• Compile FFmpeg with librtmp ERROR : librtmp not found

  10 juin 2014, par 谢小进

  Environment : Mac OS X 10.9.2, Xcode 5.1.

  I have compiled librtmp, libogg and libspeex successfully, they are in the directories named fat-librtmp, fat-libogg and fat-libspeex , then I run the shell script as below to coompile them into FFmpeg :

  #!/bin/sh

  Unluckily, the config.log shows :

  check_pkg_config librtmp librtmp/rtmp.h RTMP_Socket
  
  pkg-config --exists --print-errors librtmp
  
  Package librtmp was not found in the pkg-config search path.
  
  Perhaps you should add the directory containing `librtmp.pc'
  
  to the PKG_CONFIG_PATH environment variable
  
  No package 'librtmp' found
  
  ERROR: librtmp not found

  I have googled and knew that configure contains a line enabled librtmp  && require_pkg_config librtmp librtmp/rtmp.h RTMP_Socket, which maybe be wrong. Right ? Can somebody help me to solve it ?

  UPDATE at 2014/06/10

  I think it’s about pkgconfig or something, so I have create a file named librtmp.pc at /usr/local/lib/pkgconfig, which contains below text :

  prefix=/usr/local/librtmp
  
  exec_prefix=${prefix}
  
  libdir=${prefix}/lib
  
  includedir=${prefix}/include
  
  
  
  Name: librtmp
  
  Description: RTMP implementation
  
  Version: v2.3
  
  Requires:
  
  URL: http://rtmpdump.mplayerhq.hu
  
  Libs: -L${libdir} -lrtmp -lz
  
  Cflags: -I${includedir}

  Also I have moved built librtmp to /usr/local. After above being done, I run the shell script again, but still same error ! Can somebody told me why and how to solve it ?

• FFmpeg compile error

  7 octobre 2014, par CaptainCook

  I get an error when compiling my project ffmpeg. I followed this guide : TheGuide.

  When I execute the command make I get this error message :

  AS  libavcodec/arm/mlpdsp_armv5te.o
  
  libavcodec/arm/mlpdsp_armv5te.S:88:9: error: unknown directive

  ...
  
  make: *** [libavcodec/arm/mlpdsp_armv5te.o] Error 1

  I do develop on a MAC with OS X mavericks.
