OMX DEI component concatenation

This issue is important for me too, can anybody answer this question please? 

Gabi / Alla,

How many buffers you have allocated for display ? You can try using SC5 instead fo DEI->DEI to isolate the issue. On DM8168 there are two DEIs DEIH and DEIM, so you can try using these as well.

Vimal

Hi VImal,

Thanks for your reply, i am using DEIH because i am working with HD input, i have used 5 buffers for the display.
I am using DEI because i intend to use capture in 422 format and DEI can scale up/down in 422 format and SC5 can't.

Is it possible at all to use 2 DEIH in concatenation?

Gabi 

Gabi,

I assume you have created two handle for DEIH. DEI driver support max 4 instances, so It should be possible to use them in tandem. Also DEIH and DEIM both can handle HD 420 inputs. So you can use DEIM as well. SC5 can take 422 or 420  input, o/p is however always 422.

Regards

Vimal

Hi Vimal,

Now that we know that it is possible to connect two DEIH in tandem, and we know that it should be possible to create the following OMX chain:

capture(420)->DEI(out in 420)->DEI(out in 422)->display,

We also know that i have used 5 buffers for display.
Why is my OMX example stuck?

Can you please help me debug this example?

Thanks,
Gabi 

Gabi,

Probably we will need to debug one step at a time. Have you tried only one DEIH(scale down) and get it functional in capture-DEI-Display chain ? If that works, we can try same single DEI chain with (scale up) parameters, to make sure parameters are right and it works. Now we can try DEI-H and DEI-M, as these will two difefrent component, to try if chain works, then we can try using same DEI(H or M) in tandem.

Also please see detail o/p from media controller by running

./loggerSMDump.out 0x9e400000 0x100000 video/vpss/all

Regards

Vimal

Hi Vimal,

I took your advice and replaced one of the DEIH with DEIM and the example is working OK now, i tried to use two DEIM and it is also working OK. 2 DEIH continue to stuck.
Is there any known problem with DEIH? 

Gabi

Gabi,

There is no known issue with above configuration (atleast I am not aware of any). OMX component is same for both drivers. I will check internally if any such limitation exists. Meanwhile, It will help if you could pass on DEI-H parameters, to see if there is any limitation.

Regards

Vimal

Hi Vimal,

Please see below the parameters for DEI scale down and DEI scale up.

Gabi,

Is it failing in creation ? DEI-H may use more memory so creation can fails if it runs out  of memory. Since DEIM-DEIM is functional, DEI-H is also expected to be functional.

Please provide "loggerSMDump.out 0x9e400000 0x100000 vpss" details also.

Regards

Vimal

Vimal,

The example fails during running, i can see a few frames and then it stuck. You can build similar example and see for yourself.
I can't get any data from the loggerSMDump.out, i think it is because i am working with Z3 board and i received the VPSS compiled from them probably in release mode.

Gabi,

I will try to reproduce that here. We had seen an issue where DEI does not give nFiledLen value properly. That is required to get proper chroma pointer in buffer. Could you please check this for DEI. 420 O/P of DEI should have nFilledLen as wxhx3/2, and offset as zero. I am not sure which version Z3 is using. for older version

./loggerSMDump.out 0x9e100000/0x9e400000 vpss  should work.

Vimal,

All the parameters for both DEI components are OK because in DEIM it works perfectly. It stuck only with DEIH.

I am working with EZSDK 5.02 thus logger_sm address is 0x9e400000 as seen in http://processors.wiki.ti.com/index.php/EZSDK_Memory_Map and also can be seen in MemSegmentDefinition.xs, after i have followed carefully the instructions written here http://processors.wiki.ti.com/index.php/OMX_Viewing_Media_Controller_Traces#Version_Information_and_Compatibility i couldn't get this loggerSMDump.out work properly, the log file is created empty. Can this loggerSMDump.out work if the HDVPSS firmware is compiled in release mode?

Gabi

Gabi,

loggerSM would work in release mode also. In fact EZSDK supplied binaries are not debug mode, but logs can be seen.

Hi Vimal,

Thanks for your answer, now that i know for sure that the loggerSM need to work, what is the reason that  logs can't be sean?

Gabi

Hi Gabi:

     I have not see how do you resolve the problem?Are you resolve?

   Thanks !

The problem is resolved, i have used DEIM instead of DEIH, TI has probably a bug in DEIH.

Gabi,

For DEI-H to DEI-H connection did you try without any scaling ? does it gets stuck ? I tried DEI-H to DEI-H and it is functional and does not stuck.

Vimal

Hi Vimal,

Thanks for your answer, i can't remember if i have checked it without scaling, but if it is working without scaling and stuck with scaling isn't it also a problem?
Please check with scale down in the first DEI and scale up in the second DEI, i have sent you the parameters in this thread.

Thanks,
Gabi 

Gabi,

I am doing upscaling and downscaling, and It seems to be running fine. I have both DEI inputs as 420SPYUV as you wrote in your first post . However I see the code you are using 420 for one and 422 for another DEI ?  what is exact configuration ? 

Regards

Vimal

Hi Vimal,

The first DEI input is 420SPYUV 1080P and the output of first DEI is 422YUV scaled down by 4 horizontally and 4 vertically, the second DEI input is 422YUV in the same size as the first DEI output and the second DEI output is 422YUV original size (sent to the display). 

Thanks,
Gabi
