Hi, when I use vpp to mix the pictures, I got two input streams to mix, but the output picture is just get the first stream and miss the second stream,the param set like :
stream=1.yuv
width=640
height=480
cropx=0
cropy=0
cropw=640
croph=480
dstx=0
dsty=0
dstw=640
dsth=480
framerate=25
fourcc=nv12
stream=2.yuv
width=640
height=480
cropx=0
cropy=0
cropw=640
croph=480
dstx=0
dsty=0
dstw=240
dsth=160
framerate=25
fourcc=nv12
How could this happen? My computer type is thinkpad e431, Graphics Card: Intel(R) HD Graphics 4000
And This Works well on another computer thinkpad e440 with Graphics Card: Intel(R) HD Graphics 4600
