Properties

afd

VideoAFDValue AFD value

getVideoAFDMetaAfd :: MonadIO m => VideoAFDMeta -> m VideoAFDValue

Get the value of the “afd” field. When overloading is enabled, this is equivalent to

get videoAFDMeta #afd

setVideoAFDMetaAfd :: MonadIO m => VideoAFDMeta -> VideoAFDValue -> m ()

Set the value of the “afd” field. When overloading is enabled, this is equivalent to

set videoAFDMeta [ #afd := value ]

field

0 for progressive or field 1 and 1 for field 2

getVideoAFDMetaField :: MonadIO m => VideoAFDMeta -> m Word8

Get the value of the “field” field. When overloading is enabled, this is equivalent to

get videoAFDMeta #field

setVideoAFDMetaField :: MonadIO m => VideoAFDMeta -> Word8 -> m ()

Set the value of the “field” field. When overloading is enabled, this is equivalent to

set videoAFDMeta [ #field := value ]

meta

parent Meta

getVideoAFDMetaMeta :: MonadIO m => VideoAFDMeta -> m Meta

Get the value of the “meta” field. When overloading is enabled, this is equivalent to

get videoAFDMeta #meta

spec

VideoAFDSpec that applies to afd

getVideoAFDMetaSpec :: MonadIO m => VideoAFDMeta -> m VideoAFDSpec

Get the value of the “spec” field. When overloading is enabled, this is equivalent to

get videoAFDMeta #spec

setVideoAFDMetaSpec :: MonadIO m => VideoAFDMeta -> VideoAFDSpec -> m ()

Set the value of the “spec” field. When overloading is enabled, this is equivalent to

set videoAFDMeta [ #spec := value ]
