TI中文支持网大家好。我在dm816x平台上，把从ip camera上接受的h.264视频流用mcfw框架显示。在最开始的几帧会出现类似如下错误，但是错误代码不固定，然后才正常显示出来，请问是什么原因？还有，我把这些视频帧保存在文件中，然后再从文件读取出来进行解码显示，为什么也会出现下面的错误，而且不是前几帧出现，是每帧的出现，视频也显示不出来?似乎是跟decoder里面的帧缓存有关系。切换一个视频源的时候，能不能把该解码通道的帧缓存清空呢？

hui qiu：
感谢Haijun Guo.那如何flush decoder呢？
hui qiu：
只是前面的几帧会出现错误，后面就不会了，而且用vlc是可以播放的，码流应该没啥问题。而且如果一开始播的是一个视频源传过来的码流，后面换成另外一个码流，也会出现错误，而且视频没有显示。这两个码流单独显示都没问题的
Haijun Guo：
如果你在使用DVRRDK，可以参考Declink_h264DecodeFrameBatch。
