Matroska with XCD / playback with MPC

[goweropolis]

Hi guys,

I searched through some threads but had trouble finding answers, so I'll throw out a couple of questions here:

1. I burned a Matroska (MKV) file to XCD. When I tried to play it back via The Core Media Player (TCMP), the audio streams disappeared. I wasn't able to select any of the audio streams or chapters but I could with the original MKV file on my hard drive. It also automatically played the second audio stream (director's commentary). MKV was muxed with VDubMod. According to this thread (http://forum.doom9.org/showthread.php?s=&threadid=61036), XCDs only work with Gabest's filter. Are there any plans to fix this?

2. I downloaded Media Player Classic (MPC) and tried using that to watch the XCD, and the playback was slow & jittery. Am I doing something wrong? Do I need to install another filter/splitter or something?

TCMP is good, but I like the simplicity of MPC, and would like to be able to use it for my MKV files.

I should't say this but why you use xcd?

One single scratch and your files are gone. You can't even make back ups.

It looks like xcd is dead project. Why not make instead 2 or even 3 cd rips?

Please no flamewars. Just my opinion.

I used XCD because I thought it would be more convenient to have an extra 100 MB for the file, so I could improve the video quality. Don't have a DVD burner... yet :rolleyes: I guess I didn't think I would miss the error correction. I usually try to take good care of my CDRs.

Hey, nothing wrong with an opinion. That's the point of a discussion board isn't it? :)

I believe you need the CoreVorbis direct show filter for playback of vorbis audio from a mkv (it is choppy if you use the 'normal' ogg ds filters). I am not sure if this applies to MPC (MPC has lots of built-in filters) but I imagine it does if you hare having choppy playback problems. Does the file play fine off the hard drive in MPC?

About error correction, with xcd's it is true it is very easy to lose data off of a CD but one of the points to using matroska (AFAIK) is that one little error doesn't break the file. A movie on an XCD with a scratch would have a few frames messed up but would be playable (depending of the size of the scratch, of course).

@Gaia
Why can't you make backups of an XCD?

I'll try the CoreVorbis direct show filter and see if that works.

The file has the same playback problems when played from the hard drive.

I can make backups of VCD so why not XCD? After all it is relatively the same thing. And only AVI is at real risk of screwing the pooch with a single scratch. MPEG, RM, ASF, Ogg, OGM, and even Matroska should be very playable even if heavily dammaged. Though I have never tested it with Matroska myself. I am lucky enough to own a DVD burner. :D

It's Mode2 Form2 and it has been around for almost a decade or more. There is not much development left to do on it. ;)

I backed up a movie in Matroska container with 2 x 128 kBit 5.1 AAC sound, subtitles and XviD move onto XCD some days ago. The movie plays without any problems. I just think it is best solution to use Gabest's cdxasrc-Filter instead of the XCD one. That's just my opinion. MPC uses that player internally, so I didn't find any problem so far.

XCDs have 'only' 2 layers of correction, like audio and video cds, while normal Mode 1 CD-ROMs have 3 layers.

I really have no idea why people think that xcd has no error correction. Not long ago I had to explain the very same thing on http://www.videolol.com/mkv/phpBB2/index.php, before that also on cdfreaks and brennmeister...

even though you used mpc... install the xcd-ds_filter and try it again

I installed the CoreVorbis direct show filter and ran (the latest version of) MPC and I am still having problems. Maybe I need to reboot or change a setting in MPC?

Maybe I'll try the other route and the TCMP guys to support audio tracks & chapters for MKV XCDs.

Does Gabest XCD filter (that built into mpc) support buffering?
