TV Client audio language preference (1 Viewer)

[findftp]

Hello,

Before I post a bug (with all necessary), I would like to know if the TV client should be able to give different languages different priorities.
I've attached a picture of the client where at the right side you can put languages. You can also move them up and down which should indicate that they would have different priorities. However, I don't see those 'priorities' mentioned at http://wiki.team-mediaportal.com/MediaPortal/Configuration/Television/TVClient. Obviously, moving them up and down should indicate that it means different priority.

I noticed that when enabled 'Prefer AC-3 sound' language priorities are being ignored (with 'Prefer audiotype over language' turned off!)

Can someone confirm (or rather deny) that this is correct behavior? If not, I will fill in a correct bug report.

Thanks for helping.

Hi findftp

If you have "prefer AC-3" sound ticked and "prefer audiotype over language unticked" then my understanding is that the stream selection logic should be as follows:

1. Are there any streams with languages matching any preferred language? If "yes", discard streams that don't match preferred languages and go to step 2. If "no", go to step 3.
2. Prioritise the remaing streams according to language priority and select the stream(s) with the highest priority available. If there is only one stream for the highest prioritised language then choose that stream. If there are mulitple streams with the same same highest prioritised language then discard the streams for the other languages and go to step 3.
3. Prioritise the remaining streams by stream type - if the stream is AC3/DD then it is higher priority than AAC and MPEG streams. If there is only one AC3/DD stream then choose that stream. If there are multiple AC3/DD streams then choose the first one. If there are no AC3/DD streams then just choose the first [non AC3/DD] stream.

Here is an [unrealistic] example. Say you have a channel with the following streams:
1. deu/AC3
2. deu/AC3
3. eng/AC3
4. ita/AC3
5. deu/MPEG
6. eng/MPEG
7. ita/MPEG

Language priorities are:
1. fre
2. deu
3. eng

Prefer AC-3 is ticked.
Prefer audiotype over language is unticked.

Now we apply the logic:
- In step 1 we discard streams 4 and 7 since they don't match any preferred language.
- In step 2 we discard streams 3 and 6 since they don't match the highest priority language which is available (deu).
- In step 3 we first discard stream 5 since we prefer AC3/DD audio, then we select stream 1 as it is the first AC3/DD stream.

A little tricky but hopefully you can follow that logic. If the description matches what you expected but you don't see that happening in practise then please post logs and describe what you expected to happen.

Hi mm1352000,

Thank you for your clear answer. I also thought it should work the way you explain, however, it is not happening.

First situation (MediaPortalLogs_03_01_12__17_54.zip, settings1.png, channel1-1.png and channel1-2.png)
Prefer AC3 is ticked, language over type is unticked.

Language preference:
1. nld
2. dut
3. eng

viewing channel 1-1.png:
dut MPEG1
eng AC3
-> eng AC3 is automatically selected while it shouldn't be.

viewing channel 1-2.png
ger MPEG1
eng MPEG1
fra MPEG1
ita MPEG1
spa MPEG1
-> eng MPEG1 is correctly selected (probably because nld and dut are unavailable?)


------------------------------------------------------------

Second situation (MediaPortalLogs_03_01_12__17_59.zip, settings2.png, channel2-1.png and channel2-2.png)
Prefer AC3 is unticked, language over type is unticked.
Language preference:

1. nld
2. dut
3. eng

viewing channel 2_1.png:
dut MPEG1
eng AC3
->dut MPEG1 is correctly selected.


viewing channel 2-2.png
ger MPEG1
eng MPEG1
fra MPEG1
ita MPEG1
spa MPEG1
-> eng MPEG1 is correctly selected



It seems that 'prefer audiotype over language' is working while it is unticked.

Anyone please?
Do I need to add some extra information to be more helpfull?
Can somebody point me in the right direction of the source code? I'm willing to read it and find the 'error' myself.

In MePo 1.2.3 this bug is still present.
'Prefer AC3' ignores the language preference.
At the other hand, I much more like to see 1.3.0 to be finished than solving this problem.
