PointGrey BFLY-PGE-14S2C-CS packet size adjustement support #425

Open EmmanuelP opened 3 years ago

arv_gv_device_auto_packet_size doesn't work with this device, while GevSCPSFireTestPacket seems to be supported and to work at least once:

Here, initial check works:

By inserting a 1 or 2 second sleep between FireTestPacket commands, it seems to work, but not reliably.

When it does not, g_poll times out, with n_events == 0. None of the feature access command return an error.

May be a firmware issue ?

Firmware updated with latest release, the issues persists.

Auto packet size adjustement does not display errors on Flycap Windows, but also does not seem to really adjust anything.
