See by yourself if this suits you. ;-) I hope it's OK now.

Changes:
- Make ff_query_hwaccel_codec() use codec_id instead of an AVCodec
- Add a "name" field to AVHWAccel struct
- Add "buf" and "buf_size" args to AVHWAccel::start_frame()
- Merge AVHWAccel::start_slice() and ::end_slice() into ::decode_slice()
