sink_template

GstStaticPadTemplate sink_template

static

Initial value:

=
    GST_STATIC_PAD_TEMPLATE("sink", GST_PAD_SINK, GST_PAD_ALWAYS, GST_STATIC_CAPS_ANY)

Pad template — sink accepts any video caps. The downstream conversion (videoconvert/glupload) already happens upstream in qgcvideosinkbin.
