rga linux版本的驱动是根据v4l2 m2m的api写出来, 如果需要直接操作v4l2 device, 最好是参考驱动里的rga.c和v4l2 m2m的userspace demo, 目前我们并没有提供任何的wrap lib. 6. FAQ 6.1. I have use mppvideodec/mppvideoenc, however, it is slow. 检查下你是不是用了videoconvert, 如果使用了videoconvert,...
拿到fd之后,使用importbuffer_fd可以转换成功,1920x1080 这个耗时大概5ms voidrga_convert_with_fd(intsrc_fd,intsrc_size,intdst_fd,intdst_size,intwidth,intheight) {rga_buffer_tsrc = {};rga_buffer_tdst = {}; im_rect src_rect = {}; im_rect dst_rect = {};rga_buffer_handle_tsrc_handle,...

video/rtsp/camera -> decoder -> 2d convert -> opencv -> display sink Implement 首先opencv在gstreamer是有plugin的, 但是从应用开发的角度, 这样不够flexible : plugin里的东西和外界是封闭的. 在实现上, 更建议使用Appsink和AppSrc, 这些模块, 在你的应用里, 是以Thread的形式存在的, 开发起来要更方便....
