## Properties

### ignore-length

    “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
