capssetter
Sets or merges caps on a stream's buffers. That is, a buffer's caps are updated using (fields of) GstCapsSetter: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 GstCapsSetter: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 GstCapsSetter: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.
