• Running frei0r filters with ffmpeg - "Could not find module 'pixeliz0r'."

  4 avril 2016, par ksloan

  I installed frei0r using homebrew

  MacK:tmp kevin$ brew list frei0r
  
  /usr/local/Cellar/frei0r/1.4/include/frei0r.h
  
  /usr/local/Cellar/frei0r/1.4/lib/frei0r-1/ (119 files)
  
  /usr/local/Cellar/frei0r/1.4/lib/pkgconfig/frei0r.pc
  
  /usr/local/Cellar/frei0r/1.4/share/doc/ (4 files)

  Then I installed ffmpeg with the --with-frei0r flag, and everything compiled fine

  brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265 --with-frei0r

  I tried telling ffmpeg where my frie0r filters were installed with

  export FREI0R_PATH=/usr/local/Cellar/frei0r/1.4/lib/frei0r-1/

  I even created symlinks from the default locations ffmpeg checks...

  MacK:tmp kevin$ ls -l  /usr/local/lib/frei0r-1
  
  lrwxr-xr-x  1 kevin  admin  33  4 Apr 04:43 /usr/local/lib/frei0r-1 -> ../Cellar/frei0r/1.4/lib/frei0r-1

  But I’m still seeing this error :

  [Parsed_frei0r_0 @ 0x7f8938f003c0] Could not find module 'perspective'.
  
  [AVFilterGraph @ 0x7f8938f00160] Error initializing filter 'frei0r' with args 'perspective'
  
  Error initializing complex filters.
  
  Invalid argument

  Full output :

  I’ve run out of ideas to try next, what am I missing ? Any help would be greatly appreciated.

• Find the streaming url source of an online streaming tv station to record with ffmepg

  20 mars 2016, par AHC

  I am trying to look into the javascript streaming source of the following site http://www.aztv.az/canli/aztv-canli.htm to capture the url and to record it using ffmpeg.

  My goal is to get something like this running :

  ffmpeg -i rtsp://XXX.XXX.XXX.XXX:XXX/live.sdp -acodec copy -vcodec copy c:/test_recording.mp4

  I don’t know what protocol this website uses, rtsp, rtmp, http, etc.
  Could you please help me to resolve this ?
  I tried to look into the .js file in the source of the page, but it is a bit complicated to figure it out. here is the js script.
