• pyglet_ffmpeg loads and plays video in script(.py) but not loading(media load) in executable

  24 février 2020, par Mahesh Dilip Salvi

  i am playing full screen video in pyglet application which just plays video as follows, the script(.py) file loads mp4 video(as mediaload) and plays it well (windowed/fullscreen) but after making it executable with pyinstaller command (pyinstaller -w -F .\videoPlay.py) it is not loading media.
  *i identified it with ’try-except’ block with help of ctypes.MessageBox
  Please assist me by checking following thing.

  import pyglet, pyglet_ffmpeg
  
  
  
  pyglet_ffmpeg.load_ffmpeg()
  
  
  
  vidPath = 'm2Vid.mp4'
  
  
  
  window = pyglet.window.Window() #fullscreen=True
  
  player = pyglet.media.Player()
  
  source = pyglet.media.StreamingSource()
  
  MediaLoad = pyglet.media.load(vidPath)
  
  player.on_player_eos = window.close
  
  
  
  player.queue(MediaLoad)
  
  player.play()
  
  
  
  @window.event
  
  def on_draw():
  
      if player.source and player.source.video_format:
  
          player.get_texture().blit(0,0)
  
  
  
  pyglet.app.run()

• FFMPEG, player plays jerky video after encoding

  9 septembre 2020, par AKL

  I've been using FFMPEG on Windows 10 for a while. To help me do my job, I have got several DOS batch files which take parameters and perform tasks like cut from beginning, blur area, mute audio etc.

  


  I usually take big videos, extract the parts that I like using Avidemux, cut / apply filter on some parts using FFMPEG, join them using FFMPEG and then encode again to get rid of any errors (or jerkiness, etc) on my target player, which is Kodi 18.xx running on an Android TV (TCL brand).

  


  I have done a similar process for a video that I have been doing for several years and this video seems to be out of my control. I have chopped up the video using Avidemux 2.7.2. The video has been cut at key frames. If I take a single un-encoded file, it runs perfectly on my Android TV. If I encode it using FFMPEG, it starts to jerk when played on my Android TV.

  


  The videos always plays fine on VLC player running on my PC.

  


  Some information that may be helpful. I can attach detailed frame information if desired.

  Showing info for the source file. Codec is hevc, I think FFMPEG does not have default support for ?

  I would appreciate if someone can point to me where I am going wrong.

  


  The command used to perform the encoding is as follows (only the library was swapped between libx264 and lib265) :

  


  ffmpeg -i in.mp4 -map 0:v -c:v libx264 -video_track_timescale 24390 -crf 23 -map 0:a -c:a aac -copyts -vsync 0 -async 0 -movflags +faststart out.mp4


  


  P.S. My knowledge is more based on trial-and-error and I don't understand video formats (and concepts) much except for what got me to this point.

AK
