pub fn query_caps(&self, filter: Option<&Caps>) -> Caps[src]
pub fn query_caps(&self, filter: Option<&Caps>) -> Caps[src]Gets the capabilities this pad can produce or consume.
Note that this method doesn’t necessarily return the caps set by sending a
[crate::Event::new_caps()] - use [Self::get_current_caps()] for that instead.
gst_pad_query_caps returns all possible caps a pad can operate with, using
the pad’s CAPS query function, If the query fails, this function will return
filter, if not None, otherwise ANY. Read more
