fast_start
```
boolean()
```
Default value: false
Generates a container more suitable for streaming by allowing media players to start playback as soon as they start to receive its media data.
When set to true, the container metadata (moov atom) will be placed before media data (mdat atom). The equivalent of FFmpeg's -movflags faststart option. [IMPORTANT] Due to the structure of MPEG-4 containers, the muxer with fast_start: true has to be used along with Membrane.File.Sink or any other sink that can handle Membrane.File.SeekEvent, since that event is used to insert moov box at the beginning of the file.
chunk_duration
```
Time.t()
```
Default value: 1000000000
Expected duration of each chunk in the resulting MP4 container.
Once the total duration of samples received on one of the input pads exceeds that threshold, a chunk containing these samples is flushed. Interleaving chunks belonging to different tracks may have positive impact on performance of media players.
