QAudioFormat QGstUtils:: audioFormatForBuffer ( int * buffer )

Returns audio format for a buffer. If the buffer doesn't have a valid audio format, an empty QAudioFormat 被返回。

QAudioFormat QGstUtils:: audioFormatForCaps (const int * caps )

Returns audio format for caps. If caps doesn't have a valid audio format, an empty QAudioFormat 被返回。

QSize QGstUtils:: capsCorrectedResolution (const int * caps )

Returns aspect ratio corrected resolution of caps . If caps doesn't have a valid size, an empty QSize 被返回。

int *QGstUtils:: capsForAudioFormat ( const QAudioFormat & )

Builds GstCaps for an audio format. Returns 0 if the audio format is not valid. Caller must unref GstCaps.

QSize QGstUtils:: capsResolution (const int * caps )

Returns resolution of caps . If caps doesn't have a valid size, an empty QSize 被返回。

QMap < QByteArray , QVariant > QGstUtils:: gstTagListToMap (const int * tags )

Convert GstTagList structure to QMap < QByteArray , QVariant >.

Mapping to int, bool, char, string, fractions and date are supported. Fraction values are converted to doubles.
