Audio decoding on i.MX6UL(6ULL) linux BSP

Dear community,

When an audio-only playback command is called on the i.MX6UL/ULL Linux GStreamer framework, is the corresponding audio decoding library performed on Cortex A7?
As you know, i.MX6UL/ULL has no AV codec hardware, I believe audio decoding should be done by software library, but I'd like to confirm about this.

Regarding audio decoding format, is AAC avalable on the software-library-based solution noted above, as well as MP3?

refer to the mx6UL Reference Manual, Audio codecs are provided by SW, which runs on ARM core, supporting
(but not limited to) MP3, WMA, AAC, HE-AAC and Pro10

Dear Joan,

Thank yoy for your reply.

Are these audio codecs, MP3/WMA/AAC/HE-AAC, supported on the BSP level?

In other words, are these codec SW libraries packaged in the reference BSP from NXP?  

I think so, but I'd like to confirm.

yes, can support it, but some codec like wma, aacplus, maybe you need license for them.

Dear Joan,

Thanks a lot.

Understand that i.MX6 UL/ULL BSP provides the audio codecs SW libraries.

Besides, noted surely some codecs force me to take the licenses.

in additional, mx6ul doesn't includes vpu, so coding by SW.
