The patch in attachment implements a HWAccel module that uses the Video Decoder Acceleration framework on Mac OS X. VDA decodes H264 avcc format video in GPU.
The technical notes from Apple about this module can be found at this link :

The VDA HWAccel module sends the bitstream to the decoder and the decoder callback maintains a queue of decoded frames ordered by presentation time.
The client of this module get decoded frames from the queue.

I'll share a client implementation for VLC on videolan mailing list.

Best regards,
