MediaCodec.dequeueOutputBuffer возвращает INFO_TRY_AGAIN_LATER в Google Pixel, но не в Samsung Galaxy ⇐ Android

[Anonymous]

Я пытаюсь преобразовать некоторые растровые изображения в видео и закодировать их с помощью этой библиотеки https://github.com/israel-fl/bitmap2video
В FrameBuilder.kt он кодирует задано в AVC/H264.
Однако dequeueOutputBuffer в конце потока вернет -1/INFO_TRY_AGAIN_LATER на моем Google Pixel Pixel 6 Pro, но он отлично работает на Samsung С21/С22. Почему?
