Hi all,
I have solved this problem by modifing
dvsdk_2_10_01_18/dmai_1_21_00_10/packages/package.xs,
change:
var codecInterfaces = [
"ti.sdo.ce.speech",
"ti.sdo.ce.speech1",
"ti.sdo.ce.audio",
"ti.sdo.ce.audio1",
"ittiam.extensions.audio1", /*For AAC,MP3 and WMA */
/*"ittiam.extensions.speech1", *//* For G711 */
"ittiam.extensions.common", /* For AEC */
"ti.sdo.ce.video",
"ti.sdo.ce.video1",
"ti.sdo.ce.video2",
"ti.sdo.ce.image",
"ti.sdo.ce.image1",
];
to:
var codecInterfaces = [
"ti.sdo.ce.speech",
"ti.sdo.ce.speech1",
"ti.sdo.ce.audio",
"ti.sdo.ce.audio1",
"ittiam.codecs.aaclc_enc", /*For AAC */
/*"ittiam.extensions.speech1", *//* For G711 */
"ittiam.extensions.common", /* For AEC */
"ti.sdo.ce.video",
"ti.sdo.ce.video1",
"ti.sdo.ce.video2",
"ti.sdo.ce.image",
"ti.sdo.ce.image1",
];
and I think wiki page:
http://processors.wiki.ti.com/index.php/DM365_Audio_Codecs_Integration_with_DVSDK_2.10.01.18_Demos
should also be updated becuase it's wrong for current version of audio codec.

Unable to locate alg "aacenc".
Thanks Ring,Chris for help.
The CE debug info is as below:

audioThrFxn(): Failed to create audio encoder: aacenc
and as I see, the problem is Unable to locate alg "aacenc".
I'm a little confused, because the codec package of version 2.8.0 has 3
directorys:
app, codecs, extensions
but version 3.5.0 only has app and codec directories, no extensions directory,
so I use the old version instead, and I think they should be the same.
I download AACLC encode 3.5.00 from page:
http://software-dl.ti.com/dsps/dsps_public_sw/codecs/DM365/index_FDS.html
becuase I use dmai interface for appication, so I locate aacenc v2.8.0 by
adding "ittiam.extensions.audio1" in file:
dvsdk_2_10_01_18/dmai_1_21_00_10/packages/package.xs,
as below:
var codecInterfaces = [
"ti.sdo.ce.speech",
"ti.sdo.ce.speech1",
"ti.sdo.ce.audio",
"ti.sdo.ce.audio1",
"ittiam.extensions.audio1", /*For AAC,MP3 and WMA */
/*"ittiam.extensions.speech1", *//* For G711 */
"ittiam.extensions.common", /* For AEC */
"ti.sdo.ce.video",
"ti.sdo.ce.video1",
"ti.sdo.ce.video2",
"ti.sdo.ce.image",
"ti.sdo.ce.image1",
];
it works for version v2.8.0 but does not work for v3.5.0 becuase v3.5.0 have no
extension directory within codec package.
maybe we can use another way to integrate aac codec without extension directory?

Just as an example of what this might be - the newer codec _may_ require more
resources than before (e.g. DMA channels), and if those extra resources aren't
made available (typically done in the .cfg script), the creation may fail.
You may be able to learn more about the exact cause of the create failure by:
1. Enabling trace in Framework Components
(http://processors.wiki.ti.com/index.php/Trace_in_Framework_Components)
2. Displaying that trace via CE_DEBUG
(http://processors.wiki.ti.com/index.php/CE_DEBUG)
You might also dig through the codec data sheets and/or users guide. Sometimes
those show what resource requirements the codecs have - you might get lucky and
find differences there, too.

Subject: dm365: problem when aacenc update from version 2.8.0 to 3.5.0
Hi all,
I'm use dvsdk_2_10_01_18 and update framework_component to 2_25_00_04 and
linuxutils to 2_24_03,
when I use aac audio codec v2.8.0, everything is ok, but when I update it to
v3.5.0, with same paramters to open audio codec, it does not work.
that's, Aenc1_create() return NULL,.
If anybody has solved or encounterd this problem, please help me.
thank you very much.
