Great, thanks.

Works fine now.

It just wasn't possible to find this solution anywhere. Let's hope google will be pointing people to here.

Hi,

Since LE11 does not work well on the RP3 I just upgraded to RPI4.

During this process I finally solved my monitor problem where LE9 always needed to wait for the monitor to boot before switching on. I simply added the line

hdmi_force_hotplug=1 

to config.txt. Issue solved.

Now the RPI4 does not bring any picture after the boot up rainbow. I tried the above hack, but it did not help.

I checked edid info and it looks like the tv is invisible to LE11.

# dump-active-edids
error: no active connectors found
# kmsprint 
Connector 0 (32) HDMI-A-1 (disconnected)
  Encoder 0 (31) TMDS
Connector 1 (42) HDMI-A-2 (disconnected)
  Encoder 1 (41) TMDS

So, is there any way to force Full HD to one the outputs?

thank you very much.

Libreelec 11.0.3, Raspi 3B+, playing from Network.
No heatsink. But it does not get warmer than ~ 40°C

Thanks, I enabled "Adjust Refresh". Had searched for it but hadn't found it yet. You motivated me to try again

but does not help.

4k does not apply to my set-up.

Quote from jbinkley60

Raspberry Pi CPU utilization results:

	30 fps @ 1080P	60 fps @ 720P
7 mbs	70%	65%
12 mbs	88%	75%
15 mbs	100%	85%
20 mbs	100% failed	90% failed
25 mbs	100% failed	92% failed

Am I doing something wrong?

My file is 1.5 mbs and it just lags.

Well, it does not crash and audio is not out of sync.

but it's dropping frames massively. CPU load is rather high. Frame rate goes as low as 8.

It's full HD@25 frames, Main@L4@Main

any idea?

thanks

thanks, posting random links does not help.

I am rather sure it's not about power.

I tried two different self powered hubs.

I use the original raspberry power supply and the USB device uses less than 200 mA / less than 1 Watt when in use. (the rest went to USB hub and power supply, because I measured the brut amount)

problem does not happen on PC.

But it's ok. I give up.

Ok. Tried an external powered hub.

It draws 2 W including power supply and hub. Not that much.

Rasberry draws 3 to 5 Watts w/o DVB.

I got it.

It works when it has been booted before.

I thought it is something about warm or cold state, but no.

If it is the first boot since power-up of the stick, the log shows the following.

when rebooting without power cycling the dvb stick, everything works fine.

I searched through the kernel source but I just cannot find out what this error code stands for. any hints?

It works now. Thank you very much to all of you.

maybe it was because of USB power setting...

Maybe it conflicted with other USB devices, namely the MELE F1 Remote. (I had accidentally two plugged in)

Same on LE12. LibreELEC 6.1.58, nightly build of 23th october.

You have to re-insert the usb device after every boot, else it won't work.

Boot-up log

reinsert log

http://ix.io/4Jo2

any idea?

Yes, everything works fine now on LE11

I can try LE 12 tomorrow if the driver is loaded at boot-up.

It works in LibreElec and on PC/Ubuntu.

But on LibreElec 11 the USB stick does not come up on boot-up. I have to remove and re-insert it.

There should be a simple solution, but I don't know it

I think this is triggered bei udev?

dmesg log of bootup is here:

dmesg log of remove and reinsert USB device is here:

My provider is Synvia. They deliver FTTH (fiber internet). In my flat they mounted a converter from fiber to cable and LAN. No idea what it does.

The symbol rate seems to be 6,900,000 for all muxes.

one of the above was wrong. good one is

c8e089c351e9834060e962356f8697b8 dvb-demod-si2168-b40-01.fw

(fixed it in my post, but couldn't in your quote)

not sure if the vendor id really makes trouble. the stick works fine, even if I do not blacklist the other driver and it is loaded.

thanks.

Yeah, thanks. The device actually works. Problem was I didn't know the exact symbol rates.

There are a ton of sources for firmware, not all identical, some broken.

I made it work with these

$ md5sum *
d8da7ff67cd56cd8aa4e101aea45e052  dvb-demod-si2168-02.fw

This is a completely different device.

but that was the plan already in the first place.

Trying different platforms to make it work.

My backup laptop broke down yesterday while tring to build 6.5 kernel.

Got another spare PC now for experimenting.

ps: seems like one of the firmware files was bad. replaced it and now I get the "buggy device" messages again. So same state as on the PC.

see http://ix.io/4JKR

next try is compiling 6.5 kernel

but maybe I should give up trying on libreelec for now. Will mark the thread as "given up".

thanks to all people who tried to help.

Wow, thank you very much.

haven't found these myself.

Quote from petediscrete

It can. Do you have one single known active mux from your cable supplier.

ah. cool.

I now got a list, but it's missing the symbol rate

any idea what to try for eg. 266 Mhz 256-QAM?

thanks, this is the guide i followed.

on the PC it does not need sub directories.

and in the log it does not use sub directories as well.

so if I should place it into a sub dir, what dir do you suggest?

or is there anything else I was wrong about?

Still does not work.

Where do I put the firmware? Looks like it did not find the firmware in

/storage/.config/firmware/

dmesg says

I understood TVHeadend cannot scan for muxes?

Is there a way to force scan for muxes?

I use the Terratec CINERGY TC2 USB Stick, but wasn't yet able to see any input. So not sure if it actually is working.

Hi,

I've got a niche DVB-C provider so I had to scan for muxes myself.

The official way is to use DVBSCAN which does not work as 1) it's not installed on LibreElec, 2) it always needs a muxes definition as input.

but: you can use W_SCAN to search for muxes.

• Just fetch the binary for your platform from debian repo
  https://packages.debian.org/bookworm/w-scan
  https://packages.debian.org/bookworm/dvb-apps --not sure if w_scan depends on this
• shut down tvheadend, as it blocks the DVB devices.
• extract the deb (I used Ark), but should be tar.xz file... so just tar xf ...deb
• tar xf data.tar.xz
• export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:(absolute path to usr/lib) --not sure if w_scan depends on this, but dvbscan does
• cd usr/bin
• ./w_scan -f c --c for cable, t for DVB-T and s for DVB-S

does not find any muxes for me. why?
