  • How to get a online video's duration without downloading the full video ?

    16 février 2018, par David Zhuang

    To get a video’s duration and resolution, I’ve got this function :

    def getvideosize(url, verbose=False):
    
try:
    
    if url.startswith('http:') or url.startswith('https:'):
    
        ffprobe_command = ['ffprobe', '-icy', '0', '-loglevel', 'repeat+warning' if verbose else 'repeat+error', '-print_format', 'json', '-select_streams', 'v', '-show_streams', '-timeout', '60000000', '-user-agent', BILIGRAB_UA, url]
    
    else:
    
        ffprobe_command = ['ffprobe', '-loglevel', 'repeat+warning' if verbose else 'repeat+error', '-print_format', 'json', '-select_streams', 'v', '-show_streams', url]
    
    logcommand(ffprobe_command)
    
    ffprobe_process = subprocess.Popen(ffprobe_command, stdout=subprocess.PIPE)
    
    try:
    
        ffprobe_output = json.loads(ffprobe_process.communicate()[0].decode('utf-8', 'replace'))
    
    except KeyboardInterrupt:
    
        logging.warning('Cancelling getting video size, press Ctrl-C again to terminate.')
    
        ffprobe_process.terminate()
    
        return 0, 0
    
    width, height, widthxheight, duration = 0, 0, 0, 0
    
    for stream in dict.get(ffprobe_output, 'streams') or []:
    
        if dict.get(stream, 'duration') > duration:
    
            duration = dict.get(stream, 'duration')
    
        if dict.get(stream, 'width')*dict.get(stream, 'height') > widthxheight:
    
            width, height = dict.get(stream, 'width'), dict.get(stream, 'height')
    
    if duration == 0:
    
        duration = 1800
    
    return [[int(width), int(height)], int(float(duration))+1]
    
except Exception as e:
    
    logorraise(e)
    
    return [[0, 0], 0]

    But some online videos comes without duration tag. Can we do something to get its duration ?

    avformat/dashenc : write a capture time Producer Reference Time element when none is provided by the encoder

    This way, the element will be present in any scenario when the write_prft option is used.
