Parameters

const TDesC8 & aMimeType
const TDesC8 & aOptionalData

MimeType()

IMPORT_C const TDesC8 &MimeType()const

Returns 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.

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.

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.

operator==(const CCompressedVideoFormat &)

IMPORT_C TBooloperator==(const CCompressedVideoFormat &aOther)const

Tests whether this CCompressedVideoFormat is identical to aOther or not.

Parameters

const CCompressedVideoFormat & aOther
