Per questo motivo avevo scritto uno script wrapper interattivo per desktop unix e, dopo un anno di utilizzo, sono felice di condividerlo lì!
Realizzato con byzanz, gifsicle, xdotool, e lo script è scritto in php.
Esempio di output:
[1020px, larghezza gif non ridimensionata 1020px, 70 secondi, 50 colori, 65Kb ]
Fornisce buone gif compresse ed è una buona vetrina per questa domanda.
Questa è una base abbastanza semplice, pronta per essere hackerata da te.
Funzionalità : registrazione GIF a posizioni del mouse o a schermo intero, ridimensionamento, compressione, compressione colore, inversione / unione, caricamento arricciatura giphy.com.
Per avviare un record gif di 10 secondi: gif 10
Per registrare più volte con gli stessi parametri: gif !
Per avviare un disco gif di 5 secondi a schermo intero: gif 5 --fullscreen
Script runnning, registrandosi piacevolmente:
[ 45 secondi, larghezza 645px, colori pieni, 976kb ]
Script completo da 5kb:
#!/usr/bin/php
<?php
#> php xdotool byzanz gifsicle curl
#@ https://webdev23.github.io/gif/gif
echo "Usage: ./gif [time in seconds|!] [--fullscreen|-f]\n";

echo "Gif recorder tool\n";
echo "gif ! to call back last settings\n";
echo "Please move your mouse at the top left corner point\n";
echo "of the wanted gif area. Then press enter.\n";
echo "\n";
