hello, I have problems with mumudvb, am I right here?
in case I am: I can watch a stream using vlc dvb-t2://frequency=570000000:bandwidth=8:ts-id=515
but http://paste.debian.net/1030182/
strace at http://paste.debian.net/1030183/
(https://github.com/braice/MuMuDVB/issues/210)
If DTV_STAT_ERROR_BLOCK_COUNT is not increasing should I be seeing a perfect capture?

lol
Any word on the em28xx stuff?
i think i found it, if you want to try, but the fix is a 'fix of a fix of a bork' lol
I LOVE THOSE
;P
turns out the bork might have been correct lol
Bandaids are the best
/s
But they can do in a pinch
try revert em28xx-cards: fix em28xx_duplicate_dev 3f127ce1135 from Mar 08
i think now it's duplicating too much and pulling the rug out from under itself
at least i revert that and i don't get the unplug oops on 4.15, i'll test mainline in qemu after coffee
b-rad, I made this just for you https://i.imgur.com/aZnfGaT.png
lol
Hello. I have IconBIT TV-Hunter Studio device (lsusb: 1b80:e608 Afatech, see lsusb-vvv, dmesg, : pastebin.com/T7BmJwBk), I guess it has eMPIA EM2980 inside. It's detected as a soundcard ("USB 28286 Device at usb-0000:00:1a.7-2, high speed")... and that's it. No video device file. Am I missing something? Is my kernel too old (4.9)? Or is the device not supported at all?
(And if it's not working at all... Can I help to make it working somehow?)
oops, wrong pastebin, this is the correct one: https://pastebin.com/w2keF1qL -- dmesg, cat /proc/asound/cards, lsusb -vvv
debianuser, is it a tuner or just capture card? Giving me a lot of russian results
It's a capture card, it looks like this: https://www.ixbt.com/divideo/iconbit-tv-hunter-studio/01big.jpg  https://www.ixbt.com/divideo/iconbit-tv-hunter-studio/02big.jpg  https://www.ixbt.com/divideo/iconbit-tv-hunter-studio/03big.jpg
Ok so plain capture. There wouldnt be a dvb device at that point. You would most likely get a /dev/video* V4L device but it seems like even that isnt picking up
Both of the afatec drivers Im seeing in the kernel are for DVB-T devices (af9033 and af9013)
Seems to just be not suported at all. The Afatect devices I'm seeing are all DVB based
*supported

no more disconnect oops on 4.17, but both tuners no longer work at same time in qemu :/
b-rad, Is that with the revert you mentioned?
(Im compiling that now)
yup
Assuming this is what you were referring to https://www.mail-archive.com/linux-media@vger.kernel.org/msg127390.html
yes
hmmm...ubuntu qemu vm with 4.4 + media tree can't handle the dualhd either
guess i just thought it worked
b-rad, You saying it can't handle the D? :)
b-rad, Weird part is I remmeber testing your patches early on before merges and they worked fine
the revert was post merge
rightfully noticed something fubar
4 months ago https://i.imgur.com/ezeqBC6.png I didnt take not of the kernel version :/
*note
is that in vm though?
everything is fine on my ryzen tester
Naah thats on laptop on Arch
far as i know non-vm usage should be fine, sans your disconnect oops
Oh so viewing two should be fine?
"but both tuners no longer work at same time in qemu" I thought that was translating to real hardware also
i sometimes run low on real hardware to test on lol
so most happens in kvm qemu
Ok so with that revert I should have everything functioning
Still compiling
well real pc's, got a freakin bazillion random embedded boards
i am not seeing your disconnect oops in 4.15 or 4.17, and 2x w_scan worked fine in 4.15
so should be good
b-rad, lol managed to catch it in the copile output https://i.imgur.com/OWsqdAn.png
*compile
ParkerR: Thanks for checking! Yes, no /dev/video* files are created when I plug the device in... I've tried to google around for "eMPIA EM2980" and "eMPIA 28286" (as dmesg says "Product: USB 28286 Device") but haven't found much... Maybe I can help to make it working? Test something or provide any other information?
b-rad, :( So that fixed the oops but the devices still shits itself on dual access

