android-MediaRecorder在新的Google Glass固件(XE19.1)媒体服务器上无法正常工作,死于错误100

概述我为GoogleGlass制作了一个视频录制应用程序.在Google发布固件XE19.1之前,该应用程序运行良好.我还有另一个固件为XE18.11的GoogleGlass.该应用程序仍可在带有XE18.11的GoogleGlass上运行.我收到以下错误：07-3015:39:32.273:V/MediaRecorder(17101):video.h264enc.profile

我为Google Glass制作了一个视频录制应用程序.在Google发布固件XE19.1之前,该应用程序运行良好.我还有另一个固件为XE18.11的Google Glass.该应用程序仍可在带有XE18.11的Google Glass上运行.

我收到以下错误：

我试过但没有用的东西：

>尝试MediaRecorder example from Google.仅适用于较旧的固件
>恢复出厂设置的谷歌眼镜
>尝试是否在录制前开始预览.都可以在较旧的固件上运行
>将SurfaceVIEw更改为TextureVIEw.都可以在较旧的固件上运行
>看了changelog GDK XE19.1
>搜索错误

这很奇怪,因为即使Google示例也不起作用.这是将SurfaceVIEw更改为TextureVIEw之后的代码：
