Allow browsing across tuners

[Ron Frazier <ron@…>]

I've put together a set of patches that allow users to view channels from all tuners in the LiveTV browse mode. It has the following features:

• Enabled via a toggle in TV Settings -> Playback OSD (disabled by default)

• Adds 2 extra attributes to the infoMap for use in the OSD

1) tuner = "Current Tuner", "Tuner #", or empty if no tuner is available for that channel 2) notuner = "No Tuners Available", or empty if a tuner is available for that channel

• Allows textarea objects in osd.xml (which maps to the OSDTypeText class) to support a fcnfont option. This allows you to do things like make the program title appear in red if there are no tuners available to watch the program.

I'm attaching 3 patches:

Patch 1: Implements the fcnfont support for OSD textarea objects.

Patch 2: Implements the actual tuner browsing featuers.

Patch 3: Demonstrates how to support the fcnfont in the blueosd theme. I am not necessarily proposing that this patch be applied as is...just providing an example of how the new UI features can be implemented in a theme.

Hi,

I'm also looking into this issue and came across your patches. I tried the browse_tuners.patch on its own, (with a few small mods needed to compile without the font patch), and it worked well. :)

There's always concern about additional network traffic and DB load generated by the channel checking and input groups checking stuff so I was experimenting trying to minimize that.

Came up with a patch with these changes for the browse_tuners.patch:

• Use TV::IsTunable?(), this eliminates the need for adding TV::GetProgramTunerStatus?() and TV::FindAvailableTuner?().
  

• Add TV::GetChanIDAnyTuner(const QString &chan) to avoid GetChanNum?() DB query.
  

• Reuse the ProgramInfo? from GetNextProgramAnyTuner?() to TV::BrowseDispInfo?(), saves re-getting the program info from the DB.
  

• Dropped TV::GetProgramTunerStatus?().
  

• Constify new functions.

I'd love to use this patch, as the people I'm building a mythbox for don't want to switch to the channel guide just to switch 1 channel.

There appears to be a problem with the ":BROWSETS" variable in some query:

2008-09-25 22:49:14.023 Query contains bind value ":BROWSETS" twice: SELECT DISTINCT program.chanid, program.starttime, program.endtime, program.title, program.subtitle, program.description, program.category, channel.channum, channel.callsign, channel.name, program.previouslyshown, channel.commmethod, channel.outputfilters, program.seriesid, program.programid, program.airdate, program.stars, program.originalairdate, program.category_type, oldrecstatus.recordid, oldrecstatus.rectype, oldrecstatus.recstatus, oldrecstatus.findid FROM program LEFT JOIN channel ON program.chanid = channel.chanid LEFT JOIN oldrecorded AS oldrecstatus ON program.title = oldrecstatus.title AND channel.callsign = oldrecstatus.station AND program.starttime = oldrecstatus.starttime WHERE program.chanid = :CHANID AND program.starttime <= :BROWSETS AND program.endtime > :BROWSETS GROUP BY program.starttime, channel.channum, channel.callsign, program.title ORDER BY program.starttime, atsc_major_chan,atsc_minor_chan,channum,callsign LIMIT 1000

I forgot to mention I'm using the latest trunk, not the fixes release. The patch does not cleanly apply to it, but with some tweaking I got it right.
