GI.Gst.Structs.BufferPoolAcquireParams

Parameters passed to the bufferPoolAcquireBuffer function to control the allocation of the buffer.

The default implementation ignores the start and stop members but other implementations can use this extra information to decide what buffer to return.

Exported types

newtype BufferPoolAcquireParams

Memory-managed wrapper type.

Constructors

BufferPoolAcquireParams (ManagedPtr BufferPoolAcquireParams)

Instances

WrappedPtr BufferPoolAcquireParams

wrappedPtrCalloc :: IO (Ptr BufferPoolAcquireParams)

wrappedPtrCopy :: BufferPoolAcquireParams -> IO BufferPoolAcquireParams

wrappedPtrFree :: Maybe (GDestroyNotify BufferPoolAcquireParams)

tag ~ AttrSet => Constructible BufferPoolAcquireParams tag

Defined in GI.Gst.Structs.BufferPoolAcquireParams

Methods

new :: MonadIO m => (ManagedPtr BufferPoolAcquireParams -> BufferPoolAcquireParams) -> [AttrOp BufferPoolAcquireParams tag] -> m BufferPoolAcquireParams

newZeroBufferPoolAcquireParams :: MonadIO m => m BufferPoolAcquireParams

Construct a BufferPoolAcquireParams struct initialized to zero.

noBufferPoolAcquireParams :: Maybe BufferPoolAcquireParams

A convenience alias for Nothing :: Maybe BufferPoolAcquireParams.

Properties

flags

additional flags

getBufferPoolAcquireParamsFlags :: MonadIO m => BufferPoolAcquireParams -> m [BufferPoolAcquireFlags]

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

get bufferPoolAcquireParams #flags

setBufferPoolAcquireParamsFlags :: MonadIO m => BufferPoolAcquireParams -> [BufferPoolAcquireFlags] -> m ()

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

set bufferPoolAcquireParams [ #flags := value ]

format

the format of start and stop

getBufferPoolAcquireParamsFormat :: MonadIO m => BufferPoolAcquireParams -> m Format

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

get bufferPoolAcquireParams #format

setBufferPoolAcquireParamsFormat :: MonadIO m => BufferPoolAcquireParams -> Format -> m ()

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

set bufferPoolAcquireParams [ #format := value ]

start

the start position

getBufferPoolAcquireParamsStart :: MonadIO m => BufferPoolAcquireParams -> m Int64

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

get bufferPoolAcquireParams #start

setBufferPoolAcquireParamsStart :: MonadIO m => BufferPoolAcquireParams -> Int64 -> m ()

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

set bufferPoolAcquireParams [ #start := value ]

stop

the stop position

getBufferPoolAcquireParamsStop :: MonadIO m => BufferPoolAcquireParams -> m Int64

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

get bufferPoolAcquireParams #stop

setBufferPoolAcquireParamsStop :: MonadIO m => BufferPoolAcquireParams -> Int64 -> m ()

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

set bufferPoolAcquireParams [ #stop := value ]
