waylandsink: support only RGB formats
I use gstreamer 1.22.5 on Ubuntu 23.10. gst-inspect shows next formats for waylandsink
:
Pad Templates:
SINK template: 'sink'
Availability: Always
Capabilities:
video/x-raw
format: { (string)BGRx, (string)BGRA, (string)RGBx, (string)xBGR, (string)xRGB, (string)RGBA, (string)ABGR, (string)ARGB, (string)RGB, (string)BGR, (string)RGB16, (string)BGR16, (string)YUY2, (string)YVYU, (string)UYVY, (string)AYUV, (string)NV12, (string)NV21, (string)NV16, (string)NV61, (string)YUV9, (string)YVU9, (string)Y41B, (string)I420, (string)YV12, (string)Y42B, (string)v308 }
width: [ 1, 2147483647 ]
height: [ 1, 2147483647 ]
framerate: [ 0/1, 2147483647/1 ]
I tried to use videotestsrc
format I420 with waylandsink
:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=(string)I420" ! waylandsink -vv
Setting pipeline to PAUSED ...

and format NV12:

and no problem with videoconvert
