mplayer doesn't show video when accessing to a DVB-T tuner device

[mister.freeman@…]

Summary of the bug:
mplayer doesn't manage to show video when I want to watch TV with my DVB-T tuner, there is no error message in the console, all seems Ok, but there is no video window (and no sound),

I use archlinux 64 bits, kernel linux 4.17.8, graphic card: amd radeon HD4650 pcie with radeon driver, DVB-T tuner : winfast leadtek DTV1000-T pci,

mplayer version : MPlayer SVN-r38101 (C) 2000-2018 MPlayer Team
225 audio & 464 video codecs

I tried with vdpau driver, x11 driver --> no improvement,
mplayer worked great few months ago, I don't why it fails now

How to reproduce:
watch TV with mplayer by typing this in a console :

mplayer dvb://France2HD

output of the console :

MPlayer SVN-r38101 (C) 2000-2018 MPlayer Team
225 audio & 464 video codecs
do_connect: could not connect to socket
connect: No such file or directory
Failed to open LIRC support. You will not be able to use your remote control.
Loading extension-related profile 'vo.vdpau'

Playing dvb://France2HD.
dvb_tune Freq: 530000000
TS file format detected.
VIDEO MPEG2(pid=120) AUDIO A52(pid=130) NO SUBS (yet)! PROGRAM N. 0

then that's all, no error message, and no video windows, and no sound,

If I use another player (vlc, kaffeine) then I can watch TV from my DVB-T device,

If I try to watch a video file with mplayer (h264, ts file, mpeg2 file, m2t file) then all is ok, no problems,

the problem occurs when I want to watch TV with my DVB-T tuner, mplayer seems to find my DVB-T device, no errors, but mplayer doesn't display a video window and there is no sound

however If I dump the DVB-T stream with mplayer then the file can be readable with mpv player :

mplayer -dumpstream dvb://"France2HD" -dumpfile stream.ts
