TI OMAP4430 openmax解码获取不了组件句柄失败问题？
各位兄弟姐妹好啊
请问有哪位做过android平台TI 下的openmax的视频硬解码播放功能？
C/C++ code //打开加载libomx_sharedlibrary.so成功，其他初始化也没有问题 //lib_name 为"OMX.TI.DUCATI1.VIDEO.H264D"和"OMX.TI.DUCATI1.VIDEO.DECODER"if ((pOMXInterface->GetpOMX_GetHandle())(&ComponentHandler, lib_namectx, funcs) != OMX_ErrorNone) { LOGE("GetHandle lib_name: %s Fails!\n", lib_name); return NULL; }
这段代码总是失败，总是获取不了lib_name的句柄。
我知道日志里面有很多错误，但是不知道还需要调用哪些相关设置和函数才能正常取得此句柄，
或者我本身的方向就错了。但是此代码和流程在tegra2上能正常运行。
请各位兄弟姐妹指点或给点建议，一起讨论讨论下？
谢谢！
期待各位的回帖？
以下是log日志

的从这里看起，好象是找到component ，你的视频是什么编码的？
[解决办法]
你应该吧MEDIASERVER和相关RPC/IPC的驱动的权限改为755，
[解决办法]
公司开发正巧也遇到这样的文题，同求答案，谢谢啦。
[解决办法]
你这里的render组建是指OVERLAY的硬件显示吗，就是那个libstagefrighthw.so
[解决办法]
android里面的媒体框架没有使用OMX的render组建，而是使用的overlay来显示视频，是现在libstagefrighthw.so里面
[解决办法]
TI可能不完全遵循OMX的标准吧
