[FFmpeg-devel] [PATCH] lavc/qsvdec: hw device should be set

[Zhong Li]

Add the flag "AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX" to indicate
AVCodecContext.hw_device_ctx should be set before calling
avcodec_open2() for qsv decoding.
It is consistent with examples/qsvdec.c.

It also can make function "hw_device_match_by_codec()" can find qsv
device successfully.
