• HLS from node to iOS app

  16 novembre 2016, par Carol

  I created a API in node that you can upload a video (.mp4, .avi, etc). Then, the video is request by a iOS app in swift.

  I would like to use HTTP Live streaming from the app. Can you help me how can I transform the video file to chunks .ts and generate the playlist file (m3u8) to be consumed by the app ?

  This is the correct flow ?
  What it’s the best solution ?

  Thanks !

• ffmpeg - how to add text on black background at end of video for 10 sec ?

  3 octobre 2015, par jamie

  I have some mp4 files I’d like to add some white text reading something like

  "StackOver Flow Rules see more at www.stack.com/324324 bla bla and some more words here !"

  To the end of the videos on a black background that last 10 seconds.

  How would I achieve this with FFMPEG ?

• Kivy does not load ff_mpeg

  25 mai 2016, par Edv Beq

  I have been trying to use a simple code to play videos with Kivy and Python. The shortest code I found is the one shown below.

  1. At first, Kivy was showing an error on Pyglet and ff_mpeg. Therefore, I installed Pyglet - which consequently require AVbin, - none of which would load automatically.

  2. I found the following solution on another post - which fixed the sound :

     import pyglet
     
     pyglet.lib.load_library('avbin')
     
     pyglet.have_avbin=True

  3. Can I do the same with ff_mpeg ? Can it be loaded manually ?

  4. I have already installed ffmpeg :

     • When I type ffmpeg -version on cmd - it displays ffmpeg version N-.... built with gcc 4.9.2(GCC). Also, I have added all the paths in WIndows.

  5. Also my pip list :

     Cython (0.21.2)
     
     docutils (0.12)
     
     ffmpegwrapper (0.1.dev0)
     
     Kivy (1.8.0)
     
     Kivy-Garden (0.1.1)
     
     Pillow (2.1.0)
     
     pip (6.0.8)
     
     pygame (1.9.2a0)
     
     pyglet (1.2.1)
     
     requests (2.5.1)
     
     setuptools (12.0.5)

  6. Error on Kivy :

     [DEBUG      ] [Video     ] Ignored <ffmpeg> (import error)
     
     [INFO       ] [Video     ] Provider: pyglet(['video_ffmpeg'] ignored)
     
     </ffmpeg>

     and

     File "C:\Python33\lib\site-packages\kivy\core\video\video_pyglet.py", line   67, in _update
     
        self._player.dispatch_events(dt)
     
     AttributeError: 'Player' object has no attribute 'dispatch_events'

  7. And, finally here is the code - I am working with :

     import kivy
     
     import pyglet
     
     pyglet.lib.load_library('avbin')
     
     pyglet.have_avbin=True
     
     
     
     kivy.require('1.8.0')
     
     
     
     from sys import argv
     
     from os.path import dirname, join
     
     from kivy.app import App
     
     from kivy.uix.videoplayer import VideoPlayer
     
     
     
     class VideoPlayerApp(App):
     
     
     
         def build(self):
     
             if len(argv) > 1:
     
                 filename = argv[1]
     
             else:
     
                 curdir = dirname(__file__)
     
                 filename = join(curdir, 'project.mp4')
     
             return VideoPlayer(source=filename, state='play')
     
     
     
     if __name__ == '__main__':
     
         VideoPlayerApp().run()

  I have searched a lot of other threads, and installed ffmpeg several times with no luck. Any help would be greatly appreciated. Thank you !
