# Configuration information for video process test case.
# This application will firstly load yuv frames to one type of surface(NV12/YV12/I420)
# you require. After video processing, the processed content (NV12/YV12/I420 surface)
# will be stored to frames(yv12 format in file).
# Supported features include scaling and implicit format conversion(NV12<->YV12<->I420).
# you can modify this configuration file to set the corresponding parameters.

#1.Source YUV(RGB) file information
SRC_FILE_NAME: ./bigship_1280_720p_25fps_10frames_writer1280x720_noised.nv12
SRC_FRAME_WIDTH: 1280
SRC_FRAME_HEIGHT: 720
SRC_FRAME_FORMAT: NV12

#Note .nv12 files are in NV12 format
SRC_FILE_FORMAT: NV12

#2.Destination YUV(RGB) file information
DST_FILE_NAME: ./scaling_out_720x1280.nv12
DST_FRAME_WIDTH: 720
DST_FRAME_HEIGHT: 1280

#3.How many frames to be processed
FRAME_SUM: 1

#4.How to use this template
