public void QueueInputBuffers (int index, Java.Util.ArrayDeque bufferInfos);[<Android.Runtime.Register("queueInputBuffers", "(ILjava/util/ArrayDeque;)V", "", ApiSince=35)>]
member this.QueueInputBuffers : int * Java.Util.ArrayDeque -> unitParameters
- index
- Int32
The index of a client-owned input buffer previously returned
in a call to #dequeueInputBuffer.
- 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.

Remarks
Submit multiple access units to the codec along with multiple MediaCodec.BufferInfo describing the contents of the buffer. This method is supported only in asynchronous mode. While this method can be used for all codecs, it is meant for buffer batching, which is only supported by codecs that advertise FEATURE_MultipleFrames. Other codecs will not output large output buffers via onOutputBuffersAvailable, and instead will output single-access-unit output via onOutputBufferAvailable.
Output buffer size can be configured using the following MediaFormat keys. MediaFormat#KEY_BUFFER_BATCH_MAX_OUTPUT_SIZE and MediaFormat#KEY_BUFFER_BATCH_THRESHOLD_OUTPUT_SIZE. Details for each access unit present in the buffer should be described using MediaCodec.BufferInfo. Access units must be laid out contiguously (without any gaps) and in order. Multiple access units in the output if present, will be available in Callback#onOutputBuffersAvailable or Callback#onOutputBufferAvailable in case of single-access-unit output or when output does not contain any buffers, such as flags.
All other details for populating MediaCodec.BufferInfo is the same as described in #queueInputBuffer.
