release
```
boolean release()
```
Free up resources used by the codec instance.
Make sure you call this when you're done to free up any opened component instance instead of relying on the garbage collector to do this for you at some point in the future.

configure
```
boolean configure(android.media.MediaFormat format,
                  android.view.Surface surface,
                  android.media.MediaCrypto crypto,
                  int flags)
```
Configures a component.

参数:

format - The format of the input data (decoder) or the desired format of the output data (encoder). Passing null as format is equivalent to passing an an empty mediaformat.

surface - Specify a surface on which to render the output of this decoder. Pass null as surface if the codec does not generate raw video output (e.g. not a video decoder) and/or if you want to configure the codec for ByteBuffer output.

crypto - Specify a crypto object to facilitate secure decryption of the media data. Pass null as crypto for non-secure codecs.

flags - Specify CONFIGURE_FLAG_ENCODE to configure the component as an encoder.

返回:

是否配置成功，如果失败获取configureError

configure

boolean configure(android.media.MediaFormat format,
                  android.view.Surface surface,
                  int flags,
                  android.media.MediaDescrambler descrambler)
```
Configure a component to be used with a descrambler.

参数:

format - The format of the input data (decoder) or the desired format of the output data (encoder). Passing null as format is equivalent to passing an an empty mediaformat.

surface - Specify a surface on which to render the output of this decoder. Pass null as surface if the codec does not generate raw video output (e.g. not a video decoder) and/or if you want to configure the codec for ByteBuffer output.

flags - Specify CONFIGURE_FLAG_ENCODE to configure the component as an encoder.

descrambler - Specify a descrambler object to facilitate secure descrambling of the media data, or null for non-secure codecs.

返回:

是否配置成功，如果失败获取configureError

setOutputSurface
```
boolean setOutputSurface(android.view.Surface surface)
```
Dynamically sets the output surface of a codec.
This can only be used if the codec was configured with an output surface. The new output surface should have a compatible usage type to the original output surface. E.g. codecs may not support switching from a SurfaceTexture (GPU readable) output to ImageReader (software readable) output.

参数:

surface - the output surface to use. It must not be null.

返回:

是否配置成功，如果失败获取configureError

setInputSurface
```
boolean setInputSurface(android.view.Surface surface)
```
Configures the codec (e.g. encoder) to use a persistent input surface in place of input buffers. This may only be called after configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int) and before start(), in lieu of createInputSurface().

参数:

surface - a persistent input surface created by createPersistentInputSurface

返回:

是否配置成功，如果失败获取configureError

createInputSurface
```
android.view.Surface createInputSurface()
```
Requests a Surface to use as the input to an encoder, in place of input buffers. This may only be called after configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int) and before start().
The application is responsible for calling release() on the Surface when done.
The Surface must be rendered with a hardware-accelerated API, such as OpenGL ES. Surface.lockCanvas(android.graphics.Rect) may fail or produce unexpected results.

start
```
boolean start()
```
After successfully configuring the component, call start.
Call start also if the codec is configured in asynchronous mode, and it has just been flushed, to resume requesting input buffers.

返回:

是否配置成功，如果失败获取configureError

stop
```
boolean stop()
```
Finish the decode/encode session, note that the codec instance remains active and ready to be start()ed again. To ensure that it is available to other client call release() and don't just rely on garbage collection to eventually do this for you.

返回:

是否配置成功，如果失败获取configureError

flush
```
boolean flush()
```
Flush both input and output ports of the component.
Upon return, all indices previously returned in calls to dequeueInputBuffer and dequeueOutputBuffer — or obtained via Callback#onInputBufferAvailable onInputBufferAvailable or Callback#onOutputBufferAvailable onOutputBufferAvailable callbacks — become invalid, and all buffers are owned by the codec.
If the codec is configured in asynchronous mode, call start() after flush has returned to resume codec operations. The codec will not request input buffers until this has happened. Note, however, that there may still be outstanding onOutputBufferAvailable callbacks that were not handled prior to calling flush. The indices returned via these callbacks also become invalid upon calling flush and should be discarded.
If the codec is configured in synchronous mode, codec will resume automatically if it is configured with an input surface. Otherwise, it will resume when dequeueInputBuffer is called.

返回:

是否配置成功，如果失败获取configureError

queueInputBuffer
```
boolean queueInputBuffer(int index,
                         int offset,
                         int size,
                         long presentationTimeUs,
                         int flags)
```
After filling a range of the input buffer at the specified index submit it to the component. Once an input buffer is queued to the codec, it MUST NOT be used until it is later retrieved by getInputBuffer(int) in response to a dequeueInputBuffer(long) return value or a Callback#onInputBufferAvailable callback.
Many decoders require the actual compressed data stream to be preceded by "codec specific data", i.e. setup data used to initialize the codec such as PPS/SPS in the case of AVC video or code tables in the case of vorbis audio. The class MediaExtractor provides codec specific data as part of the returned track format in entries named "csd-0", "csd-1" ...
