This guide contains the command to automatically set up the mediamtx streaming server on your Raspberry Pi for the webcam upgrade project.
Before you run this command, please ensure:
| # --- Configuration --- | |
| AUDIO_FILE = 'Your MP3 File.mp3' # <<< CHANGE THIS TO YOUR AUDIO FILE (can be .wav or .mp3) | |
| TARGET_SR = 12000 # Target sample rate, best to choose from [8000, 11025, 16000, 22050] (lower = less data, 16k is probably the best for its size, but still can reach the 5MB graph size limit, you can use 10000 or 9000 too.) | |
| N_PARTIALS = 30 # Sine waves per frame (higher = more detail, more accurate, a bit more noisy) | |
| GAIN_DIGITS=3 # Number of decimal places for gain values (higher = more precise, but bigger graph size) | |
| N_FFT = 1024 # FFT window size (advanced, don't change unless you know what you're doing) Default: 1024 | |
| HOP_LENGTH = 256 # Samples between frames (also advanced) | |
| MAX_LIST_SIZE = 9999 # Max items per list (DO NOT CHANGE) | |
| GAIN_SCALING_POWER = 1.0 # Compress gain dynamics (0.5 is sqrt) (turn up to 0.7-1.0 if the resulting graph is not clear) |
| javascript:(function() { | |
| var relativeTimeElements = window.document.querySelectorAll("relative-time"); | |
| relativeTimeElements.forEach(function(timeElement){ | |
| timeElement.innerHTML = timeElement.innerHTML +" -- "+ timeElement.title; | |
| }) | |
| }()) |
