problem with v4l2src

[tobatrance]

Hi,

I got a problem with my v4l2 pipeline. I'm using this one in my application:

v4l2src ! "video/x-raw, framerate=60/1" ! appsink

I'm fetching frames from a USB HDMI connector which is listed as working
properly with uvcvideo. However,  after some time of working it happens that
I get the following warning in my log:

0:00:23.829022849  1063 0x557125fe6e30 WARN                 v4l2src

gstv4l2bufferpool.c:1946:gst_v4l2_buffer_pool_process:<v4l2src:pool:src>
Dropping corrupted buffer without payload

while the last 2 messages are repeated a couple of times. After that the
streaming immediately stops.

this happens in 1.8.3 and 1.14.1. Any idea or better recommendation how to
fix that?
