--- Comment #5 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
codec_data is used when it's out-of-band information that needs to be signalled
outside of the data stream.

streamheaders would be used in GStreamer to signal out-of-band information that
when prepended to the actual stream data still results in a valid stream (e.g.
you could signal H264 byte-stream SPS/PPS in caps as streamheaders for an H264
byte-stream stream).

Your claim "This is not correct" seems dubious, since what is in codec_data for
which caps is entirely a GStreamer convention, and so far the convention has
been that codec_data is only in caps for raw aac, and must be in caps for raw
aac.

Anyway, let's backtrack and figure out what you want to do in which specific
scenario.

Could you describe the specific scenario you want to make work but can't make
work currently?
