Libavcodec codec-capabilities CODEC_CAP_HWACCEL_VDPAU bit

Question: This probably applies more to libavcodec but if the latest libavcodec with vdpau patch is built (--enable-vdpau option specified), and libavcodec/allcodec.c does register vdpau decoder, why doesnt it autometically see if hardware supports vdpau and set the codec->capabilities CODEC_CAP_HWACCEL_VDPAU bit appropriately? Also it looks like additional enum CodecID has to be generated for VDPAU decoders in libavcodec code.

That's more of a question for the ffmpeg users mailing list.
