Ubuntu Multimedia :: Anything That Can Be Done To Increase Video Streaming Performance?
Jan 19, 2010
Is there anything that can be done to increase video streaming performance?The general impression I got is that it's mainly an adobe problem and not much can be done, though currently streaming is nearly unwatchable. When I switch from full screen to normal size many of the players freeze, ..... HD is unwatchable etc.
I have a dual boot on a netbook with windows and fedora13. When I am on my fedora boot and I try to watch streaming video it comes through in waves or not at all. I do not have the same problems on the alternate boot. There are other performance comparisons where the windows boot runs smoother and faster. Is there any work I can do in order to optimise my fedora boot in this capacity?
I have a ubuntu desktop running 9.04 and a Acer Netbook running UNR 9.04.Using NFS I have shared my videos from the desktop and have it automounted at start up on the netbook. I can navigate to the files but once I click play, the netbook locks up.Is this a limitation on my hardware or is there a better way to "stream" these vids?
I would like to stream my HD Movie collection over a wireless network to my PS3 and/or Xbox 360.
All my movie files are MP4s and I wondering if it is possible to do this. If possible, I'd like to use the VLC player to do this but its not too important. I really really really do not want to sacrifice any video or sound quality while streaming.
My local priest has asked me if I can use my computer skills to stream church services live for people who can't make it to church.I said, sure thing! I thought it would be simple, but the deeper I look into it, the more lost I have become!Here's the tech requirements:
- A camera with good optical zoom and focused on the altar (the camera will be stationed at an unobtrusive point at the back of the church on the choir balcony) - Everything must be wireless (power is available on choir balcony to power the camera). - Sound should be synchronised perfectly with the video (have access to the church PA system - located behind altar) - the internet connection should be able to upload the stream to a virtual server (i.e. with root access) that's accessible to the web with ease. What upload speed would I need? Would 256k be enough? HD video is not required - ..... quality would be great. We can upgrade to HD at a later point in time! - What bandwidth requirement would my server need if say 1000 users were connected? Seeing as they would most likely be locals, would just one stream be sent to the local exchange and that exchange would send out the stream to the 1,000 users, or would each user have to have a dedicated connection to the server? - Say I bought a camcorder with HDMI output, what kind of processing power would I need to convert this to compressed video? (I've got an old Pentium 4 and an AMD64 2.0GHz lying idle in my bedroom and it would be great to make use of 'em instead of chucking 'em on the skip) - I'd like all this to be done so that HTML5 browsers can access the video, resorting to flash if necessary - I'd also like to be able to power down all the hardware with ease: i.e. set a timer. I'm sure ubuntu can do this with ease? What about configuring the camera to zoom in every time it is powered on? Can linux control the zoom on a camcorder? - Am I totally nuts?
I've got a NAS mounted on a linux machine, and here at another location, I have my Ubuntu laptop. I'm able to remotely, securely mount the directory my NAS is mounted on in the linux machine onto my laptop via sshfs, giving me remote access to my NAS via my laptop.The problem I'm having is.. even though I have a high downstream at the laptop end, and a hefty 1mb upstream at my home, I still can't quite stream the movies I have stored on it. I can stream them, but there is a lot of stuttering.I've tried messing around w/ various options w/ mplayer, but I can only improve it slightly at best. Am I missing something? Is it a size issue that it comes down to? The files are roughly 700mb for a 1 1/2 - 2 hr avi file.
When I play streaming video on hulu or other sites it is choppy. However, the sound is fine. Video files play fine when I download them.I experience this problem in both Firefox and Chrome. I have a 10MB connection on other Linux desktops the streaming video is fine.I imagine it is a flash issue, but I have the latest flash v10.1.The other solution would be a video downloader for streaming video. I have not found one that works on Linux.
I am elevating this thread up a level from [url] . Ubuntu 9.10 no longer streams without the screen pausing and going black every 2 minutes! Our product was just going into production and now we need to hopefully find a version of Ubuntu that streams video! We couldn't go with Unbuntu 10.04 because the video streaming was 30% slower than 9.10.
I'm not sure this is, strictly speaking, an Ubuntu problem (although it may be), but people around here seem to be more knowledgeable than they are anywhere else, so it's worth a try.
CNN recently started offering its news station on live streaming video for those who get CNN from a participating cable provider. For better or worse, I get CNN on Comcast, so no problem there.
