Re: [linux-minidisc] linux-minidisc Digest, Vol 43, Issue 20

["Jurgen." <invictaz@yahoo.com>]

All good and well, but support in VLC (by the use of FFMPEG) of AT3+ is not yet ready. For the end user it is not possible to "just apply the patches to current FFMPEG release of october" and play with it. It seems so easy, but it isn't. And it won't happen anytime "soon". I saw the code, it's 5000 lines of pure C which is reviewed by only a handful of reviewers. Don't want to be pessimistic but I don't expect it before Q2 at least.

That is, if nothing comes in between. Maxim submitted the 4th revision of his code some days ago and probably some more versions will come. As every single line of code is evaluated, just like in this software it can take a long time.

Foobar runs fine under Linux via WineHQ though.

Yes, very old news. We were actually involved in the development
of this decoder. Michael did lots of the reverse engineering and
supported Maxim from ffmpeg with extra documentation.

Eh, it's been in ffmpeg for a while now, those guys probably ripped
it off ffmpeg and didn't credit them properly.

Here's the commit:

It will be part of the next ffmpeg release. Jean-Baptiste of VideoLAN
couldn't tell me, however, when it will be part of the official
VLC releases.

Thanks, but I don't use Windows ;). Anyway, it will be available in most
open source audio codec libraries very time soon, so it will be very
much operating-system-agnostic.

You might run into problems with foobar2000, however, since it probably
doesn't include the master key to decrypt encrypted ATRAC3+ .OMA
containers. Files transferred with QHiMDTransfer are not encrypted,
fortunately, but everything that you have previously backed up
with SonicStage is.

> So I'm going to try that because a VLC update will take a while I think :-)

Sure. But VLC will deliver the better overall experience in the end
unless foobar2000 has the universal .OMA decryptor included as well.

In addition: The decoder is also used in the PSP emulator named ?PPSSPP?. And it works brilliant.

I know. Guess who gave them the first source snapshots before
the codec was released ;).
