Hardware :: Simultaneously Do Video Compression Whilst Playing Back 1080p?
May 27, 2010
I wanting to build a media player/PVR MythTV linux PC for my TV which will be capable of simultaneously encoding video(both h.264/MPEG-4 and xvid) whilst playing back 1080p video. That way I can watch hd video I've recorded whilst I'm recording and converting another programme in the background.
Hauppauge HVR-4000HD - Video Capture + DVB-S2 receiver
Shuttle XPC SG45H7 - Barebone with built-in Intel GMA X4500HD Graphics
Intel Core 2 DUO E6500 2.93GHZ
2GB RAM
...And if not, what do I need? Would a quad core CPU be a safer bet, or is that overkill?

I have a Dell laptop and have multi-media buttons, some of which control the audio volume. But once a game is running like Sauerbraten, I cannot control the volume. The controls within the game are relative to the master volume, so if the volume is too low, I have to exit the game to adjust it.

I know Ubuntu has limited flash support but how else do I view a high definition 1080p video? Its all choppy to say the least, after a few seconds, its just like a slide show. I am using flashplugin-installer from adobe to render flash files.

What software(exceping drivers) do you need for maximum performance with blu-ray movies or .mkv files? Is there any place I can find linux codecs or video players? I'm using Slackware64 13.37

I use Ubuntu 10.04. I need to play a full HD (1080p) video on my pc:
CPU: AMD Athlon X2 7750 BE
MB: ASUS M3A32-MVP
RAM: 2x1GB KINGSTON 1066MHz
VGA: ASUS 8800GS
I think my PC should be able to play it, but the video is really not fluent. What should be wrong? Power less hardware? Wrong codecs?

When I watch a HD movie, the video will freeze momentarily sometimes. Would a 8400GS or 9600GT take care of this?
My video card is a 7300 le,
CPU= Phenom 8450
Memory= 4gb PC2-6400
Power= OCZ Fatal1ty OCZ550FTY 550W

I have a Zotac IONITX-F-E motherboard (Intel Atom Dual Core 1.6 GHz + Nvidia ION) -based box with Ubuntu 10.04 64-bit installed. Do you or does someone you know have the same setup as I do? If so, do they have 1080p video playback working? If so, what driver are they using? I've tried following every guide I could find, but no luck so far. I have libvdpau1 and libvdpau-dev installed. I have the nvidia 195.36.24 driver installed (I used the nvidia installer). I have mplayer installed (which I compiled from source with --enable-vdpau).
I try to run mplayer with this command:
Code:
mplayer -vo vdpau -vc ffh264vdpau path/to/myfile.mkv
I get the following message in my terminal:
Code:
Error opening/initializing the selected video_out (-vo) device.
I have libvdpau-dev and libvdpau1 installed.
After Googling this problem, I found a post that suggested the following steps:
Code:
sudo add-apt-repository ppa:nvidia-vdpau
sudo apt-get update
sudo apt-get install nvidia-glx-195 nvidia-195-modaliases
It turns out that I had already added the nvidia-vdpau repository. However, despite that, I get:
Code:
E: Couldn't find package nvidia-glx-195
The same problem exists for the nvidia-195-modaliases package. Do these packages exist? Is there some other way to get them?

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?

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.

I have onboard video card (GeForce 6150SE nForce 430) and I install one PCI-E video card (GeForce 7300 GT). In BIOS I set primary video cart to onboard. Is it possible to work simultaneously? lspci -v command showing both, but nvida-setting, nvidia-xconfig and system-config-display only show one, never both.

I rip the DVDs that I own to my hard disk using a straight-up 1:1 copy, ie to an ISO image. This works great usually, but for this specific DVD that I'm presently trying to rip, I'm being told that the DVD is literally 64GB in size. It's definitely not a BluRay disc, and I don't even have a BluRay drive, so that possibility is ruled out.
I'm not having any problems playing back the DVD file in VLC. I'm running Ubuntu 10.04 64bit. How on earth could it be a 64GB DVD?!? Isn't the max capacity of a DVD around 8 gigabytes? I don't even think that BluRay discs hold 64GB of data!

I know that this laptop (Asus UL30A) does support playing HD material with the help of the GPU on windows. The question is how can I do this under linux? The CPU load as is implies that this is not activated. I assume that it's limited to a handful of codecs. But which player supports this, if its even supported at all?

plain and simple how do I watch my old .amv videos. Whenever I try I get this error.
Quote:
Could not display "/home/derek/Videos/shrek 3 (Ipod).amv". There is no application installed for RIFF audio files
I have no clue whats so ever how to get around the error. I installed the medibuntu though terminal sense that was restricted codec I thought but nothing.

Recently, I noticed that I can no longer see any video when playing m4v files (audio is OK). These files worked fine until recently, and the problem persists across mplayer, totem, banshee and even firefox.
I am running Natty with the 2.6.39 kernel.

I'm on Fedora 13 GNOME. I haven't installed proprietary Nvidia drivers for my GTS 250 graphic card. The problem is now whenever I play any video file in any video player the PC freezes locking up virtual terminals. However the sound of the video continues to play on until the video ends. I have to then cold reset from the switch on chassis. What can be the probable reason behind this?

When i try to play HD (even with 720p) video the CPU load is almost 100%. I'm using vlc player and the movie is barely watchable. If i switch to Movie Player, the CPU load is slightly decreased, but after 2-3 minutes the audio goes out of sync, so no solution there. I have an nvidia 8600gt graphics card and the proper driver installed, every compiz effect works flawlessly without the slightest increase in CPU load and a dual core 2,1 GHz AMD processor. It shouldn't be a hardware issue.

I have a Core 2 Duo T9600. I noticed video playing performance has been really bad lately, and videos that used to work fine now stuttered. I would say it started happening 2-3 weeks ago. I discovered the culprit is that the CPU is scaling down to 800Mhz and sticking there. Running cpufreq-info yields:

I've been using Ubuntu 10.04 for about a month and generally the graphics work fine (I have a Radeon 2600 XT graphics card and have installed Catalyst Control Centre 10.7).3D games such as Nexuiz work fine and I can generally play different types of video but when I try to play HD video it gets pretty jerky. The same files play fine in windows so I'm guessing it's a software/driver issue. I've read various related posts to this and after typing 'top' into the terminal, I can see that playing the video takes most of the CPU processing resource up, which I as I understand, suggests that most of the work is not being offloaded to the GPU.

I am trying to burn a video DVD created from "Devede" with K3B. The video DVD successfully burns, and plays in my computer, but does not play in any of the DVD players in the house. I used to user "ConvertXToDVD" when I was on Windows, but am trying to find a free/open source alternative on ubuntu. I am using all default options. I have looked in the settings for both programs, and I fail to see the problem here. Even the ISO created from devede seems to match up to the Video DVD (that works in the players) I had burned with ConvertXToDVD.
In Devede I have it so that the menu is disabled and it automatically plays the first title. Apparently this is not good enough.. I thought this program was supposed to be easy to use? What am I doing wrong here? I am using the same DVD-R I have used before on my Windows machine to great success. I am getting frustrated as I have went through 2 DVDs,
