Ubuntu Multimedia :: 1080p HD With DTS Stuttering/jittering Whatever Call?
Jul 4, 2010
This forum has been a wonderful treasure of knowledge. I am stuck up with something thats getting onto my nerves. I have installed lucid and followed the perfect desktop guide.
I have a mkv file (4.6Gigs) 1080p HD with DTS 5.1 audio. when I play the file either of the video or audio gets stuck (mostly video) I tried every possible configs from this forum but in vain. Im using Dell LAT D830 with 2GB RAM 2.2GHz CPU NVIDIA Graphics.
when i play a video (normal and full screen) there are some vertical lines appearing in the video (it actually stutters), this happens in videos and other online video sites as well. i have installed the nvidia software for my graphics card also.
I ended up getting 1080p playback working perfectly with vlc on my 1201n about 2 months ago, but then I decided I'd reformat my system to clean it out a little. There's other tutorials out there, but none are as straightforward as that one. I literally copy and pasted the commands and it worked like magic...now I have the latest nvidia driver installed, but vlc 1.1 won't let me check the GPU acceleration box under Preferences > 'Input and Codecs'.
I remember that this tutorial gave you PPAs for debs of vlc pre-1.1 git files, and a list of all the necessary software to install (vlc, vdpau, smplayer). It was hosted on a site other than ubuntuforums, and it was the only one that worked at the time for me.
Anyone know what I'm talking about, or give similar links? I think with this new nvidia driver stuff is actually being slowed down a bit, but that doesn't explain why VLC won't let me activate GPU acceleration.
I'm seeing regular stuttering in PAL video when running at the default 1920x1080 50Hz but not apparent when I use nvidia-settings to switch output to 60Hz. It's most noticeable when the video pans and you can see the video stutter ever half second or so.
VLC says: "main input error: ES_OUT_SET_(GROUP_)PCR is called too late" when I am playing back most Bluray discs I have tried.
See this bug post for what I am talking about: [URL].... It has to do with playing back h264 video with ALSA.
Possible fixes: 1. Obtain VLC 2.2.2 - see below 2. Fix by Modax here: https://trac.videolan.org/vlc/ticket/10422 - not currently using dmix and not sure how this will relate to HDMI sound 3. Use Pulseaudio - this does not work for me to get HDMI sound and I do not use Pulseaudio as a rule
I have just tried to compile VLC 2.2.2 and the configure script finished properly but early in the build it fails.
With make the error is:
Code: Select alljason@MEDIA:~/vlc-2.2.2$ make -j4 make all-recursive make[1]: Entering directory '/home/jason/vlc-2.2.2' Making all in compat make[2]: Entering directory '/home/jason/vlc-2.2.2/compat' GEN dummy.c make all-am

And with compile the error is:

I have tried installing 3 different versions of libua-dev, 5.1, 5.2 and 5.3. What could be the problem?
With the bugged audio drivers I'm going to replace the computer but it would still be nice to be able to know the solution to compiling VLC 2.2.2.
In Karmic's Amarok 2.2, when you pause and then play, the sound usually stutters a few times before it starts playing smoothly. I originally thought this was a pulseaudio issue, as stuttering problems have been reported with pulse, but that wouldn't explain why sound is fine in mplayer, audacious, vlc, dragon player, and virtualbox. Only amarok has this problem. I found the cause of the problem: phonon-backend-xine. These steps will get rid of the stuttering problem:
1. Install phonon-backend-mplayer. You can get it from Rog131's PPA: [URL]
2. In Multimedia and Sound Configuration, which you can reach through amarok's Playback settings, on the Backend tab, click the arrows to move mplayer up above xine.
3. Quit and restart amarok.
There are some tradeoffs for good sound. Amarok seems to have some bugs when the sound backend is not xine, and bookmarks and OSD are broken when this backend is playing the sound. When you quit Amarok, it can't bookmark your place so it doesn't restart from where you last were, and after the track changes once, the OSD when you hover over the tray icon only says "Amarok - No track playing." You have to open Amarok to find that info. Are there any settings I can access for phonon-backend-xine that could fix the stuttering issue? The problems with the mplayer backend are minor compared with xine's bad sound, but I would like nice sound, OSD, and bookmarking.
