Re: [Paraview] git master and latest ffmpeg
Hi,
I'd like to suggest the attached patch as a starting point. It gets PV compiled
again against ffmpeg svn head. On 32 and 64 bit Linux and 64 bit Solaris systems
I did not observe any side effects yet (using gcc only to compile PV, though).

FYI, It is on my todo list to
1. restore dash16 to build VTK against the old FFMPEG
2. potentially setup a new dashboard that builds against at least a more
recent version.

It's just
