in a distro you could have libavfilter-dev and yet not libavcodec-dev. it wouldnt work, we dont have 4 independant configure scripts, and quadruplicating the build system across 5 split -dev packages seems like a bad idea and if you meant the distro simply physically removd libavcodec. We should nozt support this castration and if someone still wanted he can leave the header there as well if he already manually cuts things randomly away [...] #ifndef AVCORECOLORSPACEH #define AVCORECOLORSPACEH The enums are not just colorspace related some enums are related to the positions of samples. if at all this could be moved into teh main public header of avcore [...]

In the interest of progress, please allow me to sidestep this question (and the opt.h question) as follows: 1) For now, I will include avcodec.h in avfilter.h; if the color rendering enums are moved out, only this line would need to be changed. 2) I will encode colorprimaries, etc. into the args' string currently_ _being passed to the vsrcbuffer init routine, which will now expect 10_ _colon-separated arguments rather than 5. This affects only the buffer' filter.

I think there is agreement to place the 5 enums into the AVFilterLink structure.

I would try to place them in AVFilterBufferRefVideoProps, if it works its more flexible
