I am following the step in this video, using ```
nvcr.io/nvidia/deepstream:6.2-devel


From 23:00, the makefile shows mistake on finding google/protobuf in -I./deepstream_schema,
so I manually add  -I../../includes after CFLAGS+=.
After it compling successfully,I ran make install. The libnvds_msgconv.so file is in /opt/nvidia/deepstream/deepstream-6.2/lib and /opt/nvidia/deepstream/deepstream/lib

then go to the folder ran the cmd as the video shows.

the DEGUG=2  error log shows

**•	Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)**

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. Thanks

Can you elaborate how you installed DeepStream6.2 on your host? Can you run any sample in directory sources/apps/sample_apps or any other deepstream_app samples?
nvmsgconv is a plugin from DeepStream, not able to find this plugin indicates it may be related the installation of DeepStream on your host.
