Ubuntu Multimedia :: Real-time Video Transcoding For Streaming?

Aug 24, 2010

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.

Ubuntu Servers :: Setup Real-time (or Near Real-time) Folder Synchronization Among 2+ Servers

Mar 23, 2010

what the recommended way to set up real-time (or near real-time) folder synchronization among 2+ servers. I looked a rsync but that doesn't sound real-time and it looks like its something that you might put in a cron once an hour.

Ubuntu Multimedia :: Can't Set Real-time Priority

Dec 20, 2010

Running qjackctl as root allows me to run the audio in realtime so it seems to be a permissions problem and it seems to me that lubuntu does not read the /etc/security/limits.d/audio.conf file when I boot.

Ubuntu Multimedia :: Installing Real-time Kernal Into Lucid?

Feb 24, 2011

install the latest real-time kernal into my current Lucid 10.04 distro? I know I could download and use Ubuntu Studio, but 1.7Gb is too much for my monthly download allowance to handle, especially when all I need it for is to address the major latency issues I have with Audacity.

Ubuntu Multimedia :: Webcam Real-time Face Recognition Software?

Dec 5, 2010

i'm working on a project, and I need a Software that's capable of recognizing face in real-time (I'll try to explain this, since my English is not that good) By this I mean that while my webcam is on (Not recording, I want it to be like a Videochat, where the recorded Images don't save on the HDD) it can recognize faces. I'm not that good on Linux, but I believe it's the best OS for the project I'm working on, since it's much more free than Microsoft.

Ubuntu Multimedia :: Streaming Videos Only Play Correctly Some Of The Time?

Aug 31, 2010

Over the past week or two I've been noticing that I've been having more and more problems with playing streaming videos. I haven't been able to find anything consistent about when the videos don't play correctly. Theres been videos where I've just had to wait a day or two to see even though I know from other people that theyre working. Sometimes I get nothing, sometimes its just sound and sometimes its just video. It doesn't seem to depend on the websites either, earlier today I was able to get one video on a webpage to play correctly but the other one on that page would only give me sound for a couple of seconds and then stop like it was buffering even though the status bar showed it had loaded the entire video. I don't think its just a firefox problem either because I was having the same problems at the same websites running opera as well.

Ubuntu Multimedia :: Streaming Video (MP4) To PS3 And/or Xbox 360

Mar 3, 2010

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.

Ubuntu Multimedia :: IP Camera Video Streaming

Apr 6, 2010

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?

Ubuntu Multimedia :: Streaming Video Over The Internet?

Jun 16, 2010

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.

Ubuntu Multimedia :: Streaming Video Is Choppy

Aug 8, 2010

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.

Ubuntu Multimedia :: Streaming Video Is No Good

Nov 1, 2010

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.

Ubuntu Multimedia :: Can't Log Into CNN Live Streaming Video / Fix It?

Aug 3, 2011

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.

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.

Ubuntu Multimedia :: Get Video Streaming Working To Iphone?

Sep 29, 2010

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?

Ubuntu Multimedia :: Video Streaming On Ancient Hardware?

Jan 10, 2011

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.

Ubuntu Multimedia :: Cannot Get Streaming Video Based On WMMS To Play

Mar 11, 2011

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:

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...

Ubuntu Multimedia :: Online Video Streaming Freezes On Full Screen

Nov 25, 2010

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.
