hugin and video stitching

[paisajesenvenezuela]

has any of the hugin creators though about using FFMPEG, OPENCV and
LIBPANO to make user open, read, write video files and to be able to
stitch theM??

VLC is made with QT, and uses FFMPEG, so if any of the coders need
some sample code to work on, they could use VLC and FFMPEG to start..

I would like to see a real-time video stitch/warping program like krpano but not flash based

Well, since all mentioned applications are open source, why don't you
go ahead and start mashing up a nice program? Or do you think this
will be too much work or too hard?
</irony>

I'm not here to discourage anyone, but seriously, this suggestion is
very far from a simple / easy / straightforward task. The availability
of source code "to start with" does not make much difference: being
able to open a video stream and extract frames does not imply that
stitching them automatically (into what?) is done with a few lines of
code. But if you want to give it a shot, go ahead of course.

Oh and by the way, krpano is NOT a video stitching program. It is
"merely" a program which can display panoramic video (ok, warping it
in real time), which is already in panoramic format (e.g. stitched
from multiple videos in a pre-processing step or taken with a
panoramic camera system directly).

I got other project more important, eg: porting software to my elphel spherecam setup

Firstly i stated in the hugin group that im not a programmer, im a lawyer, and im beginning to study QT4...

secondly, before ironically commenting about subjects its better to look in the web....as tom stated, i wrote the thread specifically because in DIY sites there are threads on how to do panoramic video using hugin, with ffmpeg, mencoder and gstreamer...but running the programs dependently..of course you could use some perl scripts available in internet, but the idea is for hugin to do this...

in the DIY there are tutorials on how to do a 360 degree panoramic video with dual fisheye cameras...

on the other hand i mentioned about MPREMAP...written by the author of pano tools..

THIS IS THE SITE..

http://webuser.hs-furtwangen.de/~dersch/mp/MotionPanoramas.html

its written in java and uses ffmpeg and pano tools to do the panoramic video conversions..

also there is ryubins flash panorama dual fish eye sample mode which can stitch video recorded from 2 fishey cameras..but i think flash in hugin is nearly impossible as of now..

the best example is eyesee360's videowarp @ http://www.eyesee360.com/videowarp/, but I would like to see a multi-track version :)

[john doe]

yes but it is paid and only works in mac and windows...as of now ive been succesfully encdoing 3 second 360 degree video using ffmpeg, mencoder, hugin and some perl scripts...

im thinking couldnt it be possible to do a include ffmpeg in hugin, add the program lines to the source files and headers and make the glwindow play the video???you could add a open video function in the menu, and use the glwindow tabs slider to play or seek frames...

hello i found this app which can be used with panotools or libpano13 to make panoramic video..

i only works with video, sound is no suppoerted by the moment, it uses ffmpeg and comes with other video libraries..

from this software i think it is very possible to complete it with MPREMAP or libpano, nona or hugin to to a linux panoramic video stitcher..