These buffers can be submitted directly after start() or flush() by specifying the flag BUFFER_FLAG_CODEC_CONFIG . However, if you configure the codec with a MediaFormat containing these keys, they will be automatically submitted by MediaCodec directly after start. Therefore, the use of BUFFER_FLAG_CODEC_CONFIG flag is discouraged and is recommended only for advanced users.
To indicate that this is the final piece of input data (or rather that no more input data follows unless the decoder is subsequently flushed) specify the flag BUFFER_FLAG_END_OF_STREAM.
Note: Prior to Build.VERSION_CODES.M, presentationTimeUs was not propagated to the frame timestamp of (rendered) Surface output buffers, and the resulting frame timestamp was undefined. Use releaseOutputBuffer(int, long) to ensure a specific frame timestamp is set. Similarly, since frame timestamps can be used by the destination surface for rendering synchronization, care must be taken to normalize presentationTimeUs so as to not be mistaken for a system time. (See SurfaceView specifics).

参数:

index - The index of a client-owned input buffer previously returned in a call to dequeueInputBuffer(long).

offset - The byte offset into the input buffer at which the data starts.

size - The number of bytes of valid input data.

presentationTimeUs - 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 SurfaceTexture#getTimestamp timestamp for the frame (after conversion to nanoseconds).

flags - A bitmask of flags BUFFER_FLAG_CODEC_CONFIG and BUFFER_FLAG_END_OF_STREAM. While not prohibited, most codecs do not use the BUFFER_FLAG_KEY_FRAME flag for input buffers.

返回:

是否配置成功，如果失败获取configureError

queueSecureInputBuffer
```
boolean queueSecureInputBuffer(int index,
                               int offset,
                               android.media.MediaCodec.CryptoInfo info,
                               long presentationTimeUs,
                               int flags)
```
Similar to queueInputBuffer but submits a buffer that is potentially encrypted. Check out further notes at queueInputBuffer.

参数:

index - The index of a client-owned input buffer previously returned in a call to dequeueInputBuffer(long).

offset - The byte offset into the input buffer at which the data starts.

info - Metadata required to facilitate decryption, the object can be reused immediately after this call returns.

presentationTimeUs - The presentation timestamp in microseconds for this buffer. This is normally the media time at which this buffer should be presented (rendered).

flags - A bitmask of flags BUFFER_FLAG_CODEC_CONFIG and BUFFER_FLAG_END_OF_STREAM. While not prohibited, most codecs do not use the BUFFER_FLAG_KEY_FRAME flag for input buffers.

返回:

是否配置成功，如果失败获取configureError

dequeueInputBuffer
```
int dequeueInputBuffer(long timeoutUs)
```
Returns the index of an input buffer to be filled with valid data or -1 if no such buffer is currently available. This method will return immediately if timeoutUs == 0, wait indefinitely for the availability of an input buffer if timeoutUs < 0 or wait up to "timeoutUs" microseconds if timeoutUs > 0.

参数:

timeoutUs - The timeout in microseconds, a negative timeout indicates "infinite".

dequeueOutputBuffer
```
int dequeueOutputBuffer(android.media.MediaCodec.BufferInfo info,
                        long timeoutUs)
```
Dequeue an output buffer, block at most "timeoutUs" microseconds. Returns the index of an output buffer that has been successfully decoded or one of the INFO_* constants.

参数:

info - Will be filled with buffer meta data.

timeoutUs - The timeout in microseconds, a negative timeout indicates "infinite".

releaseOutputBuffer
```
boolean releaseOutputBuffer(int index,
                            boolean render)
```
If you are done with a buffer, use this call to return the buffer to the codec or to render it on the output surface. If you configured the codec with an output surface, setting render to true will first send the buffer to that output surface. The surface will release the buffer back to the codec once it is no longer used/displayed.
Once an output buffer is released to the codec, it MUST NOT be used until it is later retrieved by getOutputBuffer(int) in response to a dequeueOutputBuffer(android.media.MediaCodec.BufferInfo, long) return value or a Callback#onOutputBufferAvailable callback.

参数:

index - The index of a client-owned output buffer previously returned from a call to dequeueOutputBuffer(android.media.MediaCodec.BufferInfo, long).

render - If a valid surface was specified when configuring the codec, passing true renders this output buffer to the surface.

返回:

是否配置成功，如果失败获取configureError

releaseOutputBuffer

boolean releaseOutputBuffer(int index,
                            long renderTimestampNs)

If you are done with a buffer, use this call to update its surface timestamp and return it to the codec to render it on the output surface. If you have not specified an output surface when configuring this video codec, this call will simply return the buffer to the codec.

The timestamp may have special meaning depending on the destination surface.

SurfaceView specifics

SurfaceView specifics
If you render your buffer on a `SurfaceView`, you can use the timestamp to render the buffer at a specific time (at the VSYNC at or after the buffer timestamp). For this to work, the timestamp needs to be reasonably close to the current `System.nanoTime()`. Currently, this is set as within one (1) second. A few notes: the buffer will not be returned to the codec until the timestamp has passed and the buffer is no longer used by the `Surface`. buffers are processed sequentially, so you may block subsequent buffers to be displayed on the `Surface`. This is important if you want to react to user action, e.g. stop the video or seek. if multiple buffers are sent to the `Surface` to be rendered at the same VSYNC, the last one will be shown, and the other ones will be dropped. if the timestamp is not "reasonably close" to the current system time, the `Surface` will ignore the timestamp, and display the buffer at the earliest feasible time. In this mode it will not drop frames. for best performance and quality, call this method when you are about two VSYNCs' time before the desired render time. For 60Hz displays, this is about 33 msec.

