signal

AudioEncoder* QtAV::AVTranscoder::audioEncoder

(

)

const

encoder Use this to set encoder properties and options.

Do not call open()/close() manually

Returns

Encoder instance or null if createAudioEncoder failed

void QtAV::AVTranscoder::audioFrameEncoded ( qreal  timestamp )

signal

bool QtAV::AVTranscoder::createAudioEncoder

(

const QString &

name = QLatin1String("FFmpeg")

)

createEncoder Destroy old encoder and create a new one in filter chain.

Filter has the ownership. You shall not manually open it. Transcoder will set the missing parameters open it.

Parameters

name	registered encoder name, for example "FFmpeg"

Returns

false if failed

bool QtAV::AVTranscoder::createVideoEncoder

(

const QString &

name = QLatin1String("FFmpeg")

)

createEncoder Destroy old encoder and create a new one in filter chain.

Filter has the ownership. You shall not manually open it. Transcoder will set the missing parameters open it.

Parameters

signal

qint64 QtAV::AVTranscoder::startTime

(

)

const

startTime Start to encode after startTime().

To decode from a given time, call sourcePlayer()->setPosition()

(

)

const

void QtAV::AVTranscoder::stop ( )

slot

stop Call stop() to encode delayed frames remains in encoder and then stop encoding.

It's called internally when sourcePlayer() is stopped

void QtAV::AVTranscoder::stopped ( )

signal

VideoEncoder* QtAV::AVTranscoder::videoEncoder

(

)

const

encoder Use this to set encoder properties and options.

If frameRate is not set, source frame rate will be set if it's valid, otherwise VideoEncoder::defaultFrameRate() will be used internally Do not call open()/close() manually

Returns

Encoder instance or null if createVideoEncoder failed
