• 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 :

• Unable to parse option value xxx.srt as image size in ffmpeg

  28 mars 2022, par showkey

  I had already set environment variable for the ffmpeg in my windows,want to embed the srt file into my mp4 file with ffmpeg :

  


  ffmpeg -i f:\sample\dance.mp4 -vf subtitles='f:\sample\dance.srt'  f:\sample\out.mp4


  


  It encounter a strange error :

  


  Press [q] to stop, [?] for help
[subtitles @ 0000000002c2fd00] Unable to parse option value "sampledance.srt" as
 image size
    Last message repeated 1 times

gs 'f:\sample\dance.srt'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument

  I copy the files dance.mp4 and dance.srt into f:\ffmpeg\bin,then do the following :

  


  cd  \d  f:\ffmpeg\bin
ffmpeg -i dance.mp4 -vf subtitles=dance.srt   out.mp4


  


  It works fine, how can make ffmpeg parse the option value f:\sample\dance.srt properly,make the command execute normally in my windows ?

  


  ffmpeg -i f:\sample\dance.mp4 -vf subtitles='f:\sample\dance.srt'  f:\sample\out.mp4


  


  @kesh,it is no use to write as below :

  


  ffmpeg -i f:\sample\dance.mp4 -vf "subtitles='f:\sample\dance.srt'"  f:\sample\out.mp4


  


• Jellyfin ffmpeg permission denied

  11 septembre 2022, par Steve

  I am running Jellyfin on a Raspberry Pi 4 in a docker container (https://hub.docker.com/r/linuxserver/jellyfin) and am trying to set up hardware accelerated video transcoding. I'm fairly certain I have set up the video devices & permissions correctly, but I am getting the following exception in the logs when trying to play a video through the web interface :

  The real head-scratcher is that if I log in to the docker container with docker exec -it  /bin/bash and paste the ffmpeg command from the logs and run it, it works fine.

  


  I'm running as the jellyfin user, which is in the video group, and has read/write access to the media directory.

  


  Any thoughts ?

  


  My docker-compose file is attached below, if any other system information is needed let me know.
