Hi,
Thanks I am really liking ETV so far.
I am finding that I can only get hardware encoding functioning when my channel is configed to use HLS direct, this sometimes means when the channel changes program there is a hand over problem.
I get better playback using MPEG-TS, but would prefer to leverage GPU encoding for a few reasons.
Here are the Nvidia capabilities:
