I am using the following command to create a video of a bunch of jpeg files. The problem is that some of the jpegs are portrait and others are landscape. Ffmpeg is stretching the portrait images. Is it possible to maintain aspect ratio of the jpegs... perhaps put black bars on the portrait images using ffmpeg?
ffmpeg -r .75 -f image2 -i Image%d.jpg output.mp4
Given a matrix with 0,1 entries, how can I create a graphic in linux such that we have a black square or pixel if the entry is one and white otherwise?
For example, if the matrix is:
0001000
0011100
0111110
0000000
then I want a graphic that looks like:

I will be working with many large matrices, e.g. 1000x1000, or 5000x1000 so I need to do this automatically.
I have been tasked with the job of finding a way to create a video chat application on Linux to use with our health software. We are basically just wanting to add a video / audio component to the system. I have been using Ubuntu a long time and have decided to use it as our platform for the new software. We currently use Emblaze VCON with our software on Windows and I want to eliminate the need for Windows completely. We supply the hardware so if I can get good quality video chat integrated into our software then I am all set.
I have been playing with some apps like vlc, cheese and luvcview. I am quite impressed with the video quality I am getting so I know Linux can give our users a great chat experience. I even tried Skype 2.0 beta and that worked great too.
I see the software working just like Yahoo or MSN does. I provide a list of users and whether they are online and when you double click on their name they get a ring and prompt to accept the incoming call from "Joe". If there is an engine already in place that we are free to use and bundle with our paid product then that would be great. I am really ignorant on GPL licensing so I want to be careful on what we do. Also, I think this method is best for the connection... I like the idea of a server which receives input from all clients and tracks their online status but when you make a call to the other person it communicates p2p style to minimize hops and server load. We will be controlling the firewalls on the hardware but not what this hardware may be behind, ie. Router - so I guess I need something that can tunnel through / around such obstacles.
I would really appreciate if someone could point me in the right direction on what I could use to do this and also not have to worry about licensing and Intellectual property violations. Btw, I don't see the need to modify the software if it can handle the p2p chat out of box and do it well. I will write the components to handle online / offline status if the "engine" doesn't handle this.
Having trouble handling JPEG-2000 files. Message says I need some plugin. I've checked in Synaptic and there are a couple of packages installed by default that mention JPEG 2000 but obviously I need something else. Any ideas?
View 3 Replies View RelatedWhat would be a nice, simple command to go through all files in a directory (no sub-directories), and change all the MP4 Video files I have to MP3 audio files (keeping the original filenames except for changing the "mp4" extension to "mp3")?
The files in question were videos taken with one of those Flip cameras, but I only need the audio off of it.
I have a mp3 file and would like to convert for video, the jpg will be the image of the video.
View 6 Replies View RelatedI have a very big image directory: One image per minute, whole a year, captured from a webcam. Now I want to make a video (15 or 24FPS) with all the webcam captures, to see how it changed during this period. I've tried automotion, but it makes a very low quality video, besides it blocks with lots of images. I've also tried dvd-slideshow, but it's not possible to make a more-than-1FPS video.
I also need to change the date in each webcam's images, because they are wrong, so it needed to overlay a little layout with the right date for each image, is that possible to manage within some application? Preferibly shell applications which supports lots of Gb of information (anyway I always could make little videos and then glue them)
Does anyone have a solution that actually works for creating video DVDs from beginning to end? My requirements are pretty simple, I would think. I need to take video from an NTSC DVD (which I made from 8mm analog tape), edit it, create a menu, and burn it. It doesn't have to be fancy. It just has to work. The total project is a little over 1 hour of video. I have reasonable computer power for this.
That doesn't seem like such a difficult task, but it actually requires using up to four different mutually incompatible programs, each of which has nearly infinite options, a huge number of intermediate file types, and infinite ways to fail. If there are intermediate files to be written, I need to know EXACTLY what files and formats to use, and what packages must be installed to use those formats. I don't care if the programs are KDE or Gnome (even a command line might work if the procedure is clear-cut).
The task consists of four parts:
* Rip or import an ordinary video from DVD. (This was made by a hardware DVD recorder).
* Edit videos. Create clips, cut, past, move, fade.

View 2 Replies View RelatedMy 1st and only grandson turned 1 year old and we have taken about 1 million pics of him. I wanted to make a video from pictures taken in the past year. The first one is an ultra sound picture. The last one was taken this last Saturday. I have 153 12 MPixel pictures in a folder. They are named C001.jpg - C153.jpg (I can rename them if needed).
I had noticed mencoder or ffmpeg can create movies from jpegs. But, I didn't think about the frames per second. Would I need to make like 20 copies of each picture and then make it like 10 FPS? or something like that? Optimally, I would like to have a video where each picture lasts for 8-10 seconds or so and I would be able to add a song as audio. (I think I know how to use mencoder to add the audio).
I need a way to create wmv video thumbnails with file information (name, size, resolution, duration) using Ubuntu.

