При попытке запустить конвертацию видео или запись на рабочем столе с помощью ffmpeg я получаю это предупреждение желтым цветом: unknown side data type 10 (24 bytes) . Использование ffmpeg в Arch Linux x86_64 скомпилировано из репозитория git (версия git).
Вывод простого преобразования видео:
$ ffmpeg -i video1.avi video2.mp4

Похоже, это не конкретное предупреждение H.264, поскольку оно также отображается при использовании видеокодека VP9.
Что означает это предупреждение и что мне нужно сделать, чтобы это исправить? Благодарю.
