GI.GstVideo.Structs.VideoTimeCode

fieldCount must be 0 for progressive video and 1 or 2 for interlaced.

A representation of a SMPTE time code.

hours must be positive and less than 24. Will wrap around otherwise. minutes and seconds must be positive and less than 60. frames must be less than or equal to config.fps_n / config.fps_d These values are *NOT* automatically normalized.

addFrames

videoTimeCodeAddFrames

Arguments

:: (HasCallStack, MonadIO m)

=> VideoTimeCode

tc: a valid VideoTimeCode

-> Int64

frames: How many frames to add or subtract

-> m ()

Adds or subtracts frames amount of frames to tc. tc needs to contain valid data, as verified by videoTimeCodeIsValid.

Since: 1.10

addInterval

videoTimeCodeAddInterval

Arguments

:: (HasCallStack, MonadIO m)

=> VideoTimeCode

tc: The VideoTimeCode where the diff should be added. This must contain valid timecode values.

-> VideoTimeCodeInterval

tcInter: The VideoTimeCodeInterval to add to tc. The interval must contain valid values, except that for drop-frame timecode, it may also contain timecodes which would normally be dropped. These are then corrected to the next reasonable timecode.

-> m (Maybe VideoTimeCode)

Returns: A new VideoTimeCode with tcInter added or Nothing if the interval can't be added.

This makes a component-wise addition of tcInter to tc. For example, adding ("01:02:03:04", "00:01:00:00") will return "01:03:03:04". When it comes to drop-frame timecodes, adding ("00:00:00;00", "00:01:00:00") will return "00:01:00;02" because of drop-frame oddities. However, adding ("00:09:00;02", "00:01:00:00") will return "00:10:00;00" because this time we can have an exact minute.

Since: 1.12

clear

videoTimeCodeClear

Arguments

:: (HasCallStack, MonadIO m)

=> VideoTimeCode

tc: a VideoTimeCode

-> m ()

Initializes tc with empty/zero/NULL values and frees any memory it might currently use.
