gst1.0-fsl-plugin multiple instances of vpuenc

I have found a potential issue with the GStreamer 1.0 implementation of vpuenc relating to multiple instances of vpuenc. I have created a very simple gst1.0 command line that reproduces the issue:

 

gst-launch-1.0 videotestsrc num-buffers=100 ! tee name=d \

        d. ! queue ! vpuenc ! "image/jpeg" ! filesink location=/tmp/file1.jpg \

        d. ! queue ! vpuenc ! "video/x-h264" ! filesink location=/tmp/file1.avi

 

If I repeatedly run this, 1 in 7 or so runs result in the following:

Are multiple instances of vpuenc supported? Is there anything I can do to overcome this issue?

 

Thanks,
