Different values pace result one of these different states with the corresponding effect. In the case of pausing, it keeps the session alive, i.e. it remains connected to video servers and joined in multicast groups. If an exception is raised, the player state is unaffected.

See also:

Parameters:

Name	Type	Description
`pace`	number	The pace at which the position will change, given as a multiplier of normal playback times 1000. Zero will pause the stream. 1000 is normal speed (playing). Values above 1000 will result in fast forward, and below -1000 will result in rewind. This are desired paces, the actual implementation may not set the desired speed, but the different states will change according to this description.

Throws:

ToiSessionViolationException	Raised if the player does not have an active session and will not have one soon (due to a recent call to Open) either.
ToiOperationNotSupportedException	If the player is in a state is which this operation is not supported, an operation not supported exception is raised. This is the case when in ToiMediaPlayerBase.STATE_FAILED, for example. What is supported in which state may in other cases vary depending on which media source is used.
ToiUnavailableException	Raised if the player is temporarily unavailable due to platform resource management.

playFromPosition ( position , pace )

This function moves the playback position of the current stream and resumes playback at the new position with the desired pace. Streams without a well defined notion of beginning and end, like multicast channels, generally do not support this operation, unless timeshift has been enabled. A position value greater than the length of the stream will be clamped.

If this function returns successfully, the player state will change to one of four states: STATE_PLAYING, STATE_PAUSED, STATE_FASTFORWARDING, and STATE_REWINDING. Different values of pace results in the different states. In the case of pausing, it keeps the session alive, i.e. it remains connected to the video server or the joined in multicast group. If an exception is raised, the player state is unaffected.

Parameters:

Name Type Description

position

number

The position, specified as the number of milliseconds from the beginning of the stream, to which the playback position is to be moved. The seekable range of the stream can be obtained by calling the ToiMediaPlayer#getPositionInfo function.

When playing from the timeshift buffer, the constant ToiMediaPlayerBase.POSITION_LIVE can be used to stop buffer playback and start playback of the live stream.

pace

number

The pace at which the position will change, given as a multiplier of normal playback times 1000. Zero will pause the stream. 1000 is normal speed (playing). Values above 1000 will result in fast forward, and below -1000 will result in rewind. This are desired paces, the actual implementation may not set the desired speed, but the different states will change according to this description.

Throws:

ToiSessionViolationException	Raised if the player does not have an active session and will not have one soon (due to a recent call to Open) either .
ToiOperationNotSupportedException	If the player is in a state is which this operation is not supported, an operation not supported exception is raised. This is the case when in ToiMediaPlayerBase.STATE_FAILED, for example. What is supported in which state may in other cases vary depending on which media source is used. The client may investigate this in advance by checking capabilities with ToiMediaPlayer#getCapabilities.
ToiInvalidArgumentException	Raised if the position is negative.
ToiUnavailableException	Raised if the player is temporarily unavailable due to platform resource management.

quickPlay ( url )

This function closes any existing playback session and starts playback in a new session. It is the combination of ToiMediaPlayer#close, ToiMediaPlayer#open and ToiMediaPlayer#play. If there is an ongoing timeshift on the current session, it will be stopped or discarded depending on the current timeshift recording configuration ToiInformationService.CFG_MEDIA_TIMESHIFT_RECORDINGPOLICY. If this function returns successfully, the player state will change to ToiMediaPlayerBase.STATE_CONNECTING. If an exception is raised, the player state is unaffected.

The player will make a second state transition depending on the result of connecting to new media source. If the player successfully connects to the source and starts playback, the player state will change to ToiMediaPlayerBase.STATE_PLAYING. If not, the state will change to ToiMediaPlayerBase.STATE_FAILED. In any respect, the application will be notified of the state transitio with event ToiMediaPlayerStateChangedEvent. In ToiMediaPlayerBase.STATE_FAILED, ToiMediaPlayer#close or ToiMediaPlayer#quickPlay can be called to reset the player or start new playback, respectively.

ToiUnavailableException	Raised if the player is temporarily unavailable due to platform resource management.

quickPlayFromPosition ( url , position )

This function is same as ToiMediaPlayer#quickPlay, except that it starts playback in a new session from a specified position.
