Thanks for the update Darby.

Here's some feedback on version 0.71.
It now works on my Octane2 with V10 Graphics.
Although when executing on the timeline I still get this error :

Code:

[codecinfo] Error:

The downside of this update is that it cannot display a tga sequence ( 1024x576 ) in realtime.
of the 25 fps it can only handle 12 -14 fps. The 720x576 tga sequence plays almost 18-22 fps.
Now I know that this is not a hardware problem since I can play this in realtime with
Blender. ( the software I made the tga animation with )

The resizing of anamorph material ( 720x576 ) to 16x9 ( 1024x576 ) is much better.
There's no decrease in speed anymore ( means that this resizing is done in realtime ) !

I tried to use the cache option and increased it to 512 MB but this didn't seem to make any
difference, still can't play 25 fps.
( this was tested on 720x576 and 1024x576 tga sequences. NON SCALED )

I really hope you succeed in optimizing this code for the SGI cause I really like it

That's my bad; the cache feature is completely broken in 0.7.1. I have a 0.7.2 prerelease package that fixes this; I'll try and put a tardist together.

i installed djv ( specifically djv_0.7.2-pre1-2_i386.deb on a ia32 debian sid chroot running on an ubuntu dapper(64) on x86_64 )
i don't seem to get my preferences saved ( or i cannot find easy where to do that ), so if you can point me to, it'll be nice.

nice features , nice free software, i've used iridas framecycler for quite a long time, and am happy with djv's options.
i cannot get realtime playing (tried sgis and jpgs) if i use the zoom

i just installed it an hour ago, so don't take my reply as nothing more than an ancouragement.
good work!

nice to see one good gpl'ed flipbook software
cheers!

The preferences should save automatically; they are stored in your home directory like:

~/.fltk/djv-0.7.2-pre1/

Could you see if that directory exists and has a couple files like "djv_view.prefs" and "global.prefs"?
(Normally you don't ever need to edit those.)

Can you give me some information about what kind of hardware you're using? Generally zooming in should go faster because there's not as much to draw.

Actually it's BSD; but, it's a fine line.

DJV 0.7.0 was working ok.
Upgraded to 0.7.1 and on starting up djv_view it just dies out and spits :

Code:

XRequest.146: BadValue (integer parameter out of range for operation) 0x32

XRequest.146: GLXBadContext 0x4800003

ERROR GLX Context Bind

I'm on a 400mhz r12k O2, Irix 6.5.22

Going to download and install 0.7.2 and see if that problem is fixed.

No 0.7.2 tardist available yet, so I had to downgrade to 0.7.0
I also get a codec error:

Sorry for the delay; I should have a new version with tardist up in a couple of days. I'll post a message here to let everyone know.

Yeah, that's on my todo list; those messages are coming from the QuickTime library I'm using for UNIX.

As far as I can tell does Blender play the compressed tga's realtime from disk.
When pressing play it play's the files realtime in one go, usually when playing from RAM the first run will be dropping frames.

well, i think it's due to cache size.
i'm playing a sequence of sgis, with a total of ~50MB
it seems i need to set the cache on in order to feel it play smoothly.

but if i zoom in , i get a non_smooth playback again ( with 2048 in cache size )
i am running ubuntu gnu/linux on a dual core opteron with 8Gb of RAM.
i run djv in a chrooted debian sid inside that ubuntu

thanks for your time!

I've changed the mouse a bit in the new version:

Left Mouse - Sample a point in the image.
Middle Mouse - Move image.
Right Mouse - Scroll through playback frames.

Maybe I could add:

Ctrl + Middle Mouse - Zoom in.
Ctrl + Middle Mouse - Zoom out.

How does that sound?

Are the sgi files compressed? I may have to look at optimizing my decompression algorithm; kaos is also seeing bad performance with compressed TGA files.

That sounds like a video card/driver issue; are you using the nvidia linux drivers? Does running debian inside of ubuntu affect their performance at all? (I'm not familiar with virtualization...)

Hi Everyone,

Just a bump to let you know I've uploaded a new release, 0.7.2. Lots of changes in this one; hopefully I fixed more than I broke.

Highlights:

* Save movies and images from the viewing application.
* New customizable keyboard shortcuts.
* Expanded file sequence options.

Plus, specific to this thread:

* The new version should be a little more aggressive about choosing a GLX visual; so if you got an error last time about the frame buffer configuration, you might give it another try.
* Compressed Targa and SGI images should be faster at loading.
* You can zoom with the mouse by pressing Ctrl + Middle (zoom in), or Ctrl + Right (zoom out).
* No more cryptic messages from the QuickTime plugin.

Homepage: http://djv.sourceforge.net/
Downloads: http://sourceforge.net/project/showfile ... _id=118244

Any feedback is greatly appreciated.

Thanks, Darby

I grabbed the lastest version (Linux RPM) and it installed just fine. I feed it a number sequence of .RGB file and it read and played them back very nicely.

