ijkplayer播放RTSP实时视频流花屏问题，希望有高手可以指点一二

我使用K0.7.5版本的源码，根据教程编译出apk后，在真机播放RTSP实时视频流时出现花屏现象，上半截屏幕还可以看见正常图形，下半截图像就全糊了，android studio输出的日志一直重复如下内容：

请教一下是否编译缺少了什么选项？

Start by reproducing playback from the K0.7.5 source-built APK on a physical Android device using the reported RTSP stream. Review the repeated IJKMEDIA NAL-unit, start-code, and bytestream-overread logs alongside the build tutorial and options. Done means determining whether a build option is missing and documenting a confirmed cause or reproducible next step.
