Capsfilter causes problems in master

[Matej Knopp]

Hi,

I updated gstreamer today and I'm having weird issue when using capsfilter.

I have following pipeline

audioconvert -> capsfilter -> audioresample

I set the following caps on caps filter:
audio/x-raw-int, endianness=(int)1234,signed=(boolean)true,
width=(int)16, depth=(int)16,
channels=(int)2,channel-positions=(GstAudioChannelPosition)<
GST_AUDIO_CHANNEL_POSITION_FRONT_LEFT,
GST_AUDIO_CHANNEL_POSITION_FRONT_RIGHT >
(note that there is no audiorate)

and I get the following warning:
GStreamer-WARNING **: pad audioresample0:sink accepted caps
audio/x-raw-int, endianness=(int)1234, signed=(boolean)true,
width=(int)16, depth=(int)16, channels=(int)2,
channel-positions=(GstAudioChannelPosition)<
GST_AUDIO_CHANNEL_POSITION_FRONT_LEFT,
GST_AUDIO_CHANNEL_POSITION_FRONT_RIGHT > although they are not a
subset of its caps audio/x-raw-int, endianness=(int)1234,
signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)48000….
(because there is no rate set in caps; The rate is later of course set
on buffer passed to elements)

What happens is that the exact same caps as I set on capsfilter is
also set on the downstream element sink. I don't understand why this
happens suddenly.The caps is supposed to filter format of the upstream
element, so why is it being sent downstream?

Can anyone clarify this behavior?

Cheers,
Matej
