Bug ID: 794143
Summary: support for rtsp onvif audio backchannel does not
work correctly
Classification: Platform
Product: GStreamer
Version: git master
OS: Windows
Status: NEW
Severity: critical
Priority: Normal
Component: gst-rtsp-server
Assignee: gstreamer-bugs at lists.freedesktop.org
Reporter: willdaihongjun at gmail.com

GNOME version: ---
Try to play back with the test-onvif example as client from
gst-plugins-good/tests/examples/rtsp.
But made a little modification on the source code of the test-onvif-backchannel
example from gst-rtsp-server\examples\test-onvif-backchannel.c.
The original backchannel pipeline is created by code snippet
gst_rtsp_onvif_media_factory_set_backchannel_launch
(GST_RTSP_ONVIF_MEDIA_FACTORY (factory),
"( capsfilter caps=\"application/x-rtp, media=audio, payload=0,
clock-rate=8000, encoding-name=PCMU\" name=depay_backchannel ! rtppcmudepay !
fakesink async=false )");
which is replaced by the following code
gst_rtsp_onvif_media_factory_set_backchannel_launch
(GST_RTSP_ONVIF_MEDIA_FACTORY (factory),
"( capsfilter caps=\"application/x-rtp, media=audio, payload=0,
clock-rate=8000, encoding-name=PCMU\" name=depay_backchannel ! rtppcmudepay !
mulawdec ! directsoundsink )");
which create backchannel pipeline to play back with directsoundsink.
gst-rtsp-server print the error message on console like
rtspclient rtsp-client.c:1744:handle_play_request: client 0000000002DF6E00:
unsuspend failed.
