[confirm] Graph building runs in an endless loop after switching channel (1 Viewer)

[disaster123]

Hi,

i can trigger this behaviour reproducable by switching between channels very often. In TvServer setup i can see that the tuning went fine.

Hi,
Not sure what you Hi,
I'm not able to reproduce this issue, tried 30 channel zaps without hitting this issue, maybe someone else can

Regards

Oh an additional notice this is mutliseat rtsp. Have you tried that?

Things to check:

• Is the issue reproducibe without MP audio renderer in use? If not then it is not a MP bug most likely (of course the renderer could just expose some bug)
• Disable preferred audio language
• Disable prefer AC3
• Test if 1.1.1 causes the same issue
• Test if TsReader from 1.1.1 helps

OK this is related to => GetPreferedAudio. If i disable prefer AC3 it does NOT happen. It also only happens when i switch to a channel where the default stream (0) is NOT AC3 but an AC3 stream is available in f.e. stream (1). But it does not happen everytime. I've to switch between two channels 5-10 times to trigger it.

There seems to be a loop between triggered audio change and changing the audio itself.

I think i'm able to trigger this with a 100% success value:

1.) you need to run rtsp multiseat
2.) you've to activate prefer AC3
3.) tune to a channel with only 1 available audio stream which must be MPEG
4.) tune to a channel with exacly 2 available auio streams where the 1st is MPEG and the 2nd is AC3

you get stuck...

could you check if you can reproduce it now?

Does that issue happen with older TsReader as well?

Hi
According to logs it looks same as already known issue
0002914: When using RTSP, audio/video format change may cause video playback to hang in a loop - MediaPortal Bugtracker

oh thanks but WHY is it tagged for future versions? I mean i really cannot watch live TV without stopping TV and starting it again when i want to switch a channel. This is AN absolute showstopper for watching live tv.

OK will fix this and some other stuff withn simply moving away from rtsp even in multiseat. It is nearly unusable in MP. The tvserver also crashes really often due to bugs in streamserver.dll, ...

Why isn't UNC mode default for multiseat. I think this would be muchn more stable for MOST of the users.
