Re: [gentoo-user] Screenrecording with audio from firefox
Yes, I realize it might not have been clear, as I got a bit confused by my own
thought process as well.
I will also answer in pieces related to your questions

The crash might be due to it not getting exclusive access to alsa or the sound
card not properly selected. Yes that configuration is for alsa -> jack -> obs/
simplescreenrecorder

Here I actually meant "using the first config file will force alsa native
programs to connect to jack. Incidentally, the second solution will (usually)
also work for alsa as it would do "alsa -> pulseaudio -> jack -> obs/
simplescreenrecorder", which is my default as I'm more accustomed to
pulseaudio and jack (some programs like Discord really want pulseaudio)

Well, I will make sure it eventually works one way or another :) as I know how
frustrating sound can be sometimes. As I said, I create music, as such I want
Jack, but I also want to watch youtube without having to tear down my music
setup. And I stream from time to time, so I use Jack/Alsa/Pulseaudio all at
the same time and have picked up some things along the way.

Were they used for swap? How are they connected? The dmesg you sent in the other email makes me think the SSDs are connected to old ATA ports as they mention UDMA instead of Sata speeds. I would definitely suspect: - the drives (incl. SSDs) - other hardware (incl. the disk controller(s)) - memory - PSU As the issue is recent and intermittent, either a recent addition is causing issues, or there is a timing issue occuring during boot. And these can also occur during kernel initialisation. An initramfs with failover to a simple shell could help here as then you can get a dmesg of when the init fails. There is a kernel commandline option that forces the kernel to wait an X amount of time before trying to access the root-partition and starting "init". This is usually needed for USB-boot, but might also be necessary when disks take a bit longer to initialize. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

*Whoa*
I just remembered, that I tested back on 5.14.2[1], but, I just
re-emerged qtcore-5.15, qtwidgets-5.15 and qtgui-5.15 (which is all
cadence needs) and qtsvg-5.15 (for qt5ct that is called when running
stuff) and my hack still worked, i.e. it compiles fine and
cadence-xycontroller even runs (which is where that pixmapdial.cpp
ends up in) ;)

I think something similar was on this list a couple of days ago, it's
a missing include (that wasn't neccessary before Qt5.15), there's 21
similar bugs filed already c.f.[1].
A quick and easy fix for this problem should be this:
1. create a file /etc/portage/env/missing-qpainterpath-flags and insert
this line:
CXXFLAGS="${CXXFLAGS} -include QPainterPath"
2. add the line
=media-sound/cadence-0.9.0-r4 missing-qpainterpath-flags
to /etc/portage/package.env (or /e/p/package.env/qpainterpath.env or
some such if you've "directoryfied" your package.env (can you?) ;)
[add more lines for specific package versions and revs for the same
problem, see [1] for candidates]
Yes, that is *quite an ugly hack*, but could be handy while stuff get's
patched to work with that specific change of Qt5.15...
FWIW: that includes that QPainterPath header in _all_ C++ sources, but
what the hey, compilers are so good today, that they throw away
anything unused, so it should not matter. It'll slow down the compile
a bit...
Once e.g. media-sound/cadence is fixed and revbumped/versionbumped,
delete that line from package.env.
It works here for a quick:

Re: [gentoo-user] Kernel panic - not syncing: No working init found.
Yes, you do need to capture the kernel output. The usual way is to hook up a serial cable to another computer and pipe the output to it. You interrupt the boot (usually by hitting or in GRUB), and then edit the kernel command line thus: console=tty1 console=ttyS0,115200n8 If you can do that you can give us some debug output. - Matthew

The above setup is for alsa/jack/obs...right.
Since jackd does not start (it crashes) and I am currently not in
the mood to fix an error which helps to fix a problem which should
fix a problem for an application which in first place was there to
help me to fix an issue to record from Firefox...I will try
pulseaudio -- despite the fact, that I really don't like it.

