Chromecast Custom Receiver JPG loading

Question

Я не могу наложить простой файл JPG или PNG на устройство хромирования. я получаю сообщение об ошибке

[cast.receiver.MediaManager] Load metadata error 

Я даже попытался это с примерами Google, «sample_media_receiver.html» и «web_sender_tool.html», но без успеха.

Видеофайлы, такие как MP4 или даже HLS, работают отлично, но не простое изображение. На самом деле в приемнике по умолчанию изображения работают, но не в пользовательском приемнике.

Я пытался использовать разные значения метаданных и без каких-либо метаданных - ничего не помогает.

Вот лог консоли CHROMECAST (с рабочим MP4 и не работает JPG):

Что не так?

Answer 1

Когда вы говорите «пользовательский приемник», это означает, что вы написали свой собственный ресивер. При этом вы добавили тег <img/> для изображений и связанную с ним логику для использования этого элемента для изображений? Похоже, что нет. Приемники Styled и Default делают это, поэтому вы можете видеть изображения при использовании этих приемников.
