mfvideosrc: add a video device dialog (feature request)
the libavdevice offer a show_video_device_dialog option that if set to true, before capture starts, popup a display dialog to the end user, allowing them to change video device properties and configurations manually.
would it be possible to add such option to mfvideosrc? this is especially usefull when capturing a webcam because sometimes the user want to change some device setting before the capture start
thank you
