OMAP L138 Video codec using VPIF

Mark,

We strongly recommend that you start a new thread with the issue that you have so that it can be tracked by the engineering teams. I am going to split the thread to start a new thread for you.

Hello again,

I'm using codec lib for c64+. The project is building, go to the  ALG_create(IALG_Fxns *fxns, IALG_Handle p, IALG_Params *params) function. Then I go to algAlloc() function and I receive   Interrupt Handler.  In ialg.h I have:

Int (*algAlloc)(const IALG_Params *params,
struct IALG_Fxns **parentFxns, IALG_MemRec *memTab);

and nothing else.  Where is the body of this function or what should I do ?

Regards,

Mark Duda,

What is the version of package are you using for codec lib?
Refer the user guide for that particular package or software.

Hello,

I use: 

codec_engine_3_23_00_07

xdais_7_24_00_04 (or xdais_7_21_01_07)

bios_6_34_02_18

c64xplus_mpeg4enc_02_02_04_production

framework_components_3_24_00_09 (or framework_components_2_20_01)

LCDK Omapl138

Okay, the main question is: have I write this function myself or it is somewhere and I don't have to do this? I installed older versions of codec, bios, framework like in documents to codec lib examples and this doesn't work. 

Kind regards,

Mark Duda,
You do not write that function, might be it was in library.
Please kindly verify the C64x+ codec lib can use for OMAPL138

I'm pretty sure it can be use, but maybe somebody from TI should confirm that. Is there only examples for ccs 3? Maybe I find for ccs 5.3 without converting?

Mark Duda,
I can suggest you, refer dvsdk release guide and get this package.
You can use the DSP Optimized codec from Multimedia Package.

Thank you, but I don't want to use linux, I want to use this library with sys/bios without it. Has anybody done this thing?

I have this warning: Product 'Framework Components' v3.20.0.22 defines no repositories. Uninstall and reinstall the product, or contact the product provider.

I have 2 other versions and this same warning. Maybe this is the problem?

Update: not only algAlloc function causes InterruptDefaultHandler but all from ialg.h (algAlloc,algInit...), I give mp4venc_ti.l64P library to linker.

I can see that nobody will help me here...

Refer this below thread,

TI is not providing CCS based video codec examples for OMAPL138/C6748. 

I know that you don't have examples, but I want to know if is it possible to do it on omap L138? I don't want waste my time. Is there in TI someone who can answer that or not?

Mark Duda,

Thanks for your understanding and also please kindly go through my first reply for your query.
Yes, Implementation of MPEG-4 video codec on OMAPL138 is possible.
However TI provides video codec examples with some limitation of DVSDK for OMAPL138.

Okay, but I don't use Linux. I use ccs 5.3 and I dowloaded c64+ codec library with example mpeg4enc and mpeg4dec. I build my project but something is wrong when it is running. Can I use this lib from ccs?

This codec can be used on any of TI’s C64x+ based platforms.
Please kindly refer the below links for get more details
http://www.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=sprab73
http://www.ti.com/lit/an/sprab73/sprab73.pdf
This codec supports all of which have TMS320C64x+ DSP cores. Refer the release notes from the installed path mention as below,
c64xplus_mpeg4enc_02_02_04_production\packages\ti\sdo\codecs\mpeg4enc\docs\MPEG4_Encoder_ReleaseNotes.pdf

Okay,

So according to this;http://www.compandent.com/, C674x is based on c64x+, so I can implement this lib on Omap L138? Is C674x really based on c64x+? I tried to implement this library on Omap L138 earlier and something was wrong. Thats why I ask you.

Mark Duda,

Yes, The C674x DSP core is code-compatible with the C6000™ DSP platform and supports features of both the C64x+ and C67x+ DSP families.

You can implement that video lib on OMAPL138. And also maybe you will get compile error and solve that yourself.

Pubesh,

I need support with this library, I have some questions, can you answer that or somebody else from TI?

My situation: I downloaded c64x+ library for mpeg4. I imported this project (ccs 3.3) to ccs 5.3. My first question: how th cfg file should look like? I have there:

var MPEG4ENC = xdc.useModule('ti.sdo.codecs.mpeg4enc.ce.MPEG4ENC');

var Engine = xdc.useModule('ti.sdo.ce.Engine');

var FCEngine = Engine.create("encode", [{name: "mpeg4enc", mod: MPEG4ENC, local: true, groupId: 1},]);

xdc.loadPackage("ti.sdo.ce.video");

Should I write myself functions:

algAlloc(), algInit(), control(), process()? This is importatn because I program crash when I try to call these functions.

Mark Duda,

Please kindly refer the BIOS guide from install directory \bios_6_xx_xx_xx\docs
Bios_Legacy_App_Note.pdf
Bios_User_Guide.pdf

You can find the source of alg functions from the below path
c64xplus_mpeg4enc_02_02_04_production\packages\ti\sdo\codecs\mpeg4enc\app\Client\Build\TestAppEncoder.pjt
c64xplus_mpeg4enc_02_02_04_production\packages\ti\sdo\codecs\mpeg4enc\app\Client\Test\Src

I would recommend create new theard, because it has Verified Answer flag.
Personally, when I am looking for posts to read and help with, I ignore those that have been answered.
Others may do the same.

And also if you have query about .cfg (BIOS), post to BIOS forum. Maybe you can get fast reponse for that.
