Detailed Description

Video changed decoded frame information.

Each parameter are indicated as the figure below.
The 'mmaping address' is return value of FAPEX_VIDEC_Mmap. The 'Frame_Bank_Size' is got with command FAPEX_IOCCOM_VIDEC_GET_FRAME_BANK_SIZE of FAPEX_VIDEC_Ioctl.

Field Documentation

video decoded frame information flag
The value of flags is the bitwise-inclusive OR of values from the following list.

Parameters:
FAPEX_VIDEC_INFO_NONEno decoded frame information
FAPEX_VIDEC_INFO_DEC_AVAILABLEavailable flag for first video decode frame
FAPEX_VIDEC_INFO_DISP_AVAILABLEavailable flag for first video display frame
FAPEX_VIDEC_INFO_DISP_ENABLEenable flag for video frame information
FAPEX_VIDEC_INFO_DISP_CHANGED_ARaspect ratio changed
FAPEX_VIDEC_INFO_DISP_CHANGED_FRM_FLDframe/field type changed
FAPEX_VIDEC_INFO_DISP_CHANGED_FLD_INVfield inversion changed
FAPEX_VIDEC_INFO_DISP_CHANGED_DEC_SIZEdecoded frame size changed
FAPEX_VIDEC_INFO_STOPPEDstopped video frame decoding

Aspect Ratio of current decoded frame
This value is enable only when

Parameters:
FAPEX_VIDEC_AR_UNKNOWNUnknown aspect ratio.
FAPEX_VIDEC_AR_4_3Aspect ratio is 4:3.
FAPEX_VIDEC_AR_16_9Aspect ratio is 16:9.
FAPEX_VIDEC_AR_14_9Aspect ratio is 14:9.
FAPEX_VIDEC_AR_221_100Aspect ratio is 221:100.
FAPEX_VIDEC_AR_235_100Aspect ratio is 235:100.

This mode parameter is used to define progressive or interlace modes.
1 : progressive mode, 0 : interlace mode

field inversion flag.
0 : top-bottom field, 1 : bottom-top field

Y offset of video frame buffer
This is offset value from the decoded frame buffer top address mapped by FAPEX_VIDEC_Mmap for luminance component of current image data.

C offset of video frame buffer
This is offset value from the decoded frame buffer top address mapped by FAPEX_VIDEC_Mmap for chrominance component of current image data.