Except for lagging video because lack of processing speed, it all works fine on my netbook, on which I have Ubuntu 10.04 installed.
But on my desktop, where I'm using Ubuntu 11.04, no such luck. The problem is the same regardless of whether I'm using Opera, Firefox or Chrome.
I can go to http://cnn.com/video and get the standard video streams (not CNN live) just fine. When I click on the "Live" button and then the "Unlock Live TV" button, I get, as expected, the "Sign in to watch live TV" dialogue box. So I click on Comcast, log in correctly, and am returned to the main screen. The page appears to be loading correctly, and then I get the "Sign in to watch live TV" dialogue box again. No matter how many times I try, that's what I keep on getting.
If this didn't work on my netbook, I'd just assume that for some reason the setup is Linux-unfriendly, but now I'm determined to get this working.
I've checked my plugin settings on my browsers and nothing seems amiss. I've tried deleting all cookies, persistent storage, Flash cookies and all such things, but to no avail. Even though I had the most recent version, I even uninstalled and reinstalled Flash, but that didn't change anything.
When I watch movies on Ubuntu I noticed that quality of reproduction is not good as in Windows. All movies seems to have some sort of contrast problem which I don't know how to fix. This problem is not present in Windows (XP/7) and stand-alone DVD players play them also correctly.
Here are images (AVI, DivX format)
Windows version: http://i52.tinypic.com/125hlis.png Linux version: http://i56.tinypic.com/tz53t.png
Also here is MKV format which is noticeably even sharper in Windows:

Note: I didn't wanted to include them in post since they are quite big and I didn't want to do JPG compress since they might lose quality. Try not to resize them.
On Ubuntu I installed some 'extra' codecs (might be proprietary) via Software center. I use standard movie player that comes with 10.10, but for MKV I use VLC since mkv don't run in standard movie player. On Windows I use k-lite codec pack and GOM player. My guess is that Windows solve those sharpness and contrast issues by using some playback filters (possibly contained in k-lite codec pack) that are unavailable in Ubuntu. I installed proprietary video driver for ATI RADEON 2600.
I am trying to get video streaming working to my iphone. I have everything working fine using Handbrake to convert to .m4v. I takes a 2.2gig and compresses it down to about 550 megs. Then I am just posting a link to a web page for now for the iphone to open.
It all works but after about 4 - 5 mins of video it needs to buffer. Is there anything I can do when encoding them to help? or is there some kind of video staging server that can be used?
I've recently found a Dell Optiplex GX110 - about 10 years old with a Pentium III. I installed Ubuntu 10.04 no problems, and it behaves quite well, despite its age.However, if I try and stream video from web sites (....., bbc etc), the result is underwhelming - very jumpy images, although sound is fine. Interestingly, viewing video files through VLC does not have such an issue - it seems to be OK - it is just http streaming (typically Flash) where I observed the issue.I found an old graphics card - a ATI Radeon 7000 and installed it. However, I saw no improvement in streaming video performance. I was a little surprised, but would like to understand the reason - is it:the card is so low spec it would not make a difference, or is it that:the card *ought* to make a difference, but is not configured and/or performing correctlyNote that Ubuntu appears to correctly find the card - lspci shows it correctly identified.
I am trying to set up a video streaming server on my Gnu/Linux Ubuntu 10.10. I want to be able to stream videos that I have on my computer to my friends who aren't on my network.streaming audio applications but that won't help me. Most of the tools available are only for sharing within your own network.
I'm using an Ubuntu desktop box as a home server and I want to be able to stream videos across the network to my Android devices wirelessly, however a plain UPNP server will not do, I also want to be able to password protect the streaming server so that only I will be able to view the videos without anyone else in the network being able to see my personal video library, is there any way I can do something like that?The devices in question are a Google Nexus One running Android 2.3.3 and a Motorola Xoom running Android 3.0.1.
i have some issues running twinview through my laptop and an additional monitor. i currently have the nvidia settings such that the monitor is the primary screen. however, whenever i click full screen in videos or another application, it maximizes in my laptop screen. also - when i maximize videos videos, the screen fills up, but the actual video size doesn't tend to increase (it doesn't stretch to fit). is this an adobe problem? ubuntu 10.04, nvidia driver v195, dell latitude d630 laptop.

