Extracting motion vectors while using DeepStream

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Hi,

Our original code was using libav to get motion vectors during decode of incoming video stream, similar to:

av_frame_get_side_data(frame, AV_FRAME_DATA_MOTION_VECTORS);

While we are moving our code to deepstream SDK, getting these motion vectors seems to be difficult. Could someone guide us on this? We are conversant with libav as well as NVIDIA’s Video Codec SDK. If there is some hook we can latch on to, kindly help.

Regards,

Hi,

Do you want to extract the motion information from video decoding?
Thanks.

Hi Aasta,

Yes, we want that information from decoding.

Hi,

We are checking with internal team to see any possible solution to get the motion vector.
Will update information with you later.

Thanks.

Hi,

Confirmed with our hardware team that this is not possible with the NVDec in the current generation of products.
Thanks.

Hi,

We also need this feature: to extract the motion information (i.e. motion vector) from video decoding
Does Nvidia support this now?

Thanks.

Hi,
It is confirms to be a limitation and not supported.
