Как правильно транскодить на AMD при помщи VAAPI?
www.linux.org.ru/forum/desktop/14459465
Низкая скорость кодирования H264 в RX 580 это нормально?
h264_vaapi - пробовал под убунтой 19.10 x64
Результат: скорость (fps) такая же как и у CPU
Решил сделать пару простейших тестов их родных amd кодеков h264_amf и hevc_amf
Насколько я понял, под линукс эти кодеки тоже есть (https://github.com/GPUOpen-LibrariesAndSDKs/AMF/releases), но я их не тестил в убунте.
Запуск из консоли под Windows10.