ok i upgraded to 10.04 lucid and now if i want to stream audio i get jerky audio with screen flickers and video streaming or not causes a complete lockup of the application. this all worked fine with 9.10.
I've been interested in trying to figure out how to do some real-time transcoding to downsize video files on the fly and play them back on my android phone. I read the Mencoder and vlc documentations and am trying to figure out an open source method and i don't mind setting up an apache server and writing some code to get a web interface.
I am working off of a recent clean install of Lucid (10.04.02) and I have relatives in Hawaii and this morning I tried to go to kitv.com to watch the live tsunami issues. Only to learn that the live feeds would not work.
I have gone and installed the gstreamer plugins for mms as well as the vlc plugin for the same. I have tried with both chrome and firefox and to no luck on getting the live feed to work. I have no problems getting the videos to play from hulu or ..... so I am at a loss as to why I am having such issues.
I will post output of any commands that may be needed.
With FireFox I have installed mediaplayerconnectivity and have it setup for vlc to launch on any mms streams. With the live feed I get the following error:
Code: Your input can't be opened: VLC is unable to open the MRL 'mms://a1064.l1289153063.c12891.g.lm.akamaistream.net/D/1064/12891/v0001/REFlector:53063'. Check the log for details. No clue on how to check the log for details...
I successfully installed darwin streaming server .. I stream Audio through internet well but videos I can stream locally in my network only .. when I am connected to internet outside my network .. it doesn't stream I think their must be ports opened for that .. or any 1 have any ideas .. the audio is streamed on port 8000 .. video is streamed on port 7070 but locally only .. I opened those 2 ports in my router only the audio is working .. also I opened ports 554,7170 disabled the firewall of the router .. is it a problem of ports or something else .
Amarok's video applet isn't working for me, it tries to play a selected video but only shows a blank background in the applet. This function worked in earlier versions of Amarok / KDE. I've tried Gstreamer, VLC and Xine phonon backends with same result. I don't think it is codec related as video/flash playback is fine in other apps.Currently using Suse 11.3 x86_64 / KDE 4.5.5 / Amarok 2.4.0 with xine backend
I am trying to record streaming flash video to multiple files each limiting upto 10 mins.Thinking of two possible ways to script,1) saving the files with 10 minute time limit on the fly as I record2) record the whole video as single file and split into multiple files with time limit.
I am using ubuntu 10.10 on Dell Inspiron 1525 dual boot with vista. My concern is streaming online videos through websites such as BBC iplayer, sky news, ....., NDTV news channel, etc. Videos are streaming perfectly fine as long as they are not running on full screen but if I try to run them on full screen video freezes (after a few minutes, say 5). Interestingly, sound does not stop. I can still hear the latest news updates but the video does not correspond. Same videos are running fine whether full screen or not in vista.
So for the last, oh, three or four hours now, I've been trying to get videos to play properly in Ubuntu. I have the default player, I have vlc, I (apparently) installed mplayer, but it won't play anything at all.
I was having horrible screen tearing with standard definition .avi's in vlc, fixed that by setting vsync in catalyst control center to always on or whatever it is.
Now, I have tried to run a 720p x264 video. It PLAYS, but not well. Audio is fine, however video is all jerky in VLC, and in Totem it's just a mess of screen tearing (although the video does no jerk on that player).
I have just spent HOURS trying to get VIDEOS TO PLAY. This makes no sense. Playing a video should be the simplest thing in the world for any OS to do, but with Ubuntu it is like pulling teeth. I have NEVER been so frustrated while using a computer. What is going on here?
BTW, I installed every single thing needed to use mplayer but it still does not work. The player comes up but will not play any type of file.
My system specs: 2.2Ghz dual core (intel) 3gb ram 1GB radeon hd 4650 vid card asus ipibl-lb mobo
I was really enjoying Ubuntu until I got around to trying to watch some videos. Now I am maybe minutes away from going back to vista. At least on there I can watch full 1080p videos if I want with no problems.
When I play a video web stream full-screen, the image randomly freezes. I can still move the mouse and hear the audio, but I can't click on anything, and I can't get out of full-screen. No keyboard commands that I know work, and so I end up having to hold down the power button to kill the machine.
This didn't happen in Ubuntu, so I'm pretty sure it's not a hardware issue. And I changed the power management settings to do nothing, but it still happens. So, I don't know what the deal is. Should I try a different flash player (I have the adobe player as default)?
