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.
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?
As far as I can tell, I have all the applicable applications and plugins (for this, Debian 5.0.6 installation). I type in Code:about:plugins in either iceweasel or epiphany browser and get a list that includes:
Code: Installed plugins Find more information about browser plugins at mozilla.org.
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.
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.
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.
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:
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.
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 :
"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?
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
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 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.
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 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'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.
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).
Is it possible to prevent "unable to connect" messages from appearing instead of blocked web-content? I am using a huge hosts file to block unwanted web content from appearing. The attachment illustrates what I am referring to.
How do you set the MTU on the network card for Jumbo Frames? The MTU drop drown only goes to 1500 which is far from the Jumbo frame rate of 9000. If I type 9000 in will it blow anything up?
Recently due to partitioning and a power failure Ive had to now copy all my backup movies etc. back onto ubuntu as they are corrupted. At the moment the thumbnails of the movies are the generic orange media image and when I replace it with the backup movie, across to ubuntu and refresh the browser, the thumbnail stays the same i.e. it doesn't show a small screen cap of the movie. Is there a way to 'refresh' them properly as it were? I am running Ubuntu 10.10.
i have just installed ubuntu 11.04.The thing is my screen is flickering but i cant find how o set my refresh rate o 75Hz to stop it.In the monitors panel it says monitor is unknown and i can only set the refresh rate as 50,51 and 52 Hz. how to set it to 75
I'm running Natty on an Nvidia 8200 chipset. I found how to change the grub/tty resolution here, but anything I run from tty takes about a full second to redraw the screen. I KNOW this is something simple, but I must be missing it.
I just did a fresh install of natty on my desktop and at first I had a box bouncing around my screen saying input not supported. I changed my refresh rate from 50 to 52 and it got rid of it, but I still have the bouncing box on the login screen. How can I adjust the refresh rate for that?
This morning I was looking around and went to the display settings and such. And I noticed refresh rate was at 75Hz. I changed it to 85Hz and the screen went black. I tryed to reboot but after I got passed the Login the screen went black again. Now I want to change it back to 75Hz because the monitor wont allow it. How do I change it back to 75Hz from the login screen?
I was wondering if it was possible to play .bin/.cue movies. I was able to do it with daemon tools in windows and acetoneiso doesn't seem to like the file format. I was led to bchunk but the isos it made seem to be corrupt. Any way to play these movies?
