• Can't play m3u8 file in VLC or decrypt it with ffmpeg

  22 septembre 2021, par Novice At Everything

  I have found and downloaded the m3u8 file using the developer tools in Edge. However, it won't play directly in VLC.

  


  I then downloaded all the segments referred to in the m3u8 file as well as the key and put them in the same folder as ffmpeg. The partial contents of the m3u8 file are :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:13
#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-PLAYLIST-TYPE:VOD
#EXT-X-KEY:METHOD=AES-128,URI="keyfile.txt",IV=0x00000000000000000000000000000001
#EXTINF:12,
seg-1-z.ts
#EXT-X-KEY:METHOD=AES-128,URI="keyfile.txt",IV=0x00000000000000000000000000000002
#EXTINF:12,
seg-2-z.ts
...
#EXT-X-KEY:METHOD=AES-128,URI="keyfile.txt",IV=0x0000000000000000000000000000013E
#EXTINF:8,
seg-318-z.ts
#EXT-X-ENDLIST


  


  The keyfile.txt contents are : eyJwYXNzcGhyYXNlIjoiNjE0YjQ5NTYzYTdlYiIsImNpcGhlcnRleHQiOiJlamZOTWRSZjltY3Z4R1JRTFg2cVMralJJTmZaUGJyMXVyaFhhTVZ1QVptSUpXZVdYMkZLQ0t1Q0ZCYUQwY3FYIiwiaXYiOiIxZTNlNzg3ZjNjYmRlOGViZDdlZTBkNWVhZDA1NmEzNCIsInNhbHQiOiIwNjc3M2I1OWE1Y2IxZjA3ODdkYmEzZTAwYWZmNGIzNyJ9

  


  This is what I get when I run ffmpeg :

  Can anyone help ? Thanks

• avfilter/vf_edgedetect : properly implement double_threshold()

  22 juin 2020, par Valery Kot

  avfilter/vf_edgedetect : properly implement double_threshold()
  Important part of this algorithm is the double threshold step : pixels
  
  above "high" threshold being kept, pixels below "low" threshold dropped,
  
  pixels in between (weak edges) are kept if they are neighboring "high"
  
  pixels.
  The weak edge check uses a neighboring context and should not be applied
  
  on the plane's border. The condition was incorrect and has been fixed in
  
  the commit.
