Server Version#: 1.32.3.7192
Player Version#: 9.23.0.1746
Since the FireTV has a 100M ethernet port and some 4k streams exceed that bitrate I am experimenting with 4k → 4k transcoding. This should also be useful for remote streams to reduce the bandwidth requirements. The direct play video works just fine.
My server has an A4000 and transcodes just fine. This issue seems to be that it is transcoding 4k 24fps content to 4k 48fps, which exceeds the fireTV cube 3s limit of 4k 30fps for h264 content. Are there any tunable for this or is this a bug in the client/server valid formats logic? I assume its doubling the framerate to keep the UI responsive when refresh rate syncing, but instead of the client doing it the server is transcoding targeting the doubled framerate.
Disabling refresh rate syncing doesn’t work, neither does changing the h264 max level.
