Details

struct GstWavParse

struct GstWavParse;

Opaque data structure.

Property Details

The "ignore-length" property

  "ignore-length"            gboolean              : Read / Write

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.

Default value: FALSE

Since 0.10.36
