TDA4VM: TDA4 PSDK8.06

Hi Terry,

The four questions raised here are from 4 different domains.

I could give an initial response for all the 4 here. But I would suggest opening separate threads for each for faster response from respective experts.

And we could keep this thread for OpenVX only.

1. PSDK 8.06, how does openvx control the priority of nodes?

In OpenVX, the priority is based on the target on which the node is running. Target is nothing but a task running on a core. You could see the priority of each target in

${PSDKRA}/tiovx/source/platform/psdk_j7/rtos/tivx_target_config_r5f.c,

${PSDKRA}/tiovx/source/platform/psdk_j7/rtos/tivx_target_config_c66.c...

${PSDKRA}/tiovx/source/platform/psdk_j7/rtos/tivx_target_config_c7.c

2. PSDK 8.06. Does tidl support input in YUV format? Can we ask for a DEMO?

We do have yuv inputs for the TIDL demos. You could refer the vision_apps/apps/dl_demos/app_tidl_od/ and other file based demos for the same.

The flow would be as shown

3. Is there any note that we can pay attention to for porting from BIOS to freeRTOS?

I believe you are looking for the below

PSDK 8.06, when using the GST module for decoding, gst_app_sink_pull_sample returned status exception, do you have any troubleshooting ideas？

I would suggest running with GST_DEBUG = 3
