  • IE6 connection interruption in Comet streaming

    - by Konrad
    Hi, I am using a forever frame (COMET streaming technique) and in IE6 whenever a user clicks on a link (to even just basic JavaScript method) the connection is immediately dropped and has to be manually refreshed. Has anyone come across a similar issue and / or know how to address it?

  • reduce bandwidth streaming mp3s php...

    - by Scarface
    Hey guys, quick question for any experts out there. I am allowing users to upload and post mp3s so other users can listen to/stream. I was wondering if anyone had any tips for reducing bandwidth, or any tips or methods for streaming mp3s. I currently just reference the location of the file with my flash mp3 player after the file has been uploaded. I would ask about images as well, but I am pretty sure they can be compressed using gzip or mod_deflate

  • Streaming HTTP response, flushing to the browser

    - by synic
    I've got a view like the following: from django.views.decorators.http import condition def stream(): for i in range(0, 40): yield " " * 1024 yield "%d" % i time.sleep(1) @condition(etag_func=None): def view(request): return HttpResponse(stream(), mimetype='text/html') However, it definitely doesn't seem to be streaming at all. All the data is dumped at once, at the end, after about 40 seconds. How can I get it to flush correctly?

  • VLC (Server) re-stream Security Camera Feed

    - by Aaron
    I purchased a Swann Home Security DVR system and was hoping for some help on how to duplicate the streaming video on my server. In order to get their web view (streaming video in the browser) to work, I had to install the following plugins: HiDvrPlugin.dmg for mac. Hidvrocx.cab for Windows. I was originally thinking it was a sign of some form of DRM? Maybe. Maybe not. HTML wise, the following code is in the source of the safari version of the web view: <embed pluginspage="SurveilClient.dmg" width="10px" height="10px" type="application/x-scplugin" id="MacDiv" style="height: 592px; width: 720px; left: 278px; top: 61px; "> It seems to be the main display area. Using wireshark, I am able to see that the video stream is on port 9000. However, I have no idea what type of stream it is. I've tried opening it in VLC with no such luck. http://dvr_ip:9000 tcp://dvr_ip:9000 My hope was to do the following to redistribute the feed vlc dvr_ip:9000 --sout h264-version-on-localhost:3000 TLDR; Trying to re-distribute a stream from a security camera (can't tell the format) using vlc (re-distribute via h.264 / HTML5). Not sure how to accomplish this. Is it possible that the software has some type of DRM that only the plugins can decode?

  • torrent downloads not showing on Squid log

    - by noobroot
    hello, i have just a few months working as sysadmin, hence i still have lots to learn, first thing id like to do is as follows: We have an OpenBSD 4.5 box acting like firewall,dns,cache etc, the box has 2 network cards, one conected directly to the internet and the other to our switch, i used to work with sarg for the log analysis but then changed to the much faster free-sa. I use a daily free-sa report to check the bandwidth usage and report our top 5 bandwidth consumers (3 days a week being #1 and you will be buying the pizzas :D, we are a small company ~20 so we are very familiar). this was working really good until recently, one of us required to download some stuff via torrent (~3GB) and since the pizza rule is active for non-work related downloads, he told me (verified) that his download was indeed work related so i would dismiss that 3GB off his quota, but to my surprise the log didnt showed that 3GB, since his ip consumption was only around 290MB. More recently, since the FIFA world cup started, we know that some of the employees are watching the match's streaming, we know it and we dont care about it since, like already stated, we are a small company so we dont have restrictive policies, we all can chat, watch youtube, download anything we want BUT we are only allowed 300MB a day otherwise you'll get in the top5-pizza-board, anyway, that streaming consumption is also not showing in the free-sa reports. So my question is, why is these data being excluded from the reports? im thinking that the free-sa reports list only certain types of things but im also thinking if are the squid logs the ones that are not erm... logging these conections. Any help, guide, advice or clarification is appreciated.

