프로젝트 https://github.com/iiordanov/bVNC gstreamer sdk (http://docs.gstreamer.com/display/GstSDK/Installing+for+Android+development)를 사용 중입니다. 그것에 사용되는 jpeg 라이브러리는 jpeglib입니다. mjpeg 디코딩 성능을 향상시키기 위해 jpeglib를 libjpeg-turbo로 대체하려고합니다. 내가 어떻게 해?gstreamer sdk android를 사용할 때 libjpeg를 libjpeg-turbo로 바꾸는 방법은 무엇입니까?
1, jni/src에서 Android.mk 파일을 변경했습니다. 아래는 변경된 버전입니다. gstreamer에서 사용하는 jpeglib를 대체하지는 않았지만 aSPICE에서 사용하는 jpeglib를 대체했습니다. 내가 사용하고있는 bVNC 코드는 v3.3.5입니다.
2 libjpeg-turbo 1.3.0을 컴파일 할 때 --with-jpeg8로 구성해야합니다.
3, 다음은 수정 된 Android.mk입니다 :
