hi /g/, vg/tesg here,

We're trying to produce really high quality webms that work with 4chan, so far just a bat script that cuts the video to 4 seconds and uses a fixed bitrate to keep under the file size limit.

It's also really slow even on a near super computer to encode a 4 second webm.... is it possible to use GPU's somehow with the ffmpeg command line?

it says its possible but no where or no program i've tried actually shows my gpu being used

The mission of /ptg/ is to educate everyone - from unwashed иллиterate masses to aspiring students - on matters relevant to closed centralized communities for sensitive autists, aka PT aka private trackers. These matters include but are not limited to: info about liability for actions in and outside the US, internet routing and vpns, cryptography and hashes, security with contexts provided of forum hacks, scams & database leaks, private trackers btfoing etc., likbez on bittorrent, media codecs
we need to work together with neons in order to someone or something to prosper i guess

There's a slight typo in that, it should say Jack OFF To Your Squirrel.
And there have been a number of digital adaptations of board games, most terrible but some good. Pluses are playing against computer players if you're foreveralone, playing against friends over the internet, and automatic enforcement of rules. Minuses are it's always clunkier than actually playing the real board game, inability to create house rules, and these things are always either graphically lame or cringe.

My shitty solution would be to take a screenshot and then crop to what you want to keep, at least it will be in full resolution.
(I say shitty because prnt screen->paste into image editor(gimp)->export as jpg) is not a very streamlined approach.
If youre on linux the screenshot tool lets you screenshot a portion of the screen though, which is sweet.
You could also set it to a keybind.

There is a big push in the low and mid-end audiophile consumer market for class D amps. Boutique internet-only manufacturers as well as big names in the industry are pushing class D products. Class D is simply a cost-savings technique while offering millennials lifestyle boxes to fit on their apartment shelves and desks. The promise of highly efficient, cool amplifiers is a good one -- but so far psychics has got in the way of the dream. So WHY does class D suck?

Lack of bandwidth. Current modules switch at around 500kHz, but some exotic modules like Cherry's parallel modules and Technics' GaNFETs can get up towards 1Mhz. However, that's simply way too little. Class D operates by taking a audio sinewave and modulating it into a square wave, switching at a very high rate, aplifying it, and then rendering it back out to a audio sinewave. Now here where the problem lies; this conversion process leaves behind a lot of noise which must be cleaned up by an output filter -- but due to the limited bandwidth there is very little headroom after the audio band so the filter has to be very aggressive. This aggressive filter messes up the euphonics, a kind of distortion which is hard on the ear-brain system. Our brains hate it. The worst kind of distortion. No matter how low-noise, how good woofer control is, how high the resolution is -- it's going to suck. You're going to quickly dislike the sound. You'll try to convince yourself you like it. You'll try EQ-ing, putting in tube buffers, trying different preamps, etc, but nothing will fix it.

So, class D sucks. If you see class D, immediate look elsewhere.

You have some basic knowledge of sound and from that you intuit things you're not educated on. It seems straightforward to you, but your straightforward understanding is wrong. We're discussing switching bandwidth of a pulse width modulator, but audio bandwidth. Now, higher bandwidth amps sound better -- why I don't claim to know. Faster rise times? Some kind of non-linearity? But that's a separate topic. When a class D's low pass output filter does it's thing, it doesn't have enough headroom to avoid getting artifacts into the audio band. Let's look at it another way:

DSD-64 is considered to be too noisy, and DSD uses a square wave modulation that is similar (though not the same) to class D's PWM stage. DSD-64 samples (switches) at 2.8 MHz. Most modern class D PWM switches at around 500 kHz. The higher the sample rate of DSD, the further up the frequency band quantization noise is pushed. DSD isn't considered to be good until at least DSD-128 or optimally DSD-256, which is 11.3 MHz. As we can see, class D is way, WAY to slow. Even the very best class D that I know of, Cherry's top of the line amp, has a switching bandwidth of 2 MHz, which is less than the already too-low DSD-64.

installed buster standard without DE
installer detects wifi, downloads everything fine.
first reboot looks good.
try to run updates and install some apps
oops wifi isnt enabled.
try ifconfig, iwlist, iwconfig; ooops none of those commands are available anymore
figure out how to "enable" the wifi adapter anyways and "connect" to the network. still no IP, cant download anything.
find the source code for new drivers from a website, download it from my laptop and try to compile it via make instructions... "ERROR 2" blah blah.
got tired of this. turn off the computer to take a break.
later turn computer back on to resume trouble shooting.

not a healthy approach into learning linux if you're copying and pasting something. Maybe check the man page of commands theyre running, or the date of the post - some utilities are likely depreciated.

might have to give that a try. thanks for the link.

>>78975237
for sure, its not the best way to learn, but I didnt want to look too much into commands if they werent available anyways. most of the pages i was reading from were within the past 1-3 years, but there wasnt really much that helped except for one site. all the ifconfig, iw..., nmcli commands every site referred to wasn't part of the install or no longer available.

Extremely low power illumination.

I am looking for a way of illuminating a 400sq foot room, just sufficiently enough to navigate and identify objects and obstacles, with the least amount of power possible.

I noticed that pointing a cheap 5mw green laser pointer straight up at a white celling in a completely dark room, that illuminated the room sufficiently to meet my requirements. The problem I encountered was the diode would dim within minutes and eventually fail.

Where can I find a 5mw green laser diode that can be run continuously and survive at least 1000 hours?
