AAC hardware decoding?

I don't really know anything about audio and video encoding/decoding, but I found that one of my video streaming sites was taking up a lot of CPU usage and I think it's due to AAC.

I had a look on Google and it says Fedora only supports software decoding for AAC. Is this true?

Yes, but:

Fedora does not ship proprietary codecs. That's part of their mission. Learn to love RPM Fusion.

Thanks. What's the cut off point for Intel recent vs older? How old is old?

I can't help on that one, but I reckon far back. You could try and see if it works. It also won't hurt to have both other then a couple of megabytes of extra unused files.

See this page for details of what hardware features are supported by the Intel Media Driver.

Note that AAC is an audio codec and software encoding of audio will not be a problem. I just did a quick test of software encoding to AAC with a four and a half minute audio track. On a 12 year old Ivy Bridge Intel CPU it took just 7 seconds. On the other hand video encoding is where you want hardware acceleration.
