As it says, this might just mean things run too slow in your VM. Could also be an issue with latency reporting/handling if you have live elements in your pipeline. Try setting sync=false on v4l2sink.</pre> </blockquote> Is likely to be the original live lagging sometimes.. I'll try to use sync=false when I'll fix the above problem.

It's part of gst-plugins-base 1.1.1 an should have been installed into /usr/local/lib/ as well. Maybe your system isn't set up properly so that it doesn't find it there? Try setting the LD_LIBRARY_PATH environment variable to /usr/local/lib/ or adding that directory to /etc/ld.so.conf* (and run sudo ldconfig). > gstbasesink.c(2686): gst_base_sink_is_too_late (): > > /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: > > There may be a timestamping problem, or this computer is too slow.
