TI中文支持网大家好！
请问一下dm365支持视频的缩放的功能吗？现在要想用dm365 编一个720p的264的编码，然后以任意分辨率(小于720p的分辨率)输出到电视上，是不是要用到resizer的功能呀？
IMP_MODE_SINGLE_SHOT、IMP_MODE_CONTINUOUS 两种模式到底是是什么意思，有什么区别呀？
谢谢！

现在用dmai下的resize demo程序(dvsdk_2_10_01_18\dmai_1_21_00_10\packages\ti\sdo\dmai\apps\video_loopback_resize)，运行时出现了以下信息

请问哪里出现问题了？导致了Resize_create 创建失败？我在bootagrs已经配置成 CONTS模式，我也试配置成sigle shot mode，但是程序仍然运行不起来，只是提示的错误信息不一样("Operation mode doesn't match with current hw mode")。
