Improvement/regressions in handling multi channel [#13879]

Post by jwhitworth »

Not sure if I should have added this to the other multi channel thread.

2057

5.1 channels (6: FL FR FC LFE SL SR)is listed as 5.1
5.0 channels (5: FL FR FC BL BR) is listed as 5.0
4.1 channels (5: FL FR LFE SL SR) is listed as 5.0 ***
4.0 channels (4: FL FR BL BR) is listed as 4.0
3.0 channels (3: FL FR FC) is listed as 2.1 ***

2058

5.1 channels (6: FL FR FC LFE SL SR)is listed as 5.1
5.0 channels (5: FL FR FC BL BR) is listed as 4.1 (regressed from 2057 to 2058)
4.1 channels (5: FL FR LFE SL SR) is listed as 4.1 (fixed from 2057 to 2058)
4.0 channels (4: FL FR BL BR) is listed as 4.0
3.0 channels (3: FL FR FC) is listed as 2.1 ***

*** = incorrect handling of channel info

The changelog does not indicate any changes in how multi channel audio is analyzed.

There was only changed default for 5 channels, it is displayed as 4.1 now.
As I have written before, MM cannot detect LFE presence yet, so cannot differentiate between 5.0 and 4.1, already tracked as: http://www.ventismedia.com/mantis/view.php?id=13879

OK. Noticed a change. Was not sure what caused it.

Can you please upload somewhere sample tracks of your tests and then give me a DL link in PM so that we can test and document exact issues.

Also it seams that Audio multi channel and Video Multi Channel (even there is indication of difference from DVDs and BDs) and can you confirm that also?

I will work on gathering samples for the audio and send you the PM when done (have to find small samples). I have not dealt with video using MediaMonkey. That will require more tinkering.

3p0 (3 FL FR FC)
4p0 (4 FL FR BL BR)
4p1 (5 FL FR LFE SL SR)
5p0 (5 FL FR FC BL BR)
5p1 (6 FL FR FC LFE SL SR)

Note the variability of nomenclature for the rear channels. They can be indicated as either (SL and SR) or (BL and BR). I have seen (RL and RR) as well but cannot track down a sample. In the provided samples it would probably not make any difference since determination of the correct naming could be made using the presence of the LFE channel and everything would fall into place.

However there does exist 7.1 channel audio now (maybe 7.0 as well). In that case the difference could be important.

7.1 sound will be even more common in video.
