hi, Sivaramkrishna 

i'm facing with the same issue on our target board, i just want to know if you get your problem solved.

regards, Mike

Thanks.

Does CE_DEBUG=3 generate any additional trace? Are you able build your application with 'debug' profile components and step into the VISA create function? If you have the algorithm package source you may also want to put a breakpoint in its algorithm IALG::algAlloc function. (external symbols should be published with the algorithm documentation).

A creation error would likely be due to running out of a system resource (memory, dma channels, vicp, ... ) perhaps posting relevant information of your application configuration might have some clues.

Best regards,

Murat

Hi, Murat.

Thanks for you post.

this is what i have done :

status = VIDDEC2_process(pvideodec->hDecoder, &inBufs, &outBufs, &inArgs, &outArgs);
status Failed with -1 and getlastererror: 0

printf("decodedBufs.extendedError 0x%x\n" , (int)outArgs.decodedBufs.extendedError);
decodedBufs.extendedError return with  0x0

with CE_DEBUG=3 i get

any ideas ????

thanks in advance.

Hi Mike,

It looks like you are farther along, past the 'create' phase, and now bumping into issues as to how to use the codec. (Curious what the issue was with creation before.)

Your trace here shows that as far as Codec Engine is concerned everything went as expected. However, your decoder has returned -1, which is a general non-specific failure.

This could be due to a lot of codec specific reasons, so you will have to ensure that you have created the codec with the supported creation parameters, and are passing everything as expected by the codec's process() function. These include the sizes of the inBufs and outBufs, and the other attributes of the inArgs and outArgs. I am not a codec expert, so you would need to rely on documentation about the codec.

You may also want to check the 'extendedError' fields of the  outArgs after the process() function returns, to see if there is any more specific error information.

Best regards,

Murat

hi, Murat.

Thanks very much.

it was found out that if the app is running not in the script but the active shell, the timeout message gone:

Entered SemMP_pend> sem[0x335c28] timeout[0xffffffff].

I have checked "extendedError"

i don't know why if CE_DEBUG=2/3 is set, i get none zero value with the "extendedError" or else it was always 0. 

Regards, Mike.

thanks again.

hi, Murat.

now i get  extendedError of 0x40211620

the LSB 0x20 tell us that the error is :

IH264VDEC_EX_ERR_FRAME_NUM_ERROR

which tell me that Error in frame number.

what's that referring to ???

i'm reading the 264 file form sps, pps, and I form the beginning.

any coments will be thankfull.

regards, Mike

Thanks.

I am not familiar with the codec specifics or the extended error code you are observing. My advice is to read up on the documentation and check your usage.

Perhaps someone in the community with better insight might reply.
