How to instruct A8 VLPB OMX component to allocate buffers on shared region 2

Hi Gabi,

decode_mosaicdisplay example has usage of allocating buffer on A8 from SR2 and using it. You can try using that.

Hi Vimal,

Thank you very much for your answer, but i didn't see any usage of A8 VLPB in the decode_mosaicdisplay example.
The example of C6xtest can be change to use A8 VLPB, but the buffers are not allocated in shared region 2. 
Can you please answer how to use A8 VLPB and allocate its buffers in shared region 2?
Can you please also help with allocating of VLPB on DSP buffers in shared region 2 in EZSDK ver 5.04?
Please see http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/210846.aspx 

Thanks,

Hi Gabi,

You want to use SR2 buffers in DSP ? It would require setEntries for SR2 in dsp firmware. Also SR2 owner in firmware_loader would need change. we are looking into this.

Hi Vimal,

I want to use SR2 buffers for both DSP and A8 OMX components, i am awaiting for your solution.
This will help creating OMX chain that can use the DSP and the Neon on A8 for processing video frames.

Hopefully it will be a permanent solution for all new EZSDK versions from now.

Thanks,
Gabi 

Just wanted to chip in to say I'm after exactly the same thing as Gabi;

-I need to be able to get the DSP to work with Shared Memory 2 buffers as I must use the DSP to convert from RGB 24 bit data captured using the V4L2 driver into YUV420 data so that it can be encoded to H264 by the HDVICPs. In case you wondered, I need RGB 24 bit data for my algorithm that runs on the ARM.

Hi Ralph,

I am also working on exactly same usecase you described.

Did you get any success?

Hi Vimal,

I also use vlpb OMX component on DSP and I also want to use ezdk  5.04.

When do you think the solution would be released?

Thanks.
