PROCESSOR-SDK-J784S4: Implementation of encoding function for multiple camera (through separate tasks)

Hemraj Saurabh

Tool/software:

Hi Experts,

I'm trying to develop an encoding app, where the LDC output taken from graphs operating through separate tasks. A separate encoding task has been created for each LDC output (from each task), but this is not working properly. The app could encode the LDC input received from single tasks at a time. If multiple tasks ran together application got crashed.

Please help me to implement encoding functionality where separate tasks could create encoded videos for the LDC output received from the graph (from multitasking application). Tasks should run parallelly so that the encoded video for each task could be cratered parallelly.

The simple architecture of implementation is as depicted here:

Currently I'm using '09_01_00_06, version of sdk.

Hi Hemraj,

For the encoder, is there any reference that you used to create this wrapper and use the OpenVX buffer?

Hi Nikhil,

I am trying to develop the encoder application by the reference of demo Multi Cam Codec Application, which is provided in SDK.

Hi,

Could you share the code to multi task implementation?

The main part in the application, is to provide the buffer index from LDC to encoder using the gst wrapper. Have you replicated this as is?

Are these 4 tasks giving the output of the same LDC node of the same graph?

Yes, I have replicated this but not using GST rather using OMAX wrapper.

No Nikhil, the input LDC node has been received from different graph of different tasks.

And sure, I'm trying to share the code snap with you.
