• FFMPEG error with Python Popen on Windows 10

  5 juin 2019, par user9970503

  I’m trying to extract key-frames from a video called "twws.mp4" using FFMPEG and Python’s Popen. However, I’m getting some error. This error has popped up recently.

  I’ve been using https://github.com/chexov/image2pipe repository for frame extraction. However, even the examples mentioned in this code have stopped working.

      cmd = "ffmpeg -v error -skip_frame nokey -i twws.mp4 -vsync 0 -r 30 -s 
  
      300x300 -pix_fmt rgb24 -f image2pipe -"
  
  
  
      args = shlex.split(cmd)
  
  
  
      frame_ext_proc = subprocess.Popen(args,stdout=subprocess.PIPE, 
  
      stdin=subprocess.DEVNULL,bufsize=10**8)

  The error I received is as follows :

    File ".\test.py", line 97, in <module>
  
      decoder.start()
  
    File "C:\Users\g_host\AppData\Local\Programs\Python\Python36\lib\multiprocessing\process.py", line 105, in start

• FFMPEG shows bitrate=N/A and doesn't send anything

  20 mai 2019, par Mehul Jain

  I am trying to relay an stream from one rtsp url to another without recoding using this command :

  ffmpeg
 -rtsp_transport tcp
 -fflags nobuffer
 -re
 -i rtsp://xxx.xxx.xxx.xxx:554/[stream_name]
 -vcodec copy
 -an
 -f rtsp rtsp://yyy.yyy.yyy.yyy/[new_stream_name]

  But FFMPEG doesn’t stream anything and stats shows bitrate=N/A

  This is the exact output that i get :

  frame=  113 fps= 32 q=-1.0 Lsize=N/A time=00:00:06.77 bitrate=N/A speed=1.92x

  Although when i change output stream container to ’flv’ and protocol to ’rtmp’ it works.

  Any help will be appreciated.
