*Проблем несколько:

1) Сборка firefox по умолчанию (91.13 чего-то там, e2kv6) -- говорят не желает элементарное - проигрывать YouTube 360p, в реальном времени;

2) MPV, VLC, Mplayer при старте воспроизведения видео MP4, без доп.параметров, вылетают с различными ошибками (пользователь от имени которого стартует воспроизведение, по умолчанию, состоит в группах audio, video и др.):

Все логи прикладываю ниже; Догадки не строю, но тех модулей, что проскакивают в логах, в сборке Симли 10.2 для X-сервера как-будто действительно не существует?! / в том числе модуля ядра pvr.ko, используемого в OSL.

* * *

Подскажите, пожалуйста, когда примерно ждать или какой вариант p10 использовать, чтобы юзерские задачи обычного просмотра видео штатно закрывать на Elbrus e2c3?

* * *

P.S> да, по слухам, как-будто части проблем (проигрывание 360p Youtube в FF без ощутимых задержек) нет в более ранней версии Симпли 10.1; но для проигрывания сохраненных на диске MP4-видео все одно необходимо вручную указывать софтверный вывод через X11, чтобы успешно посмотреть -- что, кстати, позволяет вполне свободно, без задержек просматривать 2K/1K/FullHD 25...29fps (h264) на 2-х ядрах К1891ВМ06 без аппаратного ускорения!
