I've written them, let's see if they have time to answer. Yes, I wouldn't mind at all, but I think the GPL minds this kind of giving credits. BTW, doing some research I've found two other applications with source available, which deal with DDP, from reading the source I'd guess they had access to the spec, but it's hard to tell for sure. "dvdtape" is GPL, and "XLD" (for MAC OSX) should be GPL, because it uses tons of GPL libraries (together with other code), but it's own license I can't find. Both software does not mention any "licensed from DCA" stuff. That's what I though I'm doing for now. If I add support for reading cue sheets from stdin, then Ardour or any software could just pipe into it to create DDPs, if they wanted. Sort of like the low tech plug-in interface. But could Ardour even optionally link to a non-free library? Have you tried "dvdtape"? I believe it writes a DDP 2.00 on tape from an ISO image, could be exactly what you are looking for. It's in the repositories. Regards Andreas

You're probably right. I few years ago I had a conversation with them, and surprisingly enough, they didn't have much of a clue about open source in general and the issues they were concerned about (like me potentially helping their competitors, or the existence of code which would not implement the spec correctly) were not something their license would be able to prevent. So it was kind of strange conversation, and very little helpful. Ah, that's interesting to hear, I thought those 8mm tapes were history since at least 6 years and officially discontinued even longer. But I just checked with Arvato Digital Services, one of the biggest manufacturers in Germany and they still accept Exabyte. I've send many masters out in that format, but since roughly 6 years, I completely switched to DDP on DVD-R, which has always worked fine (with the exception of NAXOS, who I think replicated once from the reference CD copy...). Are you sure, the plants in your area do not accept DDP on other media like hard disk, USB stick, or DVD-R? For FTP I think DDP us preferred anyway. That said, with the code from dvdtape as an example of how to properly write to tape (Exabyte will probably work very similar to DLT I guess), it should be possible to add tape output to cue2ddp, I just wonder if it's worth the time. And while I have plenty of those media around, I don't have a drive for testing over here these days. My impression is, that interest in DDP is extremely low among Linux audio people, so for DDP on tape you may well be the only person on this planet lookin for that--not saying that's a bad thing, though. ;) Thank you, Raphael, I'll keep that in mind!
