Method Detail

getStreamHandle

public long getStreamHandle()

Description copied from interface: KinesisVideoProducerStream

Returns the underlying native stream handle

Specified by:

getStreamHandle in interface KinesisVideoProducerStream

Returns:

getStreamInfo

public StreamInfo getStreamInfo()

Specified by:

                       throws ProducerException

Description copied from interface: StreamCallbacks

Reports an error for the stream. The client should terminate the connection as the inlet host would have/has already terminated the connection.

Specified by:

streamErrorReport in interface StreamCallbacks

Parameters:

uploadHandle - The client stream upload handle.

fragmentTimecode - Fragment time code of the errored fragment.

getDataStream

@Nonnull
public InputStream getDataStream(long uploadHandle)

Description copied from interface: KinesisVideoProducerStream

Returns the input stream to retrieve the data from.
