cvcap

[Bluefuture]

Hi all,

In cvcap.cpp this is the sequence of the domains on testing video api:
       
        #ifdef HAVE_VIDEOINPUT
               CV_CAP_DSHOW,
        #endif
                       CV_CAP_IEEE1394,   // identical to CV_CAP_DC1394
                       CV_CAP_STEREO,
                       CV_CAP_VFW,        // identical to CV_CAP_V4L
                       CV_CAP_MIL,
                       CV_CAP_QT,
                       CV_CAP_UNICAP,
                       -1
       
        So first test if there is a firewire camera attached with
        DC1394_2,
        DC1394, CMU1394, GSTREAMER.
       
        But as you can see in cvcap_gstreamer.cpp case
        CV_CAP_GSTREAMER_1394: is
        empty. So if i have gstreamer enabled and i have a Vl2 or vl1
        camera i
        cannot use because i'm still blocked by CV_CAP_IEEE1394 case on
        gstreamer.
       
        I also want to try to create the writer code from gstreamer
        backend  i doesn't know is Nils Hasler is on ml and could polish
        some of comments in the backend code so that it will be a little
        be more understandable.
         I can't understand if comment are old code or a
attempt
to restructure the code.
       
        P.s. the last thing. I doesn't see any support for encapsulation
        format
        in the cvcap video writer abstraction api.
