  Note I added :

  if($srcAR<41000){ $srcAR = "41000"; }

  Above and its working !

• Cannot found yasm while i have installed it

  8 juin 2012, par user1201399

  I got a strange problem. I tried to install x264. When run sudo ./configure —enable-shared,
  it gave :

  Found no assembler
  Minimum version is yasm-0.7.0
  If you really want to compile without asm, configure with —disable-asm.

  But I already installed yasm-0.7.0 ,to prove that ,i run yasm —version,it gave :

  *yasm 0.7.0.2066
  Compiled on May 8 2012.
  Copyright (c) 2001-2008 Peter Johnson and other Yasm developers.
  Run yasm —license for licensing overview and summary.*

  I install yasm to /usr/local/yasm,
  Why can it not find yasm ?
