TI中文支持网您好 TIers：
接法是： VIP0_A , 接了一路 1920×1080 30fps。
VIP1_A , 接了一路 1280×1024 60fps。
—————————————————————————————-
软件配置了两个 IVAHD，各编码一路。
LINK 是： CAP –> OUT VPSS —> IN VIDEO —> ENC —> BITS OUT —> HOST
请帮忙看看如下问题，谢谢。
有没有 两路独立高清编码 的 demo ？ 谢谢
问题1： dm8148 是否支持两路高清同时编码 ？
问题2： 第二个通道的码流获取的不对，size太小了，播放也没有图像。日志如下：

Chris Meng：
你好，
DM8148的编码性能大概是1080p60多一点，你现在的配置可能会超出编码能力。两路1080p30编码是可以的。
请问你使用的是DVR RDK 4.01么？如果是，里面的DM8168 有一个HD Encode Card Use-case可以参考。
