georgius, have you ever switched to fullscreen TV? from your description isn't clear what is "MP main screen"
[Bug] Tvservice cpu usage increase problem while .ts playback fullscreen (19 Viewers)
- Thread starter SciDoctor
- Start date
I'm sorry, but I didn't mentioned it, I didn't switch MP to fullscreen. I can make same tests with MP switched to fullscreen. MP main screen is first screen with buttons (TV, Radio, ...), doesn't matter if fullscreen or not.
The whole point of this bug is what happens to TV server CPU usage when TV on client is switched to fullscreen.

Attached is TvPlugin.dll with mod applied for 1.2.0 Beta - drop it into 'C:\Program Files\Team MediaPortal\MediaPortal\plugins\Windows'

I was still getting the problem of the miniEPG and programInfo screens not showing the current channel info for first time they are opened after starting TV (the OSD was OK with the v2 patch), so I added 'TVHome.Navigator.CheckChannelChange();' in the relevant methods - patch attached (against current SVN).

OK, I'll make same tests on fullscreen, should I test with gibman's patch or with Owlsroost's patch?

Thanks
Downloaded and will test and feedback tomorrow at 11.30 ish.

The test needs to involve the following conditions, allow at least 30 seconds in each screen to ensure cpu usage stabalises.
1. Tv On (or TS file playback) in fullscreen, no OSD menus
2. Tv ON (or TS file playback) in fullscreen OSD menu showing (except TOPBAR and bottom bar; these make no difference )
3. Tv On (or TS file playback) within UI showing; any will do HOME, RECORDINGS, TV Guide etc
The issue is that in 1. the TVSERVICE cpu usage increase dramaticaly (obviously depends on your total cpu power) with respect to 2. and 3. My increase is from about 4% to 25-30%
Thanks
I made tests with no patch, with gibman's patch and with Owlsroost's patch. Testing procedure was:
Probably I didn't correctly understand what is OSD in SciDoctor's post. If you mean another window, please, specify it and I can retest again. From results you can see, that between gibman's patch and Owlsroost's patch aren't performance differencies (at least in my environment). I can confirm that both patches lowers CPU usage against not patched version of TV plugin. But both patches have still strange behaviour in MP TV home main screen (without playing TV). They both have higher CPU usage agains CPU usage while playing TV.
- start TV service
- start performance monitoring
- start MP in fullscreen
- stay 30 seconds in MP main screen
- swicth to MP TV home screen
- stay 30 seconds in MP TV home screen
- started TV and switched to fullscreen (no menu, OSD, just pure video)
- watch 30 seconds
- show OSD (information in bottom part)
- wait 30 seconds
- show TV guide with TV in lower left corner
- wait 30 seconds
- stop TV
- stay 30 seconds in MP TV home screen
- switch to MP main screen
- stay 30 seconds in MP main screen
- close MP, stop TV service, stop performance monitoring

This has corrected the problem, there is no longer a substantial cpu increase in tvserver with cpu staying within 1-4% instead of peaking at 25-30%.
The plus points are that now when system cpu approaches 100% for long periods ie epg grab/update the UI is smoother and responsive and the Heartbeat monitor is less likely to disconnect from the server.
What this has highlighted though is that there seems to be some excessive polling in TVHOME when no video is playing, nothing as dramatic as the corrected bug but there is an increase in cpu usage from 1-3% to 9-11% for tvservice; this maybe a necessary working within TVHOME and not a bug. (I have noticed this for some time in 1.1.3 and some previous releases, it was a problem some years ago and reduced with a fix by tourettes if I remember)
