USB Video Capture with FFmpeg

This guide explains how to capture video and audio from a USB capture device and process it using FFmpeg in two steps. The current method captures video at a custom frame rate with sound, followed by a second step to process the video.

Step 1: Capture Video and Audio

The first command captures both video and audio using a USB video capture device and a virtual audio source. It records the video at 34 frames per second for 200 seconds.

ffmpeg -f dshow -rtbufsize 100M -i video="usb video" -f dshow -i audio="virtual-audio-capturer" -preset ultrafast -framerate 34 -t 200 -y output2.mp4

SSL Certificate Generation Script

This script generates a self-signed root CA certificate and a server certificate using OpenSSL. It also includes subject alternative names (SANs) for custom DNS entries. The commands are structured to create certificates valid for 100 years (36500 days).

Steps:

Define Subject for Certificates: The suj variable defines the subject for the certificate.
