ARV_GV_STREAM_SOCKET_BUFFER_AUTO causes frame timeout on small images
Describe the bug When using ARV_GV_STREAM_SOCKET_BUFFER_AUTO option with small image sizes (images that are transferred in only one packet, a TIMEOUT is generated even though packets seem to be properly received. Removing the ARV_GV_STREAM_SOCKET_BUFFER_AUTO option makes everything work again (using default socket buffer size).
To Reproduce Only tried this on a SI-1900 camera, but simply executing the arv-camera-tester using a small width and height and setting the '-a' option reproduces.
Expected behavior Images are streamed and received as expected.

Hi,
Thanks. The auto buffer size code should have a lower limit in the value applied to the socket size.
No idea yet. I have to check the code. The current one probably does not take into account the udp packet format cost.
