MediaPipeline.Seek (gb.media)
Sub Seek ( Position As Float [ , Flags As Integer ] )
Move the stream to a specific position, following the constraints defined by the specified flags.
-
Position: the stream position in seconds.
-
Flags: the seeking options.
The
Flags are a logical combination of the following options:
|
Media.SeekAccurate
|
Accurate position is requested, this might be considerably slower for some formats.
|
|
Media.SeekKeyUnit
|
Seek to the nearest keyframe. This might be faster but less accurate.
|
|
Media.SeekTrickMode
|
When doing fast forward or fast reverse playback, allow elements to skip frames instead of generating all frames.
|
|
Media.SeekSnapBefore
|
Go to a location before the requested position. With the SeekKeyUnit flag, it means the keyframe at or before the requested position the one at or before the seek target.
|
|
Media.SeekSnapAfter
|
Go to a location after the requested position. With the SeekKeyUnit flag, it means the keyframe at of after the requested position.
|
|
Media.SeekSnapNearest
|
Go to a position near the requested position. With the SeekKeyUnit flag, it means the keyframe closest to the requested position. If both keyframes are at an equal distance, behaves like SeekSnapBefore.
|
|
Media.SeekTrickModeKeyUnit
|
When doing fast forward or fast reverse playback, request that elements only decode keyframes and skip all other content, for formats that have keyframes.
|
|
Media.SeekTrickModeNoAudio
|
When doing fast forward or fast reverse playback, request that audio decoder elements skip decoding and output only gap events or silence.
