Properties
AvailableFrames
获取当前可用的帧数。
public override int AvailableFrames { get; }
Property Value
CanRead
When overridden in a derived class, gets a value indicating whether the current stream supports reading.
public override bool CanRead { get; }
Property Value
CanSeek
When overridden in a derived class, gets a value indicating whether the current stream supports seeking.
public override bool CanSeek { get; }
Property Value
CanWrite
When overridden in a derived class, gets a value indicating whether the current stream supports writing.
public override bool CanWrite { get; }
Property Value
Methods
Dispose(bool)
Releases the unmanaged resources used by the Stream and optionally releases the managed resources.
protected override void Dispose(bool disposing)
Parameters
disposingbooltrue to release both managed and unmanaged resources; false to release only unmanaged resources.
ReadAsync(byte[], int, int, CancellationToken)
Asynchronously reads a sequence of bytes from the current stream, advances the position within the stream by the number of bytes read, and monitors cancellation requests.
public override Task<int> ReadAsync(byte[] buffer, int offset, int count, CancellationToken cancellationToken)
Parameters
bufferbyte[]The buffer to write the data into.
offsetintThe byte offset in
bufferat which to begin writing data from the stream.countintThe maximum number of bytes to read.
cancellationTokenCancellationTokenThe token to monitor for cancellation requests. The default value is None.
Returns
- Task<int>
A task that represents the asynchronous read operation. The value of the
TResultparameter contains the total number of bytes read into the buffer. The result value can be less than the number of bytes requested if the number of bytes currently available is less than the requested number, or it can be 0 (zero) ifcountis 0 or if the end of the stream has been reached.
Exceptions
- ArgumentNullException
bufferis null.- ArgumentOutOfRangeException
offsetorcountis negative.- ArgumentException
The sum of
offsetandcountis larger than the buffer length.- NotSupportedException
The stream does not support reading.
- ObjectDisposedException
The stream has been disposed.
- InvalidOperationException
The stream is currently in use by a previous read operation.
- OperationCanceledException
The cancellation token was canceled. This exception is stored into the returned task.
ReadFrameAsync(CancellationToken)
读取一个 RTP 帧。
public override Task<RtpFrame> ReadFrameAsync(CancellationToken cancellationToken)
Parameters
cancellationTokenCancellationToken用于取消任务的取消令牌。
Returns
TryReadFrame(CancellationToken, out RtpFrame)
尝试读取一个 RTP 帧。
public override bool TryReadFrame(CancellationToken cancellationToken, out RtpFrame frame)
Parameters
cancellationTokenCancellationToken用于取消任务的取消令牌。
frameRtpFrame如果成功读取到 RTP 帧,则为读取到的 RTP 帧;否则为 default。
Returns
- bool
是否成功读取到 RTP 帧。
WriteAsync(byte[], int, int, CancellationToken)
Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests.
public override Task WriteAsync(byte[] buffer, int offset, int count, CancellationToken cancellationToken)
Parameters
bufferbyte[]The buffer to write data from.
offsetintThe zero-based byte offset in
bufferfrom which to begin copying bytes to the stream.countintThe maximum number of bytes to write.
cancellationTokenCancellationTokenThe token to monitor for cancellation requests. The default value is None.
Returns
- Task
A task that represents the asynchronous write operation.
Exceptions
- ArgumentNullException
bufferis null.- ArgumentOutOfRangeException
offsetorcountis negative.- ArgumentException
The sum of
offsetandcountis larger than the buffer length.- NotSupportedException
The stream does not support writing.
- ObjectDisposedException
The stream has been disposed.
- InvalidOperationException
The stream is currently in use by a previous write operation.
- OperationCanceledException
The cancellation token was canceled. This exception is stored into the returned task.
WriteHeader(ushort, uint, bool)
向流中写入一个头部信息。
public override void WriteHeader(ushort seq, uint timestamp, bool missed)
Parameters
Exceptions
- InvalidOperationException
该流不接收头部信息。
