libyuv旋转90度画面模糊

使用libyuv对视频原始帧进行90度旋转，得到的画面是模糊的。只有视频分辨率 在长跟宽一致的时候才有效。有人遇到这样的问题么

转换1920x1080分辨率的帧软件崩溃

我做Airplay投屏使用了libyuv库，投屏分辨率达到1920x1080时，软件会崩溃，麻烦大佬帮忙看下，谢谢！
代码如下：
libyuv::I420ToRGB565(frame->data[0], frame->linesize[0],
frame->data[1], frame->linesize[1],
frame->data[2], frame->linesize[2],
(uint8*)buffer_dest, dec_ctx->width * 2,
dec_ctx->width, dec_ctx->height);