View 7 Replies View Relatedmost canon selphy printers does not work under linux, but i think its possible to send files to a selphy printer via bluetooth. and after recieving the file, it instantly prints the image. my question is, is there a way to send files from a pc to selphy via usb instead of bluetooth. i believe you can use obexftp to send files from pc->selphy and it will instantly print, the problem with this approach is that it takes a lot of time to send the file. if there is a way to use a cable to transfer the files then we could print directly. or is there a cable that somewhat simulates how bluetooth transfers.
View 1 Replies View RelatedI met a guy who is going about with a thermal imaging device. He wants to remove the watermark from the images and tells me that the software developed by the company can do this using only the jpeg. Unfortunately it's only available for windows. I'm dubious that this is possible, but I have to admit I'm not extremely well versed in image manipulation. Is it possible to extract the unadulterated image from a copy with the watermark and other data on it?

This happens on a system running 10.04 / 64-bit. As I seem to recall a recent gimp update (might be wrong), I checked a 32-bit 10.04 laptop and it does not show the behavior. For information: the 64-bit system has some additional stuff installed for image processing (ufraw and darktable) but I have been using this already for a while without issues. The other main change on this 64-bit system before I noticed the problem was the installation of a geforce 8400 video card including the 'nomodeset' option in grub and install of the latest driver from the nvidia website. verify that the gimp on a 64-bit system is still functioning.Further a 'repair' from within synaptic throws the following error
Code:
E: /var/cache/apt/archives/gimp_2.6.8-2ubuntu1.2_amd64.deb: subprocess dpkg-deb --fsys-tarfile returned error exit status 2
Note: I found some messages regarding this problem on the web but they were referring to older kernels (2.6.8); and people reverted back to an even older kernel. And yes, there have been a recent kernel upgrade.
I use GIMP to edit pictures. When I cut part of one picture and put onto another picture, I try to save it as a jpeg, but it says "You must export image before you can save- JPEG Plug-In can't handle transparency." Is there another plug in that allows me to do this?
Also on a GIMP related subject, how can I set the eraser tool to transparency instead of white/other colors?
Any recommendations, the only thing I can find is inkscape, gimp doesn't seem to offer that facility.
View 4 Replies View RelatedI received a popcorn hour set top box for Xmas, and I am trying to figure out the best way to convert my extensive DVD collection to MKV files to play on the PCH.
I know I could just create an ISO of the DVD, but that would take up 4-8 gig per movie, where from what I've read, MKV offers GREAT audio and video quality at a fraction of the space.
Is there any software packages out there for linux that would allow me to rip my DVD's to MKV? if so, will they allow me to just rip the movie part of the disc, and not the extra's or menu?
Is there any easy-to-use program for ubuntu like handbrake or autogk for windows?
Or which software do you think is the best for creating avi or mkv files on linux?
I have tried a few methods and have not been able to burn a dvd yet. I can create the files that would go on the dvd. I first created a slide show using OpenShot. I saved it as a avi. First off, is this the correct format? Also, I have other files from other methods that end in .mov. Is this the correct format?
Can I combine the two formats of .avi and .mov on the same dvd ( have not even gotten to this point yet, but figured I might as well ask up front )? To burn the dvd, I tried qdvdauthor. It crashed on me after I autogrouped two files. Also, I tried k3b and DeVeDe. I was able to create files, but I still could not get them onto a dvd. I tried to take the files from k3b and DeVeDe and create a DVD in Brasero. Brasero just closes. No error, no success message.
How do I get files on a dvd in Ubuntu? I would even be happy with tutorials or links of software that was worked. Also, I will don't know how to get an audio cd burned in Ubuntu yet.
I'm trying to create a DVD with K3b, I encoded a DIVx MP4 file to vob, but i need to create the iFO and BUP files if that is correct? is it possible in any way to create iFO & BUP files?

I have a Samsung BD-6800 blu-ray player that i want to stream HD mkv files to from my pc. I made sure DLNA was enabled in the /etc/ushare.conf file. The blu-ray player sees my pc perfectly and i can navigate to the folders where the videos are stored, however when i select a folder with videos in it all that is shown is an option called "upper folder" which takes me back to the root directory. The videos are nowhere to be found. I checked on the Ushare web site to see if mkv files are supported which they are.
Here is what my /etc/ushare.conf looks like.

# /etc/ushare.conf
# Edit this file with 'dpkg-reconfigure ushare'
# Configuration file for uShare
# uShare UPnP Friendly Name (default is 'uShare').
