Matroska with MPEG-1 streams...

[DanielSB]

Hello hello :)

Being a long-time user of VirtualDub and -Mod, I was thinking that it might be possible to do a direct stream copy of an MPEG-1 source to a Matroska output file, thus making it easy to edit losslessly.

VirtualDubMod will write the Matroska file like this, but under Compression in the save as dialog it says, "(No recompression: ÿÿÿÿ)", and of course "ÿÿÿÿ" is not a four-cc code that MPC likes.

At the Matroska site there's a list of codes for streams where MPEG-1 SE streams are "MPEG_1", but obviously that's not a four-cc code. But then again, AFAIK four-cc is AVI only?

So what does this mean? Is it just a small detail that can be fixed by using some sort of four-cc changer like the one Nic provides in the XviD package, or is the Matroska file total garbage?

Alternatively, and this is off-topic, can anyone recommend a tool for cutting stuff out of an MPEG-1 stream and saving it without recompression à la VD's direct stream copy?

TIA,
Daniel :)

MPEG1/2 in Matroska will not work in VDM

if you want to cut MPEG1 streams use TMPGEnc.

TMPGEnc? I had no idea. Thank you :) Is it usable? I mean, is there proper navigation, previewing, that kind of stuff?

On an off-note, has VDM development ceased? And I'd be right to assume that the reason MPEG-1 streams don't work in Matroska files is strictly an issue with VDM and not Matroska, right?

Cheers,
Daniel

Yes (file-->mpeg tools, "merge and cut"tab)

Yes

Yes (its a problem with any old parser)

Okay, cool. Except for the VDM part, that's sad :'(

Thanks for the help :)
