<v4l2src0:pool:src> Dropping truncated buffer, this is likely a driver bug.

[Aniket0987]

Trying to capture I420 FHD at 5fps on RP4.
Pipeline is as follows,

v4l2src device=/dev/video0 io-mode=dmabuf !
video/x-raw,width=1920,height=1080 ! videoconvert ! video/x-raw,format=RGBA
! videorate ! video/x-raw,framerate=5/1 ! queue leaky=downstream !
v4l2h264enc capture-io-mode=dmabuf ! video/x-h264,profile=main ! h264parse
splitmuxsink name=mp4mux max-size-time=60000000000 max-size-bytes=134217728
location=/tmp/vid_ sync=false ! queue ! mp4mux.video

After a certain time, v4l2src starts dropping everything.

Is there any issue in my pipeline or is it a v4l2 driver bug?
