Description

Sets or merges caps on a stream's buffers. That is, a buffer's caps are updated using (fields of) “caps”. Note that this may contain multiple structures (though not likely recommended), but each of these must be fixed (or will otherwise be rejected).

If “join” is TRUE, then the incoming caps' mime-type is compared to the mime-type(s) of provided caps and only matching structure(s) are considered for updating.

If “replace” is TRUE, then any caps update is preceded by clearing existing fields, making provided fields (as a whole) replace incoming ones. Otherwise, no clearing is performed, in which case provided fields are added/merged onto incoming caps

Although this element might mainly serve as debug helper, it can also practically be used to correct a faulty pixel-aspect-ratio, or to modify a yuv fourcc value to effectively swap chroma components or such alike.
