    base: GstBaseSrc/GstBaseSink::get_caps: add (nullable) to `filter` · 89dfda56
    Sebastiano Barrera authored
    The virtual method named `get_caps` in both `GstBaseSrc` and
    `GstBaseSink` has a `filter` parameter which can be `NULL` (the
    default implementation in GstBaseSrc already considers the case).
    Before this commit, there was no gtk-doc annotation representing this
    fact, which caused the corresponding entry in the GIR file to also
    miss this fact.
    
    This caused bugs in other places, such inducing the Vala compiler to
    introduce a wrongly assert on `(filter != NULL)` in every
    implementation of the `get_caps` method implemented in Vala.
