Running on x86_64 (virtualized). I've had a chance to narrow it down a bit.
Seems like I420->BGRA is indeed quite fast. The same can't be said, however,
for BGRA->I420 (with hotspots in
video_converter_matrix8_table/video_chroma_down_h2_cs_u8), or I420->BGR (with
hotspots in pack_BGR/video_chroma_up_h2_cs_u8).
