我的板子是6437的，看到H264_Encoder_DM6437_UserGuide.pdf文档中说道
The codec component is released as a compressed archive. To install the
codec, extract the contents of the zip file onto your local hard disk. The zip
file extraction creates a top-level directory called
100_V_H264AVC_E_1_10_00, under which another directory named
DM6437_BP_001 is created.
但是我这边的dvsdk中没有这个压缩包，请问从哪里可以下载到
