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