```
android.media.MediaFormat getOutputFormat()
```
Call this after dequeueOutputBuffer signals a format change by returning

getInputFormat
```
android.media.MediaFormat getInputFormat()
```
Call this after configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int) returns successfully to get the input format accepted by the codec. Do this to determine what optional configuration parameters were supported by the codec.

getOutputFormat
```
android.media.MediaFormat getOutputFormat(int index)
```
Returns the output format for a specific output buffer.

参数:

index - The index of a client-owned input buffer previously returned from a call to dequeueInputBuffer(long).

返回:

the format for the output buffer, or null if the index is not a dequeued output buffer.

getInputBuffers
```
java.nio.ByteBuffer[] getInputBuffers()
```
Retrieve the set of input buffers. Call this after start() returns. After calling this method, any ByteBuffers previously returned by an earlier call to this method MUST no longer be used.

Note: As of API 21, dequeued input buffers are automatically cleared.
Do not use this method if using an input surface.

getOutputBuffers
```
java.nio.ByteBuffer[] getOutputBuffers()
```
Retrieve the set of output buffers. Call this after start() returns and whenever dequeueOutputBuffer signals an output buffer change by returning INFO_OUTPUT_BUFFERS_CHANGED . After calling this method, any ByteBuffers previously returned by an earlier call to this method MUST no longer be used.

Note: As of API 21, the position and limit of output buffers that are dequeued will be set to the valid data range.
Do not use this method if using an output surface.

getInputBuffer
```
java.nio.ByteBuffer getInputBuffer(int index)
```
Returns a cleared, writable ByteBuffer object for a dequeued input buffer index to contain the input data.
After calling this method any ByteBuffer or Image object previously returned for the same input index MUST no longer be used.

参数:

index - The index of a client-owned input buffer previously returned from a call to dequeueInputBuffer(long), or received via an onInputBufferAvailable callback.

返回:

the input buffer, or null if the index is not a dequeued input buffer, or if the codec is configured for surface input.

getInputImage
```
android.media.Image getInputImage(int index)
```
Returns a writable Image object for a dequeued input buffer index to contain the raw input video frame.
After calling this method any ByteBuffer or Image object previously returned for the same input index MUST no longer be used.

参数:

index - The index of a client-owned input buffer previously returned from a call to dequeueInputBuffer(long), or received via an onInputBufferAvailable callback.

返回:

the input image, or null if the index is not a dequeued input buffer, or not a ByteBuffer that contains a raw image.

getOutputBuffer
```
java.nio.ByteBuffer getOutputBuffer(int index)
```
Returns a read-only ByteBuffer for a dequeued output buffer index. The position and limit of the returned buffer are set to the valid output data.
After calling this method, any ByteBuffer or Image object previously returned for the same output index MUST no longer be used.

参数:

index - The index of a client-owned output buffer previously returned from a call to dequeueOutputBuffer(android.media.MediaCodec.BufferInfo, long), or received via an onOutputBufferAvailable callback.

返回:

the output buffer, or null if the index is not a dequeued output buffer, or the codec is configured with an output surface.

getOutputImage
```
android.media.Image getOutputImage(int index)
```
Returns a read-only Image object for a dequeued output buffer index that contains the raw video frame.
After calling this method, any ByteBuffer or Image object previously returned for the same output index MUST no longer be used.

参数:

index - The index of a client-owned output buffer previously returned from a call to dequeueOutputBuffer(android.media.MediaCodec.BufferInfo, long), or received via an onOutputBufferAvailable callback.

返回:

the output image, or null if the index is not a dequeued output buffer, not a raw video frame, or if the codec was configured with an output surface.

setVideoScalingMode
```
boolean setVideoScalingMode(int mode)
