As cameras tend to have a quite specific set of capabilities (specific framerates for each resolution), getting the peer caps filtered by our probed caps can cause a big increase in the caps size which slows down things quire a bit. As for negotiation v4l2 iterates through the caps of the peer to find the first intersection with the probed caps, getting the fully expanded intersection of capabilities is not useful. Using the same testcase as for bug #702632, adding this patch on top of the patches suggested there speeds up getting the inital frame from around ~14-15 seconds to around ~3-4 seconds. https://bugzilla.gnome.org/show_bug.cgi?id=702638 |
