Hello, We do not provide a webrtc gstreamer plugin. Can you provide more details on what the kvswebrtc plugin is? |

It is taken from amazon-kinesis-video-streams-webrtc-sdk-c gstream sample plugin |

@pmuvvagithub , our gstreamer samples do not have a kvswebrtc. Please point to the code you are using. We would be unable to help without the required details. Also, the issue is potential not related to KVS but the issue is with the source pipeline. Please try your source pipeline out without using kvs, you could try filesink or fakesink to ensure your pipeline is contructed properly before incorporating kvs. |

Does your custom GStreamer plugin advertise support for vp8 in its source pad? For the elements to link the sink pad of vp8enc needs to agree with the src pad of the sink plugin. Once that is resolved, you need to make sure in your implementation if you're running as master you create a local transceiver advertising VP8 support so when an offer is received (remote transceiver) we can respond with the correct answer if VP8 is present in a local transceiver. |

@pmuvvagithub Is this what you're using: https://github.com/aws-samples/amazon-kinesis-video-streams-demos/tree/master/gst/gst-kvs-plugin ? I should clarify here this is in our samples/demos repo and not something that has been actively maintained or thoroughly tested. If this is indeed what you're using then this is where you would specify the support for any additional codecs: https://github.com/aws-samples/amazon-kinesis-video-streams-demos/blob/master/gst/gst-kvs-plugin/src/GstPlugin.c#L104-L105 Finally I would really recommend you spend some time to get familiar with how GStreamer works it will help you a lot in debugging issues such as this question is really a question about the fundamentals of GStreamer and completely unrelated to KVS. Once you're familiar with you source / sink and elements behave and what the pads do and how they need to be set up to "agree" so they can be linked I think you will save yourself a lot of time and headache instead of just trying to hook up components randomly and then not understanding why they cannot link. I hope this helps! |
