Hi,

The source code are in
https://developer.nvidia.com/embedded/dlc/r32-3-1_Release_v1.0/Sources/T186/public_sources.tbz2
Both gst-omx and gst-v4l2 packages are open source.We are deprecating omx plugins so please check gst-v4l2.

You can set up QP range:

  qp-range            : Qunatization range for P, I and B frame,
                         Use string with values of Qunatization Range
                         in MinQpP-MaxQpP:MinQpI-MaxQpI:MinQpB-MaxQpB order, to set the property.

Or set up fixed QP value:

  quant-i-frames      : Quantization parameter for I-frames (0xffffffff=component default),
                         use with ratecontrol-enable = 0
                         and preset-level = 0
                        flags: readable, writable, changeable only in NULL or READY state
                        Unsigned Integer. Range: 0 - 4294967295 Default: 4294967295
  quant-p-frames      : Quantization parameter for P-frames (0xffffffff=component default),
                         use with ratecontrol-enable = 0
                         and preset-level = 0
                        flags: readable, writable, changeable only in NULL or READY state
                        Unsigned Integer. Range: 0 - 4294967295 Default: 4294967295

But we don’t support configuring QP value of each frame.

We have th eproperty in nvv4l2h265enc:

  EnableMVBufferMeta  : Enable Motion Vector Meta data for encoding
                        flags: readable, writable, changeable only in NULL or READY state
                        Boolean. Default: false

Not sure it it is the data you need. Please enable it and check.

Now we support fixed framerate. Supporting VFR is under evaluation. Please check
