You can use an IPTV network with a
pipe://
URI using ffmpeg' h264_vaapi codec. However, that is presently the only way I know of to use vaapi with Tvheadend.
Your other option is to modify the source to implement vaapi transcoding.
Using a dynamically linked ffmpeg with Tvheadend to get vaapi encoding is broken in Tvheadend, as it passes additional options that are hardcoded to avlib that cause errors upon trying to create the stream. This is mostly due to passing profile and preset options which work for libx264, but not h264_vaapi, as far as I can tell.
