RTOS/TDA2: tidl_OD Usecase error

Surendar V B

Part Number: TDA2

Tool/software: TI-RTOS

Hi Everyone,

I am trying to run "TIDL OD usecase" on VSDK 3.4 , I believe the following bin files are required for the successful execution of usecase

> TIDL OD Network file (NET_OD.bin)
> TIDL OD Parameter file (PRM_OD.bin)
> TIDL OD Usecase input data file (inData_OD)
> TIDL OD Usecase input header file (inHeader_OD)

For the network file and parameter file I have copied below files from the path , vision_sdk\apps\tools\TIDL_files\

> tidl_net_jdetNet_ssd.bin

> tidl_param_jdetNet_ssd.bin

For the Use case input data , I have downloaded the clip files from CDDS (currently trying with clip2.avi under single_cam_video_input_clips) and followed the below procedure to generate header file and data file

1) inData_OD generation

> ffmpeg -i clip2.avi -y -c:v libx264 -vframes 50 inData_OD

2) inHeader_OD generation

>ffprobe -show_packets ./inData_OD >index.idx

>PAT=size

>sed -n "/$PAT/p" index.idx | cut -d' ' -f3 >> size_extracted.txt

After this step, size_extracted.txt will contain size of the frames. Remove the string "size=" from each line in the file and save only the numbers in size_extracted_jelly.txt.

>cat size_extracted_jelly.txt | perl -n -e 'printf("%08x\n",$_)' | sed 's/$..$$..$$..$$..$/0x\4\n0x\3\n0x\2\n0x\1/' | xxd -r -p > Size_test.bin && du -b Size_test.bin

>cp Size_test.bin inHeader_OD

I have also copied the respective text file with below details

TIDL Configuration parameters
-----------------------------

inputWidth=736
inputHeight=320
inputFile=inData_OD
inputHDRFile=inHeader_OD
netFileName=tidl_net_jdetNet_ssd.bin
paramFileName=tidl_param_jdetNet_ssd.bin
fps=30
threshold=0.3

However , I am getting following error while running the usecase

DECODE: ERROR: ALGPROCESS FAILED (status=0x20208001) !!!
DEC_LINK: outArgs->viddec3OutArgs.extendedError for channel 0 Error: 0x20208001
DEC_LINK: Sequence called number 1

Kindly help me on resolving this issue . I have tried same for Semantic segmentation usecase with net and param bin files from the path /ti_components/algorithms/REL.TIDL.01.01.01.00/modules/ti_dl/test/testvecs/config/tidl_models/jsegnet21/ but i got the same error.

I have referred below forum links for it

Hi Surendra,
Could you please verify inputWidth & inputHeight of the file you generated is same as you are passing in .txt file ?
TIDL inData_OD & inHeader_OD file also available in CDDS
Could you please download & verify with that ?
cdds.ext.ti.com/.../emxNavigator.jsp

Surya

Hi Surya,

I have used input files from the same CDDS link which you mentioned only , I am using single cam video input files for my testing .
I have performed the steps I mentioned before to create the inData and inHeader files . I couldn't find inHeader_OD files in the link so I have generated it .

In .txt file I have metioned the width and height as 736 & 320 respectively . The resolution of the video is 1920x1080 will that cause issue .

Surendar

Hi Surya ,

I have fousnd inHeader and inData under xcam folder , I am not sure whether that is the file you are mentioning about . Anyway I have renamed both as inHeader_OD and inData_OD and copied into SD card .

When I ran the tidl_OD usecase I am getting the following error :

Assertion @ Line: 220 in nullSrcLink_tsk.c: frameLength < bitstreamBuf->bufSize : failed !!!

Hi Anuj ,
I have downloaded the files from the link you mentioned only , I am using clips under "single cam video input" .
I am maintaining the resolution of the video in txt file as 736x320 , if I change that to 1920 x 1080 which is resolution of the clips given in the link , assertion is throwing out as below

Set DSS parameter failed
[IPU1-0] 26.733910 s: Assertion @ Line: 459 in displayLink_drv.c: status==SYSTEM_LINK_STATUS_SOK : failed !!!
[IPU1-0] 26.734398 s: Assertion @ Line: 459 in displayLink_drv.c: status==SYSTEM_LINK_STATUS_SOK : failed !!!

Kindly help me in sorting out this issue

Hi Anuj,

I have used the files from the following path , please verify it is wrong or not :

VISION_SDK_02.XX.XX.XX_INPUTS -> single_cam_video_input_clips -> clip2.avi

I have used clip2.avi as inData_OD and also created inHeader_OD using this .

Kindly guide me on this

Yes. This is wrong.
You are searching in wrong folder.there will be a TIDl_files folder.
In That folder you will find inData_OD.
You do not need to rename any file.
