RE: Maxim's Atrac3plus decoder
Hi guys (and girlz),

my ATRAC3+ decoder has finally been posted to the FFmpeg project.

You can either follow up on our discussion here:
http://ffmpeg.org/pipermail/ffmpeg-devel...49248.html

or grab the latest Git snapshot, apply the above-mentioned patches and start to experiment with the decoder yourself.

Enjoy!
Best regards
Maxim

I'm pleased to hear that!

At the time being, you're running a scalar version of the decoder. Its speed can be increased by 15-20% by vectorizing several DSP functions.

Most modern CPUs include some kind of SIMD/Vector instructions in order to improve the performance of multimedia applications...

IIRC, Xuggler is just a Java wrapper for FFmpeg, isn't?
What do you need for Xuggler being able to decode ATRAC3+? A custom FFmpeg build?

Best regards
Maxim

Pretty much, yes. However, I believe it should be possible to implement the changes directly in Xuggler's source code and build the whole framework at the same time (Xuggler + FFmpeg) with little trouble.
I've been looking into this and since Xuggler is built on top of FFmpeg's code it should be just a matter of updating the FFmpeg captive files first ( https://github.com/artclarke/xuggle-xugg...er/captive ) and then manually add the new codec's info to the source code ( https://github.com/artclarke/xuggle-xugg...r/ICodec.h ) and apply all the necessary changes afterwards.

I'll try forking Xuggler and merge the latest FFmpeg snapshot and your patch to see what I can come up with.

Good luck with the review, Maxim. Smile

Regards,
Hykem

RE: Maxim's Atrac3plus decoder
Really great news here! I take the opportunity to thank you Maxim for all your hard work and sorry for doubting you in the first place, hope we can have this implemented on PPSSPP in the near future...I will patiently await from now on

Does anybody want to share a build with the patches?

How it will work, by plugin or implemented in the PPSSPP? Smile What is the advantage besides being faster?

RE: Maxim's Atrac3plus decoder
Aside from being faster, the big advantage is that we don't need a plugin anymore, we just link ffmpeg as we already do.

RE: Maxim's Atrac3plus decoder
It will fix issues on ffmepg too or just on audio playback? Because I get issues in video playback on some games.

RE: Maxim's Atrac3plus decoder
I don't want to create a new thread for this question but i wonder, why hasn't anybody created a plugin for Winamp using the current MaiAT3PlusDecoder?

That decoder was out for a while and nobody never bothered to create a plugin for Winamp or any other music program out there.

[GPU]: EVGA GeForce GTX 970 Superclocked ACX 2.0 4GB GDDR5

[RAM]: Corsair Vengeance 16GB (2x8GB) DDR3 1600MHz
[MOBO]: MSI Z97-GAMING 5
[PC CASE]: ENERMAX Ostrog GT (Red)
[CPU FAN]: Cooler Master: Hyper 212 EVO

RE: Maxim's Atrac3plus decoder
Since ffmpeg now can now decode ATRAC3+ you can link your played to ffmpeg to decode those files with no extra plugin.

Indeed, but i was just wondering why nobody did a Winamp plugin with MaiAT3PlusDecoder since it was the only open source decoder to get music working when it came out months ago.

RE: Maxim's Atrac3plus decoder
because nobody in the dev community is caring about at3+ file?

Like maxim finished his work.. probably because he already had done a big part of it and was like: "meh I could at least finish it for psp emulator..."

ps.: srsly don't trust me, I'm saying shit right now.
