Hi Amar Akshat,
please correct me if there's misunderstanding. I knew littlbe about uPnp and
Rygel, even i donot setup the environment to reproduce this issue yet. After
some google search and study, i assume the whole picture like below:
1) you're using some Andorid based uPnp player(like BubbleUPnP or other) as
control point and player software.
2) Rygel was running and you could get exported media files from other uPnp
devices through uPnp player.
3) Pa could export devices in the DLNA network, maybe local device or other
uPnp deivce has audio playback capability.
4) uPnp player could see above PA devices through Rygel system.
5) uPnpn player could choose media files and play them through previous
exported PA device.
In software level, i assume some operations like below:
1) Rygel get media data and send them to Gstreamer
2) Media data routed to Pulesaudio and send out to selected PA sink through
http-protocol. The issue is high latency here.
Still i donot quite understand the role of module-rygel-media-server here.
i need some time to get things clear. please let me know whether something was
wrong.
thanks
