The file can be a playlist file as well, a case in which the other command line flags are not used.
You can use a pipe to vooya's stdin, e.g.: cat myfile.xyz | vooya -w 1280 -h 720 --packing p420 --color yuv or cat myfile.y4m | vooya --container y4m On a Mac, you must use the application binary instead of the bundle, like so: cat ./miss_am_qcif.y4m | /Applications/vooya.app/Contents/MacOS/vooya --container y4m Since that is a bit annoying, you can download a wrapper executable and "install" it like so in a Terminal: sudo mv ~/Downloads/vooya /usr/local/bin chmod 0775 /usr/local/bin/vooya Now you can use normal command lines like the above one, without diving into the bundle. Note that for the App Store version only known files are supported; a CLI is not what Apple intended for sandboxing.

(N.b. beta versions prior to 0.9.2 need a final "-" to signal stdin:) cat myfile | vooya -w 1280 -h 720 --packing p444 --color rgba -
