[gst-devel] how to use dshowvideosrc

[Andres Colubri]

Hello,

Wouldn't be a good idea to have the function
gst_dshowvideosrc_get_device_name_values exposed in the header file
gstdshowvidesrc.h?
In this way, it would be possible to query the available directshow
capture devices from the program (without having to link dshow directly
from there,
since all the dshow stuff is resolved inside the wrapper).

Thanks,
Andres
