• youtube-dl sometime hangs with "[ffmpeg] Correcting container"

  I have a bash script that attemts to download a youtube video. The output is below. The problem is that sometimes it works perfectly (completes quickly).
  But most of the time it hangs on "Correcting container....". Does anyone know why ?

• youtube-dl - How do I ensure that the "original" video formats are downloaded ?

  25 juin 2018, par Schytheron

  I am building a C# GUI (Windows only) for youtube-dl where I allow the user to pick the desired video quality and framerate but I am having problems with format selection. youtube-dl sometimes downloads either the wrong video file or the wrong audio file (often it is audio) and after merging them I end up with a .mkv file because according to FFmpeg the files I am trying to merge are incompatible.

  These are the format selection queries I have tried to far :

  bestvideo[height<=?%height%][fps<=?%fps%]+bestaudio/best

  and

  public string[] qualities = { "4320", "2160", "1440", "1080", "720", "480", "360", "240", "144" };
  
  public string[] framerates = { "60", "50", "48", "30", "24" };
  
  private void buildFormat(int qualSkip,int fpsSkip)
  
          {
  
              string[] qualitiesMin = qualities.Skip(qualSkip).ToArray();
  
              string[] frameratesMin = framerates.Skip(fpsSkip).ToArray();
  
              format = "-f ";
  
              foreach (string quality in qualitiesMin)
  
              {
  
                  foreach (string framerate in frameratesMin)
  
                  {
  
                      format += "bestvideo[height=?" + quality + "][fps=?" + framerate + "]+bestaudio/";
  
                  }
  
              }
  
              format += "best";
  
          }

  In the first one I had a problem where on some videos youtube-dl downloaded a video in a lower framerate than what I requested (for example, if I request 1080p60FPS I get 1080p30FPS). I tried to fix this in the second method by searching for the best video for all qualities and framerates that are equal to or lower than the one I picked (for example, if I pick 1080p60FPS it would look for videos from 1080p60->1080p30->720p60->720p30->...->144p30).

  The second method however looks overly convoluted and stupid and another problem still remains. youtube-dl always picks the best audio quality no matter what video quality I choose. I want the audio quality to scale with the video quality (for example, if I pick 144p I want poor audio quality). There has got to be a better way.

  Maybe I am explaining this poorly but I basically want youtube-dl to ALWAYS (consistently) download the exact same video and audio format as the one that is displayed in the youtube video player itself for each picked video quality (see image below). How do I do that ?

  Example 1, Video and audio format codes of video in 4K (the numbers in the red circles are the format codes) :
  

  Example 2, Video and audio format of same video but this time in 720p :
  

  (should also pick a lower framerate video of same quality if that framerate is not available in the YouTube quality selector, for example 1080p30FPS in a 1080p60FPS video)

  Thanks !

  I am using writemind’s ffmpeg module (running ffmpeg v3.0.2)
  http://writingminds.github.io/ffmpeg-android-java/

  But I am getting the follow error when executing the command

  [NULL @ 0xe93aa000] Unable to find a suitable output format for ’ -i

  The command is supposed to mix the audio of a video file with the audio of another audio file to produce a new video file.
