Robert:
    After I switch to branch release/2.8, the problem disappears.

HI ?, Could you sign with a name that we can use when reply?


ffmpeg has constantly moving API so issues like this are impossible to prevent, get everything work then a few months later ffmpeg breaks things...


You'll either need to come up with solution for these API changes and post these fixes to osg-submissions for us to merge or revert back to an older version of ffmpeg.


Robert.

Hi:

    All ! I cloned ffmpeg from https://github.com/FFmpeg/FFmpeg.git

After config osg with cmake-gui, when I run make, it reports below erros:
