1../configure --enable swscale2.make3.make install正常安装结束。此时/usr/local/include下会多出一个ffmpeg文件夹，里面有一些头文件，以后要用到。/usr/local/lib下会多出libavformat.a,libavcodec.a,libavutils.a，这几个静态库在编译output_example.c的时候要用到。4.gcc -o hh output_examples.c错误： output_example.c:34:22: avformat.h: 没有那个文件或目录output_example.c:35:21: swscale.h: 没有那个文件或目录output_example.c:45: `SWS_BICUBIC' undeclared here (not in a function)output_example.c:52: parse error before '*' token...解决：需要添加引用头文件的位置5.gcc -o hh output_example.c -I/usr/local/include/ffmpeg错误： /tmp/ccW5CPkd.o(.text+0xf): In function `add_audio_stream': : undefined reference to `av_new_stream'/tmp/ccW5CPkd.o(.text+0xa0): In function `open_audio': : undefined reference to `avcodec_find_encoder'/tmp/ccW5CPkd.o(.text+0xda): In function `open_audio':...解决：为编译选项添加要用到的静态库（就是前面提到的那三个.a库）6.cp /usr/local/lib/libav*a /usr/lib gcc -o hh output_example.c -I/usr/local/include/ffmpeg -lavformat -lavcodec -lavutil错误： /tmp/ccI2Tg2J.o(.text+0x1f4): In function `get_audio_frame': : undefined reference to `sin'/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavformat.a(mov.o)(.text+0x211d): In function `mov_read_cmov':/tmp/ffmpeg/libavformat/mov.c:1186: undefined reference to `uncompress'/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavcodec.a(mpegvideo.o)(.text+0x28b0): In function `ff_print_debug_info':/tmp/ffmpeg/libavcodec/mpegvideo.c:1328: undefined reference to `cos'...解决：添加lmath库7.gcc -o hh output_example.c -I/usr/local/include/ffmpeg -lavformat -lavcodec -lavutil -lm错误： /usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavformat.a(mov.o)(.text+0x211d): In function `mov_read_cmov':/tmp/ffmpeg/libavformat/mov.c:1186: undefined reference to `uncompress'/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavcodec.a(cscd.o)(.text+0xb1): In function `decode_frame':/tmp/ffmpeg/libavcodec/cscd.c:168: undefined reference to `uncompress'/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavcodec.a(dxa.o)(.text+0xde): In function `decode_frame':/tmp/ffmpeg/libavcodec/dxa.c:233: undefined reference to `uncompress'/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../libavcodec.a(flashsv.o)(.text+0x3e): In function `flashsv_decode_init':...解决：添加zlib库8. gcc -o hh output_example.c -I/usr/local/include/ffmpeg -lavformat -lavcodec -lavutil -lm -lz错误undefined reference to `BZ2_bzDecompressInit'解决添加库gcc -o hh output_example.c -I/usr/local/include/ffmpeg -lavformat -lavcodec -lavutil -lm -lz -lbz2

编译成功。10.运行编译出来的东东。[root@localhost ffmpeg]# ./hhusage: ./hh output_fileAPI example program to output a media file with libavformat.The output format is automatically guessed according to the file extension.Raw images can also be output by using '%d' in the filename
本人使用的ffmpeg是0.6的版本。前面7条是转载别人的文章，后面两条是我遇到的问题以及解决方法。
希望以上对入门者有点帮助。
