Как можно считать байт-строчку в cv2.VideoCapture? Я попробовал вот так:
cap = cv2.VideoCapture(io.BytesIO(decoded_vid)) # decoded_vid - bytes
При этом я получаю TypeError:
TypeError: Argument 'index' is required to be an integer
Это, кажется, весьма популярный юзкейс, но я не смог найти примеров подробной работы. Еще не совсем понятно, почему он ожидает аргумент intом - даже в официальной доке есть примеры, где аргументом передается строка с путем к файлу.
Полный трейсбек:
