No. When you use PROCESSHEADERS_OPTION_NAME, you should
only use that option and NOT set DECODEAUDIO_OPTION_NAME
and DECODEVIDEO_OPTION_NAME.

However, you want to design the dbus interface is fine with
me. This
looks like it would fix the problem of common properties
between
streams.

Really? I will try it.
As far as I know, when I used DECODEVIDEO_OPTION_NAME,
while not DECODEAUDIO_OPTION_NAME (just as thumbnail does).
I willnot get callback on OnStreamHeader() for audio.