Re: [gentoo-user] Screenrecording with audio from firefox
It might be that your Qt5 is perhaps partially updated or out of date even,
but not sure. I do know that it can be a pain to compile due to Qt5 changing.
If it's too much of a hassle to get it to work, Catia could be replaced by
QJackCtl, however then you will need to have the tweaks Cadence does for you
manually applied. Which, according to my system, is:
pcm.!default {
type plug
slave { pcm "jack" }
}
pcm.jack {
type jack
playback_ports {
0 system:playback_1
1 system:playback_2
}
capture_ports {
0 system:capture_1
1 system:capture_2
}
}
ctl.mixer0 {
type hw
card 0
}
( In case you want to entirely not bother with pulseaudio )
Or, like me where I have it set to pulseaudio mode which creates:
pcm.!default {
type plug
slave { pcm "pulse" }
}
pcm.pulse {
type pulse
}
ctl.mixer0 {
type hw
card 0
}
This would go into a file .asoundrc in your $HOME and force ALSA native
programs to actually hook up as Jack clients, so you can manage your audio.
Note that you would still need to go into QJackCtls settings to setup the
correct main audio device

Re: [gentoo-user] Screenrecording with audio from firefox
I'm not entirely sure if it's part of portage yet (long time since I touched gentoo) but it's a modern jack routing program in similar style to the cadence program. If cadence exists, it's likely bundled with catia otherwise it can be found in the audio overlay, this issue specifically mentions it: https:// github.com/gentoo-audio/audio-overlay/issues/47 On Wednesday, June 3, 2020 4:17:15 PM CEST tu...@posteo.de wrote: > Hi Daniel, > > short question...what is catia (beside a CAD program by Dassault > Systems... ;)... > Can't find that in portage... > > Cheers! > Meino > > On 06/03 03:47, Daniel Sonck wrote: > > I just installed simplescreenrecorder as well.

Re: [gentoo-user] Screenrecording with audio from firefox
I just installed simplescreenrecorder as well. The same pulseaudio method should also work for that by choosing the "Monitor" variants, although I have to add that it would not allow you to capture both a mic and firefox (or other application at the same time) unless you play back your own microphone sound. With OBS you can add an Input and Output source to have both mic and desktop audio. If you want to have more control or are reluctant to use pulseaudio (as some are) then it gets more complicated. With ALSA, I know there are ways to support it by editing the ALSA configuration file but I don't know anything about that (nor do I really like that approach). I would then recommend using JACK instead, and setup ALSA programs to use a wrapper for JACK, this would allow you to route any audio through anything (for which people in Music as I am use Jack) including mixing it together before sending to SimpleScreenRecorder or OBS. The 2 tools I recommend to add would be cadence (for configuring Jack + ALSA) and catia (to setup the proper audio routing) possibly combined with some jack audio mixer to get a "virtual mixing panel". Hope this helps Regards, Daniel On Wednesday, June 3, 2020 3:30:53 PM CEST tu...@posteo.de wrote: > Hi, > > To record my screen with audio I installed > obs and then simplescreenrecoder. > > Recording the video stream more or less works (I cannot record a > firefox-window and need to record the full screen). > > But recording the audio from the source which will be replayed > by firefox only give me a stuttering sinus tone. > > According to different tutorials I watched the recording of > a gameplay works with video/audio which exactly mine setup. > > Interestingly I cannot find the regarding options of both > screen recorders any more (the tutorials refer to older versions > of the recorders). > > How can I record video and audio from the played source nonetheless? > > Cheers! > Meino
Re: [gentoo-user] Screenrecording with audio from firefox
Hello, For OBS you can use the Audio Output Capture which requires PulseAudio to be running. It will look for the monitor device of your current soundcard to capture all audio you hear. For simplescreenrecorder, I don't know as I prefer OBS for it's extra compositing features and convenience.

[gentoo-user] Screenrecording with audio from firefox
Hi, To record my screen with audio I installed obs and then simplescreenrecoder. Recording the video stream more or less works (I cannot record a firefox-window and need to record the full screen). But recording the audio from the source which will be replayed by firefox only give me a stuttering sinus tone. According to different tutorials I watched the recording of a gameplay works with video/audio which exactly mine setup. Interestingly I cannot find the regarding options of both screen recorders any more (the tutorials refer to older versions of the recorders). How can I record video and audio from the played source nonetheless? Cheers! Meino