  • Windows 8 DLNA streaming of MKV files

    - by dbb
    I have a Samsung TV that is capable of playing MKV files. The Windows DLNA Play To menu that appears when you right-click a media file does not support MKV files, but a simple trick has been to change the file extension from .mkv to .avi so the Play To context menu item would appear. At that point I could successfully stream from my computer to my TV. However, this does not appear to work in Windows 8. Doing the same thing in Windows 8 causes the Play To window to open but the file does not get played. Dragging and dropping the file in the Play To window causes it to be silently ignored. Using actual AVI, MP4, etc. files works, of course. It appears Windows 8 is now doing some kind of validation on the file that Windows 7 wasn't previously. The Play To window does not show any kind of obvious error message or warning and there is nothing in the Windows event log. So, is there a way in Windows 8 to stream MKV files to a DLNA device without converting it to another container format? I would rather not use extra third-party software, but I would consider it if it's purposefully designed for this simple case rather than a more robust "media library/server" solution.

  • Any screen capture software that captures webcam, microphone inputs too ?

    - by mohanr
    I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,

  • How do you play or record audio (to .WAV) on Linux in C++? [closed]

    - by Jacky Alcine
    Hello, I've been looking for a way to play and record audio on a Linux (preferably Ubuntu) system. I'm currently working on a front-end to a voice recognition toolkit that'll automate a few steps required to adapt a voice model for PocketSphinx and Julius. Suggestions of alternative means of audio input/output are welcome, as well as a fix to the bug shown below. Here is the current code I've used so far to play a .WAV file: void Engine::sayText ( const string OutputText ) { string audioUri = "temp.wav"; string requestUri = this->getRequestUri( OPENMARY_PROCESS , OutputText.c_str( ) ); int error , audioStream; pa_simple *pulseConnection; pa_sample_spec simpleSpecs; simpleSpecs.format = PA_SAMPLE_S16LE; simpleSpecs.rate = 44100; simpleSpecs.channels = 2; eprintf( E_MESSAGE , "Generating audio for '%s' from '%s'..." , OutputText.c_str( ) , requestUri.c_str( ) ); FILE* audio = this->getHttpFile( requestUri , audioUri ); fclose(audio); eprintf( E_MESSAGE , "Generated audio."); if ( ( audioStream = open( audioUri.c_str( ) , O_RDONLY ) ) < 0 ) { fprintf( stderr , __FILE__": open() failed: %s\n" , strerror( errno ) ); goto finish; } if ( dup2( audioStream , STDIN_FILENO ) < 0 ) { fprintf( stderr , __FILE__": dup2() failed: %s\n" , strerror( errno ) ); goto finish; } close( audioStream ); pulseConnection = pa_simple_new( NULL , "AudioPush" , PA_STREAM_PLAYBACK , NULL , "openMary C++" , &simpleSpecs , NULL , NULL , &error ); for (int i = 0;;i++ ) { const int bufferSize = 1024; uint8_t audioBuffer[bufferSize]; ssize_t r; eprintf( E_MESSAGE , "Buffering %d..",i); /* Read some data ... */ if ( ( r = read( STDIN_FILENO , audioBuffer , sizeof (audioBuffer ) ) ) <= 0 ) { if ( r == 0 ) /* EOF */ break; eprintf( E_ERROR , __FILE__": read() failed: %s\n" , strerror( errno ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } /* ... and play it */ if ( pa_simple_write( pulseConnection , audioBuffer , ( size_t ) r , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_write() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } usleep(2); } /* Make sure that every single sample was played */ if ( pa_simple_drain( pulseConnection , &error ) < 0 ) { fprintf( stderr , __FILE__": pa_simple_drain() failed: %s\n" , pa_strerror( error ) ); if ( pulseConnection ) pa_simple_free( pulseConnection ); } } NOTE: If you want the rest of the code to this file, you can download it here directly from Launchpad.

  • Capture live streaming

    - by acidzombie24
    I want to capture a rtmp stream. The videos are live, different every day and usually i cant tune in because i am busy at work doing something :(. I would like to capture the stream however they use anti capturing techniques (its live and free so i dont understand why). I tried orbit downloader without any luck. The url seems kind of weird (judging by grab++). It has || in it and other urls. What applications can i use to capture this? i am open to using linux

  • Voices disappear when using headphones.

