Syntax

public class AVIOContext : IDisposable, IAVPointer<_AVIOContext>

Remarks

An AVIOContext provides buffered input/output operations for media data. It can represent file-based I/O, network streams, memory buffers, or custom user-defined data sources. Instances own the underlying unmanaged context and release it when disposed.

Properties

EOF

Gets a value indicating whether the end of the file (EOF) has been reached.

Declaration

public bool EOF { get; }

Property Value

Type	Description
bool

ErrorCode

Gets the error code associated with the AVIOContext. If no error occurred, this will be >=0.

Declaration

public AVResult32 ErrorCode { get; }

Property Value

Type	Description
AVResult32

Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Declaration

public void Dispose()

Dispose(bool)

Releases the unmanaged resources used by the AVIOContext and optionally releases the managed resources.

Declaration

protected virtual void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing	True to release both managed and unmanaged resources; false to release only unmanaged resources.

~AVIOContext()

Finalizer that releases unmanaged resources before the object is reclaimed by garbage collection.

Declaration

protected ~AVIOContext()

Flush()

Flushes any buffered output data to the underlying destination.

Declaration

public virtual void Flush()

Remarks

This method has an effect only for writable I/O contexts. For read-only contexts, calling this method typically has no effect.

SetContext(_AVIOContext**)

Replaces the underlying unmanaged FFmpeg.AutoGen._AVIOContext.

Declaration

protected void SetContext(_AVIOContext** context)

Parameters

Type	Name	Description
_AVIOContext**	context	A pointer to the new unmanaged context.

Remarks

If this instance already owns a different context, the previous context is released before the new one is assigned. This method is intended for derived classes that create custom AVIO contexts.
