WhoWhatWhen
eelstrebori did a minimal config for mumudvb.conf but i get https://pastebin.com/6hLGgxJ7
i'm assuming that the error is something to do with mumudvb.conf but i don't see a problem
[16:32]
ok, i figured it out
eelstrebor wishes he could find a blind scan utility for linux
[16:47]
........ (idle for 39mn)
ukleinekhello, I bought a dvb-t2/c stick and there is no driver automatically loaded. usb id = 1d19:0100 Dexatek Technology Ltd. does it make sense to try to make it run, or should I better return it as long as I can? [17:27]
...... (idle for 29mn)
cristian_cukleinek: what about does dmesg say? [17:56]
ukleinekcristian_c: http://paste.debian.net/1029762/
this is a 4.16 debian kernel
ukleinek suspects I need to load firmware somehow
[18:04]
there is only a single match for the vendor id in the kernel tree [18:19]
b-radite makes af90xx chips
i think
af9033 and af9035 have drivers of some sort
[18:22]
ukleinekI see af9005.c
drivers/media/usb/dvb-usb-v2/rtl28xxu.c has some dexatek devices
[18:24]
b-radaf9015 and af9035 are both in that dir as well
you're shooting blind if you don't know what any of the chips inside are however
[18:27]
ukleinekah, i see
ukleinek goes and finds a machine with a cdrom drive to check what driver is included on the cd
[18:28]
b-radso maybe mauro will show up and magically just know whats inside [18:28]
cristian_chttps://patchwork.kernel.org/patch/9613771/
ukleinek: so, you should at least trying to look for the firmware
[18:42]
ukleinekcristian_c: on the cd you mean? There is nothing helpful [18:55]
ukleinek recompiles with the patch
there is something newer: https://www.spinics.net/lists/linux-media/msg112928.html
[19:06]
the patches don't fit though :-| [19:16]
cristian_chttp://www.ubuntu-forum.de/artikel/67406/suche-firmware-f%C3%BCr-dvb-t2-usb-stick-dvz-300-t2c-von-auvisio.html
another user said it's not supported
ukleinek: https://trac.videolan.org/vlc/attachment/ticket/20534/gonzo_dvb.patch
(from https://trac.videolan.org/vlc/ticket/20534 )
' This is the patch to make my stick work. '
' Ok, it seems to work now, I had to click in the thumbnail on the bottom left. How do I close a ticket? '
[19:19]
ukleinekseems to be related to https://www.spinics.net/lists/linux-media/msg112928.html [19:25]
cristian_cukleinek: btw, your cpu must have HEVC support for this dvb-t2 usb stick
*graphics
[19:25]
ukleinekcristian_c: how do I find out if it does? [19:26]
cristian_ca not so old cpu
with onboard graphics
[19:26]
ukleinekukleinek has a i5-6440HQ [19:27]
cristian_cso, it'senough
to decode video stream
ukleinek: btw, look at the patch I've linked
that vlc thread shows a user has tried it and he confirms it's working
gonzo_dvb.patch
[19:27]
ukleinekneeding HEVC is not specific to this stick, but to dvb-t2 in Germany, right? [19:30]
cristian_cO.o
hevc is about video decoding / compression
*encoding
h.265
[19:30]
ukleinekbut the stick probably only provides what the ether gives it and doesn't transcode, does it? [19:31]
cristian_cdvb stick streams signal and graphics plays the stream
I thinf it it wasn't, cpu usage would raise to 100%
from hardware ecode to software decode
[19:33]
ukleinekcristian_c: so the dvb-t signal isn't encoded in HEVC? [19:41]
cristian_cI think so
it should be decoded
so, ifmyou've that cpu, I think you've a nvidia + intel card
[19:42]
ukleinekit's a thinkpad laptop with intel graphics [19:43]
cristian_cyou've not issues with hevc, I think
so, you could look at the patch
if you had an old celeron, then maybe no hevc hw support
[19:43]
ukleinekmaybe I need to use this on an slightly older thinkpad because it has an vga output for the beamer.
anyhow, I resolved the conflict in the patch by Andreas Kemnade
