Hi,
We have a customer looking for MPEG1, Layer 2 audio encoders for the AM3517 that are optimized for the NEON co-processor. I pointed them to the FFMPEG encoders (ffenc_mp2 in particluar).
The customer doesn't believe these use NEON, can someone please clarify?
As I read this from (http://processors.wiki.ti.com/index.php/ARM_Multimedia_Users_Guide), I think they are NEON optimized:
“Open Source FFMpeg Codecs
FFmpeg is an open source project which provides a
cross platform multimedia solution.

provides 1.6x-2.5x performance on complex video codecs
Can someone clarify whether these codecs are NEON optimized? If they aren't, is there a source for MPEG1, Layer2 audio encoders that are? Thank you very much?
