To investigate why libmpeg3 fails to be used, you can add some debug
messages in
DirectFB-extra/interfaces/IDirectFBVideoProvider/idirectfbvideoprovider_libmpeg3.c
in function Probe() at line 998. Either fails to detect the stream or
it isn't
called at all for some other reason.
I put a print statement, D_ERROR() to check whether the filename was
right. It seems the Probe itself is not called ..so i was looking at
build warnings and or errors if any , and after a rebuild, i got a
slight difference in the error message [1] when running sample1
The only thing that i was able to find was an undefined symbol (pow),
but looking at the symbols in the dlobject, i can see pow in there
Still can't see what exactly is wrong though.
Thanks,
Manu
