  Clean up and optimize weightp, plus enable SSSE3 weight on SB/BDZ

• ffmpeg creates empty flv files

  8 janvier 2012, par user1136924

  I'm trying to build avi to flv converter with c#.
  i'm using this code below (taken from here) but it produces empty flv files.
  please help figure this this out.

  on an button click the program takes the uploaded file from the upload box and creates a new flv file from it.

  thanks !