Thats the second stream trying to load
And then the first died shortly after
do you see anything in dmesg?
Nope. Just that the secon tuner was initialized
AV: 00:00:42 / 00:00:48 (87%) A-V:  0.000 Dropped: 2 Cache:  6s+7MB
[dvbin] dvb_streaming_read, failed with errno 11 when reading 8192 bytes
[dvbin] dvb_streaming_read, return 0 bytes                 
Thats the furst stream dying
hrm
b-rad, https://gist.github.com/parkerlreed/81eaf3289c500a7e29602565b6728f50
There's the end of dmesg
always nice when crickets chirp during error conditions
i'll actually try and watch two streams on a pc instead of 2x w_scan
will just need do some musical cables
Hehe
well decoding looks horrible on my ryzen system, but vlc is streaming both tuners on different frequencies together
Odd
that is 4.13 ubuntu bionic with my media tree integration
newer kernels don't like booting on that machine
Yeah still 4.18-rc1 on my end
Ill try VLC in case its different
ryzen + forced nvidia gpu don't like mainline in ubuntu
b-rad, Obviously you just need to Arch/Gentoo ;)
i tried latest nouveau etc, nothing would boot last a month or two ago
Yeah thats why I avoid Nvidia. Completely dont help the OSS side at all
it stupidly took me a couple days just to figure out my r3 had no onboard graphics and needed the gpu to even post
since the mobo had hdmi/dp lol
Wow
people said 'first ryzen boot takes ages' so i let it sit for like 12hr lol
Ogod
b-rad, Odd mines not even stable accessing one tuner. w_scan worked. Went to play in VLC didnt load, tried mpv got that same 8192 byte error, replugged, worked in mpv, subsequent failed to load
Yep anything accessing it, works once per replug
https://gist.github.com/parkerlreed/fbaae3844d8a34dbe3e40849a8d522f1
Upon exiting a program it never seems to close the tuner
Which would explin the subseqent runs fialing
*explain
*failing
i disabled hw dec and now both tuners are fine for me
including subsequent usages
I wonder how hw dec is playing into that 
i mean the decoding
Hmm?
they were delivering data fine before, it was just rendering horrible
now i can tell both are in reality fine video/audio
em28xx doesn't have much debug, but you might try looking at its option and turning on everything
parm:           core_debug:enable debug messages [core and isoc] (int)
parm:           reg_debug:enable debug messages [URB reg] (int)
?
i might give 4.15 and 4.17 a shot and see if they'll boot now
probably just core_debug
hmmm...what you said just reminded me of something
i was having problems with dualhd on some platforms i'm backporting to, and they as well worked once and never again per plug
i fixed it by applying a couple patches from my analog set
to enable tuner status flags and some validation/retries
and then voila, worked like usual
b-rad, You're going to think Im crazy
Subsequent runs work with debug enabled
nice and racey then eh
welcome to my world of ryzen
shtf nothing works, enable tiny amount of instrumentation, works but other stuff broke
apply patches 1-4 from my si2157 analog tuning series, then see if it works again without debug
Aha even without debug I found the issue. Timing. If I try retsarting it too fast I hit the rror condition
If I let it sit for a second it comes up fine (98% of the time) Still an occasional error condition even waiting
Also I just noticed vlc actuall timestampts the progress bar based on EPG now
Neat
Has EPG title and current show progress https://i.imgur.com/6RpO8Xp.png
I dont remember that being there lol
Also VLC sometimes hangs on exit never closing the tuner
Odd
i noticed that recently in ubuntu bionic, but didn't thinkg about it
b-rad, It's kinda pissy. Only place I get signal is at work... where I need to be working lol. Only place I can test
yeh i live about 38mi from the transmitter so my signal is just plain shyte
I live 6 miles from a tower
But its at the top of a motunain and Im at the base
Flies right the fuck over
on a good day i pick up 12 frequencies, today i get 2 barely
https://i.imgur.com/h4I7yC8.png
Damn trees
ok, so i do have patch 7 from that series applied too unsure if it was required or if i was just doing some timing
b-rad, It's odd. I have a fascination with ATSC/DVB tuners but where I live is just shite reception for everything lol
Even FM reception is meh
Remember back when USB was only for control? :) https://i.imgur.com/9MT2IE2.jpg Good ole WinTV-USB
before my day :)
i lived in canada for 8yr and my options there were non-existent
well those patches don't help qemu do both tuners at once, but one worked fine
b-rad, So the tuner was just idling plugged in and my enitre USB bus crashed
Huh just recovered midway
Odd
https://gist.github.com/parkerlreed/86858082dfa3f9ee38cb8b73d96be8b7
trying to get 4.17 working on my ryzen pc now, i was on 4.15 and that was fine
see if maybe 4.17 fails for me
Had to reboot. Devices kept cycling. How weird
the patches to em28xx are minimal since "things worked"