```
If a surface has been specified in a previous call to configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int) specifies the scaling mode to use. The default is "scale to fit".
The scaling mode may be reset to the default each time an INFO_OUTPUT_BUFFERS_CHANGED event is received from the codec; therefore, the client must call this method after every buffer change event (and before the first output buffer is released for rendering) to ensure consistent scaling mode.
Since the INFO_OUTPUT_BUFFERS_CHANGED event is deprecated, this can also be done after each INFO_OUTPUT_FORMAT_CHANGED event.

返回:

是否配置成功，如果失败获取configureError

getName
```
java.lang.String getName()
```
Get the component name. If the codec was created by createDecoderByType or createEncoderByType, what component is chosen is not known beforehand.

getMetrics
```
android.os.PersistableBundle getMetrics()
```
Return Metrics data about the current codec instance.

返回:

a PersistableBundle containing the set of attributes and values available for the media being handled by this instance of MediaCodec The attributes are descibed in MetricsConstants.
Additional vendor-specific fields may also be present in the return value.

setParameters
```
boolean setParameters(android.os.Bundle params)
```
Communicate additional parameter changes to the component instance. Note: Some of these parameter changes may silently fail to apply.

参数:

params - The bundle of parameters to set.

返回:

是否配置成功，如果失败获取configureError

setCallback
```
boolean setCallback(android.media.MediaCodec.Callback cb,
                    android.os.Handler handler)
```
Sets an asynchronous callback for actionable MediaCodec events.
If the client intends to use the component in asynchronous mode, a valid callback should be provided before configure(android.media.MediaFormat, android.view.Surface, android.media.MediaCrypto, int) is called.
When asynchronous callback is enabled, the client should not call getInputBuffers(), getOutputBuffers(), dequeueInputBuffer(long) or dequeueOutputBuffer(BufferInfo, long).
Also, flush() behaves differently in asynchronous mode. After calling flush, you must call start() to "resume" receiving input buffers, even if an input surface was created.

参数:

cb - The callback that will run. Use null to clear a previously set callback (before configure is called and run in synchronous mode).

handler - Callbacks will happen on the handler's thread. If null, callbacks are done on the default thread (the caller's thread or the main thread.)

返回:

是否配置成功，如果失败获取configureError

setCallback
```
boolean setCallback(android.media.MediaCodec.Callback cb)
```
Sets an asynchronous callback for actionable MediaCodec events on the default looper.
Same as setCallback(Callback, Handler) with handler set to null.

参数:

cb - The callback that will run. Use null to clear a previously set callback (before configure is called and run in synchronous mode).

返回:

是否配置成功，如果失败获取configureError

setOnFrameRenderedListener
```
boolean setOnFrameRenderedListener(android.media.MediaCodec.OnFrameRenderedListener listener,
                                   android.os.Handler handler)
```
Registers a callback to be invoked when an output frame is rendered on the output surface.
This method can be called in any codec state, but will only have an effect in the Executing state for codecs that render buffers to the output surface.
Note: This callback is for informational purposes only: to get precise render timing samples, and can be significantly delayed and batched. Some frames may have been rendered even if there was no callback generated.

参数:

listener - the callback that will be run

handler - the callback will be run on the handler's thread. If null, the callback will be run on the default thread, which is the looper from which the codec was created, or a new thread if there was none.

返回:

是否配置成功，如果失败获取configureError

getCodecInfo
```
android.media.MediaCodecInfo getCodecInfo()
```
Get the codec info. If the codec was created by createDecoderByType or createEncoderByType, what component is chosen is not known beforehand, and thus the caller does not have the MediaCodecInfo.

抛出:

java.lang.IllegalStateException - if in the Released state.
