wan2.7-i2v (image-to-video): передайте первый кадр + prompt, чтобы оживить изображение, и при желании укажите driving_audio, чтобы портрет следовал движениям губ и ритму аудио. Для полного асинхронного потока см. Обзор Wan.- Управление аудио доступно только в
wan2.7-i2v: HappyHorse i2v не поддерживаетdriving_audio, поэтому для синхронизации губ / rap нужно использоватьwan2.7-i2v. input.mediaобязателен, иначе вышестоящий сервис вернетimage-to-video model ... must provide an image. Каждыйurlдля медиа должен быть общедоступной ссылкой https, которую можно получить напрямую через GET.- Запросы на создание отправляйте в

input.prompt | string | ✓ | — | Текстовый prompt |
input.media | array | ✓ | — | См. таблицу медиа ниже |
parameters.resolution | string | 720P | 720P / 1080P | |
parameters.duration | int | 5 | Целое число от 2 до 15 секунд | |
parameters.prompt_extend | bool | true | Умное переписывание, рекомендуется включить | |
parameters.watermark | bool | false | Водяной знак «сгенерировано ИИ» |
Значения media[]
type | Обязательный | Количество | Примечания |

Проверка статуса и скачивание
После того как у вас естьtask_id, выполните следующие три шага, чтобы опрашивать статус и скачать mp4:
- Опросите
GET /v1/tasks/{task_id}(сAuthorization; запросу не нужен заголовокX-DashScope-Async), каждые 5-10 секунд (не чаще чем раз в 3 секунды), покаstatusне станетcompleted. - Значения статуса:
submitted(в очереди) /in_progress(генерация;progress, когда он часто висит на 30%, — это нормально) /completed(успех) /failed(проверьтеerror). - Скачивание: выполните GET для
result_urlпрямо из ответа, без заголовкаAuthorization(это прямая подписанная ссылка OSS — при отправке Auth возвращается 403);result_urlпо умолчанию истекает через 24 часа, поэтому сохраните его как можно скорее.
curl "https://api.apiyi.com/v1/tasks/f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4" \
-H "Authorization: Bearer sk-your-api-key"

}
# result_url is an OSS signed direct link — do NOT send the Authorization header (it returns 403)
curl -L -o out.mp4 "https://dashscope-result-xxx.oss-cn-beijing.aliyuncs.com/xxx.mp4?Expires=...&Signature=..."
TASK_ID="f8ca39a0-6f4b-4ec2-99bf-8b9649d946c4"
