Hello,
I'm trying to use ffmepg library in a nacl project.So far I was able to build
the library using NACL_ARCH=pnacl make ffmpeg and with the default configure
flags:
LogExecute ${SRC_DIR}/configure \ --cross-prefix=${NACL_CROSS_PREFIX}- \
--target-os=linux \ --enable-gpl \ --enable-static \
--enable-cross-compile \
--disable-inline-asm \ --disable-ssse3 \ --disable-mmx \
--disable-amd3dnow \ --disable-amd3dnowext \ --disable-indevs \
--enable-libmp3lame \ --enable-libvorbis \ --enable-libtheora \
--enable-libvpx \ --disable-ffplay \ --disable-ffserver \
--disable-demuxer=rtsp \ --disable-demuxer=image2 \ --prefix=${PREFIX} \
${extra_args}}
And in my project i use the following headers:
#include "libavcodec/avcodec.h" #include "libavformat/avformat.h" #include
"libswscale/swscale.h"
and in my makefile I use:
LIBS = nacl_io ppapi_cpp ppapi pthread \avformat vpx vorbisenc vorbis ogg
theoraenc \theoradec mp3lame m avcodec swresample avutil \avdevice avfilter
swscale
But when I run my makefile I get the following errors:
