Steve Underwood 46ec57c415 The gettimeofday() function spandsp provided for Windows apparently falls over 
after 25 hours. I guess not many people are inserting header lines on FAX pages.
Hopefully this update fixes the problem.

Steve Underwood 93bb5ca5c7 Removal of numerous trailing spaces, to tidy up spandsp in line with the master 
version.
 2013-03-14 05:04:43 +08:00
Steve Underwood 45eaaf4178 Spandspi's FAX engine now gives separate size and resolution information about 
the images on the line and the images in the file. The ties in with the recent
addition of image resizing and flattenign for colur images.
mod_spandsp has been changed to make use of the additional information.
 2013-03-10 20:55:21 +08:00
Steve Underwood 1d289b3617 Chnaged T.30 x-rex, y-res, width vetting to be more rigorous. 
Various little tweaks to spandsp
 2013-03-09 22:19:47 +08:00
Steve Underwood 560e70f27d Some minor tweaks to T.30 page handling 2013-02-25 22:48:12 +08:00
Steve Underwood 4b46a5511e Eliminated a couple of unused variable warnings in the Broadvoice codec. 2013-02-06 17:07:29 +08:00
Steve Underwood 5144700927 Changed the ..._image_sdp routine to ..._udptl_image_sdp in preparation for 
adding other kinds of image (specifically RTP and TCP/TPKT).
 2013-02-03 16:28:20 +08:00
Steve Underwood 36492e522b Minor tweak to last spandsp change 2013-01-26 03:30:21 +08:00
Steve Underwood 7e79b37c0b Make spandsp's T.38 features tolerate the non-compliant inclusion of data 
in some T.38 packets from Commetrex and Cisco machines.

Steve Underwood f9d4e290cf Tiny mismatch with current code 2013-01-02 22:44:14 +08:00
Steve Underwood 79d578adeb Use a new function in spandsp to access the AT interpreter state inside a T.31 
state, rather than directly probing inside the T.31 structures.
 2013-01-01 23:48:47 +08:00
Steve Underwood c6c03827b8 T.31 now has basically functional T.38 mode - needs more testing, though 
Various modules which lacked routines to get at the sub-structures now
have them.
The tests have been tweaked so they only access internals where essential.
 2013-01-01 23:07:55 +08:00
Steve Underwood e22ce3e611 Improved detection of machines that need fixed point support 2012-12-25 03:14:59 +08:00
Steve Underwood 8f5c772d31 Merge branch 'master' of git.freeswitch.org:freeswitch 2012-12-12 22:05:03 +08:00
Steve Underwood 4bc10ab1dc T.31 now gets somewhere in T.38 mode, although it still needs more work so 
it functions properly in T.38 + ECM mode.
 2012-12-12 22:01:58 +08:00
Steve Underwood 68b8f5f2a7 Various tweaks to T.31 modem, prior to getting T.38 really working with T.31 2012-12-12 03:59:51 +08:00
Steve Underwood 38bf6342fa Various tweaks to spandsp, including starting to add some genuine ARM 
optimisations.
 2012-12-12 03:23:27 +08:00
Steve Underwood bfc3c17bcb Tweaks to the T.31 modem 2012-12-09 13:59:26 +08:00
Steve Underwood dfce47f26d Relaxed the constraints for declaring a clean end of call on FAX receive. If we 
get an EOP, we no longer worry whether the final stages tidy up. This helps
tolerate the increasing number of VoIP calls which hang up before the audio has
flushed down the line.

A few little cleanups.
 2012-11-14 21:53:17 +08:00
Steve Underwood 245c6fc6ce spandsp should now compile in fixed point mode, although the performance of 
the modems will still suck on a fixed point machine.
 2012-10-15 23:29:33 +08:00
Steve Underwood cfce1fd240 The FAX modem receive synchronisation algorithms have been changed to prevent 
occasional false recognition of a fast modem when its really the V.21 modem.
This was sometimes messing up T.38 gateway operation.
 2012-10-11 20:16:45 +08:00
Steve Underwood 1790a8a97a Changed tiff-4.0.2 to demand autoconf 2.63 or later (which is common) rather 
than 2.64 (which is currently a lot less common). This change seems to have
no negative effect, but allows builds to succeed on things like Centos.
 2012-09-03 13:10:52 +08:00
Steve Underwood cbb28e2ae0 Start introducing some meaningful TIFF/FX stuff 2012-09-02 22:10:04 +08:00
Steve Underwood 01646651ab Handle the TIFF/FX better now we have tiff-4.0.2 in the repo. 2012-09-02 21:45:08 +08:00
Steve Underwood b989f8d3eb The tiff-4.0.2 distribution's configure.ac seems to have two lines missing 
AC_PROG_LIBTOOL
m4_include(m4/acinclude.m4)
Adding these and taking out all the Makefile.in files from the tiff-4.0.2
directory seems to sort out the build issues.
 2012-09-02 14:38:13 +08:00
Steve Underwood 4ad110aa5b None of the tiff-4.0.2 Makefile.in files were added before, and it built OK for 
me. That's not happening for everyone, so let's add them all, just like the
tiff-4.0.2 distribution package.
 2012-09-02 12:55:09 +08:00
Steve Underwood 495fd99d5d Patched the new libtiff-4.0.2 code to support TIFF/FX tags and the extra 
compression and colour profile codes that go with them.
 2012-09-01 21:50:47 +08:00
Steve Underwood d1ceeeb7f2 Added missing .update file for tiff-4.0.2 
Hopefully made the last of the tiff-3.8.2 -> tiff-4.0.2 changes in the build files
 2012-09-01 21:32:34 +08:00
Steve Underwood 1603dc70e2 This should have moved us from tiff-3.8.2 to tiff-4.0.2 . The windows builds 
will need rechecking.
 2012-09-01 18:45:56 +08:00
Steve Underwood a2b5af5669 Added tiff-4.0.2 as the first step in moving from libtiff 3.8.2 to libtiff 4.0.2 2012-09-01 17:59:43 +08:00

Steve Underwood ea58df8456 Fixed Cairo's entry in the timezone files 
Changed mod_spandsp so it tries to resolve timezone names like Asia/HongKong
to a POSIX timezone descriptor string, like other parts of FreeSwitch do.
 2012-08-22 22:25:54 +08:00
Steve Underwood fa5569caac A line got deleted somewhere along the line. I didn't do it, honest.
