Error h264_vaapi works but there is scaling but why

[Richárd Nemes]

Hi, why does it scaling the video?

libx264 doesn't resize it, but vaapi does.


libx264 works, no scaling
code:

PHP Code:

{
        "level": 30,
        "ui": 255,
        "uilp": 255,
        "platform": 1,
        "device": "/dev/dri/renderD128",

libx264 has no scaling problem here.
   

h264_vaapi scaling problem.
