Tvheadend

I got the new mpeg-ts spawn profile working. Tvheadend now transcodes using my custom scripts;
i have a script in /home/hts/scripts/stream2.sh that looks like this
#!/bin/bash
ffmpeg -analyzeduration 1M -probesize 1M -i pipe:0 -bitrate 3000k -bufsize 3000k -c:v libx264 -preset superfast -c:a aac -c:s copy -f mpegts pipe:1

, and it works well with VLC or my Android client TVHClient which does not rely on HTSP.
Kodi on the other hand does not see the MPEG-TS Spawn/built-in profile. When playback start is falls back to using the pass profile.
Kodi can use the transcode/av-lib profile, but that does not fulfill my transcoding needs
