the command-line is not correct. please refer to the readme of test4. you can try the following two cmd.

$ ./deepstream-test4-app -i <H264 filename> -p <Proto adaptor library> --conn-str=<Connection string> --topic=<topicname> -s <0/1>
$ ./deepstream-test4-app dstest4_config.yml

i tried both

./deepstream-test4-app dstest4_config.yml

msg2p_meta = 0
Using file: dstest4_config.yml

  1. could you share the dstest4_config.yml? you need to set the custom configuration for msgbroker.
  2. from the “unable to connect to broker library”, seems the client can’t connect to the server. you can use the tool in /opt/nvidia/deepstream/deepstream/sources/libs/redis_protocol_adaptor/ to test the client library. please refer to the readme under the directory.
