DTS 8193 not working, will it ever?

[Rick]

Some recent movies have the DTS 8193 audio codec that does not exist
in Perian nor QT. DivX fails to use it also. Only VLC.
-- So what one says, use VLC then.
--- Would be nice, but Air Video doesn't use VLC. And Air Video
converts most, but not this audio codec.
Even Handbrake fails to read it properly or even see the movie file at
times. All these movies are ripped MKVs, and I cannot control the
source or person who rips the movie.
I am hoping that 10.8 will have expanded support in its movie
streaming from one's hard drive (what Air Video via iPhone does)
rather than having to put everything into iTunes.

I have run Perian ever since a co-worker pointed it out to me about 4
years ago or so. It has been flawless behind the scenes, a great job
to all who provided this tool.

Hi,

the is the first time I hear about DTS 8193. Are you sure this is the
format name? I didn't get any relevant google results.

Kind regards,
Matej Knopp

Yes, this is what is reported on DivX and QuickTime for some movies. It does not recognize DTS 8193 codec, says it is needed.

QuickTime will not give you a name unless it has a codec for it.  It derives the names from the codec, not the file.

 

I have Perian, and everything else is updated to latest versions. I have had to download different rips of the same movies that do not have DTS only.

EG - The.Three.Stooges.2012.BluRay.Remux.1080p.AVC.DTS-HD.MA5.1-NYDIC - fails with the error
       - American.Reunion.2012.UNRATED.1080p.BluRay.DTS.x264-LEGi0N - runs OK, no error

It is not wise to publicly state that you've downloaded movies, especially giving examples of such.  Unless you own the BD disks from which these are ripped, you've just publicly admitted to piracy.

 

And even Handbrake does not convert those files, it fails to read them.

The video plays, no audio.

I can google DTS 8193 and get hits, references.

Read what Matej said.  He said he doesn't get any relevant results.  Do the search and explain how the hits do not look like a collection of disreputable sites.

Yeah, my bad, but...

To end it, I thus have to assume a file error of some kind and let it go.

That looks like a regular DTS audio. 8293 is code for WAVE_FORMAT_DTS2.

That explains why the Google search results for 8193 are so worthless.  Everyone who does anything with codecs knows that when you express part of the fourcc as a number, you do so in hex!  This just exemplifies yet another example of where the DivX folks just get things wrong.

Are these are avi files?  Why someone would put DTS audio is AVI is beyond idiocy, but I said the same for AC3, H.264, MPEG4, and so forth.

[Rick Prescott]

Thank you both for clarifying things, it seemed strange, but I guess some do not know what they are doing and don't check things. All I could find for 8193 referenced Windows old crap, nothing new, frustrating.

And I do not do windows (quote my wife - :D)

Not AVI files, mkvs. VLC runs it fine, thus adding to the confusion.

Something you may want to do is possibly try converting the file to MPEG-4, using a tool such as Handbrake. It utilises libVLC, so it could be a workaround to your problem?

In other scenarios I have come to the conclusion that it is sometimes simply easier to find a Windows machine and convert the file to MPEG-4. This gets around trying to find the obscure codec that was never ported to the Mac.

Did you actually read this thread before posting to it?  The original poster is talking about audio, not video.  Furthermore, one of the posters stated:

DTS audio is hardly obscure, given that it's on a decent number of DVDs and a majority of BluRays.  It is not a question as to whether the codec is present or not (Perian includes it), it is a question as to why the codec is not properly labeled inside an MKV file.  For some reason the MKV file was muxed using the codec definition one would expect to find inside AVI files instead of the pre-defined definition found in the MKV spec for DTS audio.

I did read the thread and the original author did mention DivX, so unless I missed something has audio and video, which can be converted by a tool such as Handbrake.

I realise DTS audio is common, though I simply made a general case for when I haven't been able to get stuff working. Certainly it would be better to get the original file read by Perian, but options (open source too) can't hurt.

He mentioned the DivX player, which is essentially a QT player.  I prefer NicePlayer over it myself, but the player is not the cause of the issue here (with the exception of a misleading error message).

Handbraking a 1080p file is quite an ordeal.  I've done it myself from BD sources and it takes about 4 hours on a quad-core machine.  Instead, I'd suggest running an mkvextract to extract the tracks, and then mkvmerge them together.  That should be a direct copy of the data, but have the advantage of properly marking the DTS audio as stated in the MKV spec.
