svg linked images: rendering images referenced with xlink:href attribute

[swf2d49e at 4wrd.cc]

Hi,

I'm wondering if it was possible to add support for image links in svg files to
ffmpeg? I was trying to use mpv (that uses ffmpeg) to render such linked images
in .svg files directly, but it didn't show any images that were linked via
xlink:href attribute. It only worked when images were base64 encoded (inlined)
directly into svg.

Would this cause a lot of security concerns? This would be an amazingly useful
feature for my workflow at least.

Best,
sven
