DOS ain't dead

Hi,
I recompiled recent FFMPEG and X264 A-V encoders for DOS.
http://sourceforge.net/projects/ffmpeg-x264-dos/files/

I know there's new FFMPEG 2.0 but it would require messing with all the configure and patching process again. So this is just minor update, probably the last one from 0.10.x branch.

I got it. Thank you. :)

I use FFMPEG quite a lot in DOS.

I also use FFMPEG often, and really appreciate the DOS binaries you have provided. Is ver 2.0 impossible to compile for DOS platform?

> Is ver 2.0 impossible to compile for DOS platform?

I didn't tried yet. I think it would be possible after some manual configuration work. As configure script doesn't work for me under DJGPP I use configure from MINGW under windows and then manually modified configuration files and makefiles to work with DJGPP. It's a lot time consuming, many compile tries and frustrating... It would be better if someone experienced with configure could fix/extend DJGPP to configure it under DJGPP directly. It depends on maly unix tools maybe using a DJGPP crosscompiler under Linux would be better way...

I tried to configure and compile v2.0 (without ext. libs) and ended with strange error

Do you know about some utility that can trace commands passed to shell?
I need to see what program is missing instead of useless "bad command or file name"

DOS gives me freedom to unlimited HW access.

I found the problem is caused by make passing too long (>14000 chars) ar command (lot of .o files) to cmd.exe that cannot handle it and truncate it to 8191 (limit for WinXP). I tried to run bash first and then make but didn't help - why? when I run bash and paste long ar line it will pass and make .a library successfully.

DOS gives me freedom to unlimited HW access.

Well, with kind help of Eli @ DJGPP google group I was able to overcome cmdlide length limit by increasing make, ar, rm executables stub transfer buffer to 32kB using stubedit. Good, I learnt something new...
Now here's the first working build of FFMEPG 2.0 currently without any ext. codecs (no x264, etc) but can be tested for mpeg, mjpeg, etc...

Wow, RayeR you are a dedicated and talented man! I knew about the 8192 byte limit but not how to overcome it for very large make files > 8 kb.

I'm very thankful for the 2.0 build and I'll be glad and happy to test it!

Hi,
I just uploaded FFMPEG 2.0 + X264 0.135 final version. It includes the same external codecs like older 0.10.x version. Speed of h264 compression is same because of used same libx264. I also upgraded to DJDEV 2.04 CVS 20.7.2013 kindly compiled for me by Juan Manuel Guerrero, also uploaded at SourceForge. Enjoy the testing :)

More verbose debug output?
I tested it only on C2D machine to encode mpeg1 to h264 and it works, I didn't on any ancient machine.

Wish I could test it here.

Is there a bundle of just the binaries available ?

All I have been able to extract, from any of the posted archives, is sources.
And from the .rar, all I got was a bunch of empty directories - no actual files at all.

Scratch all of that.

That's not the version you were speaking of.

Got v2.0 and it does not encode.

You didn't specify the output codec, maybe this is now illegal.
What if you enter
ffmpeg.exe -i example.mpg -vcodec libx264 example.avi
I used this in my TEST.BAT as you can see...

It's packed by winrar 3.80 you probably need to update your (un)rar. I guess that commandline winrar should run under HX.

Hm, from what I tried it seems that most of internal encoders doesn't work except e.g. yuv4. Those in external libs like h264, theora or vp8 works fine. I have no idea what was messed during my modifications, I didn't disable any codecs in config files, eg:
#define CONFIG_WMV1_ENCODER 1
#define CONFIG_WMV2_ENCODER 1
but it still doesn't encode wmv1 while old version did. Someone else could help?

Probably.

I don't use HX, and I won't run Windows.
I could have used Linux to unpack it, but as it doesn't seem to be working there would be no point.

After some messing around with it I got an idea to just recompile old FFMPEG 0.10.7 and try if still works. And gues what - it didn't! Bingo! I exactly know what I had changed. I upgraded to latest DJDEV 2.04 CVS. So I quickly reverted back the libc.a, relink the binaries and it worked again. Also FFMPEG 2.0.1. Fortunatelly I had a backup of older CVS DJDEV from 26.10.2011 that I have been successfully using so I reverted it completly back and also replaced the package on SourceForge.
I uploaded new version of FFMPEG 2.0.1, also bin-only package. It should have same features and codecs like 0.10.7. I keep buggy FFMPEG 2.0 package there for bug tracking if someone from DJDEV developers will be interested.

You can just use RAR32, it is a command line RAR version which natively runs under DOS and OS/2 using EMX extender.

DOS-u-akbar!

It is strange. I can't encode or decode Monkey's Audio or Wavpack, but can encode other audio formats (mp3, mp2, aac, ogg, flac) only and not video codecs with 2.0. Straight Demuxing and remuxing (= stream copying) avi / mpeg2 / mpeg4 seems to work, but not encoding between video codecs.

Is the wavpack (.wv) wrapper built into your 2.0 or 1.2.0 DJGPP binaries?

See for the info on a wavpack wrapper encoder for FFMPEG:

http://patches.libav.org/patch/39107/

Are external codecs available on your FFMPEG binaries?

The latest BTTR port of UnRAR (DJGPP) is "V3.8(0).5" while the latest UnRAR (IIRC, also compiled by rr with DJGPP) hosted at RarLab.com (under Extras) is unrar38b.zip.

Since RayeR is using WinRAR 3.80, it should be compatible. However, keep in mind that RAR 3.93 is "last" for DOS (obsolete). EMX is slightly buggy with 1+ GB machines (but RSX is slightly better), and its C++ (at least for DOS + OS/2 hybrid) is (probably still?) much much older than current/beta DJGPPs.

I have no idea if UnRAR still compiles with DJGPP (IIRC it used to need /backwards/ from G++ 4.2.3 or older). I guess I should try, I like compiling (but I hate when stuff doesn't work!). UnRAR 4.x added a lot of Unicode stuff (presumably unfriendly to DJGPP), and latest sources for UnRAR are unrarsrc-5.0.10.tar.gz. Latest RAR is either 4.20 or 5.00 beta 8. IIRC 5.0 format changed compression incompatibly again, so caveat emptor.

(dumb answer) Maybe RayeR should just use .7z!

No, there's only decoder, encoder needs libwavpack.

UPDATE: Well it was not so hard to compile complette wavpack so encoder is now available, not tested. Go ahead :)

FFMPEG 2 seems to run OK in plain MSDOS 6.20.

Converts .flv to .mpg at least as fast as previous FFMPEG.

Noted some parameters are different e.g. "-sameq" has been dropped, must now use "-qscale 0" to keep picture quality, but I can live with that.
Will have to look for a matching man for FFMPEG 2.

This will get a good workout over the next week or so. :)

THANK YOU... it works perfectly :)

COOL, seems to work now

Any progress with fixing bugged DGJDEV (DGJPP mailing list) ?

Low priority wish for next FFMPEG version: add/enable OPUS audio and SH** / Schredder / Schroedinger video codecs.

Unfortunatelly no, Manuel tried to recompile my configured ffmpeg package but got some strange error that I also don't know what to do with it so he has no working test case to debug it.

I just saw the update to your post! I downloaded the new binaries and they work perfectly! THANK YOU

Now we have latest Wavpack encoder and decoder binaries for DOS! 4.6.1.

All encoding that I tried works very well now without the behavior reported previously in the old 2.0.0 binaries.

FFMPEG is Pandora's Box for all of us who like to play with audio and video conversion!
