- The drawvg filter in FFmpeg, introduced in version 8.1, renders vector graphics on video frames using the Vector Graphics Script (VGS).
- VGS is a concise, domain-specific language inspired by Magick Vector Graphics, SVG's <path>, and PostScript, designed for 2D graphics rendering with Cairo.
- VGS supports FFmpeg expressions for dynamic graphics, enabling calculations based on frame dimensions, metadata, random values, and pixel colors.
- Examples of drawvg applications include creating a progress indicator, utilizing frame metadata for cropping, and implementing custom transitions like circlecrop.
- The filter can also be used for effects such as pixelization with rhombuses and generating waves by combining with the displace filter.
- Scripts are documented in the language reference, and a playground offers a gallery of examples showcasing VGS capabilities.
