## Detailed Description

A structure to hold information about a data format.

## Constructor & Destructor Documentation

FormatInfo | ( |  | ) |
| inline

Default constructor - used to initialize arrays

FormatInfo | ( | const char * | _name,
|  | int | fsize = `0`,
|  | int | ftime = `10000`,
|  | const char * | _type = `"audio"`,
|  | int | srate = `8000`,
|  | int | nchan = `1`,
|  | bool | convert = `false`
| ) |  |
| inlineexplicit

Normal constructor

## Member Function Documentation

int dataRate | ( |  | ) | const

Get the data rate in bytes/s

Returns
  Data rate or 0 if variable/undefined

int guessSamples | ( | int | len | ) | const

Guess the number of samples in an encoded data block

Parameters

  len | Length of the data block in octets

Returns
  Number of samples or 0 if unknown

## Member Data Documentation

bool converter

If this is a valid candidate for conversion

int frameSize

Frame size in octets/frame, 0 for non-framed formats

Referenced by DataFormat::frameSize().

int frameTime

Frame time in microseconds, 0 for variable

Referenced by DataFormat::frameTime().

const char* name

Standard no-blanks lowercase format name

int numChannels

Number of channels, typically 1

Referenced by DataFormat::numChannels().

int sampleRate

Rate in samples/second (audio) or 1e-6 frames/second (video), 0 for unknown

Referenced by DataFormat::sampleRate().

const char* type

Format type: "audio", "video", "text"
