Hi Karl,
not much info floating around about that, although your steps are
reasonably simple.
The directory interfaces/IDirectFBVideoProvider contains the "video
provider drivers" (note that the DirectFB-extra package has more
drivers, but I do not see a MNG driver hanging around).
If you want to add a driver, just copy a template one (e.g. the gif
driver), and add it to the Makefile.am (so use the autogen.sh script to
configure/build). At startup, DirectFB will load all drivers and adds
them to a pool. This will "register" the Construct() and Probe()
functions. Now if you create a video driver, all the registered Probe()
functions will be called (which the first 64 bytes of data of the
stream), until one replies DFB_OK which will trigger calling
Construct(). The other functions should be reasonably self-explanatory..

Hi all,
I was wondering how could I create a custom VideoProvider for, let's
say, playing MNG animations. I couldn't find any info on this subject.
Have anyone done this kind of work before? What are the steps involved
in this task so we could later on do a simple "CreateVideoProvider()"
in order to play and control a MNG animation.
If you guys have any documentation on this, it would be very appreciated.
Thanks,
[]'s
