DUGL Player 0.4 alpha (Theora/OGG) (Announce)

Post reply

As on the announce title this new version of DUGL PLayer add support for ogg/theora video format. But also completely remove mpeg1/2 video format support.
I'm taking this as an alpha version as i'm planing to add support for vorbis audio, when I'm done with AC'97 sound driver.
Here the download link for the source and binary DUGL Player 0.4 1.1 MB (most for the size is the DOS386 LOONIX.OGG sample) I can upload DJGPP OGG/Theora library binary if some one is willing to recompile it.

Feedbacks are more than welcome :-)

Post reply

Well, the support for .OGG files is, of course, cool. But on other hand the dropped support for MPEG videos is a mistake I think.
OGG format is very good but requires quite fast processor for decompressing.
And the second more important issue is that OGG files are not widely used. Or how many .OGG files have you seen?
I know that f.e. wikipedia use them but except that they are extremely rare. We can, of course, convert another format to them, even in DOS using FFMPEG encoder but it is not very comfortable.

So, I find the MPEG dropping as quite problematic.

Post reply

I dropped MPEG1/2 support for 2 main raisons :
- First MPEG1/2 is a patented video/audio format. So as I'm not sure about the legal issues. Even is DUGL Player is a freeware!
- Second, I used LIBMPEG2 which is a GPLed library, and also I have doubts about legal issues, as DUGL core library is closed source. (DUGL player source available not enough ?!)

For the OGG format, It's right that we need (i guess) two times more powerful CPU to see the same video. But it's :
- Patent free format
- Video file is about 30% of the size MPEG2 file for the same quality.
- theora/ogg/vorbis library are free for any usage.
- Demuxing audio/video is pretty easy not as libmpeg2

What exactly needs to be recompiled and why? :confused:

P.S. I'm no lawyer, but I think MPEG is allowed by Fraunhoffer (sp?) to be encoded/decoded for non-commercial use. I personally welcome OGG support. While it's true that MPEG is more common, it's surely not on merit alone! And Wikipedia is a good enough source (better than nothing, at least) of OGG files (honestly, I don't think I have very many MPEGs, if any, because there isn't a lot of free content out there). Some Linux distros don't provide MPEG playing out-of-the-box due to patent fears, others don't do it out of principle, and still others boast about including "all" media codecs (which is a bit worrisome, even for me, a person who isn't very digital-media-oriented). In short, it's kinda hard to police a world this big, but at the same time, still probably not wise to run rampant either. But I think DUGL is okay either way (although I prefer this one, at least in theory).

Maybe some one want to modify, improve DUGL Player. Or just want binaries of the lib ogg/theora library that I have compiled for another usage.

Any way, my previous support of mpeg1/2 was a bit ridiculous as user have to use an external exe to split the mpeg file into video and audio ! Trying to add my self demuxing I found that i have to understand the low-level binary format of a mpeg file !

BTW I have a question about ffmpeg2theora ! even if i use the "-v 10" for best quality I never get the same quality as the input file :( and the output file is also bigger than the original. Is this a limitation of theora/ogg format or a limitation of the ffmpeg2theora ?

IMHO it's better to adopt new technologies in DOS than keep up all obsolete crap that one can dig out on various "technology" cemeteries ;-)

NO. NO.

Theora is (like MPEG 1/2/4 and others ) a lossy-only codec. Sorry but that's how pretty all lossy multimedia codecs do work, including JPEG :-|

IMPORTANT: To run FFMPEG , FFMPEG2THEORA , FFMPEG2DIRAC and MENCODER in DOS, the secret update of HX from 2009-08 is required , otherwise output file is garbage :-P

ok the ffmpeg2theora parameter -v 10 should be after the name of the input video and it's now much better. But as you said it's a lossy video format so we will never got the same quality as the input file.

I must be missing something here, because I cannot download from that URL.

Still can't from DOS. I had to go to Linux to get the zip.
Which contained version 0.3, not version 0.4, and did not accept OGG files, but did accept .MPG files.

Is the DUGL Player 0.4 alpha anywhere else ?

Yep, got it ! Version 0.4.

And it does play some of my .OGG video files.
But without sound at the moment. :(
Which means it locks up tight with any of my OGG/Vorbis files.

Many thanks for that. :)

Seems to run just fine on my rig. [AMD K6, 600 MHz, 64 MB RAM, SB16]
Plays .OGG files converted from .MPG very well, although aspect ratio is correct only in full-screen.

Still no sound, though. Is sound planned ?

