Minimalism Tips

MiyoLinux · 2021-04-06 14:22:55

More ffmpeg minimal minimalist minimalism...

Don't use a bloated screen recorder like Simple Screen Recorder, OBS, etc...

Just use ffmpeg to record your screen and alsa to record the audio at the same time...

This is the command that I use; adjust it to your needs , because I have alsa set to use my USB microphone default:CARD=U0x46d0x825, my screen size -video_size 1366x768, frame rate -r 15 etc...

ffmpeg -y -f alsa -i default:CARD=U0x46d0x825 -f x11grab -r 15 -video_size 1366x768 -i :0.0+0,0 -c:v libx264rgb -preset ultrafast ~/Videos/output.mkv

If you're not sure how to find your USB microphone (if you use one), use this command to find it, then exchange your "card" in the command...

arecord -L

If you are only interested in keeping your screen from turning off, don't use a bloated power manager or screen saver...just add this to your autostart...

xset s off && xset -dpms

^ Multiple options can be combined in a single command:

xset s off -dpms

HEY! Don't be minimalizing my minimalism!

Bwahahahaha!

Don't use a bloated volume icon on your panel ; just use the volume keys on your keyboard.

Here's what I have in my Openbox rc.xml file; adjust it to the needs of your WM/DE. By the way, this is for alsa-only...

    <keybind key="XF86AudioRaiseVolume">
      <action name="Execute">
        <command>amixer set Master 5%+</command>
      </action>
    </keybind>
    <keybind key="XF86AudioLowerVolume">
      <action name="Execute">
        <command>amixer set Master 5%-</command>
      </action>
    </keybind>
    <keybind key="XF86AudioMute">
      <action name="Execute">
        <command>amixer set Master toggle</command>
      </action>
    </keybind>

Actually those commands will also work for PulseAudio (or PipeWire). But that's not very minimal

Thanks. I didn't know that since I don't use them. Could've sworn I saw different execute command for pulse at some point.

Thanks HoaS.

Actually, moc seems to be the lightest way to play audio that I know of.

ffplay is way more cpu usage intensive in my findings... heh.

I use the same/similar for dwm. But i dont need the percentage sign, not sure if that is due to my wm or yours?

static Key keys[] = {
        /* modifier                     key        function        argument */
        { 0,                    XF86XK_AudioMute,                  spawn,          SHCMD("amixer set Master toggle")},
        { 0,                    XF86XK_AudioRaiseVolume,           spawn,          SHCMD("amixer set Master 5+")},
        { 0,                    XF86XK_AudioLowerVolume,           spawn,          SHCMD("amixer set Master 5-")},

cmus may be lighter, not sure havent tested.

andyprough · 2021-04-09 02:51:48

I wonder if apt is bloat. I'm sure it is to a certain extent. Would the system allow you to uninstall apt and aptitude and dpkg? Then just build stuff from source. Would you still have Devuan at that point?

I'm going to try 'sudo apt purge apt aptitude dpkg' in a Devuan vm and see what happens... And really sudo is bloat too when you think about it, so I'll try 'sudo apt purge apt aptitude dpkg sudo' just for kicks.

Update: Nope, does not work.

Yes, big difference. Just played the same song with each - top showed moc using 1.4% cpu, and ffplay using 8%-14%. ffplay is bloat.

Quick ps_mem comparison:

  1.0 MiB +   2.1 MiB =   3.1 MiB       aplay
  7.5 MiB +  24.2 MiB =  31.7 MiB       mocp (2)
 38.6 MiB +  67.5 MiB = 106.0 MiB       ffplay

aplay ftw!

dice · 2021-04-09 15:17:02

cmus comes in below mocp but aplay FTW.

ps_mem.py -p 26253                                                                                               
 Private  +   Shared  =  RAM used       Program

 19.7 MiB +   5.5 MiB =  25.2 MiB       cmus
---------------------------------
                         25.2 MiB

Perhaps we need a "Tips for Low Resource Usage" thread? LOLOL!

I guess minimalism means different things though. My idea behind it was tips for using less (or unneeded) applications.

The new thread request was a joke. Lots of great info here! Thanks everyone....keep it coming.

Head_on_a_Stick · 2021-04-09 16:05:26

On my hardware:

  1.7 MiB +   2.8 MiB =   4.5 MiB       mpg123

This is a 16GiB machine so Linux grabs all the memory it can for applications. I presume anticapitalista & dice have less memory available.

EDIT: death to MP3! Lossless compression ftw!

Nice!

Different machines will give different results. I boot Miyo-Rolling x86_64 on my laptop, and it boots at 180 MBs of RAM. Same exact setup boots on my old HP dx5150. desktop at 130 MBs of RAM.

We need a new "How to get the same results on every computer" thread.

That's just a container — it can hold either lossy (bad) or lossless (good) CODECs. OggPCM is one of the better options and carries the official HoaS stamp of approval™

EDIT: Leftfield, nice!
