RMAN_assignResources failed in H264 encoder init.

xiaobo li1

Depend on IPNC RDK 3.5 （attach to DM8127 Reference camera) ,I use H264 encoder as fellow:

HDVICP2_Init();
iresStatus = RMAN_init();
init_h264code_params();
H264ENC_create((H264ENC_Fxns *)&H264ENC_TI_IH264ENC,&gParams);
iresStatus = RMAN_assignResources((IALG_Handle)ghandle,&H264ENC_TI_IRES, -1);

RMAN_assignResources return failed. But I use JPEG encoder like this is ok.

I think there is error somewhere in .cfg file . I have View some documents about Framework Component,XDC. But I don't have any idea.

Hope the help!!

Hello,

RMAN_AssignResources fail in H.264 may be due to several reasons.

1. H264ENC_create() itself would have failed and therefore the ghandle could be NULL.

2. RMAN_AssignResources mainly has function calls like numResourceDescriptors, getResourceDescriptors, initResources. The memory requested by the algorithm via numResourceDescriptors and getResourceDescriptors should be provided by application else initResources functions returns FAIL.

For more information, please go through the docs H.264 user guide - H264_Encoder_HDVICP2_UserGuide.pdf and

http://processors.wiki.ti.com/index.php/Framework_Components_RMAN_Users_Guide and

Thanks.

Thanks for your reply,

In my program, H264ENC_create() was success and the ghandle isn't NULL.

I have see the docs (H264_Encoder_HDVICP2_UserGuide.pdf and Framework_Components_RMAN_Users_Guide). Because I'm newer of FC and H264 ，I'm not very clear.

I think what I should do is to write a ".cfg" file,and use APIs like the program you see above. I do not need to care the function call by RMAN_AssignResources.

1. Is this correct ??

2.If it's correct, I think there is some errors in my ".cfg" file. But I don.t know how to write a right ".cfg" file, because in <<H264_Encoder_HDVICP2_UserGuide.pdf >> I can.t find what resources H264 Encoder need and how to confige the resources in ".cfg" file.

Thanks,

Let's start with you enabling some trace so we get a better idea of where inside RMAN_assignResources, the error is occuring. See here for instructions on how to enable trace:-

http://processors.wiki.ti.com/index.php/Trace_in_Framework_Components

What version of Framework Components are you using ?

Did you start with an existing example from some sort of SDK ? I ask because I am not sure if your device (DM8127) is supported by some of the IVAHD specific modules in FC.

Hi,the version of Framework Components is:3.22.03.09 (which in IPNC RDK3.5)

We use h264 encoder ok in MCFW (in RDK 3.5).

1.Now my use environment is linux, not CCS. If I want to get the trace info,I must use CCS?

2.Is there a sample to demonstrate the H264 encoder on the RAMN API? (The demo in the encoder floder is not on RMAN API absolutely).

Thanks!
