#12656: Tuner used more than one for same channel
-----------------------------------------+----------------------------

Type: Bug Report - General | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - General | Version: 0.27.6
Severity: medium | Keywords: tuner, backend
Ticket locked: 0 |
-----------------------------------------+----------------------------
MythTV 0.27.6, Ubuntu 14.04.3, HDHomeRun Connect dual tuner (UK),
connected peer to peer (link local). Frontend is Kodi 15.2, not MythTV
frontend, both on same and on other m/cs.
It appears viewing / recording the same channel in more than one place
causes more than on tuner to be used.
Watch BBC News (ch 92). Mythweb status shows one tuner used. On an android
tablet watch the same channel. Mythweb now shows both channels used. Try
it on a 3rd device, Kodi on that device says channel not available.
MythTV backend capture card setup for each tuner has max recordings set to
1 in recording options, because you have to - HDHR does not support
multiple channels from one multiplex like other tuners do. However I
believe that should apply to different channels on the same multiplex, not
the same one?
It appears that with this setup the backend will only allow one client to
use a channel stream, even if several clients want exactly the same
channel stream. I noticed this first when recording a channel and watching
it live on the backend m/c - used two tuners, not one.
The consequence of this is unexpectedly running out of tuners. Whilst this
specifically happens with my HDHR setup, perhaps it is general to all
tuners and is down to the backend not realising that multiple sinks
wanting the same channel source could be satisfied by the one source.
