| hverkuil | svarbanov: the daily build reports a number of sparse/smatch warnings for the venus driver, see https://hverkuil.home.xs4all.nl/logs/Wednesday.log
There are also a bunch of kerneldoc warnings for the venus driver, it would be nice if that's also fixed. | [07:31] |
| GBenji | hverkuil: thanks for your review of hevc patches, I hope that the next version will be better :-) | [07:36] |
| phk | hi
I am not able to make MAX SX8 working in linux! Im getting this error in kernel logs https://pastebin.com/cAFPqXka Linux rf-linux 5.4.0-70-generic #78-Ubuntu SMP Fri Mar 19 13:29:52 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 20.04.1 LTS anyone have any ideas, how can i fix this? dvb_core: disagrees about version of symbol media_devnode_remove dvb_core: Unknown symbol media_devnode_remove (err -22) im getting this kind of msg in dmesg | [07:39] |
| hverkuil | phk: check if you perhaps have two mc.ko modules in /lib/modules/`uname -r`
You get messages like that if the versioning of the module that is loaded does not match what the driver expects. | [07:41] |
| phk | ./kernel/drivers/media/mc/mc.ko
i get only one file in "find . -name 'mc.ko'" hverkuil: may be, not sure, using this device for first time and having driver issue ;( | [07:43] |
| svarbanov | hverkuil, thanks for the heads-up. I will take care for them. | [07:48] |
| phk | "/lib/modules/5.4.0-70-generic/extra/ddbridge/ddbridge.ko"
is this the correct path of ddbrindge? wondering why its in "extra" directory | [07:48] |
| hverkuil | phk: also check for media.ko | [07:56] |
| phk | hverkuil: not found
there is no media.ko | [07:57] |
| hverkuil | OK. Than I would say that there is something weird with ddbridge.ko. 'extra' is weird. It's in kernel/drivers/media/pci/ddbridge/ on my distro. | [07:59] |
| phk | i have there too!
ddbridge-dummy-fe.ko ddbridge.ko files init but if i try lsmodinfo ddbridge i get path with "extra" init | [08:00] |
| hverkuil | I'd remove that driver in extra, run 'depmod -a' and try again.
seems that there is some old version of ddbridge in extra for some reason. I have no 'extra' directory at all on my ubuntu 5.4.0-66. | [08:01] |
| phk | can i do rm -rf extra? | [08:02] |
| hverkuil | Well, I'd just move it to somewhere else. I'm not sure what else is in 'extra' or where it came from. | [08:03] |
| phk | in extra there are 3 directories: ddbridge dvb-core frontends
and im 99% sure, there are created after installation of driver from digital devices | [08:05] |
| i moved extra directory and run depmod -a, nothing happened!
nothing in dmesg | [08:10] | |
| hverkuil | phk: you need to reboot. | [08:11] |
| phk | sudo modprobe ddbridge output: https://pastebin.com/TvTqcJyz
rebooting now | [08:12] |
| after reboot, nothing in dmesg, dvb_core or ddbridge not loaded too
and if i try to insmod manually i get this error insmod: ERROR: could not insert module kernel/drivers/media/pci/ddbridge/ddbridge.ko: Unknown symbol in module | [08:22] | |
| hverkuil | works fine here. | [08:26] |
| phk | weird, lets me mail their support
it doesnt make sense to me | [08:28] |
| hverkuil | You installed something from 'digital devices'? | [08:28] |
| phk | http://support.digital-devices.eu/index.php?article=152
i have installed like they have said yes yes, hverkuil i have installed DD Max SX8 device "ddbridge: module verification failed: signature and/or required key missing - tainting kernel" what does this mean? | [08:29] |
| hverkuil | Urgh, they make their own dvb-core. What a mess.
it means that the module was apparently built against an unsigned kernel, which it is since it is an out-of-tree driver. Sorry, we don't support out-of-tree drivers. You'll have to talk to them. | [08:33] |
| phk | no problem, thank you very much :pray"
no problem, thank you very much :pray: and already mailed them | [08:35] |
| hverkuil | Are you sure you need their out-of-tree driver? The in-kernel driver doesn't support your hardware? | [08:36] |
| phk | no, default kernel driver doesnt support | [08:36] |
| hverkuil | I see references to Digital Devices MAX S8 4/8 in the kernel code. | [08:36] |
| phk | yes, i show that too
but its not working at all as you know i have removed "extra" directory and rebooted machine so it should be working if default driver/module support that device | [08:36] |
| hverkuil | Daniel Scheller <d.scheller@gmx.net> did some work upstreaming code from the dddvb-0.9.33 release. You might want to check with him, he clearly knows about this stuff.
They really should work upstream to ensure proper support of their hardware. | [08:38] |
| phk | well, in modinfo i see author: Ralph and Marcus Metzler, Metzler Brothers Systementwicklung GbR
may be they have changed their drivers | [08:43] |
| hverkuil | they haven't worked on it for ages. In any case, start with Digital Devices themselves. | [08:44] |
| svarbanov | hverkuil, what make rule to use in order to reproduce venus kerneldoc: WARNINGS ? | [08:48] |
| hverkuil | svarbanov: no make rule, otherwise we'd seen this before :-(
You manually run this: scripts/kernel-doc -none <headerfile> public headers are checked when building with W=1, but not kernel-internal headers. I've added support for that to the daily build so that it is now verified. | [08:49] |
| svarbanov | hverkuil, ahh, now I understand why did not see kernel doc warns | [08:50] |

| ctr49 | hello everyone!
does anyone have a syntax hint for me for piping raw video data into a v4l device using v4l-ctl? I want to build a pipe like v4l-ctl -d0 --stream-to=- | do-stuff | v4l-ctl --stream-from=- | [10:23] |
| but I'm unsure if this is supposed to work with v4l-ctl at all and how to specify the target device. I tried with "-e" but get a "VIDIOC_G_SELECTION returned -1 (Inappropriate ioctl for device)" as result while having ffmpeg pipe into the v4l device works perfectly fine | [10:32] | |

| Inky1003 | Hello. I'm with a EzGrabber2 which haves the cx23103 chip, and I have no signal input. What could It be? | [11:06] |
| ........................................... (idle for 3h33mn) | ||
| phk | hverkuil: issue was kernel version (about digital driver), its not working for some kernels
i had to install 5.6.10-050610-generic to make it work FYI | [14:39] |
| .................................................... (idle for 4h18mn) | ||
| Inky1003 | Hello, I sent a message some hours ago about my capture card not receiving the video signal correctly on Linux... can someone please tell me what to do?
there are no errors at all, the capture card just does not decode the video, and thinks actually there is no video. on Windows apparently everything is okay, but... how about Linux? | [18:57] |
| ................................... (idle for 2h54mn) | ||
| hverkuil | Inky1003: try again tomorrow, if I have some time I'll try to help. But I really need to know more: what device (vendor/model) do you have exactly? What input are you using? (composite? S-Video?) Which kernel version? What video format (PAL/NTSC)?
and what application are you using? | [21:52] |
| Inky1003 | I could try again now and bring you the results. I'm with a EzGrabber2 (Mygica, which does have the cx21303 chip), using composite, kernel 5.11 and NTSC, but planning to use PAL also.
PAL-M, in case | [21:54] |
