Probably does much more: + add support DVB-T2 * DVB params set to AUTO by default * MAX_CARDS: 4 -> 16 * DMX_SET_BUFFER_SIZE: 64kb -> 256kb + add DTV_CLEAR call before tune + add logic from https://github.com/olifre/mpv/commits/dvb-mixed-api-scan * rename type to delsys * single playlist per adapter * card -> adapter * fix channels order in playlist * update internal api * auto fallback to old DVB API on tune * fix DELSYS_SUPP_MASK value * remove tone - unused * add channel mem zeroize in config parser + add code from libdvbv5 for detect delivery systems * SYS_DVBC_ANNEX_AC replaced to SYS_DVBC_ANNEX_A + SYS_DVBC_ANNEX_C Signed-off-by: wm4 <wm4@nowhere>
