CCompressedVideoFormat Class Reference

class CCompressedVideoFormat : public CBase

Defines a compressed video format. The format is identified by its MIME type, which may include parameters that describe the used format profile and level. The MIME type used for H.263 is video/H263-2000, specified in TS 26.234, and the type for MPEG-4 is video/MP4V-ES, specified in RFC 3016.

Parameters

const TDesC8 & aMimeType
const TDesC8 & aOptionalData

MimeType()

IMPORT_C const TDesC8 &MimeType()const

Returns the video codec MIME type.

"Reference to a descriptor that contains the video codec MIME type."

NewL(const TDesC8 &, const TDesC8 &)

IMPORT_C CCompressedVideoFormat *NewL(const TDesC8 &aMimeType,
const TDesC8 &aOptionalData =  KNullDesC8
)[static]

Static factory function for creating new CCompressedVideoFormat objects.

"Pointer to a fully constructed CCompressedVideoFormat object."

leave

"This method may leave with one of the system-wide error codes."

Parameters

const TDesC8 & aMimeType"Video codec MIME type, including optional parameters for profile, level and version information. The CCompressedVideoFormat object creates and owns a copy of this buffer and takes care of deallocation."
const TDesC8 & aOptionalData =  KNullDesC8 "Reference to a descriptor that contains optional codec-specific data. Set to KNullDesC8 if not used. [The format of the data is codec-specific, typically a package buffer containing a data structure may be used. The pointer lifetime and validity requirements are specified with each method that uses this structure."

NewL(const CCompressedVideoFormat &)

IMPORT_C CCompressedVideoFormat *NewL(const CCompressedVideoFormat &aFormat)[static]

Static factory function for creating a copy of an existing CCompressedVideoFormat object.

Pointer to a fully constructed CCompressedVideoFormat object.

leave

This method may leave with one of the system-wide error codes.

Parameters

const CCompressedVideoFormat & aFormat"The CCompressedVideoFormat object to copy."

OptionalData()

IMPORT_C const TDesC8 &OptionalData()const

Returns the optional data.

"Reference to a descriptor that contains optional codec-specific data. Zero length if not used. The format of the data is codec-specific, typically a package buffer containing a data structure may be used."

operator==(const CCompressedVideoFormat &)

IMPORT_C TBooloperator==(const CCompressedVideoFormat &aOther)const

Tests whether this CCompressedVideoFormat is identical to aOther or not. "ETrue if the two objects are identical, EFalse if not."

Parameters

const CCompressedVideoFormat & aOther
