TV standards

typedef enum {

TVS_PAL,

TVS_NTSC,

TVS_MAX, //for array sizing

} S819_TVSTANDARD;

Interlacing

typedef enum {

MODE_INTERLACE = 0,

MODE_PROGRESSIVE,

MODE_MAX, //for array sizing

} S819_INTERLACE;

Currently the only supported value is MODE_INTERLACE.

Bitrate control mode

typedef enum {

BITRATE_H264_NO_RC, //No rate control

BITRATE_H264_CBR, //constant bitrate

BITRATE_H264_VBR, //variable bitrate

BITRATE_MAX, //for array sizing only

} S819_BR_CTRL;

BITRATE_H264_NO_RC – no bitrate control. Actual bitrate depends on video contents.

BITRATE_H264_CBR – constant bitrate. Encoder makes best effort to keep bitrate constant re-

gardless of video contents.

BITRATE_H264_VBR – variable bitrate. Output bitrate varies, but does not exceed the set value.

Capture mode

typedef struct {

S819_TVSTANDARD tvs;

int bright;

int contrast;

int saturation;
