[参考译文] TDA4VM：J721S2 V4L2 H264编码器问题

TDA4VM: v4l2 框架下encode在新的sdk8.4和sdk8.6不能正常工作

hi ti：

    我之前在sdk8.1上调试通过了视频编码器，能够正常运行。我的修改是基于git.ti.com/.../videnc-test-app.git下载的代码调试。在sdk8.1版本上，我可以配置输入通过普通内存或者dma的方式，输出通过普通内存，都可以正常运行。现在我们升级了sdk，在sdk8.4上，输入输出都采用普通内存的方式，是能够正常运行的。但是输入用dma的方式，输出用普通内存的方式，却无法正常工作了。在sdk8.6上，均无法正常工作。包括通过上述地址下载的原始代码编译出来的app，也无法正常运行。我想知道怎么修复在新sdk上的问题，或者有没有能够在新sdk上运行的demo供参考。我们最终的需求是输入需要通过dma的方式，输出可以通过普通内存的方式。

   期望早日回复，感谢！

    这是在sdk8.6上运行的log
