OK. Here are the results from nightly build, first is Direct3D:
main debug: picture in 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture user 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture out 640x272 (0,0,640x272), chroma YUY2, ar 101647:43200, sar 1:1
main debug: looking for video filter2 module: 19 candidates
swscale debug: 640x272 chroma: I420 -> 640x272 chroma: YUY2
main debug: using video filter2 module "swscale"

blend debug: chroma: YUVA -> YUY2


and then OpenGL:
main debug: picture in 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture user 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture out 640x272 (0,0,640x272), chroma RV32, ar 101647:43200, sar 1:1
main debug: looking for video filter2 module: 19 candidates
swscale debug: 640x272 chroma: I420 -> 640x272 chroma: RV32
main debug: using video filter2 module "swscale"

blend debug: chroma: YUVA -> RV32


And one from 0.8.6 using OpenGL:
main debug: picture in 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture user 640x272 (0,0,640x272), chroma I420, ar 101647:43200, sar 1:1
main debug: picture out 640x272 (0,0,640x272), chroma RV32, ar 101647:43200, sar 1:1
main debug: looking for chroma module: 9 candidates
main debug: using chroma module "i420_rgb"
