I try to run them separately with &&, ffplay doesn't open. I try with different terminals, I get "resource busy". I don't know what else you mean by that. Your advices are not useful, and what I ask couldn't be more simple but this program apparently is $h|T on that specific, simpl...

Logically the closest I could up with is: ffmpeg -f v4l2 -i /dev/video2 -framerate 30 -video_size 1280x720 -c:v utvideo -f tee -map 0:v "[f=nut]essai.nut|[f=data](ffplay -)" But ffplay doesn't open.
same result with other container than data.
Please, I'm close !

Hi. Here's my problem: the person that will be recorded needs to see himself while at it. So it's the issue of monitoring in real timeI found that using the tee pseudomuxer seems to be the simplest and most straightforward. The tee muxer can be used to write the same data to several outputs, such as...

I'll create a new thread for the monitoring issue.
THANKS YOU LOT.

Yep, now it's in utvideo format, I got my humongus file size that I like ! Whether or not kdenlive will tolerate a 2 Go file is another issue. Last issue: how do I redirect ffpmpeg result to standard output AND a file as usual ? In real time ? It does not feature the normal > < redirection syntax. A...

The finest options I could settle on are: root@debian /h/m/Images# nice --20 ffmpeg -f v4l2 -framerate 30 -video_size 1280x720 -input_format mjpeg -i /dev/video2 -crf 0 -preset ultrafast here.mkv I read presets don't change quality, only crf does, and I want lossless. No lagging. excellent. one issu...

Interesting, thanks ! It seems to work but... almost completely white, are you sure there is nothing lost in reducing the luminosity afterwards instead of from a GUI ? https://i.im.ge/2021/09/23/TCwkB9.png And the focus fonction is lost: it seemed to me that it's a mechanical control of the camera, ...

guvcview Hi. The issue is not with debian per se, but I don't know where to ask so... I have a camera (logitech, luckily, linux should fare well) and my computer isn't top notch. I wished to use guvcview to record at highest resolution (1280x720) at 30 fps. the quality is enough for me. But I must a...

no I didn't do anything but using the installer and grub-install. More is terra incognita to me. I try booting from that disk , and had big issues, from two computers. I quit, now I'll focus my attention on opening the (encrypted) original SATA hard disk of that PC, which before worked like a charm....

having reinstalled now grub boots but shows 2 "debian gnu-linux"
each one giving "loading linux 5.10.0.8
incorrect magic number ELF independant of architecture
loading initial ramdisk
incorrect magic number ELF independant of architecture

I try the rescutux again on that.

I tried both programs. Of course nothing worked at all.
I even tried installing linux mint... the cute desktop pops up but the installer won't even open.
I'll try with the "good" image once again, and then f**k it I'll do without that PC.

And I tried before all of that on another hard disk... wouldn't even see it as bootable in the first place. Tell me what are the odds that all of that happens in a row ? my hope lies in repairing the disk's GRUB. I tried grub-install to no avail. (Of course sdb is how the disk with the failed instal...

I downloaded the image on https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/ verified the checksum. burnt it with dd (then sync) on two or three usb sticks, verified THEIR checksums. It went through the installation, installed GRUB, But then it couldn't boot, as explained. Then I reinstalle...

now I'm trying to install on another stick, from another stick, same image though. If it fails, then debian has a serious "stable" problem.

Hi. I've just installed bullseye on a hard disk. it went well, and booted, then: error: file '/boot/grub/i386-pc/normal.mod' not found grub rescue> then on another machine I plugged in the hard disk, did "update-grub; grub-install /dev/sdb" and when rebooting on the disk it went: no such d...

The problem wasn't with the computer, since I tried installing two times with debian, same thing, while with Mint it went ok. I guess debian installer wasn't good, or somethin', though the integrity check showed nothing.
God knows what it was, but another distribution got the better end...

Hello. I'm not new with linux nor debian and usually I can work my way around myself, as long as I'm the source of the problem. I installed debian sid through a netinst (64b amd64, the computer is B50-10), checked the usb stick image integrity, it was fine, then went along with the installation, cho...

Okay, I'll reinstall, I knew it was the only solution anyway. Sure, the packages are a mess.
I'll tell you then if there's still that problem at startup, of with sensors-detect.
Nonetheless, thanks !

I've no tried cleaning the fan for some weeks, but the fan works. Last time I removed the fan and cleaned everything. I suppose there's nothing more to do. I don't remember having ever touched /etc/modules. it87 means nothing to me. Honnestly, given the tower wasn't hot the last times it shutdown, I...
