 ### Backpressure
 
-Media sources are the means by which backpressure is propagated from the output pipeline into your application logic. The `Output` may want to apply backpressure if the encoders or the [StreamTarget](./writing-overview/#streamtarget)'s writable can't keep up.

 Backpressure is communicated by media sources via promises. All media sources with an `add` method return a promise:

 - `fullCodecString`: Allows you to optionally specify the full codec string used by the audio encoder, as specified in the [WebCodecs Codec Registry](https://www.w3.org/TR/webcodecs-codec-registry/). For example, you may set it to `'mp4a.40.2'` when using AAC. Keep in mind that the codec string must still match the codec specified in `codec`. If you don't set this field, a codec string will be generated automatically.
 - `onEncodedPacket`: Called for each successfully encoded packet. Useful for determining encoding progress.
