    214Hardware Accelerated Codecs utilize the IMX Video Processing Unit (VPU) hardware block and can provide encoding and decoding various formats with very little CPU overhead in some cases. These codecs are made possible by a combination of:
    22 </p>
    23 <ul><li>proprietary closed-source binary VPU firmware from Freescale
    24 </li><li>various software packages that implement the VPU API

    3313The standard BSP distribution supports the following codecs:
    34 </p>
    35 <ul><li>Audio (Software codecs):
    36 <ul><li>decoders: AAC, MP3, Vorbis, FLAC
    37 </li><li>encoders: SBC, MP3
    38 </li></ul></li><li>Video (Hardware codecs):
    39 <ul><li>decoders: MPEG-4 ASP, XVID, H.264 HP, H.263, MPEG-2 MP, MJPEG BP, VP8, Sorenson-H263
    40 </li><li>encoders: MPEG-4 SP, H.264 BP, H.263, MJPEG BP
    41 </li></ul></li><li>Speech codecs: G.723.1 G.726, G.711, G.728AB, NB/WB AMR
    42 </li><li>Image codecs (Hardware codecs): JPEG, BMP, GIF, PNG
    43 </li></ul><p>
    44 In addition to the above, an AACPlus audio decoder is also freely available from Freescale but can not be included in our BSP because Freescale needs to track the number of downloads to comply with their licensing terms. You can extract the AACPlus codec from the <tt>L3.10.53_1.1.0_AACP_CODECS</tt> download available from from freescale.com

    6338Distribution is done via Freescale's controlled access extranet and requires agreement to be in place with Microsoft, Dolby or Rovi for the specific technology prior to accessing in order to comply with these parties requirements. Once customer is given access to a codec all silicon is considered 'enabled' and may require reporting obligations to the third party technology owner per the customers specific license agreement with the third party.
