[−][src]Enum gstreamer::FlowReturn
The result of passing data to a pad.
Note that the custom return values should not be exposed outside of the element scope.
Variants (Non-exhaustive)
Pre-defined custom success code.
Pre-defined custom success code (define your custom success code to this to avoid compiler warnings).
Elements can use values starting from this (and higher) to define custom success codes.
Data passing was ok.
Pad is not linked.
Pad is flushing.
Pad is EOS.
Pad is not negotiated.
Some (fatal) error occurred. Element generating this error should post an error message with more details.
This operation is not supported.
Elements can use values starting from this (and lower) to define custom error codes.
Pre-defined custom error code (define your custom error code to this to avoid compiler warnings).
Pre-defined custom error code.
