I don't see any real advantage whatsoever for this, the few kB saved are not of much advantage, especially as they are only saved on developer systems. Also, VDPAU as an API can most certainly work on Windows if one wanted it to. In fact, it will probably compile just fine at the least under cygwin (even if there is not backend implementation). Lastly, if you remove a header it will also break programs that try to use runtime detection e.g. via dlopen or other mechanisms to figure out if the feature exists or not, and they suddenly have to check at compile time instead. The last part IMHO makes that this is in fact just wrong to do. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
