## Functions

## Types and Values

### struct GstWavParse

    struct GstWavParse;

Opaque data structure.

## Property Details

### The `“ignore-length”` property

      “ignore-length”            gboolean

This selects whether the length found in a data chunk should be ignored. This may be useful for streamed audio where the length is unknown until the end of streaming, and various software/hardware just puts some random value in there and hopes it doesn't break too much.

Flags: Read / Write

Default value: FALSE
