Recently, the video is decoded to generate yuv data and then jpg images. The previous scheme is yuv-rgb-bmp-jpg, which is very slow. The calculation time is about Ms, multiple clicks on a photo may lead to video screen latency. Therefore, you can only use another method to query libjpeg on the Internet. Therefore, we plan to use libjpg-turbo to convert yuv to jpg images. The following is the use of ndk to cross-compile libjpeg-turbo to generate a libj
