Error while saving Encoding Profile!: field 'videoStreamConfigs.codec' is invalid! valid values: (h264,hevc) Source is vp8 webm @ 4000x2000. I chose the 1080p adaptive profile and tried to add 4kx2k @ 20mbps and 2kx1k @ 15mbps. Both of the added show encoded of vp8 but don't allow me to change it to h264. Codec: vp8 FPS: 25.00 Bitrate: 15.00 Mbps Resolution: 2000x1000 I previously encoded the same video just using the 1080p adaptive profile and am unable to convince the player to treat it as 360 video.
