How can I set up SoX to work with FFMPEG?
I have asked it here with details ->
http://stackoverflow.com/questions/21187420/ffmpeg-with-sox-configure-error-cannot-find-ffmpeg
But I will copy it here:
-------------------------
So I am trying to install in my Ubuntu Desktop 12.04 SoX with FFMPEG
support for m4a files.
I have followed this
<http://trac.ffmpeg.org/wiki/UbuntuCompilationGuide>instructions to
install FFMPEG, installing only certain encoders. Finally,
this is my set up:
ffmpeg version git-2014-01-17-3ca7085 Copyright (c) 2000-2014 the
FFmpeg developers
built on Jan 17 2014 12:36:01 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)
configuration: --prefix=~/ffmpeg_build
--extra-cflags=-I~/ffmpeg_build/include
--extra-ldflags=-L~/ffmpeg_build/lib --bindir=~/bin --extra-libs=-ldl
--enable-gpl --enable-libass --enable-libfdk-aac --enable-libmp3lame
--enable-nonfree
libavutil 52. 62.100 / 52. 62.100
libavcodec 55. 48.101 / 55. 48.101
libavformat 55. 23.103 / 55. 23.103
libavdevice 55. 5.102 / 55. 5.102
libavfilter 4. 1.100 / 4. 1.100
libswscale 2. 5.101 / 2. 5.101
libswresample 0. 17.104 / 0. 17.104
libpostproc 52. 3.100 / 52. 3.100
Hyper fast Audio and Video encoder
Then, I wget SoX 14.4.1 version and try to configure with FFMPEG support
like this:
./configure --with-ffmpeg
But I get this error:
checking for FFMPEG... no
checking libavformat/avformat.h usability... no
checking libavformat/avformat.h presence... no
checking for libavformat/avformat.h... no
checking ffmpeg/avformat.h usability... no
checking ffmpeg/avformat.h presence... no
checking for ffmpeg/avformat.h... no
configure: error: in `~/sox-14.4.1':
configure: error: cannot find ffmpeg
See `config.log' for more details
So I try to set PKG_CONFIG_PATH environment variable:
PKG_CONFIG_PATH=~/ffmpeg_build/lib/pkgconfig
./configure --with-ffmpeg
Getting:
checking for FFMPEG... yes
checking libavformat/avformat.h usability... yes
checking libavformat/avformat.h presence... yes
checking for libavformat/avformat.h... yes
checking for av_open_input_file in -lavformat... no
configure: error: in `~/sox-14.4.1':
configure: error: cannot find ffmpeg
See `config.log' for more details
Checking 'config.log' I see the following error:
| #define HAVE_LIBAVFORMAT_AVFORMAT_H 1
| /* end confdefs.h. */
|
| /* Override any GCC internal prototype to avoid an error.
| Use char because int might match the return type of a GCC
| builtin and then its argument prototype would still apply. */
| #ifdef __cplusplus
| extern "C"
| #endif
| char av_open_input_file ();
| int
| main ()
| {
| return av_open_input_file ();
| ;
| return 0;
| }
configure:15862: result: no
configure:15935: error: in `~/sox-14.4.1':
configure:15937: error: cannot find ffmpeg
What am I missing here?
Thx!
