Functions
| Function | Description |
|---|---|
Returns the stream keys for ancillary streams in a media context |
|
Filters a context to only the ancillary streams within it |
|
Returns the stream keys for audio streams in a media context |
|
Filters a context to only the audio streams within it |
|
Generate encryption parameters from from an encryption KeyID and Key, in the form KEYID:KEY, both 16byte hexadecimal |
|
Returns the stream keys for playlist streams in a media context |
|
Filters a context to only the playlist streams within it |
|
Validation function to require at least one audio and at least one video stream. Often the default validation will happen to ensure this, as audio and video are subscribed from separate media nodes, but when one media node will produce both audio and video, default validation cannot know that both are required. |
|
Validation function to require exactly N audio and exactly M video streams. Often the default validation will happen to ensure this, as audio and video are subscribed from separate media nodes, but when one media node will produce both audio and video, default validation cannot know that both are required. |

There are three possible modes: - "abr": encode in average bitrate mode, specified in kilobits/sec (note, 1 kilobit is 1000 bits). You can make use of the vbv settings to control the bounds on how much the actual bitrate can fluctuate within the bounds of the average - "cqp": encode in constant quantizer mode. In general, crf will give better results, although cqp can be faster to encode - "crf": encode in constant rate factor mode. This will give a constant 'quality' to the encode, but with a variable bitrate |

Determines what to do with an incoming context - true/accept: Allow the incoming context through, and any subsequent/queued data that belongs to it - false/deny: Deny the incoming context, if no context has been accepted, then queue data until one is - accept_and_terminate: Allow the incoming context, then deny further data, flush and shut down the node this is useful for cleanly terminating outputs when the context is empty - deny_and_queue: Deny the incoming context, and revert to the original queueing behaviour as if no context has been accepted this is useful when switching from one full context to another, avoiding any "in-between" - deny_and_drop: Deny the incoming context, drop any currently queued data, and drop any further data that might be received this is useful if you have a lot of setup on start-up and would prefer not to queue data while waiting for that to take place |
