InputLoopStatus ProcessFormatDetails (const fuchsia::media::FormatDetails & format_details)Processes format details and initializes appropriate internal configurations based
on it.
`codec_params_` should be initialized in this method.
int ProcessInputChunkData (const uint8_t * input_data, size_t input_data_size, uint8_t * output_buffer, size_t output_buffer_size)Processes the data from input data. If processing was successful, returns the number
of output data bytes produced. If an error occurred, it returns -1.
For encoder, this method encodes the input data. For decoder, it decodes the input data.
The method manipulates the output buffer.
size_t InputChunkSize ()The minimum frame size (number of input data bytes that can be processed) is 1 byte.
For convenience and intuition, we enforce the same for `ChunkInputStream::InputBlock`.
size_t MinOutputBufferSize ()Returns the minimum number of bytes required to hold output data that is produced from
processing a single input chunk.
fuchsia::sysmem::BufferCollectionConstraints BufferCollectionConstraints (const CodecPort port)Returns the constraints to use for `CodecAdapter::CoreCodecGetBufferCollectionConstraints`
depending on the port. The fields used are:
- fuchsia::sysmem::BufferCollectionConstraints.min_buffer_count_for_camping
- fuchsia::sysmem::BufferCollectionConstraintsbuffer_memory_constraints.min_size_bytes
- fuchsia::sysmem::BufferCollectionConstraintsbuffer_memory_constraints.max_size_bytes
TimestampExtrapolator CreateTimestampExtrapolator (const fuchsia::media::FormatDetails & format_details)void ResetCodecParams ()Reset codec params. Default behaviour is to reset it to null option.
