| 47 | * of invalid stream configurations include: |

| 49 | * - Not including any OUTPUT streams |
| 50 | * - Including streams with unsupported formats, or an unsupported |

| 53 | * - Unsupported rotation configuration |
| 54 | * - Stream sizes/formats don't satisfy the |
| 55 | * camera3_stream_configuration_t->operation_mode requirements |
| 56 | * for non-NORMAL mode, or the requested operation_mode is not |
| 57 | * supported by the HAL. |
| 58 | * - Unsupported usage flag |
| 59 | * The camera service cannot filter out all possible illegal stream |
| 60 | * configurations, since some devices may support more simultaneous |
| 61 | * streams or larger stream resolutions than the minimum required |
| 62 | * for a given camera device hardware level. The HAL must return an |
| 63 | * ILLEGAL_ARGUMENT for any unsupported stream set, and then be |
| 64 | * ready to accept a future valid stream configuration in a later |
| 65 | * configureStreams call. |
