This allows user set hw_device_ctx instead of hw_frames_ctx for QSV decoders, hence we may remove the ad-hoc libmfx setup code from FFmpeg. "-hwaccel_output_format format" is applied to QSV decoders after removing the ad-hoc libmfx code. In order to keep compatibility with old commandlines, the default format is set to AV_PIX_FMT_QSV, but this behavior will be removed in the future. Please set "-hwaccel_output_format qsv" explicitly if AV_PIX_FMT_QSV is expected. The normal device stuff works for QSV decoders now, user may use "-init_hw_device args" to initialise device and "-hwaccel_device devicename" to select a device for QSV decoders. "-qsv_device device" which was added for workarounding device selection in the ad-hoc libmfx code still works For example: $> ffmpeg -init_hw_device qsv=qsv:hw_any,child_device=/dev/dri/card0 -hwaccel qsv -c:v h264_qsv -i input.h264 -f null - /dev/dri/renderD128 is actually open for h264_qsv decoder in the above command without this patch. After applying this patch, /dev/dri/card0 is used. $> ffmpeg -init_hw_device vaapi=va:/dev/dri/card0 -init_hw_device qsv=hw@va -hwaccel_device hw -hwaccel qsv -c:v h264_qsv -i input.h264 -f null - device hw of type qsv is not usable in the above command without this patch. After applying this patch, this command works as expected. Reviewed-by: Soft Works <softworkz@hotmail.com> Signed-off-by: James Almer <jamrial@gmail.com>pull/364/head
