Types ¶
type PCMLocalTrack ¶
type PCMLocalTrack struct {
*webrtc.TrackLocalStaticSample
// contains filtered or unexported fields
}
func NewPCMLocalTrack ¶
func NewPCMLocalTrack(sourceSampleRate int, sourceChannels int, logger protoLogger.Logger, opts ...PCMLocalTrackOption) (*PCMLocalTrack, error)
NewPCMLocalTrack creates a wrapper around a webrtc.TrackLocalStaticSample that accepts PCM16 samples via the WriteSample method, encodes them to opus, and writes them to the track. PCMLocalTrack can directly be used as a local track to publish to a room. The sourceSampleRate and sourceChannels are the sample rate and channels of the source audio. It also provides an option to write silence when no data is available, which is disabled by default. Stereo tracks are not supported, they may result in unpleasant audio.
func (*PCMLocalTrack) ClearQueue ¶ added in v2.7.1
func (t *PCMLocalTrack) ClearQueue()
func (*PCMLocalTrack) Close ¶
func (t *PCMLocalTrack) Close()
func (*PCMLocalTrack) WaitForPlayout ¶ added in v2.7.1
func (t *PCMLocalTrack) WaitForPlayout()
func (*PCMLocalTrack) WriteSample ¶
func (t *PCMLocalTrack) WriteSample(sample media.PCM16Sample) error
type PCMLocalTrackOption ¶
type PCMLocalTrackOption func(*PCMLocalTrackParams)
func WithWriteSilenceOnNoData ¶
func WithWriteSilenceOnNoData(writeSilenceOnNoData bool) PCMLocalTrackOption
type PCMLocalTrackParams ¶
type PCMLocalTrackParams struct {
WriteSilenceOnNoData bool
}
type PCMRemoteTrack ¶
type PCMRemoteTrack struct {
// contains filtered or unexported fields
}
func NewPCMRemoteTrack ¶
func NewPCMRemoteTrack(track *webrtc.TrackRemote, writer PCMRemoteTrackWriter, opts ...PCMRemoteTrackOption) (*PCMRemoteTrack, error)
PCMRemoteTrack takes a remote track (currently only opus is supported) and a WriterCloser interface that writes implements a WriteSample method to write PCM16 samples, where the user desires. The PCMRemoteTrack will read RTP packets from the remote track, decode them to PCM16 samples, and write them to the writer. Audio is resampled to targetSampleRate and upmixed/downmixed to targetChannels. It also provides an option to handle jitter, which is enabled by default. Stereo remote tracks are currently not supported, and are known to have a lot of unpleasant noise.
func (*PCMRemoteTrack) Close ¶
func (t *PCMRemoteTrack) Close()
type PCMRemoteTrackOption ¶
type PCMRemoteTrackOption func(*PCMRemoteTrackParams)
func WithHandleJitter ¶
func WithHandleJitter(handleJitter bool) PCMRemoteTrackOption
func WithTargetChannels ¶
func WithTargetChannels(targetChannels int) PCMRemoteTrackOption
func WithTargetSampleRate ¶
func WithTargetSampleRate(targetSampleRate int) PCMRemoteTrackOption
type PCMRemoteTrackParams ¶
type PCMRemoteTrackWriter ¶
type PCMRemoteTrackWriter interface {
WriteSample(sample media.PCM16Sample) error
Close() error
