Ticket Name: RTOS/TDA2: tidl_OD Usecase error

Query Text:
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

Responses:
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 Regards 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 . Regards, 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 !!! Regards, Surendar

Hi, The difference in resolution will cause issue. You can find the files in below link cdds.ext.ti.com/.../emxNavigator.jsp Regards, Anuj

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 & Surya, Is there any update on this Regards, V.B.Surendar

Hi, Please check for the correct files in that link. You are using wrong files. Regards, Anuj

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 Regards , Surendar

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. Regards, Anuj

Hi Anuj , Thank you , it is working as you said the files are wrong Regards, surendar
