  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • 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,

...
#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 :

  • 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.
