FFmpeg now support librsvg support for SVG rasterization.

I have tried the following command:

But I get the

Answer 1

Your ffmpeg needs to be compiled with --enable-librsvg. If you're compiling ffmpeg then you need to install whatever package provides the librsvg header files. For example, in Arch Linux it is librsvg, and in Ubuntu it is librsvg2-dev.

Series of images

Usage is similar to using raster images as inputs with the image demuxer. For example, a series of images named vector-001.svg, vector-002.svg, vector-003.svg, etc:

ffmpeg -i vector-%03d.svg -vf format=yuv420p output.mp4

Single image

ffmpeg -i input.svg output.png

With custom size:

ffmpeg -width 600 -i input.svg output.png

-keep_ar true is the default, so it will automatically calculate height in this example to preserve the aspect ratio.

Decoder specific options

The decoder librsvg has a few input options:

$ ffmpeg -h decoder=librsvg
  […]
  -width             <int>        .D.V...... Custom width to render to (0 for default) (from 0 to INT_MAX) (default 0)
  -height            <int>        .D.V...... Custom height to render to (0 for default) (from 0 to INT_MAX) (default 0)
  -keep_ar           <boolean>    .D.V...... Keep aspect ratio with custom width/height (default true)
