    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Save video clip from longer video between two timestamps in Python cv2

    14 juin 2022, par Elizabeth Orrico

    I have an hour-long video that I would like to save a clip between two timestamps— say, 11:20-11:35. Is the best way to do this frame-by-frame, or is there a better way ?

    


  • FFmpeg does not save the mp4 clips to file

    31 janvier 2021, par oo92

    I'm using the FFmpeg Python library to save 60-second mp4 clips to a .mp4 file from Twitch live streams using its API. This is my code :

    


    current_dir = os.getcwd()

client = TwitchClient(client_id='')
streams_now = client.streams.get_live_streams(limit=100, offset=900)
epoch = str(math.ceil(time.time()))

if not os.path.exists(current_dir + '/twitch_videos/'):
    os.mkdir(current_dir + '/twitch_videos/')

for i in range(0, 100):
    try:
        username = streams_now[i]['channel']['name']
        id = streams_now[i]['id']
        game = streams_now[i]['game']
        game = game.translate(str.maketrans({':': '-', ' ': '-', "'": '', '!': '', '&': '_', '.': '', '+': '_'}))
        streaming = streamlink.streams('http://twitch.tv/' + username)
        stream = streaming["best"].url

        twitch_stream = ffmpeg.input(stream)

        twitch_stream = ffmpeg.filter(twitch_stream,
                                      'fps',
                                      fps=1,
                                      round='up')

        twitch_stream = ffmpeg.output(twitch_stream,
                                      current_dir + '/twitch_videos/' + '%d_' + username + '_' + epoch + '.mp4',
                                      sc_threshold='0',
                                      g='60',
                                      f='segment',
                                      segment_time='600',
                                      segment_format_options='movflags=+faststart',
                                      reset_timestamps='1')frl3dqgn21bbpp6tajjvg5pdevczac
        ffmpeg.run(twitch_stream)


    except:
        pass


    


    I am concatenating the path it should go to the name of the file but the folder is empty after I take a look. The reason why its in the try-catch block is because some streams do not have the best tag so I want to skip those.

    


    Update

    


    I put a bunch of print statements inside the try block and none of them get printed. I put similar if statements inside the except block and they are all printed. This means that there is something wrong with my code inside the try block. This tells me that the code inside the try block never gets executed.
