Я пытаюсь включить Intel VAAPI в OPENCV, потому что я хочу сделать быстрое воспроизведение видео с использованием OPENCV во встроенной среде (в настоящее время я использую плату LattePanda), но функции OPENCV Videocapture() и imshow()очень медленно.
Чтобы решить эту проблему, хотя я использовал многопоточность, этого было недостаточно для исходного fps (30 кадров в секунду).
Поэтому я подумал, что способ воспроизведения исходного fps - это использование графического ускорения Intel. (VAAPI (i965), а не MediaSDK (iHD))
Итак, скажите, пожалуйста,Как я могу сделать OPENCV на базе Intel VAAPI?
Команда CMAKE, которую я использовал следующим образом:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON \
-D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D \
BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D WITH_GSTREAMER=ON -D WITH_FFMPEG=ON -D WITH_VA_INTEL ..
Мой результат cmake OPNECV такой:
