you're very welcome! the frei0r-dev mailinglist is alive and kicking

i can anticipate you that some filters are "dangerous" and some people
already mantain white/black listing in their own application.

rotate is already implemented in the soc libavfilter repo, I'm
focusing on other stuff so I never tried to cleanup/post that filter
to ffmpeg-devel.

Also note that MPlayer filters are from libmpcodecs which is a
completely distinct thing from libavfilter (libmpcodecs was considered
as filtering API for FFmpeg before libavfilter design and
rejected). Ports of the MPlayer filters to libavfilter are welcome of
course!

I already started an implementation of a frei0r wrapper, and I
discovered some crashes in frei0r plugins so I'll likely contact them.

Thanks for the good hints, regards.

That's great job, Stefano! I heavily use FFmpeg recent days. Last night
I used FFmpeg and avfilter to import movies from my iPhone with 180
rotation. (BTW, why current FFmpeg does not include vf_rotate, while
MPlayer does?)

Sounds really great.

Unfortunately recent days the development of EffecTV is almost stop because
I'm now working on completely different project. EffecTV involved various
people but it seems that all of them are working busy on their own project.
It would be difficult to find a person who can port EffecTV to libavfilter
from this community.

As Niels commented, however, frei0r is actively maintained now and many
EffecTV's filters are already ported. Adding frei0r support to libavfilter
probably works interestingly. Please consider to contact with the community
of frei0r.

Thanks,

Kentaro Fukuchi

Hi,

try this patch:
http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/116243

update your ffmpeg, apply the patch and configure with:
configure --enable-frei0r

then try for example:
ffplay slow.flv -vf frei0r=/usr/lib/frei0r-1/rgbparade.so

I should also be able to easily add frei0r sources.

Have fun!

Interesting, I should be able to write a frei0r wrapper for
libavfilter.

Hi, just to add to your list of projects,
I think most of EffecTV's filters have already been ported to
minimalistic frei0r
and quite a bunch of other developers have been contributing frei0r effects,
http://git.dyne.org/index.cgi?url=frei0r/tree/.

Thanks Jun,

I'm quite sure I can find useful code in your project, but this adds
to the list of projects from which I can grab code, where I actually
need more contributors for adding/porting more filters and extending
the framework.

Regards.



Hi Stefano,

I am an EffecTV developer and used to be the project leader of MAlib
development. MAlib is a C library that can handle a sequence of video
frames, and also it supports filter chaining like your libavfilter:
http://www.malib.net/

Unfortunately MAlib development has been stopped, and currently no one
is maintaining its code. Since MAlib development and EffecTV development
emerged simultaneously in early 2000, Kentaro, the main developer of
EffecTV, and I had a lot of influence on each other. So MAlib team
contributed some part of our code to EffecTV, and vice versa.

I would be happy if some code fragments of MAlib can be of some help
to your development.

Best regards,
Jun Iio, Ph.D.

Hi all,

I'm an FFmpeg developer, and since more than two years I'm working on
and maintaining the FFmpeg libavfilter library:
http://ffmpeg.org/libavfilter.html

Effectv was one of the main sources of inspiration for my work on this
library, and porting the effectv filters to it has always been one of
my hidden dreams.

So my proposal: I want you to be aware of libavfilter and of the
possibility to port some of your filters to libavfilter.

libavfilter has been designed in order to be fast, so should be able,
in conjuction with the v4l2/v4l input device, to render the various
effects in real time. You may also benefit from the abundant generic
utilities and high quality DSP code already implemented in FFmpeg in
order to achieve even more astonishing effects.

Also libavfilter natively supports filters chaining (no need for loop
module), and will be able to perform transmedia filtering (audio
support will be integrated soon). It still lacks some way to manage
interactively user controls but that's something which will be
eventually implemented.

And of course libavfilter allows to process not only the camera input
but each file and input device supported by FFmpeg.

It would be great if someone of you may consider to port some of your
effects to FFmpeg, I'll try to assist as best as I can in this process
on the ffmpeg-devel mailing list.

Best regards.

Hello all,

Thank you for your interests, Tristan.

Just as a quick hack, while V4L2 direct support is not provided officially,
you can use v4l1compat.so to use EffecTV with V4L2 driver. Type

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so effectv

The answer to your question, the project is dead?, is simpley no, but it's
sleeping now. The difference between death and sleep is that still I'm using
EffecTV with the quick hack above, but no official progress is published.

I also want to release Full HD capable version of EffecTV, but still under
slow development.

