FFMPEG 2.1.1 & X264 0.138, bugfix in DJDEV 2.04 (Announce)

Hi,
here's my update of FFMPEG & X264 A/V encoders package https://sourceforge.net/projects/ffmpeg-x264-dos/files/
I also enabled some additional filters in FFMPEG (avresample and postprocess).
I assisted to Juan Manuel Guerrero with debug current DJDEV 2.04 CVS and he found a tail pointer bug in function strtod() that caused malfunction of early FFMPEG 2.0.1 build that was discused here and I was forced to revert to older DJDEV CVS from 2011. Now the bug is fixed and all seems to be working. I uploaded the recent DJDEV also on SourceForge. Let us know if you find some problem.

Here's a shot list of updates and new features of DJDEV 2.04 CVS 19.11.2013
- compiled it with the latest update of gcc482 and -O2 optimization.
- implemented floating hex support for strtod, strtof and strtold. Fixed tail pointer bug.
- implemented strndup and strnlen.
- improved DXE3 support so that DXE works again with gcc46N and later versions.
- replaced/rewritten ctime.c so that it works again with newly introduced zone info data base format. Updated zone info data base files to version tzcode2013d.
- implemented [l]lrint[f|l], round[f|l], [l]lround[f|l] and isinfl, isnanl and finitel for libm.a

Post reply

Thanks for all the DJGPP work. I really want to start using it again. However, all the half-way fixes of 2.04 and half-harmful bugs of 2.03 mean I have to pick and choose which version I want to use depending on which bugs I want to be affected.

Which bugs you mean? I think the decision is simple (for me) djdev 2.03 development is stopped forever. It works but lack some new functions. If you find a bug don't expect anybody to fix it. Djdev 2.04 is targeted rather to run under NTVDM but I don't have issues under MSDOS. It lives at CVS, sometimes someone commit a patch or update so there is some chance for slow evolution and bug-fixing. But of course you can simply have both installations and switch between them (change path) if you need. I use djdev for ~10 years since it was released.

My statement about bugs and fixes was more about things that work/compile on 2.03 but won't work/compile on 2.04 and/or an incompatible with 2.04 (and vicea versa). It's not a whole lot overlap in that space (I admit), but I have run across a couple allegro bits and some of the user land libraries/programs. I didn't get a chance to document it when I ran across and should try to the next time I get some time to work on DOS stuff. That might just happen with an 86duino, though.

Thanks (NOT tested) :-)
