Re: [libcvd-members] Open video error

[Gerhard Reitmayr]

Hi Gabriel,

you need to configure libcvd with  --enable-gpl so that the VideoFileBuffer is 
included. VideoFileBuffer uses ffmpeg libraries which are GPL (I guess) and not 
enabled by default, because it would propagate the GPL terms to the user's code.

cheers,
   Gerhard