Kentaro



Ok,

good news, so!

i already tried to get it work with vloopback + "invert" example + PS3
Eye webcam (goooood piece of hardware), but unfortunately vloopback
seems not to deal easily with the YUYV palette of the PS3 eye.
So i tried to hack the invert example given with vloopback, and just add
the fmt=PALETTE_YUYV possibility to it, image is better but colors
inverted...

Will dig that...

Adding V4l2 support for Effectv would be the best, though!

Ok, since the project is not dead, i wish to implement a simple blur
effectv that i could control either with fake keypress or with a hook to
a python script.

Any ideas how to achieve that? i had a look on the code for most of the
effects, but i really dunno where to begin...

Any help or advices would be appreciated

Tristan





Hi Tristan,

We are not dead, but the project not been progressing as most of the
interested parties seem to have moved on.  Someone was going to work
on direct V4L2 support, but I guess it didn't happen.  I'll look into
it when I get a chance.

I did get a V4L2 hook into it using video loopback and some code I found at
http://www.swift-tools.net/Flashcam/ and got a USB webcam to work.

Hi all,

i was using effectv some years ago, and now i need it for a project. it
seems dead, does not support v4l2...

is there a way to get it to work?

it fails with this message:
v4lopen:VIDIOCGCHAN: Invalid argument
Video initialization failed.

While using a simple USB webcam

Thanks for your answers

Tristan





I previously tried contacting one of the PiDiP developers about
this<http://forum.doom9.org/showthread.php?t=130897>but didn't get a
reply. I also posted on a couple Avisynth forums, and this
should be possible with Avisynth. I'm finally getting around to doing this,
but I'd rather do it on GNU/Linux than on Windows if that's possible just
because it's easier, more reliable, &c. Do you know how I could do this on
GNU/Linux? Thanks

Thomas Levine

Hi everybody,

I wanted to know if anybody may started a V4l2 porting of EffecTV, since I'm
actually thinking about it. Anybody experienced may have interests in
helping?

Greets from France,

Christophe

    It would be nice if you could redirect the effected video to another
device (/dev/video2, for instance) so we could use it in other programs like
instant messengers.

   Thanks,
   Danilo Luvizotto

Hello! :)

I've noticed that around 2002 gstreamer stated to include some effectv
effects. I can't find any other reference to these anywhere after that, and
even if they got to gstreamer0.10. I'd like to know if any updates are
planned for effectv or if it's development has been abandoned. I was
thinking in using the effects code to build an application alike Photo Booth
from Apple. I have some C programming knowledge, although this is way ahead
from what I know, so I'd use this as a learning experience too. Is this such
a stupid idea?

I've noticed this won't work with v4l2, will you ever add support for it?

Cheers,

Bruno Santos

Dear EffectTV developers,

My name is Stéphane Ludwig, I'm french and I'm actually finishing my 
studies by doing a Master "Free and Open-Source engineering" in Calais 
(France).

During this Master, we have to participate to a community project. I'm 
working for Open-Wengo (www.openwengo.org), a free and open-source 
softphone with video capabilities. The aim of my project is to provide 
effects on the video coming from a webcam.

The most advanced video effects program is EffectTV and we would like to 
reuse it. The onliest problem is that the Wengophone use it's own webcam 
wrapper, to be compatible with Windows, Mac and Linux.

Can someone help me to adapt EffectTV on the Wengophone ?

Cheers

Stéphane Ludwig

This compile-time bus was introduced by recent glibc and gcc, who had its own
"trunc()" function.

A better way to avoid this bug is renaming them to, say "itrunc()".
A patch follows.

Hi everybody!

Today i tried to compile effectv on my slackware 11.0 and it failed :

gcc -DUSE_NASM -DUSE_MMX -DUSE_VLOOPBACK -DVLOOPBACK_VERSION=91 -DDEFA
DEVICE=\""/dev/video0"\" -DI686 -march=pentiumpro -O3 -fomit-frame-poi
oll-loops -Iv4lutils `sdl-config --cflags` -Wall -c -o utils.o utils.c
utils.c:30: error: conflicting types for 'trunc'
utils.c:30: error: conflicting types for 'trunc'
make[1]: *** [utils.o] Error 1
make[1]: Leaving directory `/home/sx/src/effectv-0.3.11'
make: *** [all-recursive] Error 2


I changed the function trunc to :

/*
 * HSI color system utilities
 */
static double trunc(double f)
{
	double i;
	i= f;
	if(i<0)i=0;
	if(i>255)i=255;
	return i;
}

And it works now... But actually i started learning c 3 month ago so i
don't even know what i did but if it can help ...

I use gcc 3.4.6.

Anyway, thank you for this amazing software !
