Enum MediaSeek Is SeekAccurate, SeekKeyUnit, SeekSnapAfter, SeekSnapBefore, SeekSnapNearest, SeekTrickMode, SeekTrickModeKeyUnit, SeekTrickModeNoAudio

Constant	Description
SeekAccurate	Accurate seeking is requested, this might be considerably slower for some formats.
SeekKeyUnit	Seek to the nearest keyframe. This might be faster but less accurate.
SeekSnapAfter	Go to a location after the requested position. With the SeekKeyUnit flag, it means the keyframe at of after the requested position.
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.
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.
SeekTrickMode	When doing fast forward or fast reverse playback, allow elements to skip frames instead of generating all frames.
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.
SeekTrickModeNoAudio	When doing fast forward or fast reverse playback, request that audio decoder elements skip decoding and output only gap events or silence.
