[Bug] Duplicate Audio Tracks in *.mkv files (1 Viewer)

[Terra]

Hi there!

I noticed that when playing a MKV file with multiple or a single audio track the Audio Track Selection in MePo2 shows them duplicate.

Example:
videotest.mkv

1. Name: "Deutsch (AC3 5.1)"
   language=German
2. Name: "English (AC3 5.1)"
   Language=English

When I "play this file in MePo2 -> right click -> Choose Audio Stream" I see the following options to choose from:

• videotest: A: Deutsch (AC3 5.1) [ger] (ac3, 48000 Hz, 5.1, 384 kb/s) [default]
• videotest: A: English (AC3 5.1) [eng] (ac3, 48000 Hz, 5.1, 384 kb/s)
• videotest: A: Deutsch (AC3 5.1) [ger] (ac3, 48000 Hz, 5.1, 384 kb/s) [default] (AC3 6ch)
• videotest: A: English (AC3 5.1) [eng] (ac3, 48000 Hz, 5.1, 384 kb/s) (AC3 6ch)

I think this selection should only show 2 options. Also it would be nice if the prefix "videotest: A: " can be skipped for better legibility?

I don't see anything in the logs, if I should provide something please tell me

Edit:
Just noticed that subtitles seem to be fine, only audio tracks appear duplicate.

thanks & br

This happens if you have multiple filters in the built directshow graph that supports IAMStreamSelect (the ability to switch between different audio/sub tracks). MP2 does currently ask all filters for their supported streams and builds an unique list. We are doing this to support features of different filters (i.e. for subtitle sources that are not loaded by the splitter).

Problem here is, that the 2 filters provider a different formatted string names for the same streams, so you see them twice.

We will think about this...

I see
Just for reference then this is my AV graph according to GraphStudioNext:

Yes exactly this is the problem: both splitter and ffdshow allow changing the streams, but are naming them differently.

You can make a test and disable the ffdshow's stream selection feature and try again. You should have unique streams then. Can you confirm this?

Can you please tell me where I can change this? I couln't find anything in the ffdshow settings.

windows start menu -> ffdshow audio decoder settings -> "Stream Switcher" -> disable the checkbox on right side

I'm not using the FFDShow Audio Decoder but the LAV Audio Decoder. Couldn't find a setting there

LAV Audio Decoder

LAV Splitter

Your LAV Version is very old .. additionally to morpheus tipps you could try and update to 0.48.

I updated to 0.48 but I still cannot find such an option anywhere. If I can help you anymore I will try

I have the same problem on my HTPC.

I am using ffdshow audio decoder with hdmi passthrough and haali as splitter. The Stream switcher option in ffdshow config is disabled, i checked that. Also i see every audio stream 3 times, not just 2 times like Terra. And i havent even installed LAVFilter, as i dislike it ;p.

I could figure out that the first entry is from ffdshow, as it shows "filename: Audio DTS, 5.1, 48000Hz (libdts)", when changing the used codec in ffdshow config to libavcodec, it shows that in the menu. But the other two entries look the same (filename:A [Undetermined]), and i cant determin where they come from.
