我如何编译FFMPEG中给出的示例程序.我无法编译,因为我收到错误,因为CODEC_TYPE_VIDEO未声明.任何人都可以建议我如何编译程序.我正在使用ubuntu 11.
这是第一个例子:
$ gcc -o tutorial01 tutorial01.c -lavutil -lavformat -lavcodec -lz
这是我得到的输出:
tutorial01.c: In function ‘main’: tutorial01.c:77:3: warning: ‘dump_format’ is deprecated (declared at /usr/local/include/libavformat/avformat.h:1462)
tutorial01.c:82:51: error: ‘CODEC_TYPE_VIDEO’ undeclared (first use in this function)
tutorial01.c:82:51: note: each undeclared identifier is reported only once for each function it appears in
