Hi, how can we prioritize using H264 codec over VP8 in OpenVidu PRO configuration? I believe previously you could re-arrange two key values in SdpEndpoint.conf on the server? ---

There is not configuration parameter to prioritize one code over the another. If changing values in SdpEndpoint.conf works for you, you can create a custom KMS docker image and configure it in `.env` file. ---

I just post here to update to people who find this post after 2020. Force codec is supported from version 2.17.0 using this parameters in /opt/openvidu: - `OPENVIDU_STREAMS_FORCED_VIDEO_CODEC` - `OPENVIDU_STREAMS_ALLOW_TRANSCODING` By default it is `OPENVIDU_STREAMS_FORCED_VIDEO_CODEC=VP8` and `OPENVIDU_STREAMS_ALLOW_TRANSCODING=false`
