Hi,
I am trying to measure the latencies of nvv4l2h265enc & nvv4l2decoder elements on Jetson Nano board, and i have observed that latency of nvv4l2h265enc is ~4 msec and latency of nvv4l2decoder is ~3 msec.
I am using below pipeline.
GST_DEBUG=“GST_TRACER:7” GST_TRACERS=“interlatency” GST_DEBUG_FILE=camerasrc_nvv4l2h265enc_nvv4l2decoder_fakesink.log
gst-launch-1.0 nvarguscamerasrc num-buffers=900
! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, format=(string)NV12, framerate=(fraction)30/1’
! nvv4l2h265enc preset-level=1 MeasureEncoderLatency=1 maxperf-enable=1
! nvv4l2decoder enable-max-performance=1 disable-dpb=true
! fakesink
I have attached the log files of encoder and decoder latencies.
Could you please confirm whether the latencies are proper ?
Are these the expected results ?
If no, let me know the expected results of latencies for both nvv4l2h265enc and nvv4l2decoder.
NOTE: i am using Rasberri Pi NoIR camera for capture element.
Thanks,
