Public methods
queue
public void queue ()
Finish building a queue request and queue the buffers with tunings.
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. |
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 |
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 |
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. |
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 |
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). |
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. |
