MP3 and AAC codecs may not be compiled with CCS v.4 shipped with eZDSP USB STICK

Thank you ,Chris.

I have purchased a TMS320VC5505 eZDSP USB STICK, but it was shipped with the new version CCS v 4.

On the TI web site, I haven't found the possibility to download CCS v3.3 for evaluation.

Do you have an idea where to find XDAIS v. 4?

I have the same dilemma as Fab.  I am trying to bring my employer on board as a TI customer.  I have selected TI's C55x DSP family because TI provides a COTS audio compressor algorithm that can be run on a cost-effective processor.

I, too, have bought an ezDSP USB STICK which shipped with CCSv4.  We have no recent history of TI DSP use, so I don't have a prior CCSv3 library on which to draw.  Your link to an explanation of the mechanism of the problem does not offer me a solution to it.  Its statement that "System integrators are recommended to use the Codec Engine framework, or DSKT2" doesn't at all help me as a system integrator trying to employ an algorithm developed under a different standard.  My goal here is plug-and-play.

The E2E Community page on which TI announced the availablility of codecs for the C55x (http://e2e.ti.com/support/dsp/tms320c5000_power-efficient_dsps/f/109/p/10973/42714.aspx#42714) is dated less than a year ago, so these don't seem to be stale products.  [I notice that another customer who asked about licensing arrangements on that page never received a public answer.]  The "PRODUCT PREVIEW" for the AAC Encoder (http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C55X_Audio/C55X_Audio_latest//MPEG4AAC_LC_Encoder_C55x_Datasheet_1_00_00_03.pdf) is dated just 8 months ago and the date of the actual library file aar_tni_rev2.l55l I downloaded is just 7 months ago.

Will TI be bringing this apparently new product up to date for their current tool set, or at least provide us newcomers with resources to utilize them together?

Please help me out here,

Dan

Come to think of it, are these old CCSv3 / XDIAS 4 files actually needed to employ the AAC Encoder algorithm, or are they just necessary to build the demo program that comes with it?  Can I use the demo code as a template and just incorporate the aar_tni.h include file and the aar_tni_rev2.l55l library file in my design?

Dan

CCSv3/XDAIS are required ot build sample test application only. Test harness release with codec package needs these header files. For actual end application, we can use the codec library along with codec interface header files.

OK, with a not-insignificant bit of massaging of the source code, I managed to get TestAppEncoder compiled and functional under CCS v4.  Much of it was a matter of replacing "ALG_" with "IALG_," but there were also some missing function prototypes that kept the code from compiling correctly and one function neglected to return a requisite value.  It would appear that this code was publicly posted without actually being debugged.  I also had to modify an #include search path that had one two many "../"s.

Below is a summary of the edits I made to get it operational (mostly shown as commented-out lines followed by their replacement).

Dear friends

I had the same problem, but now I can compile TI's free audio codec test software successfully on C5515 eZdsp USBStick. 

It seems my answer is too late, but I believe there are still  many friends in trouble, so I believe my post may help somebody.

Please look following site and download Free  MP3 Player  software.

http://www.elektor.com/magazines/2011/march/mp3-one-two-three.1706996.lynkx

It  includes XDAIS module, so you can add link path to it.

Also this software has a lot of useful examples.

I have downloaded this free MP3 player software from the above link and successfully compiled on C5515 eZdsp USBStick,but when I try to watch the CPU load it just has nothing.I wonder if you have the same question and do you konw how to solve it?

Thanks very much!

Hi my friend,

I have downloaded the free MP3 plyer software and can complie it successfully on C5515 eZdsp USBStick,I use CCS5.2 to build the project.

Now I want to watch the CPU load and count the decoding  time of per frame,but I can see nothing in the CPU load chart.Have you encountered the same problem?Thanks a lot!

Regards,

Chen
