View Source Membrane.Opus.Parser (Membrane Opus plugin v0.20.1)

Parses a raw incoming Opus stream and adds stream_format information, as well as metadata.

Adds the following metadata:

duration :: non_neg_integer() Number of nanoseconds encoded in this packet

Element options

Passed via struct Membrane.Opus.Parser.t/0

delimitation
```
delimitation_t()
```
Default value: :keep
If input is delimitted? (as indicated by the self_delimiting? field in %Opus) and :undelimit is selected, will remove delimiting.
If input is not delimitted? and :delimit is selected, will add delimiting.
If :keep is selected, will not change delimiting.
Otherwise will act like :keep.
See https://tools.ietf.org/html/rfc6716#appendix-B for details on the self-delimiting Opus format.
input_delimitted?
```
boolean()
```
Default value: false
If you know that the input is self-delimitted? but you're reading from some element that isn't sending the correct structure, you can set this to true to force the Parser to assume the input is self-delimitted? and ignore upstream stream_format information on self-delimitation.
generate_best_effort_timestamps?
```
boolean()
```
Default value: false
If this is set to true parser will try to generate timestamps starting from 0 and increasing them by frame duration, otherwise it will pass pts from input to output, even if it's nil.
