  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  protected void onCreate(Bundle savedInstanceState) {
    
    super.onCreate(savedInstanceState);
    
    setContentView(R.layout.activity_main);
    

    
    new FFmpegFrameRecorder("", 320, 240, 1);
    
  }
    
}

    this is my log error :

  • Hide ffmpeg's console window when running YoutubeDL in GUI application

    23 juin 2016, par Slayther

    I’m developing a basic application which can download YouTube videos. Throughout the development, I had several quirks, including issues with formats.

    I decided to use a hopefully foolproof format syntax that youtube-dl will happily download for me in almost any case.

    Part of my YoutubeDL options look like this :

    self.ydl_opts = {
    
    'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
    
    'quiet': True,
    
    'progress_hooks': [self.ydl_progress],
    
    'outtmpl': None
    
}

    The outtmpl is inserted later on when output folder is chosen by the user.

    Since I’m using this format string, youtube-dl uses ffmpeg to merge(?) the audio and video if they are downloaded separately.

    When it does that, it opens very annoying console windows that capture the focus and interrupt other things I might be doing while the videos are downloading.

    My question is, how can I prevent ffmpeg or youtube-dl from creating those console windows from appearing, aka. how can I hide them ?

    EDIT :

    I’ll provide bare bones script that reproduces the problem :

    from __future__ import unicode_literals
    
from PyQt4 import QtGui, QtCore
    
import youtube_dl, sys
    

    
def on_progress(info):
    
    print info.get("_percent_str", "Finished")
    

    
ydl_opts = {
    
    'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
    
    'progress_hooks': [on_progress],
    
    'quiet': True,
    
    'outtmpl': "C:/Users/Raketa/Desktop/%(title)s.%(ext)s"
    
}
    

    
ydl = youtube_dl.YoutubeDL(ydl_opts)
    

    
class DownloadThread(QtCore.QThread):
    
    def __init__(self):
    
        super(DownloadThread, self).__init__()
    
        self.start()
    

    
    def __del__(self):
    
        self.wait()
    

    
    def run(self):
    
        print "Download start"
    
        ydl.download(["https://www.youtube.com/watch?v=uy7BiiOI_No"])
    
        print "Download end"
    

    
class Application(QtGui.QMainWindow):
    
    def __init__(self):
    
        super(Application, self).__init__()
    
        self.dl_thread = DownloadThread()
    

    
    def run(self):
    
        self.show()
    

    
def main():
    
    master = QtGui.QApplication(sys.argv)
    

    
    app = Application()
    
    app.run()
    

    
    sys.exit(master.exec_())
    

    
if __name__ == '__main__':
    
    main()

    2(?) consoles appear at start of each download and 1 longer lasting console appears when both video and audio are downloaded. When downloading longer videos, the last console becomes unbearable.

    Is it possible to get rid of those ?

  • Encode mjpeg files from within an iOS app

    9 mai 2017, par Ricardo Sanchez-Saez

    I’m trying to encode a video file with the mjpeg codec on iOS. Basically, I’m trying to replicate what this command does

    ffmpeg -i recording.mp4 -vsync vfr -q:v 9 recording.mjpeg

    from within an app.

    Is there an easy way to do this ?

    I’m looking at using the low level ffmpeg API to do this like in this example, but I was wondering if somebody knows of a simpler way.

    I have also access to the individual video frames in CMSampleBufferRef format, in case that makes it easier. AVAssetWriter doesn’t seem to support mjpeg, which is unfortunate, as that would make things super simple.
