Hi Everybody,
(sorry for inconvenence: ffmpeg-user can't receive this big email, it limited in 60KB, I just want you to see full error message)
I compiled ffmpeg-0.11.1 on linux, I want to use its library and header in a small specific c program to use av_register_all() in ffmpeg library,
I am having trouble in linking ffmpeg.
0) I use Centos 6.3 for a linux machine.
1) I have compiled ffmpeg-0.11.1 in /root/ffmpeg-source/working/ffmpeg ( I use 'configure' and 'make', not use 'make install' because i want to manage ffmpeg in a specific directory)
./configure --enable-gpl --enable-avfilter --enable-swscale --disable-shared --enable-libmp3lame --enable-libtheora --enable-libvo-aacenc --enable-libvorbis --enable-libvpx --enable-libx264 -- enable-version3
make
2) I make a test.c in /root/ffmpeg-source/working/test.c as below:
#include "libavcodec/avcodec.h"
#include "libavformat/avformat.h"
#include <stdio.h>
int main()
{
avcodec_register_all();
avfilter_register_all();
av_register_all();
printf("Test FFmpeg library! \n");
return 1;
}
2.1) make a link inside working:
ln -s ../ffmpeg ffmpeg
3) I make a Makefile in /root/ffmpeg-source/working/ as below:
PROGRAM = test
INCLUDEDIRS = -Iffmpeg/
LIBDIRS = \
-L./ffmpeg/libavcodec \
-L./ffmpeg/libavformat \
-L./ffmpeg/libavfilter \
-L./ffmpeg/libpostproc \
-L./ffmpeg/libswresample \
-L./ffmpeg/libswscale \
-L./ffmpeg/libavdevice \
-L./ffmpeg/libavutil
LIBS = -lpostproc -lswresample -lswscale -lavfilter -lavdevice -lavformat -lavcodec -lavutil -lm -ldl -Wl
CXXSOURCES = test.c
CXXOBJECTS = $(CXXSOURCES:.c=.o)
HEADERFLAGS = $(INCLUDEDIRS)
CXX = gcc
LDFLAGS = $(LIBDIRS) $(LIBS)
all: $(PROGRAM)
$(PROGRAM): $(CXXOBJECTS)
$(CXX) -o $@ $(CXXOBJECTS) $(LDFLAGS)
test.o: test.c
$(CXX) $(HEADERFLAGS) -c -o test.o test.c
clean:
$(RM) -f $(CXXOBJECTS) $(PROGRAM)
=> When I compile:
[root at CENT6 working]# make
gcc -Iffmpeg/ -c -o test.o test.c
gcc -o test test.o -L./ffmpeg/libavcodec -L./ffmpeg/libavformat -L./ffmpeg/libavfilter -L./ffmpeg/libpostproc -L./ffmpeg/libswresample -L./ffmpeg/libswscale -L./ffmpeg/libavdevice -L./ffmpeg/libavutil -lpostproc -lswresample -lswscale -lavfilter -lavdevice -lavformat -lavcodec -lavutil -lm -ldl -Wl
