I tried again, and there's a possible further regression - though I have no idea whether it's ffmpeg or the newer patches here. Just thought I would mention it, as I haven't had time to look into it further yet.
I can confirm this is a regression with the current patches, the last set works with the same command.
The regression is that when asking for a bitrate there is now a floating point exception, -qp still works (comes out at 0 like gst). andy [vce-tests]$ gdb /mnt/sdb1/Gits/ffmpeg/ffmpeg_g GNU gdb (GDB) 7.10.1 Copyright (C) 2015 Free Software Foundation, Inc.
