Hi,
For the first error, this is because you need to copy the FFMpeg dll to the execution directory.
If you are using the 0.7.6 source archive:
You'll find them under : \Refs\FFMpeg\ffmpeg-r10461-gpl-lshared-win32\dll\
You should copy them to : \Root\bin\Debug\ for example.
For the second one, it's my big mistake... I have left absolute path for dependencies directories...
In the projects settings (Alt+F7) go to C/C++ > General > Additional Include Directories, and replace everything that is before \Refs, by "..\.."
(Complete path would be : "..\..\Refs\FFMpeg\ffmpeg-r10461-include" )
Do the same in Linker > General > Additional Library Directories.
(Complete path : "..\..\Refs\FFMpeg\ffmpeg-r10461-gpl-lshared-win32\lib")
Note:
You may want to use the source code repository from CodingTeam.net forge as it is more up to date.
Launch your SVN client and do a checkout using the url :
http://svn.codingteam.net/code/kinovea
It shouldn't have the absolute/relative paths problem.
