Function Documentation

getLastError()

QString getLastError

(

)

Get the last error message.

isDecodableFile()

bool isDecodableFile

(

const QString &

file

)

Check if a file can be decoded using ffmpeg.

readTagsFromFile()

QMap< QString, QVariant > readTagsFromFile

(

const QString &

fileName

)

Tag reader using ffmpeg. Gets artist, title, bpm and length (in milliseconds) and puts them in a map.

Parameters

fileName

The path to the audio file.

Returns

A map with the tags read. If a tag is not found, the key will have a sane default value.

removeBpmFromFile()

bool removeBpmFromFile

(

const QString &

fileName

)

Remove BPM metadata from audio file.

If this is a MP3 file, the TBPM tag of ID3v2 will be removed. Other formats will have the generic "BPM" tag removed.

Parameters

fileName

The path to the audio file.

Returns

true if the BPM metadata was successfully removed, false otherwise.

storeBpmInFile()

bool storeBpmInFile	(	const QString &	fileName,
		const QString &	sBpm )

Store BPM to audio file.

If this is a MP3 file, the BPM will be stored in the TBPM tag of ID3v2. Other formats will have the BPM saved in a generic "BPM" tag. This will return false in those cases as well as for any errors.

Parameters

fileName	The path to the audio file.
sBpm	The BPM value to store.

Returns

true if the BPM was successfully stored, false otherwise.
