[gst-devel] Mastroska muxer 0.9 port (unit testing)

[Michal Benes]

Hi Thomas,

I have started the work on the Matroska muxer unit tests. First of all,
let me say, I really appreciate that there is unit testing support in
GStreamer.

Now, I have some question about the testing: 

I was trying to use gst_check_setup_sink_pad. However, this fails since
matroska muxer references its source pad twice (one reference for
GstMatroskaMux and one for GstEbmlWrite). Does this mean that matroska
muxer behaves incorrectly or just that I should not use
gst_check_setup_sink_pad?

Also, I can not use gst_check_setup_src_pad since all muxer sink pads
are on request pad (and none of them is called "sink"). Could a new
function be implemented which takes the name of the sink pad as
parameters?

	Regards
		Michal
