[FFmpeg-devel] [PATCH] avfilter/vf_drawbox: remove redefinition of DrawBoxContext typedef

[James Almer]

Old GCC and Clang apparently don't like it.

Untested since i don't have old compilers.

Clang 3 even says "redefinition of typedef 'DrawBoxContext' is invalid in C", but newer
Clang compiles it fine.
