The error: In file included from k9avidecode.cpp:12:0: k9avidecode.h:35:91: error: 'AVFormatParameters' has not been declared Both AVFormatContext, and AVInputFormat are defined in /usr/include/libavformat/avformat.h, but AVFormatParameters is nowhere to be found. It used to be there: http://ffmpeg.org/doxygen/0.6/structAVFormatParameters.html How do I fix the code? A whole struct disappeared. Along with the drop of AVFormatParameters it looks like 'av_open_input_file' is deprecated in favor of 'avformat_open_input'. Thankfully there are only 4 instances of this in k9copy (k9author/k9avidecode.h k9author/k9avidecode.cpp). 17:19 archangel:/dat_e/tmp/src/k9copy> grep -r av_open_input_file * k9author/k9avidecode.h:typedef int (*av_open_input_file_t)(AVFormatContext **, const char *,AVInputFormat *,int, AVFormatParameters *); k9author/k9avidecode.h: av_open_input_file_t av_open_input_file; k9author/k9avidecode.cpp: av_open_input_file = (av_open_input_file_t)dlsym(FormatHandle,"av_open_input_file"); k9author/k9avidecode.cpp: if (av_open_input_file(&m_FormatCtx, _fileName.utf8(), NULL, 0, NULL)!=0) { How do you fix this? What is the lvalue and rvalue that need changing? The reason this is confusing is av_open_input_file seems to be used both as a name_t and by itself: Experts - what say you?
