Video Postprocessors

Video postprocessors can modify incoming video in several ways. Example usage is following:

uv -p <postprocessor> -d gl

Eg.

uv -p "text:My text"

to annotate incoming video with a text "My text".

You can enumerate available video postprocessors with following command:

uv -p help

border

Border postprocessor allows you to add color border around incoming video. Examples:

uv -p border -d gl

Borders video with default parameters.

uv -p border:color=#ff0000:width=20==8

Creates 8 pixel red border.

text

Note: This module is currently experimental. Requires MagickWand. You can add text to received video using text video postprocess filter. Usage is simply:

uv -d gl -p text:<your_text> <sender_address>

If your text contains spaces, you can enclose entire argument with apostrophes:

uv -d gl -p "text:Your text with spaces" <sender_address>
