Video is not smooth and jittery while executing “gst-launch-1.0 nvv4l2camerasrc ! ‘video/x-raw(memory:NVMM),width=3840,height=2160’ ! nvvidconv ! nvv4l2vp9enc bitrate=25000000 ! nvv4l2decoder ! nv3dsink”.
CPU overhead is low and no error/warn messages are displayed
If I change bitrate from 25M bps to 5M bps, some warning messages are displayed:
WARNING: from element /GstPipeline:pipeline0/GstNv3dSink:nv3dsink0: A lot of buffers are being dropped.
Additional debug info:
gstbasesink.c(2902): gst_base_sink_is_too_late (): /GstPipeline:pipeline0/GstNv3dSink:nv3dsink0:
There may be a timestamping problem, or this computer is too slow.
Then I tried nvv4l2h265enc, video is also not smooth and jittery. And it seems bitrate parameter is not working for h265 encoder? (because video qualities with different bitrate valuse is the same)
If just capture/render, the video is very smooth at 4Kp30,
