Pushes the input buffer filled with data to an audio decoder. The [OH_AVCodecOnNeedInputData](_codec_base.md#oh_avcodeconneedinputdata) callback reports available input buffers and their indexes. After being pushed to the decoder, a buffer is not accessible until the buffer with the same index is reported again through the [OH_AVCodecOnNeedInputData](_codec_base.md#oh_avcodeconneedinputdata) callback. In addition, some decoders require the input of codec-specific data to initialize the decoding process.
