Thanks Ring,Chris for help. The CE debug info is as below:

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? 2010-06-11 johnny 发件人： Ring, Chris 发送时间： 2010-06-11 01:34:26 收件人： johnny; Davinci-linux-open-source 抄送： 主题： RE: dm365: problem when aacenc update from version 2.8.0 to 3.5.0 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.

If anybody has solved or encounterd this problem, please help me. thank you very much. 2010-06-10 johnny
