关于dm8168 ezsdk下openmax decode_display例子输出分辨率的问题。

Yu Bin，
请参考e2e上的讨论：https://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/162411。
为什么你要使用EZSDK呢？DVR RDK的开放程度更高，修改更方便一些。

Chris Meng ,
 谢谢你的答复。当时我们评估板光碟就是ezsdk，所以一直使用。hdmi分辨率一直可以调，就按你发给我的贴上说的方法一样。但是omx中encd组件只能支持720p和1080p。因为我们需要解码，所以我们想修改decode_display例子，除了720p和1080p，其他都会报错。以下是错误：
input file: good.h264
width: 1024
height: 768
frame_rate: 30
gfx: fbdev disable
codec: h264
display_id: 0

我想问能否有办法修改decode_display能让他支持其他分辨率。是不是要增加对其他分辨支持要修改hdvicp2的程序，但是在ezsdk中找不到hdvicp2的程序。再次期待你的答复，谢谢。

Bin Yu，
抱歉EZSDK我不是很熟悉，而且M3的源码代码也没有。
从错误看不出来，错误是在编码侧，还是在显示侧。现在显示支持1024x768么？

谢谢，你的答复，这个问题已经解决。
