How to get the NvDsFrameMeta structure of the video frame if nvstreammuxer is not used in the pipeline ?

My pipe is shown above.
Is there a method?:Without adding nvstreammux,use gst_pad_add_probe to obtain NvDsFrameMeta structure of video frame from nvvideoconvert_1 plugin.

If you want to get meta info, you should use the nvstreammux. The muxer attaches an NvDsBatchMeta metadata structure to the output batched buffer.

Is there a way to do this without using the nvstreammux plugin?
My application pipeline needs to be stopped and started frequently.
If I used the nvstreammux plugin in front of the osd, the pipeline restart might cause the argus daemon to fail and not capture again,so I wanted to find an alternative to nvstreammux.

No. Nvstreamux attaches the metadata to the buffer. What do you mean by

What is your specific user case?

I wonder if there is another way to add metadata to the buffer.
There is a bug validity probability in streammux plugin that causes argus daemonto hang up, but I don’t have time to follow up on this issue now, I need to find an alternative solution immediately to solve the uncapture problem caused by this bug in users’ hands.

There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.

If you don’t use nvstreammux, you should add it by yourself with Gstreamer API gst_buffer_add_meta. You can define the structure and add the meta to the buffer by yourself.
