Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:
ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
-crf values can go from 4 to 63. Lower values mean better quality.
-b:v is the maximum allowed bitrate. Higher means better quality.

To convert a part of a video file:
ffmpeg -i your_video.mkv -ss 00:00:10.000 -to 00:00:20.000 -c:v libvpx -crf 4 -b:v 1500K -vf scale=640:-1 -an output.webm

-ss is the start position in number of seconds, or in hh:mm:ss[.xxx] format. You can get it using your video player (Ctrl-G in MPC-HC).
-to is the end position.
-vf scale=640:-1 sets the width to 640px. The height will be calculated automatically according to the aspect ratio of the input.
-an disables audio. 4chan will reject your files if they contain audio streams.

ffmpeg documentation: https://www.ffmpeg.org/ffmpeg.html

Current limits for WebM files on 4chan are:
Maximum file size is 3072KB.
Maximum duration is 120 seconds.
Maximum resolution is 2048x2048 pixels.
No audio streams.

/g/ I need your help, I keep getting this fucking shit and I have done everything I can think of to fix it but to no avail. It's a red block of white text that appears when I enter a thread here on 4chan and it seems to prevent new replies from being listed numerically in the tab as 4chan x normally does. This is what it says:

"Unread" initialization crashed.
[Exception... "<no message>" nsresult: "0x805e0006 (<unknown>)" location: "JS frame :: file:///C:/Users/Owner/AppData/Roaming/Mozilla/Profiles/yxf97b4q.Owner/gm_scripts/4chan_X-1/4chan-X.user.js :: $.ajax</< :: line 318" data: no]

I've reinstalled the script mutiple times, cleared cookies and the like, to no avail and it is really starting to bug me a lot. Google was not of help in this issue, nor was searching on my part to find the issue. I'm at a total loss. What in the world is the issue here and how do I fix it?

Daily reminder that:
OSX = Linux that can install Adobe Photoshop and all cool programs from Windows and still looks beautiful out of the box.

Prefer a hackintosh intead of installing a Loonix Distro.

Just gonna leave this here

Let's get some coding practice, /g/. Roll and code, ladies and gents.

Oh man, they did it again.

Fuck you, GNOME.

Hey /g/

Which is superior in terms of performance and security between BitLocker, PGP, and Truecrypt? What are the pros and cons to using each?

I'm not looking to keep the NSA out of my shit or anything, I'm just looking to protect my data from petty thieves and hackers.

Please contain your stupid questions to this thread.

Don't know what this got taken down before but...

I live with my sister and my parents in my house, and I pay all the bills and own the router and crap. They are all on my phone plan.

My sister is an annoying SJW, but I can't kick her out because she's mentally I'll and my parents would be very upset. So, to alleviate this stress, I've taken to blocking tumblr from my router. This is working fine, but she can still access it from her phone. Now, I would kick her off my plan, but then my parents would just buy her a plan, so that wouldn't work.

Is there any way I can block access to tumblr on my cellular data plan?
