Public methods

queue

public void queue ()

Finish building a queue request and queue the buffers with tunings.

setEncryptedLinearBlock

public MediaCodec.QueueRequest setEncryptedLinearBlock (MediaCodec.LinearBlock block, 
                int offset, 
                int size, 
                MediaCodec.CryptoInfo cryptoInfo)

Set an encrypted linear block to this queue request. Exactly one buffer must be set for a queue request before calling queue(). It is possible to use the same LinearBlock object for multiple queue requests. The behavior is undefined if the range of the buffer overlaps for multiple requests, or the application writes into the region being processed by the codec.

Parameters
`block`	`MediaCodec.LinearBlock`: The linear block object. This value cannot be `null`.
`offset`	`int`: The byte offset into the input buffer at which the data starts.
`size`	`int`: The number of bytes of valid input data.
`cryptoInfo`	`MediaCodec.CryptoInfo`: Metadata describing the structure of the encrypted input sample. This value cannot be `null`.

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

Throws
`IllegalStateException`	if a buffer is already set

setFloatParameter

public MediaCodec.QueueRequest setFloatParameter (String key, 
                float value)

Add a float parameter. See MediaFormat for an exhaustive list of supported keys with values of type float, that can also be set with MediaFormat.setFloat. If there was MediaCodec.setParameters call with the same key which is not processed by the codec yet, the value set from this method will override the unprocessed value.

Parameters
`key`	`String`: This value cannot be `null`.
`value`	`float`

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

setIntegerParameter

public MediaCodec.QueueRequest setIntegerParameter (String key, 
                int value)

Add an integer parameter. See MediaFormat for an exhaustive list of supported keys with values of type int, that can also be set with MediaFormat.setInteger. If there was MediaCodec.setParameters call with the same key which is not processed by the codec yet, the value set from this method will override the unprocessed value.

Parameters
`key`	`String`: This value cannot be `null`.
`value`	`int`

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

setLinearBlock

public MediaCodec.QueueRequest setLinearBlock (MediaCodec.LinearBlock block, 
                int offset, 
                int size)

Set a linear block to this queue request. Exactly one buffer must be set for a queue request before calling queue(). It is possible to use the same LinearBlock object for multiple queue requests. The behavior is undefined if the range of the buffer overlaps for multiple requests, or the application writes into the region being processed by the codec.

Parameters
`block`	`MediaCodec.LinearBlock`: The linear block object. This value cannot be `null`.
`offset`	`int`: The byte offset into the input buffer at which the data starts.
`size`	`int`: The number of bytes of valid input data.

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

Throws
`IllegalStateException`	if a buffer is already set

setLongParameter

public MediaCodec.QueueRequest setLongParameter (String key, 
                long value)

Add a long parameter. See MediaFormat for an exhaustive list of supported keys with values of type long, that can also be set with MediaFormat.setLong. If there was MediaCodec.setParameters call with the same key which is not processed by the codec yet, the value set from this method will override the unprocessed value.

Parameters
`key`	`String`: This value cannot be `null`.
`value`	`long`

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

setMultiFrameEncryptedLinearBlock

public MediaCodec.QueueRequest setMultiFrameEncryptedLinearBlock (MediaCodec.LinearBlock block, 
                ArrayDeque<MediaCodec.BufferInfo> bufferInfos, 
                ArrayDeque<MediaCodec.CryptoInfo> cryptoInfos)

Set an encrypted linear block to this queue request. Exactly one buffer must be set for a queue request before calling queue(). The block can contain multiple access units and if present should be laid out contiguously and without gaps.

Parameters
`block`	`MediaCodec.LinearBlock`: The linear block object. This value cannot be `null`.
`bufferInfos`	`ArrayDeque`: ArrayDeque of `MediaCodec.BufferInfo` that describes the contents in the buffer. The ArrayDeque and the BufferInfo objects provided can be recycled by the caller for re-use. This value cannot be `null`.
`cryptoInfos`	`ArrayDeque`: ArrayDeque of `MediaCodec.CryptoInfo` that describes the structure of the encrypted input samples. The ArrayDeque and the BufferInfo objects provided can be recycled by the caller for re-use. This value cannot be `null`.

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

Throws
`IllegalArgumentException`	upon if bufferInfos is empty, contains null, or if the access units are not contiguous.
`IllegalStateException`	if a buffer is already set

setMultiFrameLinearBlock

public MediaCodec.QueueRequest setMultiFrameLinearBlock (MediaCodec.LinearBlock block, 
                ArrayDeque<MediaCodec.BufferInfo> infos)

Set a linear block that contain multiple non-encrypted access unit to this queue request. Exactly one buffer must be set for a queue request before calling queue(). Multiple access units if present must be laid out contiguously and without gaps and in order. An IllegalArgumentException will be thrown during queue() if access units are not laid out contiguously.

Parameters
`block`	`MediaCodec.LinearBlock`: The linear block object. This value cannot be `null`.
`infos`	`ArrayDeque`: Represents `MediaCodec.BufferInfo` objects to mark individual access-unit boundaries and the timestamps associated with it. This value cannot be `null`.

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

Throws
`IllegalStateException`	if a buffer is already set

setPresentationTimeUs

public MediaCodec.QueueRequest setPresentationTimeUs (long presentationTimeUs)

Set timestamp to this queue request.

Parameters
`presentationTimeUs`	`long`: The presentation timestamp in microseconds for this buffer. This is normally the media time at which this buffer should be presented (rendered). When using an output surface, this will be propagated as the `timestamp` for the frame (after conversion to nanoseconds).

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.

setStringParameter

public MediaCodec.QueueRequest setStringParameter (String key, 
                String value)

Add a string parameter. See MediaFormat for an exhaustive list of supported keys with values of type string, that can also be set with MediaFormat.setString. If there was MediaCodec.setParameters call with the same key which is not processed by the codec yet, the value set from this method will override the unprocessed value.

Parameters
`key`	`String`: This value cannot be `null`.
`value`	`String`: This value cannot be `null`.

Returns
`MediaCodec.QueueRequest`	this object. This value cannot be `null`.
