Audio bitstream (IEC 61937) implementation on radeon

Discussion created by albain on Oct 4, 2009


I don't know where to post this topic so I post here

I am a directshow developer, and I am looking for implementation details of audio bitstream.


The new radeon 5xxx are announced as supporting HD audio bitstream, including : Dolby True HD/MLP, DTS HD, AAC,WMA Pro


Microsoft brought some standards encapsulation in windows 7 (see

But this only applies to windows 7

My question is : does your driver follow this implementation for new radeon 5xxx (and also maybe for radeon 4xxx) or is there another approach ?

Can you give details ?

For example commercial players such as arcsoft has brought this bitstream support to their software on your new HD5xxx series and for all operating systems.


I am looking forward to get some details about this


Thank you
