Type | Topic | Plugin | Version | macOS | Windows | Linux | iOS | Targets |
property | AVFoundation | MBS AVFoundation Plugin | 14.0 | ✅ Yes | ❌ No | ❌ No | ✅ Yes | All |
If YES, rendering a frame from the same source buffers and the same composition instruction at two different compositionTime may yield different output frames. If NO, two such compositions will yield the same frame.
The media pipeline may be able to avoid some duplicate processing when this property is set to false.

The dimensions, clean aperture and pixel aspect ratio of the source buffer are matched to the required values automatically.
