ENC4SP deinterlacing issue

Hello,

I’m using an encoder ENC5SP with the latest firmware. My cameras output a 1080i50 video. If I switch on the “Encode > Video Config > Full Framerate deinterlace” the SRT stream does not work. If I switch off the “Full Framerate Deinterlace” then the SRT stream works correctly. What is happening?
Ideally, I would like the encoder to deinterlace and convert the 1080i50 into 1080p50. What am I doing wrong?