    - by James
    How do I declare a variable in C? P.S. I have a pair of SteelSeries Siberia headphones. I've noticed that when watching some films the voices are completely silent, yet when I unplug the headset and listen through my speakers they are there and sound normal. I have no other software that could be interfering with it and it happens regardless of the software I use for playback (I've tried VLC, WMP and Quicktime). It is so strange, and it almost sounds deliberate - the rest of the audio is untouched but voices disappear. The films only have single audio tracks, and it doesn't happen with every film. Can anyone give me any hints as to what could possibly cause this? I am stumped!

  • WinXP keyboard input repeat rate problem

    - by Victor Sorokin
    I have problem similar to http://superuser.com/questions/33981/problems-with-kvm-switch-and-keyboard-repeat-rate-on-windows-xp: When I press and hold some key it's repeated random number of times, after that repeat stops and I need to release key and press it again to make repeat continue. If there's simultaneous sound playback and repeat is stopped, sound's stuck while I hold key with unpleasant drumming as if there's some audio problem. This issue is reproducible in WinXP Safe Mode. On the same config under Linux there's no issue. My config: List item PS/2 Logitech Keyboard USB Mouse MB M3A/H-HDMI WinXP Pro English SP2 with added Russian layout (WinXP loads via GRUB2) Realtek audio drivers for AC97 Thanks for your suggestions J

  • Local Live Quicktime Video Broadcast, latency?

    - by Snowwire
    I'm looking into the feasibility of using a local server to distribute live video of a conference to delegates in the same room. They would still hear the live audio coming from the speaker, so only the video would be streamed. I was considering a Darwin Steaming Server (a lot of iPhone users to support) and encoding with H.264. My main concern is latency across the network. Even with everything running locally, would there be lip sync issues between the live audio and the 'live' video stream? It feels like there will be problems given the encoding, broadcasting, decoding to be completed, but I've never done any like this before so thought I would check. Thanks

  • Are there any free voice transcription software?

    - by netvope
    I have some 1-hour-long voice recordings containing useful information that I may need to look up in the future. Instead of transcribing them myself (which will take me many hours), I want to automate it using software. I don't need an accurate transcription; it's OK as long as I can get an idea of what was being talked about by skimming over the transcription. With this, I can quickly figure out which part of the audio contains the information I need, and is much more convenient than seeking randomly. In theory I could write a program to split the audio into 3 minutes chucks and pipe them into Google Voice's free voicemail transcription service... But I hope there are better solutions. Do you know any free voice transcription software? Note: Free trials are also acceptable

  • Fuzzy Sound / Crackling

    - by Walter White
    Whenever I play music through my headphones on my laptop, I get a little bit of fuzz or cracking that is noticeable at lower volumes. When I listen through my phone, the sound is much clearer, both when music is playing and nothing is playing. The noise is more noticeable with my Sennheiser 280 PRO headphones than with earbuds. Is there anything I can do to improve audio playback on my laptop? I am surprised that the audio quality is better on my phone than my laptop which should have better hardware.

  • Turtle Beach Headset Chat Volume Wheel on Windows

    - by Todd Freed
    I have this headset http://www.turtlebeach.com/product-detail/headsets-legacy/ear-force-x11/235 I am using it with a Windows 8.1 PC using digital audio out on my motherboard (no dedicated sound card). The cable has 2 volume wheels labelled "Game" and "Chat". I would like to be able to control, say Google Hangouts or Skype volume with the chat wheel, and all other audio with the other wheel. Is this possible? The closest thing I can find is "Communications Device" vs "Device" under the Sound control panel in Windows.

  • Video conferencing software that allows a participant to mute individual users

    - by Chris Dutrow
    Have a few people working in an office and then a few more people working from home. We would all like to video chat skype-style, but for the people in the office, everything that is said by someone in the same room "echos". The echo is because the hear it one time through the actual air, and then again through their headphones or speakers: Unsure of the best way to solve this problem, but one way seems to be to use an application that enables the user to mute audio from another participant. Then the people in the office could mute all audio from other people in the same room, thus removing the echo effect. Any suggestions or ideas? Thanks so much!

