Hi all,
Is it possible to obtain pitch memory layout buffers from nvarguscamerasrc or libargus?
I know that nvarguscamerasrc GStreamer plugin provides NV12 NVMM buffers. After a deeper inspection, I figured out that does buffers are in blocklinear memory layout.
I have found that nvvidconv GStreamer element has a particular property to force the NV12 NVMM output buffers to be in pitch or blocklinear memory layout. Below is the extracted property information from gst-inspect-1.0 nvvidconv
command:
bl-output : Blocklinear output, applicable only for memory:NVMM NV12 format output buffer
flags: readable, writable
Boolean. Default: true
This property by default is true, so it forces the blocklinear memory layout on NVMM NV12 output buffers case.
I want to take out pitch memory layout NVMM NV12 buffers directly from nvarguscamerasrc GStreamer plugin or libargus API. Is there a way to achieve that in a similar way as nvvidconv element does?
I am working on a custom GStremaer element that is capable to consume NV12 NVMM buffers, but currently it only works if the incoming buffers came from the nvvidconv with the bl-output set to false (forced pitch memory layout). I want to get rid off the nvvidconv element from the middle to increase my performance specs.
I am using theJetson Xavier platform with JP4.4.1 L4T 32.4.4.
Any help will be appreciated.
Best regards,
-Daniel
