• ffmpeg - "Could not find the codec parameters" (Live Stream)

  8 mai 2017, par Gagandeep Singh

  I am trying to record a live HTTP stream using the following command :

  ffmpeg -analyzeduration 2147483647 -probesize 2147483647  -i "http://mumsite.cdnsrv.jio.com/jioplay.catchup.cdn.jio.com/recordings/H8_S480_H264_MP/2556/1493919000.mp4/init/LIVEPROGRAM_CHANNEL_2556_START_1493919000_END_1493922600?uid=guest_uid&recid=SCHEDULED-A00B00C00D00E00F-_-_-2556_48168092&shard=shard_a&sid=77179867662431494241905&i=2&nwk=WIFI&pk=1&CurrentNetworkType=WIFI&CurrentNetworkType=WIFI" -c copy -absf aac_adtstoasc testing.ts

  Below is a screenshot of the ff-prompt console :

  http://i64.tinypic.com/331d55w.jpg

  It looks like the URL is correct but no data is being saved in the file and these warning messages are shown :

  multiple fourcc not supported

  Could not find codec parameters for stream 1 (Video : none (encv /
  0x76636E65), none, 576x432) : unknown codec

  How do I determine which codec would handle that stream or is the reason something else ?

  I’m trying to use the module save from matplotlib.animation.FuncAnimation.
  This is the part of the code I’m referring to :

  import matplotlib.animation as animation
  
  plt.rcParams['animation.ffmpeg_path'] ='/Users/edoardo/Downloads/ffmpeg-3.3/ffmpeg'
  
  ...
  
  """other code"""
  
  ...
  
  ani = animation.FuncAnimation(fig, update_mode, 250,
  
                                 interval=50, blit=False)
  
  ani.save('Resonant_modes.mp4', fps=30, extra_args=['-vcodec', 'libx264'])

  But I get this error as a result :

  ValueError: Cannot save animation: no writers are available.
  
  Please install mencoder or ffmpeg to save animations.

  The problem is that I have installed ffmpeg, so I don’t know what to do.
  Could someone explain to me how to do and where should I move the executable ffmpeg file so than Python can find it easly ?

  Edit 1 :
  I’m using mac os x
  FFmpeg should be installed correctly, here’s the output from Bash :

  MBP-di-Edoardo:~ edoardo$ ffmpeg ffmpeg version 2.8.6 Copyright (c)    
  
  2000-2016 the FFmpeg developers built with gcc 4.8.5 (GCC) 
  
  ...more stuff ... 
  
  Use -h to get full help or, even better, run 'man ffmpeg' –

  Edit 2 :
  I’ve tried moving the file to \bin but even using sudo I can’t

  sudo cp ffmpeg /bin
  
  Password:
  
  cp: /bin/ffmpeg: Operation not permitted

  When I run this command :

  ffmpeg -y -i ./in.mp4 -c:v png -f image2pipe -thread_queue_size 1024 -r 25 -t 186.75 -i - -filter_complex overlay=0:0 -c:v libx264 -pix_fmt yuv420p -movflags +faststart ./out.mp4 < ./out.png

  I get an error :
