Hello,
I am trying to decode H265 frames in hardware (QSV) via ffmpeg (3.4.7) on
Intel CPU. Following command works perfectly on terminal ( OS : CentOS):
* build/lin_x64/bin/ffmpeg **-c:v hevc_qsv -load_plugin hevc_hw **-hwaccel
qsv -i <h265-video-name> -f null -*
I am trying to re-produce similar behaviour via program (C++) to decode
video frames having h265 data but I am unable to find code snippet that
sets (-hwaccel qsv) option via program.
Command above sets 3 parameters :
1. *-c:v hevc_qsv *
codec = avcodec_find_decoder_by_name("*hevc_qsv*");
2.
*-load_plugin hevc_hw * int ret1 = av_dict_set(&opts, "*load_plugin*", "
*hevc_hw*", 0);
and later on passing this to :
int ret2 = avcodec_open2(avctx, codec, &*opts*);
3.
*-hwaccel qsv <Need snippet demonstrating this setting> *
I am not able to set *-hwaccel qsv *via program, need code snippet
demonstrating similar settings (-hwaccel qsv).

Thanks,
Vivekanand
