I give up for python, in c++ I can get read/write USER_META without batch_meta.

You can refer to our C/C++ demo sources\apps\sample_apps\deepstream-gst-metadata-test to implement that in Python.

Hi yuweiw, Do you have some example how do I replace below lines with Python code? /* Attach decoder metadata to gst buffer using gst_buffer_add_nvds_meta() */ meta = gst_buffer_add_nvds_meta (buf, h264parse_meta, NULL, h264parse_meta_copy_func, h264parse_meta_release_func); /* Set me…

From the Python API I can invoke gst_buffer_add_nvds_meta like below, but I don’t know how do I provide that copu_fun and release_func? pyds.gst_buffer_add_nvds_meta(hash(buf), timestamp,v2x_meta_data_copy_func,v2x_meta_data_release_func) [image]

@yuweiw Actually I am reading this customized NvDsUserMetaData. But my problem is I don’t how to read/write this kind of NvDsUserMetaData in my probe. As you can find I want to write below SEI timstamp into metadata. But inside this probe, there is no batch_meta to be accessed. And all of sample co…

If you have alternative ways to pass parameters between probe for same frame. It also can help me.

You can refer to our demo deepstream_custom_binding_test.py to pass the NVDS_USER_META between probe.

I learned this sample code. But it still only pass USER_META between 2 probes which can access batch_meta = pyds.gst_buffer_get_nvds_batch_meta(hash(gst_buffer)). And from my case, one of probe, I can’t access batch_meta. That’s why I want to know how to read/wirte USER_META in that kind of probe. …

[image] wei.zhang12: And from my case, one of probe, I can’t access batch_meta. That’s why I want to know how to read/wirte USER_META in that kind of probe. This is weird. Maybe the metadata was lost during the transformation from nvvideoconvert or other plugins. Could you add the probe fun…