If you are looking for feedback on what would be nice to see feature wise, I would look toward's Apple Motion software (part of FinalCut Pro), since that seems to be an analogous product. It would be nice to be able to manipulate the image sequence with some 2D effects such as motion blur, fade-in/out, etc. Perhaps they are already there and I just didn't see them.

Lastly, you could very easily (via ffmpeg) export to mp4--although for some reason it's SGI .rgb converter seems broken in the lastest snapshot of the source code.

Anyway, very nice!

Good to hear, thanks. Do you mostly use SGI image files?

I would very much like to add compositing and editing features, the work involved is a bit daunting though...

I'm currently using libquicktime for movie support on IRIX and Linux, but for a number of reasons am thinking about changing that; I'll definitely take a closer look at ffmpeg.

The SGI image file format is pretty well documented, it should be an easy fix?

I hadn't seen libquicktime before. Looks like a nice API. How do I get djv to export my sequence as a quicktime mov? Can I control the compression settings?

Yes. As you said it's simple to code into your project.

The only caveat I was going to mention is that it's a bit slower than my TGA reader (from having to interleave the image data). But as a file format, I do prefer SGI to TGA.

squeen wrote: I hadn't seen libquicktime before. Looks like a nice API.

I'll just say it's not my favorite, and would like to change to something else.

squeen wrote: How do I get djv to export my sequence as a quicktime mov? Can I control the compression settings?

You can create a QuickTime movie either from the command line, or from the viewer:

Command line:

> djv_convert input.1-1000.sgi output.mov

You can select the codec, but there aren't controls yet for fine-tuning compression options:

> djv_convert input.1-1000.sgi output.mov -quicktime_save_codec jpeg

(Note, I haven't tested many of the libquicktime codecs...)

From the viewer, open your file sequence or movie, and select the File->Save menu option. You can change the codec in the preferences dialog, under the Image I/O tab.

Nice QT export. (DJV_view works fine on IRIX as well here.) As for codec, H.264 encoding seems to be supported in libquicktime. My experience with it in FinalCut is that is kicks serious ass--but you'd want to add separate field in the GUI for setting the bit rate (I usually go high for HD ~18-21 MBs)

BTW compositing and simple motion blur is easy, just shove your frames into the OpenGL accumulation buffer.

Even if you only added one other clip "timeline" then it would be very nice for simple video editing--a simple 1-2 sec cross-fade transition between clips would do the trick.

You have in/out mark points, but is there a way to trim at marks?

All-in-all very neat. We have in-house simulation visualization back-end that spits of number RBG images. I've been doing one of the following.

1) coverting first to jpeg and making mp4 using ffmpeg in a script
2) tar'ing up the images, sending them to a Mac, renaming the .rgb to .sgi and bringing them into Apples' Motion and then into FinalCut.

Both are too limited or cumbersome. It'd be nice to have a native IRIX/Linux option. Rewriting FinalCut is impossible, but with a couple of small tweaks, you'd have everything we need! 8-)

That's good news; I've only tried it so far on VPro and O2. Do you mind if I ask what type of GFX you're using?

Unfortunately the open-source H264 code is GPL, and I'm not entirely sure what legal ramifications that has (DJV is BSD licensed). One option I guess would be for me to supply a package that linked with the user's version of libquicktime, which they could then install with the X264 code.

Do you use any titling for your videos? Or simple compositing, like adding a logo?

It's been awhile since I've used a video-editing app, do you mean adjust the in/out points after they are set?

I tried a Tzero with V12. I can also try an Onyx with IR4.

You could just try dlopen() of the quicktime lib and mapping the functions it uses. If it fails, report to the user that it can't find libquicktime and then wash your hands of it.

Yes titles are very nice, but that means AA fonts and fades etc. Right now I plan to add it to our backend and bake them in the video.

I just meant that once I have the video loaded into djv_view, can I select a section for cut-and-paste (or just cut) somehow.

I was just curious; if it's useful to run it on the Onyx that would be cool to know it works, but otherwise don't worry about it.

That's basically what I'm doing now, but I have the libquicktime API wrapped in my own plugin which I then dlopen. I currently bundle libquicktime (and most of the other libraries I use) with my packages because I'm worried about incompatibilities between shared objects; I got burned on a previous release where my GCC compiled binaries would dump core when trying to load a MipsPro binary.

squeen wrote: I just meant that once I have the video loaded into djv_view, can I select a section for cut-and-paste (or just cut) somehow.

There's no general cut and paste yet, but if you mark in/out points the save function will use them when exporting a movie.

Hi Darby,

Have been extremely busy but I finally found the time to try your latest release.

I tried the 0.7.2 version and its great !!!!
It plays back compressed targa sequences in real time ( 720 x 576 - 25 fps ) even when scaled up to 16x9 .... !)

This is better then the performance I get with Blender or even shake ........

Your the Man !

I can feel it, my mind is going ....
