How about to use the same macro for all QSV decoders? Compared
ff_mpeg2_qsv_decoder in qsvdec_other.c and ffmpeg_h264_qsv_decoder in
qsvh2645.c, besides x, X, bsf_name, option and priv_data_size are different too.
So we may define a macro below in qsvdec.h and use this macro for all QSV
decoders.
#define DEFINE_QSV_DECODER(x, X, bsf_name, option, priv_data_size) \
...
Thanks
