Operator RtpDecode
The RtpDecode Operator converts an input blob with 8 bit mylaw encoded PCM samples into uncompressed 16 bit samples. The output stream attribute with the 16 bit samples must be of type blob and the 16 bit samples are stored in little endian signed integer format.
Summary
- Ports
- This operator has 1 input port and 1 output port.
- Windowing
- This operator does not accept any windowing configurations.
- Parameters
- This operator supports 1 parameter.
Required: payload
- Metrics
- This operator does not report any metrics.
Properties
- Implementation
- C++
- Threading
- Always - Operator always provides a single threaded execution context.
- Ports (0)
-
The input port with an blob attribute containing the PCM samples.
- Properties
-
- Optional: false
- ControlPort: false
- TupleMutationAllowed: false
- WindowingMode: NonWindowed
- WindowPunctuationInputMode: Oblivious
- Assignments
- This operator allows any SPL expression of the correct type to be assigned to output attributes.
- Output Functions
-
- DefaultFunctions
-
- <any T> T AsIs(T)
-
The default function for output attributes. By default, this function assigns the output attribute to the value of the input attribute with the same name.
- uint64 getNumberOfSamples()
-
Return the number of converted PCM samples in the current tuple.
- blob getPcmPayload()
-
Return the converted PCM payload (uncompressed 16 bit little endian integer samples).
- Ports (0)
-
The output port with an blob attribute containing the converted PCM samples. The other attributes are auto assigned from input port to output port.
- Properties
-
- Optional: false
- TupleMutationAllowed: true
- WindowPunctuationOutputMode: Preserving
Required: payload
- payload
-
The input stream attribute with the 8 bit mulaw encoded PCM samples to convert.
