能不能用ndk-build编译个库给我们啊，真的很需要。

这个libjpeghwdec.so库没有源码，无法重新编译，你可以试试用mm的方式在SDK里面完成编译，或者你可以提供一下你的spice源码给我们试试~

帮忙分析下，红色部分是我添加的

请问有没有这个库的使用说明，我现在用的frameworks/base/media/tests/omxjpegdecoder/jpeg_decoder_bench.cpp生成的可执行程序，根据打印信息，得到if(hw_jpeg_decode(&hwInfo,&outInfo, &reuseBitmap, bm->width(), bm->height()) >= 0)，这个hw_jpeg_decode调用返回的是负值。

请问有调用hw_jpeg_decode接口的demo吗？

楼主，请问您的测试Demo写完了吗？能否借我参考！谢谢～

不好意思，调用hw_jpeg_decode接口的demo没有实现啊

樓主，你也在弄spice嗎？是基於spice-gtk麼？播視頻卡噸，您是如何實現硬件解碼的？能否提供幫助與支持？謝謝～
