General :: Join Two Video Frames Into One So The Final Video Plays Two Frames As One Simultaneously
Oct 11, 2010
i want to connect two videos into one. let's take two videos from videos as an example. i want my final video to have the height = height of first video + height of second video and width = max(width of first video, width of second video). in the upper part the first video is played whereas in the lower part the second video is played.
do you know how to do it under linux, the best possibility while using mencoder, ffmpeg or any other command line command?

I'd like to edit a few frames from some videos, and then return them to the video stream for playback. What are the best tools to do this with?
I tried exporting a frame with Kino, editing with GIMP, and then re-inserting it into Kino, but Kino rejected the attempt.
Will Kino do this, or do I need to be using something else?

I have Ubuntu 11.04 on a Dell Studio XPS 1640 with ATI graphics and the fglrx driver. It's a powerful machine and I've had no problem what so ever to watch full hd videos on windows 7 but all videos, no matter the resolution, has a very small stutter which is annoying but not making the videos unviewable. But I'd prefer not having it at all. I have tried setting the VLC video output to x11 but there is no difference. It's a screen tearing problem, that was fixed by setting the option "Tear Free" on in ATI Catalyst Control Center.

I just installed Lucid Lynx RC 1 on my MSI Wind U100 netbook. When I tried to play a video on it I was informed of a lack of codecs, so I downloaded my video player of choice: VLC media player. When I tried to play the video, there was audio but the screen was black. The same thing happened when I downloaded to codecs and used the stock video application.

Way back from Windows 3.x days to the latest 64bit Windows 7 (classic/standard theme)there is a way to make the window edge border wider then 1 pixel.I often use 3 to 5 pixel to make it easy to grab on hi-resolutions displays and hi DPI monitors.There doesn't seem to be an easy or obvious way to do this with the Gnome X-Windowing system?

I am experiencing a problem with viewing 1080p movies. The frames get stuck and don't refresh, so I am left with a single image while the sound plays on fine. I find that this only occurs with high resolution movies, but I am curious as to where the problem lies and if I can fix this at all. Here are my computer's specs and configurations:
I am using Ubuntu 10.10 (didn't want to get 11.04) with 2GB or ram and 972.6MB of swap (I need to increase that to 4GB, I think? Correct me if I am wrong). I am using a Toshiba u400 Satellite which comes with a Intel X3100 Integrated Graphics chipset (don't really know the strength of this set up) and has two 1.73 GHz processors. The only thing that is within my power to change is the swap allocation. When I start the movie and bring up the System Monitor, VLC takes up almost the entire CPU usage.

Since I installed Ubuntu 9.10 recently and downloaded a new copy of MPlayer, a Shell execution of Mplayer of a video with the -fps switch, sees the -fps being ignored. The video in question plays the video too fast and goes out of synch with the audio. This has never been a problem as I play the video using the shell and include the -fps option to slow the video down. For instance, the command below would play the video at 30 fps:
mplayer -x 640 -y 480 -fps 30 "/media/USB2/williams.flv"
It has always worked before. What's changed in the latest mplayer, or is there something else I need to install in order to get -fps functionality? I can paste the (rather long) output mplayer gives upon execution of the above command.

Why would the frames and buttons disappear after a regular update. I rebooted which took back the buttons I was missing from the top=right corner of the windows but, the frames are still missing? I am using a combination of Compiz and Metacity and until now all has been working really well. I don't even have the awful window resize delay I was having.

Compiz was installed and working when I installed the 'new' ubuntu. (x86-64) What I did:installed my nvidia driver, enabled secondary screen (twinview) Installed some extra compiz plugins using aptitude. Tried to enable the desktop cube, and with that automatically disabling the desktop cube. And bang, no more window frames.. I tried with GTK window decorator and with emerald. It doesn't make any difference. Now I am running meta-city and emerald without any desktop effects.

With Mellanox 10G NICs and the MTUs set from 1600 to 9000 we have tcp sessions hanging. Executing ls during an sftp session just hangs. The same thing happens for an ssh session, if execute ls I might get few item in the directory but then the session hangs. Like wise for FTP. The Fujitsu switch is configured by default to handle jumbo frames. At 1500 MTU everything works fine. We are running the 2.6.25.14 kernel with CentOS 5.2 and the Mellanox driver.

I have UDP packets generated on Machine A that are addressed to Machine B (unicast) that I capture with PCAP. After transporting this raw data to Machine B (via RF modem) I'm trying to reinject the original UDP on Machine B through a tap0 interface. The capture and transport are all working fine. BUT once on the destination machine, the reinjected ethernet packets are NOT being received by a local UDP server. this is my socket creation :
Code:
outputSocket = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
struct ifreq s_ifr;
strcpy(s_ifr.ifr_name, "tap0");
"data" is an unsigned char array that contains the original packet data received from pcap, which includes the ethernet header, ip header, udp header, and payload data. after the call to write() completes, Wireshark on Machine B sees a correctly formatted (checksums and all) UDP packet when listening to tap0 - ie. no lines highlighted in red. *BUT* - a UDP server i have running on Machine B never receives the reinjected UDP datagram. (I have verified that this server works, by using a simple local udp generator app.) is there something wrong with how I'm creating the socket and/or writing the data back out to the tap0?

