大家好，
我在实现从A8读取1920x1080的YUV422I_YUYV格式的视频帧然后经过DEI处理（BP模式）转换为YUV420SP_UV格式的视频帧，最后再经过decLink进行压缩。
IPC Frames Out (A8)

IPC Frames IN (M3)

On-Chip HDMI |
IPC Bits IN (A8)
可是在运行时，PC机终端屏幕打印消息显示：

CPU不支持1920的宽度，自动将宽度降到960。可是DVR_RDK中提供的demo中有一个示例： VCAP + VENC + VDIS - HD Encode ONLY，c文件是mcfw/src_linux/mcfw_api/usecases/multichhd_vcap_venc_vdis.c 这个示例显示1080p的高清视频是可以进行DEI处理的，这是什么个情况？
