How to change the horizontal screen to the vertical screen when the ENC encoder RTMP pushes the stream

Today, a customer asked this question. I didn't pay attention to it before, so I tried it myself and posted the method. Next time, if a customer encounters this problem, there will be a basis for reference.

The original video is 1920*1080, as shown below:

Rotate 90 degree configuration method:

The first step into 编码设置the 高级编码参数will 分辨率was changed1080*1920

The second step proceeds 编码设置to 视频参数the 旋转setting 90

done, RTMPplug flow preview:

Black screen compensation method

The first step into 编码设置the 高级编码参数will 分辨率to 1080*1920

the second step, into the 视频混合interface, will 混合开关open, if desired HDMI output, open HDMI开关, select Mixas the 视频源following figure:

The second step, disposed in a mixed video mixing page layout, as follows:

the Change the layout in the figure 上下, and then 自定义布局select the original layout 上下as follows:

[{
    
    "x":0,"y":0,"w":1,"h":0.5,"index":0},
{
    
    "x":0,"y":0.5,"w":1,"h":0.5,"index":1}]

After the change:

[{
    
    "x":0,"y":0,"w":1,"h":0.33,"index":0},
{
    
    "x":0,"y":0.33,"w":1,"h":0.33,"index":1},
{
    
    "x":0,"y":0.66,"w":1,"h":0.33,"index":2}]

After saving, we check the RTMPpush effect:

As shown in the figure above, the upper and lower parts have already compensated for the black screen. I just give an example. If you want to customize the layout, you can learn the custom layout parameters.

End. Thank you for your support and praise!
