@brief Callback of getting the path and size of the audio data you input.
When you call openWithCustomSource{@link #IMediaPlayer#openWithCustomSource} API to play the in-memory audio data you input, this callback will be triggered and you need to enter the path and size of the audio data.
@param buffer The path of the audio data you input. The size of audio data should be equal to or less than the value of bufferSize. The supported formats are: mp3, aac, m4a, 3gp, wav.
@param bufferSize The size of the audio data, in bytes. If you want to stop audio playing, you can enter a figure less than or equal to zero into bufferSize and then SDK will stop calling this callback.
@return Returns the size of the audio data that are actually read.
@note If calling openWithCustomSource{@link #IMediaPlayer#openWithCustomSource} API failed, please enter 0 into buffer and bufferSize. In this situation, SDK will stop calling this callback.

@brief Seeking the audio data based on the set starting position and offset to help SDK read and analyze data.
When you call openWithCustomSource{@link #IMediaPlayer#openWithCustomSource} API to play the in-memory audio data you input, or when you call setPosition{@link #IMediaPlayer#setPosition} to set the starting position of audio playing, this callback will be trigerred and you need to seek the audio data accorring to the value of offset and whence.
@param offset The offset of the target position relative to the starting position, in bytes. The value can be positive or negative.
@param whence The starting position of the seeking. Refer to MediaPlayerCustomSourceSeekWhence{@link #MediaPlayerCustomSourceSeekWhence} for more details.
@return
If the seeking succeeded, the information on the final adjusted play position after seeking or the size of the audio data will be returned.
If the seeking failed, -1 will be returned.
