This is a small mpv script to aid the conversion of videos with PureMPV and pwebm.
The automatically built script can be downloaded from here, or if you prefer building it manually:
git clone https://github.com/4ndrs/pwebm-helper.git
cd pwebm-helper
bun i
bun run buildThe built script will be available under the newly created dist folder.
After this you can put the script in the mpv scripts folder (~/.config/mpv/scripts) for it to run whenever mpv is executed.
The cropping coordinates and timestamps from PureMPV are used and passed to pwebm to either make size limited webms without audio (pressing ctrl + o), or mkvs (pressing ctrl + shift + o) with all streams copied (fonts, subtitles, etc.) except video to keep timestamps accurate. There is an option to burn the subtitles as well when encoding webms that can be toggled pressing ctrl + v.
The following configurations are available when using the ~/.config/mpv/script-opts/pwebm-helper.conf file:
| Option key | Details |
|---|---|
| executable | Specifies which program to execute with PureMPV's parameters. Default is pwebm. |
| params1 | Specifies which params to append when using the keybinding 1. Default is empty. |
| params1 | Specifies which params to append when using the keybinding 2. Default is -c:v libx264 -crf 18. |
| keybinding1 | Specifies which keybinding to use to execute pwebm with params 1. Default is ctrl+o. |
| keybinding2 | Specifies which keybinding to use to execute pwebm with params 2. Default is ctrl+shift+o. |
An example of the content of a configuration file could be the following:
# ~/.config/mpv/script-opts/pwebm-helper.conf
params1=--size-limit 6 --extra-params -map 0:a -c:a libopus -b:a 128k