  • HDMI Sound for HTPC

    - by Brent Arias
    I have the (perhaps) the same problem as stated in this other HDMI sound to HTPC question. I tried the advice of clicking on the speaker in the system tray. I can see the HDMI audio device I want to use. That device claims to be functioning properly. But there is no sound, and it won't let me select it as the active audio device. When I click on the troubleshooter, it says that there are no speakers connected. I would think this is because my computer us unable to pipe sound through the video card (preventing the HDMI from carrying it), except that it truly claims that it has an HDMI sound device that is working correctly. So I'm not sure what is wrong at this point. Thoughts? My system is Windows 7 x64. In case it makes a difference, the video card I'm using is this GeForce GTX 560

  • How do I relay output from a soundboard into input on skype?

    - by Anthony
    I'm trying to find a way to play audio from flash soundboards to people on skype. I apparently do not have Wave/Stereo mix/What u hear supported on my soundcard (I have windows 7 professional). I only have one soundcard, and I'm usually using headset. However, I have another laptop with windows vista on it that does have stereo mix available. The problem is, it still doesn't work. When I click an audio bit it just doesn't do anything. It plays on my end, but not to the person on the other end. Is there a way to do this? What am I missing?

  • On Windows 7, how can I tell if a recording is multi-channel without third party tools? [migrated]

    - by engineerchuan
    A customer has an audio that is confidential and can't send it to me. He also would not like to install other tools. He has a basic Windows 7 install. Is there any way to tell whether the recording is one channel or two channel? Normally, I would just get the audio and soxi it. Or, I would tell him to install Audacity or equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get number of channels but bit rate already factors in number of channels. Sorry I'm not giving you a lot to work with.

  • iTunes and Hulu Playback Choppy and Slow?

    - by Bart Silverstrim
    Specs: Windows XP, latest updates 1.7 ghz Pentium 4 1 gig ram DirectX 9.0c NVIDIA GeForce FX 5200 with 256 meg RAM OpenGL 2.1 The story: Okay, I had an older system laying around that I figured I would try turning into a mini-media system to connect to our TV. I put together a lot of older parts, got it into working order, etc. and hooked it up and voila'...slower, but usable system that displayed to the TV. It could run some things decently. I put in iTunes, it played video okay. Not great, but okay. Played Hulu and since we have a 1Mb download rate, the minimum for their site, there were some choppy moments when watching their shows, but I found that (sadly) changing resolution to 800x600 seemed to help with the issue when running full screen. I downloaded the application called Boxee and installed it. It wouldn't run; apparently the video card in the system supported OpenGL 1.2, and needed at least 1.4. I bought a cheap card, the 5200, with four times the memory in it and support for OpenGL 2.1. Installed, everything seemed fine. iTunes seemed to run fine, the video driver (PNY video card) came with OpenGL 2.1, and Boxee finally ran. I then upgraded to the latest drivers for the video card and ran the DirectX updater from MS. After that, the OpenGL Extension Viewer wouldn't run. It just stayed as an icon in the task bar. Also, any and all videos in iTunes stuttered and went out of sync horribly. Unwatchable. I tried watching Hulu video in Boxee, and it displayed video like it was a series of stills in a very bad powerpoint. Playing straightforward audio-only came through fine, no stutters no hiccups. I tried system restore to roll back updates to pre-directX updates (I thought that seemed to be the time that triggered the weird behavior), no joy. I tried uninstalling and reinstalling the video drivers. I installed updated audio drivers (ensoniq audiopci), nothing helped. I finally wiped the drive last night and tried reinstalling everything and restoring my iTunes content via an import from a backup. Fresh install, no updater on the video card or directx. the problem was still there although I haven't tested Hulu, the iTunes player is still stuttering like crazy if I play video, fine if I play audio. I know the processor isn't high in heft, but with one gig of RAM and the fact that it seemed to do okay before I thought that the problem must be software related. Has anyone else run into this sort of issue and have a solution other than "buy a new computer"? What specs seem to work with video at the low end for you? Right now the system is of little use other than keeping my music library and iTunes apps synced with my iPod.
