Exception: Failed to make element sink of type kvssink

[leagerl1]

Hello,

Installing and attempting to use aws-streamer we encounter the error Exception: Failed to make element sink of type kvssink. I think this has to do with the fact that either kvssink or the bindings aren't installed due leaving off the cmake arguments to enable it but i noticed when installing with

RUN pip3 install -v git+https://github.com/awslabs/aws-streamer.git --install-option "build_ext" --install-option "--cmake-args=-DBUILD_KVS=ON"

as per the instructions we get the error

 error: option --cmake-args not recognized

Any suggestions as to what might be wrong here?

Hi,

I see that some of the behaviour of pip has changed (become obsolete). I've checked the following combination works well:

git clone https://github.com/awslabs/aws-streamer.git
cd aws-streamer
python3 setup.py install
python3 setup.py build_ext --cmake-args=-DBUILD_KVS=ON

It's the build issue, not run-time. kvssink failed to compile on your system. Please look for error messages in the build log and make sure you have all the prerequisites installed.

You can also attempt to build the kvssink plug-in manually following these steps: https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp
