# SetAvailableStreamFormats

Sets the available descriptions for the stream.

## Declaration

```occ
kern_return_t SetAvailableStreamFormats(const IOUserVideoStreamBasicDescription *in_formats, uint32_t in_num_formats);
```

## Parameters

- `in_formats`: Pointer to a buffer of descriptions, with a size corresponding to in_num_formats.
- `in_num_formats`: The number of formats in the in_formats buffer.

## Discussion

Discussion Changing the available formats will send a notification to the host to update the object state if successful. The object’s work queue synchronizes access to the stream formats.
