vt-enc is a bash script that simplifies the process of encoding videos with FFmpeg using Apple's VideoToolbox framework on macOS. It provides an easy-to-use command-line interface for encoding videos with various options, including codec selection, quality settings, and scaling.
I don't use VideoToolbox or Mac, so won't test it. But looking at the script, it looks clean and nice Bash scripting. I like it. Nothing serious but one thing I would suggest is for just a little bit easier and cleaner look in the code, to use cat with EOF for the help, like in one of my scripts:
help_options() {
cat %%EOF
options:
-h show help and exit
-H show all options, notes and exit
-m HEIGHT max height
... (and more)
EOF
}
Edit: I forgot that beehaw does not like the character for < and will destroy everything. So I changed them to %%, just replace it with the less than character, the opposite of >.
Another Edit: In your build sh script, I like you hardcode rm -rf ffmpeg_vt, and don't use a variable for. And also checking if its a directory and exit if it can't cd into cd ffmpeg_vt/ || exit 1 . Well done.
Within cat EOF syntax you can just use variables and commands as well. Just tested it and I see the problem here. The EOF syntax will not interpret the backslash and print them literally. So those variables would require to be interpreted with echo -e first. I never used colors in this syntax before. It's up to you which syntax you prefer, some people still like the series of echos over cat EOF.
