RTOS/TDA2XX: analytics2 and null source decode issue

Josh HUANG

Hi all:

We are trying to run vip_single_cam_analytics2 usecase (from vision_sdk/apps/src/rtos/usecases) and source is from the null source decode.

We found display always freeze at about 3 min : xx sec.

But when system read end of video file and return to start, the display can rework, but it freeze at about 3 min : xx sec again(Loop this situation).

We change different video has the same status, so this is not video issue.

We modify chains_vipSingleCameraAnalytics2.txt => remove SFM and SOF flow then display does not freeze.

So this is CPU / EVE loading or memory leak issue???

Hi Josh

This demo is supposed to work well if you use & copy all input files correctly (which is shared in CDDS)

please check you copy "SFM_POSE.bin"

Hi Shiju:
The "SFM_POSE.bin" file was placed in boot folder of SD card, it's the same location as video , AppImage amd MLO.
Any other input file need to place to SD card?

The image source from camera capture is work, but from the null source decode(video) has freeze situation at about 3 min : xx sec.

Thanks for the details.

Are you using the same input file mentioned in user guide?

Please check with HDMI capture as input source, this is the validated configuration for this demo

Hi Shiju:

Sorry, My TDA2X board has not HDMI capture IC, so I can't test input source from HDMI capture.

But I had test input source from LVDS capture, it's work well and has not freeze situation.

Only when the source is from video file through the null source decode would be happen freeze in 3 min : 49 sec.

If test video file more than five minutes will be prone to this phenomenon but CUP/EVE loading stats display is alive.

Hi Josh
I guess the SD card is not able to sustain the data rate required for the usecase. We do have some sync logic inside the UC that can get mess-up if input is get delayed too much.
