VS1063 encoder MPEG-1 Audio Layer II

Post by DVL_engineer » Sat 2013-08-17 11:59

Hello to all!
Please help me. This microcircuit (VS1063) doesn't support encoding MPEG-1 Audio Layer II. My company have bought 100+ of this chip. So where I can find User's application for encoding audio stream to MPEG-1 Audio Layer II of course if this code exist.
In the discussion invited experts.

Hmmm... MP2 requires different licenses than MP3 so we have not written the code to encode MP2. I don't know, maybe we could write such a code, although it would probably take many months. Is there some other format that you could perhaps use?

Thanks for the reply!
We need to transfer embedded audio stream how a part of data stream (video signal). To resolve this problem we need to use only MPEG-1 Audio Layer II. For the decoding audio stream the VS1063 is suitable, but for encoding, alas, it is not suitable.
So can you say me the analogues of VS1063 who can decode or encode the MPEG-1 Audio Layer II? I can't find in the i-net.
I will be grateful to you!

Hi!

It seems we have no current plans to implement MP2 encoder.

I don't know... maybe you could configure a small linux box such as Raspberry Pi (http://en.wikipedia.org/wiki/Raspberry_Pi) to encode MP2?

Hello!
Good idea, but for my company not suitable. We need a microcircuit such as VS1063.
Well, thanks a lot for help. If you have any other ideas, please keep me informed.

Hi DVL Engineer,

Do you have any solution on Mp2 encoder found? I am also interested.

I do not think microcircuit such as VS1063 is supported by VS1063 encoder. I have read this in the VSDSP blog and you can contact the technical support team to know more about this. I do not know whether this feature is included recently or not.

Sorry,
VS1053 or VS1063 supports MPEG-1 Audio Layer II DECODING?? I want to use this only for decode MPEG-1 Audio Layer II, MP3, and AAC.
Unfortunatelly I haven't found in the documentation any info about MPEG1 Layer II decoding... anyone can confirm that this family can decode this format.

VS1053b and VS1063a include the MPEG-1 Layer II decoder. You need to enable the decoding by setting the LAYERII bit in the SCI_MODE register. This is because some claimed patents on Layer II (search for Sisvel). If you have agreement (for example due to layer II encoding) that covers those, you can just set the bit to allow layer II decoding. (The mp3 license is included in our chip prices.)

I'm not sure whether those MPEG-1 layer II patents have expired already. (They should have by now, as far as I know.)

All of the remaining mp3 patents should expire for certain next year if I remember correctly.
