Simple WebM maker for mpv, with no external dependencies.
Place this in your mpv scripts folder. By default, the script is activated by the W (shift+w) key.
Follow the on-screen instructions. Encoded WebM files will have audio/subs based on the current playback options (i.e. will be muted if no audio, won't have hardcoded subs if subs aren't visible).
You can configure the script's defaults by either changing the options at the beginning of the script, or placing a webm.conf inside the script-opts directory. A sample webm.conf file with the default options can be found here. Note that you don't need to specify all options, only the ones you wish to override.
Building requires moonc, the MoonScript compiler, added to the PATH, and a GNUMake compatible make. Run make on the root directory. The output files will be placed under the build directory.
