HDHomeRun Prime Tuner Locked (1 Viewer)

[georgius]

It seems that we need some review of problems, which we have/had:

1. locked and not released tuner - TEARDOWN request was sent on closed connection - solved
2. creating output pin - solved
3. buffer overflow error when parsing strings - solved
4. slow channel changes - at least two reasons
   1. filter wasn't designed to be called more times per session (creating and destroying instance) - changed, but not tested, testing build
      
   2. as I understand from @mm1352000 reply, the TV Server thinks that new channel is on the same frequency/multiplex as current channel, so it doesn't need to tune - probably not fixable

Do we have some other issues or problems which I forgot?

That's an excellent summary

Do we have some other issues or problems which I forgot?

Not for the filter, no.
For CableCARD tuners in general, I think only this one to add:

Build with dumping data and fixed first problem when calling Load() method multiple times.

Not so sure if this build fixed the issue. I saw it stall when I tuned to WNYE and another channel before it.

Please could you post the log files separately. I'm on a low internet data cap so not able to download the dump every time.

Sure thing You'll have to unzip each individual dump file because I can't upload them with their original extension.

Thanks
I really only needed the TVService.log file. It shows that TV Server thought these two channels were on the same frequency (physical channel), and therefore didn't send the tune request:

[2014-03-23 18:24:08,266] [Log ] [22 ] [INFO ] - atsc:Tune:ATSC:tv:Cable NJTV SD Freq:463250 ONID:174 TSID:0 SID:1013 PMT:0x1C3E FTA:False LCN:64 phys:64 maj:23 min:0 mod:Mod256Qam

This is the problem pointed out earlier:

This one I can understand and explain. TV Server thinks that INVESTIGATION DISCOVERY was on the same frequency/multiplex as SCIENCE CHANNEL, so it didn't need to tune... but with CableCARD tuners you always have to tune. It is difficult to solve this problem in TVE 3; the problem is already solved in the TVE 3.5 code.

I agree with mm and I didn't find any other problem. So, in first post of merged filer is build without dumping output pin data.

Ok... Tried the latest filter. Performance overall was better. Noted that tuners seemed to be releasing normally (no blinking tuner LED's etc.). For the most part channel changes were normal. I say for the most part because there were still some excessive channel change times with seemingly unnecessary switching to another tuner. However, these incidents seemed to occur much less frequently. I wonder what would happen if the other two tuners where in use and unavailable...

Currently I got MP 1.6.0. installed. Was considering installing MP 1.7.0 pre release. Will I need to install this filter after installing MP 1.7.0. if I want to keep using it?

This problem is not fixable and happen when current and next channel have same frequency. In that case is not send tune request and changing channel fail.

Channel will not be tuned.

More happy times with MediaPortal... So I tried MPUrlSourceSplitterWithDump.zip and things were working good. Didn't realize that it was creating these large log files even when not running in debug mode. Was made aware of that fact the hard way. It consumed all the space on my drive. Joy!. Tried the reverting filter installation procedure here. Something didn't work. Now TV doesn't work... No ability to turn TV on, or see the guide etc... Broke. That's the word. Attached the logs.

Irritation/frustration is setting in...

So can somebody tell me what I need to do now to repair MP?
