* lavc/qsvenc: allows the SDK runtime to choose LowPower/non-LowPower modesHaihao Xiang2021-08-12
| | | | | | | | | | | | | The SDK supports LowPower and non-LowPower modes, but some features are available only under one of the two modes. Currently non-LowPower mode is always chosen in FFmpeg if the mode is not set to LowPower explicitly. User will experience some SDK errors if a LowPower related feature is specified but the mode is not set to LowPower. With this patch, the mode is set to unknown by default in FFmpeg, the SDK is able to choose a workable mode for the specified features.

* qsvdec: add support for HW_DEVICE_CTX methodHaihao Xiang2021-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
