Я использую https://wiki.qt.io/RaspberryPi2EGLFS для кросс-компиляции qt5.7 qtwebengine на raspberry pi2(raspbian-jessie) и попробуйте использовать qtwebengine/examples/webenginewidgets/demobrowser и simplebrowser для воспроизведения тег видео HTML5
Однако есть две основные проблемы:
Во-первых, для видео нет звука, вы можете увидеть аналогичный вопрос qtwebengine нет звука во встроенном Linux, видео воспроизводится, но нет звука.
Во-вторых, видео лагает, я полагал, что оно не имеет аппаратного ускорения, потому что когда я запускаю программу, она выводит следующее сообщение:
/simplebrowser
ble to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

Я думаю, что не удалось загрузить libGLESv2.so.2, поэтому аппаратное ускорение отключено.
Есть ли у кого-нибудь идеи или опыт по этому поводу?
Большое спасибо.
