使用ffmpeg解码基本HEVC流

Question

我已成功编译并安装FFMPEG_2.1源代码。我知道2.1版以后的ffmpeg支持HEVC解码器。我使用HM 10.0和HM 11.0 HEVC参考代码生成了.bin文件。

但是，当我给这个bin文件作为输入到ffmpeg我得到一个输入/输出错误。

ffmpeg -i Johnny_1280x720_60qp22.bin out.yuv 

如下图所示的上述命令的输出：

，我已经使用这个命令下面给出

谁能告诉我为什么我面对这个问题以及我如何纠正它。

这是我得到的使用HM 12.1编码的hevc序列的输出。

$ ./ffmpeg -i kimono_hevc.bin out.yuv

请注意，在我的例子中，我得到

Stream #0:0: Video: hevc, yuv420p(tv) 

而你得到：

Stream #0:0: Video: bintext, pal8, 

HM10是旧的，除其他外NAL结构变化。任何不使用最新的理由？
