im just building a new ingex from cvs and I get a segmentation fault when launching the dvs_sdi binary or even the dvs_dummy.
The backtrace indicates that the default constructor for Timecode is broken.
Program received signal SIGSEGV, Segmentation fault.

This call is made from the global instanciation from here dvs_sdi line 188:
188 Ingex::Timecode master_tc; // master timecode
I'm a bit puzzeled what may have caused this or is just my binary doing wrong?
gcc -v shows:
gcc version 4.7.2 (Debian 4.7.2-5
with default settings (default debian compiler collection)
Oh dear, I will look into that.
That's nice i'll have a look into it too but I don't know the source that well of course ;)
OK, I think the problem is that I made the Timecode class variable length, which doesn't really work in ring buffer. Will work on fix.
I guess feeding the default constructor with valid initial values should do the trick, but im not sure what the system expects as valid initial values for a timecode class.
Also I haven't had the time to check the history of the timecode class and track down was was changed.
Should be fixed now.
Okay thank you very much.
I'll have a look into it asap :-)
this update broke 'bmd_sdi' compilation.
(due to class changes from 'Timecode::Format' to 'TimecodeFormat::EnumType'
The dvs contructor is fixed and dvs_sdi is working as intended as far as I can tell, many thanks.
Michael, bmd_sdi compilation works ok for me now.
