Class TMPEG4VisualGOVHeader

class TMPEG4VisualGOVHeader;

Description

Mpeg4 visual GOV header.

Members

Defined in TMPEG4VisualGOVHeader:
iBrokenLink, iClosedGOV, iTimeCodeHours, iTimeCodeMinutes, iTimeCodeSeconds

TUint iTimeCodeHours;

Description

iTimeCodeHours, iTimeCodeMinutes and iTimeCodeSeconds together specify the modulo part (i.e. the full second units) of the time base for the first object plane (in display order) after the GOV header according to the semantics of the time_code syntax element of MPEG-4 Visual.

TUint iTimeCodeMinutes;

Description

iTimeCodeHours, iTimeCodeMinutes and iTimeCodeSeconds together specify the modulo part (i.e. the full second units) of the time base for the first object plane (in display order) after the GOV header according to the semantics of the time_code syntax element of MPEG-4 Visual.

TUint iTimeCodeSeconds;

Description

iTimeCodeHours, iTimeCodeMinutes and iTimeCodeSeconds together specify the modulo part (i.e. the full second units) of the time base for the first object plane (in display order) after the GOV header according to the semantics of the time_code syntax element of MPEG-4 Visual.

TBool iClosedGOV;

Description

Indicates the nature of the predictions used in the first consecutive B-VOPs (if any) immediately following the first coded I-VOP after the GOV header. iClosedGOV equal to ETrue indicates that there are no such B-VOPs or that these B-VOPs have been encoded using only backward prediction or intra coding. The value of iClosedGOV shall be set equal to the value of closed_gov syntax element of MPEG-4 Visual.

TBool iBrokenLink;

Description

iBrokenLink equal to ETrue indicates that the first consecutive B-VOPs (if any) immediately following the first coded I-VOP following the GOV header may not be correctly decoded because the reference frame which is used for prediction is not available (e.g., due to result of editing in compressed domain). A decoder may use this flag to avoid displaying frames that cannot be correctly decoded. The value of iBrokenLink shall be set equal to the value of broken_link syntax element of MPEG-4 Visual.
