Protected Methods

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

void ResetCodecParams ()

Reset codec params. Default behaviour is to reset it to null option.
