[FFmpeg-devel] [PATCH] avcodec/librsvgdec: fix compile error when librsvg < 2.52

[Lu Yao]

When compiling with an earlier version of lbrsvg, the following error
occurs：
  "src/libavcodec/librsvgdec.c: In function 'librsvg_decode_frame'"
  "src/libavcodec/librsvgdec.c:93:5: error: 'viewport' undeclared"

Fixes: 86ed68420d3b ("avcodec/librsvgdec: fix memory leaks and deprecated functions")
