hi,

i tried to install opencv on my ubuntu system follow by:
http://opencv.willowgarage.com/wiki/InstallGuide_Linux

i got two errors when i tried to use "make" to build the library:

/home/cz/Webcam/trunk/opencv/src/highgui/cvcap_ffmpeg.cpp: In member function ‘virtual IplImage* CvCapture_FFMPEG::retrieveFrame(int)’:
/home/cz/Webcam/trunk/opencv/src/highgui/cvcap_ffmpeg.cpp:549: error: ‘img_convert’ was not declared in this scope

make[1]: *** [src/highgui/CMakeFiles/highgui.dir/all] Error 2
make: *** [all] Error 2
i googled a whole day yesterday, it seen like that ffmpeg recently change their file structure, but opencv did not follow the change.

how can i solve the problem? can anyone help me, please?
thanks in advance.