Do you mean 7 fps with smooth and 12 fps without smooth ? as smooth is supposed to slow down things.

vesamtrr enable CPU cache for your graphic card VRAM. You will get more fps with it :-)
you can get it from japheth website HXGUI215 inside the UNSUPP directory. Run it after running your S3VBE20.

Sorry for the ambigiuous answer. I meant that I have a working driver for your SB16. But I have to finish the AC97 driver to start working on adding sound support to DUGL Player.

59 FPS means mostly that your vertical screen synch is enabled. You can disable/enable it by pressing F8.
check on the about dialog if VSynch is ON or OFF.

You are right the Loonix.ogg video is encoded with only 5 fps. So it look like a slideshow.

Quite possibly. :) There is no visible indication as to whether smoothing is on or off.

Got it. Ran it.

On one of my testing .OGG files, the difference seemed to be at most 1 additional frame/sec.
On the other, it went up by an extra 20 fps ! With or without smoothing, it ran at 35 fps.
Remarkable !

It seems the effect depends on the quality of the .OGG file. At low frame-rate, there is not a lot of improvement available, but with high frame-rates there is a noticeable improvement.

Yes you are right, I have to add a configuration dialog or at least display shortly "smoothing on" or "smoothing off". Currently you can check if smooth is enabled or not on the about dialog (Smoothing(ON or OFF)).

I guess, on the case where there isn't a true difference with/without vesamtrrr, that the true bottle-neck is the ogg decoding/YUV2RGB conversion.
In this case you can increase the fps by enabling FAST YUV2RGB (F2) but video quality will be low.

Hope it is optional only.

Well, depends. MPLAYER will slow down the video showing all frames, letting the sound to run away, and when sound is done it keeps repeating last cca 1/2 sec until the video is played also. VLC (non-DOS, OTOH 100% Windaube-7 compliant) will "play" in real-time but drop frame after frame, and since every frame is behind scheduled time when it arrives, it displays no frames at all, leaving just a black rectangle or the very earliest frame frozen. :crying:

So DUGLPLAYER can't beat MPLAYER or VLC by amount of features or supported formats or codecs, but it can well beat them by behavior on slow PC's :-)

There is a boolean set to true. Currently always enabled as there is no keyboard shortcut to disable it.
There is an urgent need for a config dialog.

I don't have a very slow computer to test. But i guess that frame dropping will end to be like VLC if the computer isn't enough fast to get a frame at the good time. I think that you have this kind of computer, So it will be nice to hear that DUGL PLayer is better than VLC or MPLAYER on this :-)

What exactly do you mean with "full res" ? Imagine a 3'000 x 2'000 video, how to get "full res" ?

But other related idea: add option "Don't ZOOM up video if too small" - so if smaller than 640x480 (full) or cca 620x390 (unfull) then show it 1:1 centered in the area ;-)

I haven't tested 0.44 yet (untested mirror again) ... but I will :hungry:

I have updated it according last version, but any revision/update is welcome.

This is mainly thanks to UPX option "--ultra-brute". But maybe the removal of the fast yuv2rgb, and the fact that the new mmx routine is smaller by 100 bytes contributed also on this.

This mainly mean using a higher resolution or scrolling, but you are right no solution for 3'000x2'000 video.

Yes good idea to disable fitting, specially for small video.

Let me know when preparing next release ;-)

Scrolling would be cool, higher resolution would mean painful mode switch after opening the file and parsing the headers. Or just let the user select manually (as long as available) 640x480 (default) or 800x600 or 1024x768.

No thorough test but seems to work well :-)

DUGL Player 0.4 alpha 3

Post reply

Is there any way to compile this new YUV2RGB16 assembly code into the old DUGL 0.30 which supports MPEG2? I really miss the old .mpeg support! Yes, I know we have MPLAYER, but the (old) support in DUGL was wonderful!

Anyone who can help me out in getting the faster YUV2RGB code into 0.3? Is it even possible?

By the way, is a later version of MPLAYER DGJPP version available anywhere? Latest I have is from 2008!

On DUGL Player 0.30 it was LIBMPEG2 who make the conversion YUV2RGB. So I'm not sure how to reuse the new YUV2RGB16 code as I haven't looked to LIBMPEG2 source code.

> I really miss the old .mpeg support!

I'm not a lawyer but LIBMPEG2 is GPLed lib but not DUGL lib. So I guess that
we need a special license from LIBMPEG2 authors to be able to use it.
Another solution will be to find another not GPLed lib to decode MPEG.

Thanks :-)

Do you have performance problem playing MPEG on DUGL Player 0.3 ?
On my P4 D923 3Ghz, most MPEGs play at not less than 900fps.
