Matroska audio files (.mka)
« on: September 03, 2008, 12:13:20 pm »
I was reading an old topic http://yabb.jriver.com/interact/index.php?topic=45972.msg315345#msg315345 where Yaobing write the following:
Quote
mka used to be not on the list of types playable in MC. We recently added it. Therefore you no longer need to rename mka to mkv. It should import and play.

That's true but .MKA files are treated as Video files, which is wrong: genres aren't the same.
Functionally it works, it's possible also to select tracks from the directx filter which is open.
I know that a full implementation should be a lot of work. I mean to add embedded playlist on "playing now"...
but for the moment to add such files as Music would be a nice improvement.

Can you explain a bit more please. What do you mean by "mka files are treated as video files". Are they imported with "Video" media type? If so, there may be a bug. I can not think of anything else, except that the configuration of it is under Video - all DirectShow playback options are under "Video", but that does not mean audio is treated as video.

They are imported with "Video" media type.
It' not difficult to correct them manually by changing type in tag to "audio". Then genre can be correctly assigned
But it's a bug as you said.

Despite of change the type to "audio" the file it's treated as video in directshow filters.

Here is a graph taken with MC

Your mka file is a video file because Haali Media Splitter treats it a video by creating a Video output pin. Are you sure it is an audio file? When you play, what do you see on screen?

The bug, if any, would be in Haali Media Splitter.

It's an audio file... I receive it from a friend who put the FLAC album, the embedded playlist and the cover of the album in .MKA file...
I see the cover in screen and in haali directshow icon appears the playlist... fully functional... this is that I am able to select which track to play.
It seems that this haali media splitter is used for both .mka and .mkv

In MC manually marked as "audio" it plays ok, it's correctly tagged and in selection by file type appears MKA among all the other file types it has my collection.

Yes, Haali Media Splitter is the filter to use for any Metroska files.
The problem is, whether the program that created your mka files mistakenly put a dummy video stream in the  file, or there is a bug in Haali so it mistakenly output a dummy video stream. I do not have a mka file to test myself, and I do not understand Matroska enough to say whether all mka files are supposed to behave like that.

When you play it, after changing the media type to audio, do you see anything unusual (such as a blank video window popping up)?

I can certain change the code a bit so that we always treat mka as audio.

I've tested such files with other of my players like Cowon jetAudio and plays the file exactly as MC, forced to read .MKA it opens Haali filter and show that's playing an .MKV file :)... all directshow players acts the same (WMP11 for instance). Players with internal codec like KMPlayer and VLC did the same but does opens Haali filter.

No, MC just open display screen and Haali splitter in tray.

This will be nice and surely wont affect people as .MKA isn't a common extension.
