Due to some changes in libavformat, the sample code at http://www.inb.uni-luebeck.de/~boehme/libavcodec_update.html no longer compiles correctly.

avcodec_sample.0.4.9.cpp: In function ‘int main(int, char**)’:
avcodec_sample.0.4.9.cpp:83: error: request for member ‘codec_type’ in 
    ‘pFormatCtx->AVFormatContext::streams[i]->AVStream::codec’, 
    which is of non-class type ‘AVCodecContext*’
avcodec_sample.0.4.9.cpp:92: error: cannot convert ‘AVCodecContext**’ 
    to ‘AVCodecContext*’ in assignment
avcodec_sample.0.4.9.cpp:105: error: ‘struct AVCodecContext’ has 
    no member named ‘frame_rate’
avcodec_sample.0.4.9.cpp:105: error: ‘struct AVCodecContext’ has 
    no member named ‘frame_rate_base’
avcodec_sample.0.4.9.cpp:106: error: ‘struct AVCodecContext’ has 
    no member named ‘frame_rate_base’

I've created a patch as well as a fixed example for the code. I'm not entirely sure about commenting out the frame rate correction hack, but those frame rate variables are no longer members of the AVCodecContext struct.

Also, for compiling under Debian, the recommended usage is not to change the include directives, but to use:

g++ `ffmpeg-config --cflags` -o filename filename.cpp 
    `ffmpeg-config --libs avformat --libs avcodec`
