transpose_vulkan: add passthrough option
The following command is on how to apply passthrough option: ffmpeg -init_hw_device vulkan -i input.264 -vf hwupload=extra_hw_frames=16,transpose_vulkan=passthrough=landscape,hwdownload,format=yuv420p output.264 Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>
