After my last topic,Nvv4l2h265enc crash problem
On 32.5.0/tx2,
Set up this env:export GST_DEBUG=2
There are a lot of warning. Failed to determine interlace mode; Failed to probe pixel aspect ratio with VIDIOC_CROPCAP: Unknown error -1 Opening in BLOCKING MODE Opening in BLOCKING MODE log print twice ?
How to resolve these warnings?

if i change nvv4l2h265enc to omxh265enc plugin ,it also have a lot of warning. plugin_init failed,no config file;setting temporal_tradeoff failed;

Hi,
These look harmless and you should get valid h265 stream if you save to a file. We get the code of gst-v4l2 from 3rdparty and enable hardware acceleration. And certain warning messages are not taken care, but these are harmless and can be ignored.
If you do not get valid h265 stream, please share the steps so that we can replicate the issue and work with teams for further investigation.
yes,these look harmless,and pipeline run fine;
But the last topic memory leak problem remains, Nvv4l2h265enc crash problem 0:03:33.169063483 30128 0x55a1686040 TRACE GST_TRACER :0:: object-alive, type-name=(string)GstCaps, address=(gpointer)0x7f9808a320, description=(string)video/x-h265, stream-format=(string)byte-stream, alignment=(string)au, ref-count=(uint)1, trace=(string);