I'm using currently ubuntu 10.10. Having a nvidia gt220 with the proprietary drivers. I used compiz for a while. It works quite well, with vsync on and so on. But one thing bothers me all the time: In any opengl program (like a game or the unigen benchmarks) or on video playback (no matter if its the default video player, xbmc or what ever) I see some kind of stutter. About every second or so it jumps one frame forward and then two back. Till the next second it plays fluid.
To be able to observe this easily you need a video (or a opengl scene) where the whole screen scrolls in a medium speed but smooth. Than you can observ how it "jumps" every second. If the scrolling is too slow you wont observe it. Now, if I turn composite off this disapears. All play fluid. Ofcourse I get tearing as long as I do not also disable the composite extension in the xorg.conf, but this is another story. Is there a possibility to fix this stuttering with compiz active? Cause I use this pc to watch movies quite often so this would render compiz unusable.
i recently did a clean install of 10.10 to an old box i had so i could mess around with it and learn. however, all audio (and videos too) would stutter and play very quickly (a 1 minute videos video would play in about 45 seconds). so i followed the solution found here: [url]
this fixed the playback problems perfectly, however, i lost the volume control applet in the upper-right of the screen. reinstalling to volume control and then adding the "indicator applet" back to the panel adds a non-functional volume control icon and an additional mail icon.
I have a high resolution file (1080p) encoded with H.264 and when I play it back, it lags at certain parts (and enough parts to destroy the job of watching the video).
I don't think that my computer is that crappy and it has been able to play many H.264 encoded files with high resolution - so there is always a possibility that this file is just encoded poorly (lacking a better computer, I cannot test).
For information, I'm running Ubuntu 9.10 64 bit. I have a Intel Core2 Quad CPU Q9550 (@2.83 GHz). I have 8 GB of RAM (forgot the speed off the top of my head). And a Nvidia GeForce GTX 280 (1 GB of memory).
During the playback, the RAM is far from being completely used; however, it seems that one (and only one) of the cores of my CPU becomes saturated at 100% precisely at the moments in which the file lags. When the CPU utilization is below 100%, there is smooth playback.
My question is - is it possible to use all four cores during playback, or is such a process not capable of easy parallel processing.
Another side question is, how can I be sure that my GPU is being used in the decoding process - or is that also being under-utilized?
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've just made the move to openSUSE* and after the installer seemed to bork my xorg.conf because of my Wacom tablet things have been going quite smoothly. My only problem at the moment is that MP3 playback through Exaile, Banshee or Totem stutters and pauses several times per track or more. The only commonality I can see is GStreamer, but nothing is giving me errors to the console.
* I ditched Fedora to get better Monodevelop support after using Redhat 7.3 and 9 followed by FC 3 and 6 then Fedora 7, 8, 9 and 10. The Ubuntu forums seemed to keep giving me occasional answers to questions, but the Suse build service gave me the RPMs, when the requirements matched.
I have some videos on my harddrive. In most of them the sound just stutters for a short while and then they work fine. But others the stuttering seems to go on. I must admit I didn't have the guts to check the whole videos...Its kind of torture to watch a full length music video with stuttering sound... Man...I'm asking so many questions here I'm starting to get ashamed of myself
I'm having trouble getting 1080p out my xfx 9800gt that has an onboard hdmi socket. No doubt my HDTV is 1080p (panasonic TH-427PZ70B a few years old now), and it will do and has run at 1080p 60hz.
It auto detects the display as simply panasonic-tv and outputs at 1080i. As I've been running mythtv with tv tuners this actually worked quite well as dvb-t is interlaced anyway and most ofthe HD video files I play are 720p. However I would like to run it at 1080p for all the usual reasons- especially as I have some 1080p files I'd like to enjoy in all their glory!!