Since I prefer bigger than default size fonts, I am having a problem using iceweasel. Web-pages, especially frames, are not drawn properly with overlapping and hidden text. I am thinking about alternatives that may exist than can replace iceweasel.

I'm getting dropped frames from both Digital8 & MiniDV camcorders using Kino. MyCPU doesn't seem to be spiking. I've made sure compiz is disabled and no memory/cpu hungry apps are running. I'm using SATA drives so DMA shouldn't be the issue.
The video and audio that is captured seems to be fine.

CPU - AMD 64 FX-55 Processor
Mobo - GA-K8NXP-SLI

I wrote an application that receives packets on one interface and sends them to another interface after it added a vlan header. Both the sending and the receiving is done using raw sockets. Everything seems to work fine until I get TCP packets that are of size 1514 (MTU). Once I add a vlan header to the packet, its size becomes 1518 and when I try to send it I get the returned value -1 and errno=90 (message too long). I tried to change the MTU of the NIC to a value that is bigger than 1500 but that fails. If I create a bridge using brctl and vconfig between the NICs I can see that my NIC does sends packets of size 1518. What do I need to in order to make my NIC to send packets of size 1518?

In my graduate professional writing program, I have had to make several documents that integrate graphics. In order to manage the graphics, I taught myself how to use frames. But I discovered that the Openoffice.org word processor has a problem saving the frames correctly. I save my document and close it. When I reopen it later, the graphics in some of the frames (not all) are distorted; they appear cut in half. Examining the frames, I determined that the anchors of the affected frames had changed since I saved and closed. Changing the anchors back to whatever they were restored the graphics to normal. Every time I saved and closed, this happened again. The first solution I came up with was to save with the frames set properly, and export the document as a PDF file; the frame anchor settings will not mess up for that.
Then, because I save my school documents as Word files (the university--that program, anyway--doesn't use Linux), I tried saving the document as an OpenOffice text document (.odt). That also avoided the frame anchor settings problem, meaning the problem occurs only when saving as a Word document. But since my professors probably don't use OpenOffice, I am submitting PDF documents in this situation.

I have downloaded a film from a commercial TV station for my own use and want to edit out all the advertising breaks. I have tried Cinelerra but I cannot find a means of deleting selected frames, I also looked at trying to use Kdenlive but cannot find a way of loading the complete film to work on so unable to tell whether it might be useful.

I was able to build a NFS server and a NFS client using OpenSuse 11.3 and connect them together using gigabit ethernet through a switch. These are the only 2 devices on this net (192.168.1.xx). I tried to set the MTU to 9000 and 9014 but learned that the Realtek 8169/8111 only support up to about 7200 MTU. So I inserted Intel NIC cards on both and set both to 9000. The system accepts this and I can ssh from one machine to the other. Both NFS client and server start w/o issue and the client mounts the device just fine. But when I try to copy a file on the NFS client from the local disk to the server, the client just hangs and I have to physically turn the machine off in order to get it to work. Both systems are using the stock software from the DVD (I didn't update either).

I am looking for a PCI Ethernet adapter which supports jumbo frames. The card I have now - Trendnet TEG_PCITXR - says it supports jumbo frames but it turns out the MTU is 7200 bytes. Yeah this is more than 1500, but it seems like a bit of a scam to me. Since it is nearly impossible to find these specs on product info pages, I was hoping someone could recommend a network card that is proven to support 9000 (or greater) MTU. Some more info, I am running Ubuntu 9.04, kernel 2.6.28-19

I've changed the theme in tweak to 'dust and sand' but I don't get the window frames changing. There's a blue surround that didn't change with the theme change. Also I'm assuming the button layout will revert once the window frames do....Like the gnome3 interface better than unity though.

My current computer has a VGA output on the motherboard and I'm interested in adding a monitor. I have a separate nVidia card which, when installed, seems to default as the primary. Is there any way to have the system use both the VGA on the motherboard and the additional video card? I've seen a lot of suggestions to modify xorg.conf but the file is nowhere to be found on my machine.

My partner is a teacher and has downloaded some videos from a teacher's resource site but can't seem to play them in Ubuntu. They play fine in Windows XP using Windows Media Player but they only play a few seconds in VLC or Totem and then freeze. The files in question seem to be normal MPG (MPEG-1) video files but somehow VLC and Totem choke on them. I have installed all restricted video formats including w32codecs but still no joy. My partner is threatening to go back to Windows!

I was setting up my Totem Movie Player on Ubuntu 9.10 and at first it wouldn't play dvds at all. So, I went online and entered these two commands into the terminal to play restricted dvds.
sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh
DVDs will now play on Totem, but now I don't have any video. I can hear sound and if click around the screen I can get it to play but I still don't have any video. I also tried both dvd drives on my computer and tried different DVDs. Still same thing.
