Add RTL-SDR mode switcher, DVB-T to Kodi pipeline, FM radio
Mode switcher (rtl_mode_switch.sh) handles exclusive dongle access between DVB-T, FM, SDR scanner, ADS-B, spectrum, and HackRF modes. DVB-T pipeline: RTL-SDR -> GNU Radio demod -> MPEG-TS -> HTTP -> Kodi. Kodi setup script generates M3U playlist for PVR IPTV Simple Client. Includes dvbt_rx.py and sdr_tv.py from dvbt-rx project. WebUI updated with mode switcher, channel selector, and Kodi controls.

# Kodi DVB-T Live TV Setup

# Sets up the pipeline: RTL-SDR -> DVB-T demod -> MPEG-TS -> HTTP -> Kodi
|

#
|
||||
# Kodi PVR connection:
|
||||
# 1. Install "PVR IPTV Simple Client" addon in Kodi
|
||||
# 2. Configure M3U playlist URL: http://127.0.0.1:8554/dvbt.m3u
|
||||
# 3. Or add single channel: http://127.0.0.1:8554
|
||||
#
|
||||
# This script generates the M3U playlist from configured channels
|
||||
# and starts the DVB-T HTTP stream server.
