-i "img.jpg" 
-filter_complex "[1:v]split=2[img10][img20];[img10]scale=1469:856[img11];[img20]scale=293:171[img21];[0:v][img11]overlay=(main_w-overlay_w)/2:(main_h - overlay_h)/2:enable='between(t,0,10)',fade=out:st=9:d=1:alpha=1[vid];[vid][img21]overlay=10:(main_h-overlay_h-40):enable='gte(t,10)'" 
-crf 18 -c:a copy "out.mp4"


  


  How can I make it as a single image overlay with zoom out + move effect ?

  


• Evolution #4380 (Nouveau) : gif animé searching.gif

  16 septembre 2019, par jluc -

  L’image searching.gif (https://core.spip.net/projects/spip/repository/changes/spip/prive/themes/spip/images/searching.gif , qu’on voit là : http://contrib.spip.net/prive/themes/spip/images/searching.gif ) apparaît notamment sur la barre de titre rose tyrien du message central lors d’une mise à jour de SPIP, et elle est assez moche : mal centrée dans la barre de titre, c’est un peu un pâté de pixel... comme un vieux gif animé.

  Peut être y aurait le moyen d’une animation plus moderne, en svg éventuellement ?
