Encoders are used to capture image frames of an HTML <canvas/> and encode them into videos. Each instance of an encoder represents a file artifact. During capture, they provide asynchronous functions for adding frames and saving videos. See DeckAdapter.render for usage.
| Encoder Class | Type | Description |
|---|---|---|
FrameEncoder | Base | The base encoder needs to be implemented with a start, add, and save function. |
PreviewEncoder | Utility | A mock encoder used to preview animations. |
WebMEncoder | Video | Encodes .webm video using Whammy. |
GIFEncoder | Animated Image | Encodes .gif images using gifshot.js. |
StreamEncoder | Video | Encodes .webm rough previews, but drops frames. |
PNGSequenceEncoder | Image Sequence | Encodes video frames as loseless .png contained in a .tar. |