This doesn't seem to be ubuntu specific as mandriva behaves the same, and makes no difference if I use the open source (default with 9.10), the official nvidia package or as I've just tried 10.04 with default and nvidia.
I've searched around for nvidia hdmi 1080p etc but can't seem to dig up anything useful. Surely I should be able to force the graphics card to output standard 1080p 60hz?
Should I be able to do this through xrandr by setting a modeline or in xorg.conf or nvidia control pannel!?
I had a problem playing full HD videos (1080p @ 30 fps), frames dropped, CPU utilisation (on 1 of 2 CPUs) maxed out etc.As I'm still stuck on Hardy I didn't find much stuff that directly answers my question on how to play this... After hunting about a bit the following two links gave me some idea of what needs to be done, namely install a new version of Mplayer that supports VDPAU (NVidia's hardware video acceleration solution).
[URL]
Luckily I had a NVidia video card that supports VDPAU and I had installed the NVidia proprietary drivers before [URL]To check if your NVidia card supports VDPAU please look at the proprietary driver release details.
Quote from Wikipedia:
"Currently only second generation of PureVideo HD bit-stream processor in some of NVIDIA's GeForce 8 series and later graphics cards hardware that has support since the Beta device driver version 180.06.[4] Unsupported hardware from the GeForce 8 series includes the 8800GTS 320/640MB editions and the 8800GTX. Later cards based on the G9x series cores e.g. the 8400GS and the 8800GTS 512mb (G92 core) are supported."
I usually play using VLC but was put-off from trying to upgrade that to CDPAU support because of this little detail from the Ubuntu forum links above:
Quote:
"VLC is available with vdpau by way of VA-API, in this PPA:[URL]However, to install it you'll have to upgrade your precious and very touchy ffmpeg packages. There have been a couple of SONAME upgrades since Karmic's ffmpeg was released, and this will inevitably result in breakage of anything that A) uses dynamic ffmpeg, and B) is not rebuilt against the new version, ie. every package that's on your system that didn't come from that PPA."
I've tried watching material in 1080p resolution on my notebook and i experienced some slowdowns, tearing, etc. Video is encoded by x264 and sound is flac 5.1, all in mkv container. I know it's quite heavy one, but it was playing quite good on windows+CoreAVC, so i expect no less from my shiny Ubuntu I did a bit of googling and found out that AVIVO/UVD/Whatever is already turned on by default in fglrx drivers when using Xv, yet CPU is struggling on 90-100% load. Is there a way to turn hardware decoding on? It doesn't seem to work by "default" (or i'm too desperate to acknowledge that hardware acc is already on and still struggling to decode this ).
Specs of my notebook:
Intel Pentium Dual-Core T4200 2.0 GHz Mobility Radeon HD4570 256MB with fglrx from maverick repo 3GB RAM (doh!) mplayer and codecs from medibuntu repo mplayer uses -vo xv -va pulse , ffh264 and ffflac codecs
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 am preparing to purchase a new laptop, with Ubuntu 10.04 built in, from System76 with 8.0 GB DDR3 1333 MHz RAM, ATI 4570 graphics with 512 MB GDDR2 memory, 500 GB 7200 RPM SATA II hard drive, and I get to choose a CPU. I am wondering: 1) Would I get better 1080p video playback performance with a dual core Core i7-620M or quad core Core i7-840QM CPU? 2) What is the best playback software in Ubuntu that takes full advantage of such a CPU, and also the GPU?
when I'm traying to watch 720p and 1080p movies, MKV format. The movie is breaking all time, do I need to install any codecs or extansions, or use another application.I tried VLC player, and it is same. Well i had same problem with Ubuntu 10.10 and could't fix it.
In practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab
I am trying to get a program running on Ubuntu 10.04 that I wrote and ran successfully on Ubuntu 8.04. It uses the ALSA sound interface. As part of the initialization it calls snd_pcm_hw_params() to write parameters to the driver. On 10.04 this call hangs (does not return). Here are the 'snd_' entries displayed by lsmod (actually: lsmod | grep snd):
Obviously the program compiles OK. Any ideas why snd_pcm_hw_params() should hang? Its arguments were fine when running under 8.04... My machine is a new Dell Inspiron 570.
I'm using a PS3 Eye, which seems to work out of the box on my Ubuntu 9.10 system (both Skype, and Cheese). When I have a pidgin chat window open for one of my contacts, in the media options (under Conversation) the audio, video, and audio/video option is ghosted out (non selectable).
I have the Video plugin checked (ticked), with the input video selected (the cam shows up in the list, and it's selected): for the Eye, I select for both the Audio and Video device. But when I close the plugin configuration window, it defaults back to "Default" which i'm guessing is part of the problem.The audio and video options in pidgin is relative to my system correct? So even if the other user doesn't have that capability, it'll still let me use audio/video for them?
I'm trying to get video calls to work using Empathy 2.30.0. I'm running the 10.04 beta right now, but I've had this problem ever since I installed Empathy. The problem is essentially that I don't even see the option to do a video call with my contact. I can do an audio call, but the option to do a video call is greyed out.
My webcam is built-in (the computer is a Dell Inspiron 1545n). I know that it _can_ work under Linux, as I regularly use Skype. Also, just after I upgraded to 10.04, I briefly had the "video call" option, but when the program crashed I tried to call, and then the option was gone again. What was strange is that for a little bit, before it crashed, my webcam was working, and I could see the image it was receiving. So it can't even be that Empathy just can't use my webcam.
Does anyone know anything about this problem? Everywhere I've looked says that Empathy should be able to make calls using GTalk.
I'm having a problem with Skype. Whenever someone calls me, the incoming call popup shows up, but I can hear no sound playing. Further, if I go in Options/Notifications and try to test the incoming call event, I'm having the same problem.
The .wav file exists and Skype can play it back. I have tested this by assigning that particular .wav to a different event, where it works as expected. Additionally, the other events, e.g. outgoing call, appear to be working normally. This would suggest, that the problem lies with the incoming call event, rather than the particular sound.
Right now in order to do some recording I use Skype and Skype Call Recorder, but Skype only does audio at 16Khz. Is there some other similar program that could be used that could also be recorded at a higher quality?
I have installed Ubuntu 10.10 on ASPIRE 5315 (intel celeron)Installed SKYPE BETA 2.1.0.8.1.I have external webcam which works with CHEESE ( I could see myself and takepictures).However when I open SKYPE onle telephone (voice) call are available. I Do not have the option for video calls. I do not have/see a tool bar or a side bar so I cannot make any change or test the video. I tried to delete and download SKYPE again and id did not work.What can I do ?If you post an answer please provide step by step since I am not familiar with ubuntu.
I'm using Ubuntu 11.04 x32 Today I started Skype and I couldn't hear the Skype logging sound. Nevertheles I could see the contacts online. When I tried to write messages in the chat they couldn't receive them. When I tried to call nothing worked. After that it seemed that Skype was completely blocked. I clicked with the right button on the green icon of Skype and chose "quit" but it wouldn't close. 1 I logged off from Ubuntu and on again. I opened Skype. I made right click in the green icon and chose "Options"
2 I went to the "Sound Devices" menu in the left part of the window
3 I removed the tick for "Allow Skype to automatically adjust my mixer levels"
4 I closed Skype and opened it again and the sound problem was gone.
Sound Recorder is working fine. But when try to make normal call or test call I cannot record sound my internal mic in SKYPE. As I speak something immediately the sound level of mic drops to zero. Alsa driver are installed. HDA intel conexant mic.
I am running Ubuntu 9.10 in a HP Pavillion dv7t Laptop. The webcam in the laptop is working fine, but when I try to place a video call to gtalk from Empathy it gets disconnected immediately. The regular chat and the audio calls work fine.
