  • Dynamic Watermarking Videos Strategy

    8 mai 2020, par Rakesh Guha

    I am running a video player that would play MPEG-DASH encoded video from an S3 bucket, I need to have it watermarked for each user when they play it. Can you suggest a non-removable watermarking method ?

    



      

    • So far I have tried


        

      • Css overlay (fairly easy and removable)

        • 


      • FFMPEG Transcoding (CPU consuming, would need a huge infra)

        • 


      • Video.js Dynamic watermarking plugin(looks okay, but not sure if removable or not)

        • 


      • 


    



    Suggestions would be very much appreciated

    


  • Create a subtitle mpd file with MP4box

    13 juillet 2020, par 123abc

    I'm creating a mpd file for a video player and for now I have everything to cover the video, audio and language settings but I'm struggling with the subtitles.

    


    Here's the command I used for audio and video :

    


    mp4box -dash 10000 -profile dashavc:264:onDemand -rap video/audio.mp4#audio/video


    


  • Subprocess call invalid argument or option not found

    14 septembre 2018, par NickB

    I’m trying to call ffmpeg command using subprocess.call() on linux, but I’m unable to get the arguments right. Before hand, I used os.system and it worked, but this method is not recommended.

    Using arguments with a dash such as "-i" gets me this error

    Unrecognized option 'i "rtsp://192.168.0.253:554/user=XXX&password=XXX&channel=0&stream=0.sdp?real_stream"'.
    
Error splitting the argument list: Option not found

    Using arguments without dash like "i" gets me this error

    [NULL @ 0x7680a8b0] Unable to find a suitable output format for 'i rtsp://192.168.0.253:554/user=admin&password=&channel=0&stream=0.sdp?real_stream'
    
i rtsp://192.168.0.253:554/user=XXX&password=XXX&channel=0&stream=0.sdp?real_stream: Invalid argument

    Here’s the code

    class IPCamera(Camera):
    
"""
    
    IP Camera implementation
    
"""
    
def __init__(self,
    
             path='\"rtsp://192.168.0.253:554/'
    
                  'user=XXX&password=XXX&channel=0&stream=0.sdp?real_stream\"'):
    

    
    """
    
        Constructor
    
    """
    
    self.path = path
    

    
def __ffmpeg(self, nb_frames=1, filename='capture%003.jpg'):
    
    """
    
    """
    

    
    ffm_input = "-i " + self.path
    
    ffm_rate = "-r 5"
    
    ffm_nb_frames = "-vframes " + str(nb_frames)
    
    ffm_filename = filename
    

    
    if platform.system() == 'Linux':
    
        ffm_path = 'ffmpeg'
    
        ffm_format = '-f v4l2'
    

    
    else:
    
        ffm_path = 'C:/Program Files/iSpy/ffmpeg.exe'
    
        ffm_format = '-f image2'
    

    
    command = [ffm_path, ffm_input, ffm_rate, ffm_format, ffm_nb_frames, ffm_filename]
    
    subprocess.call(command)
    

    
    print(command)

    BTW, I’m running this command on a MT7688.

    Thanks
