  • HD Video Capture Card w/ Good API?

    - by Sheep Slapper
    Does anyone here know of a good HD video capture card that has a good (comprehensive) API? I administer a few servers that do some video encoding right now, but when we make the switch to HD cameras, they won't be sufficient. In addition to this, the servers we have now are black boxes, closed to me except to start/stop the video capture device. I'd like to be able to roll my own, so we can better integrate it with our existing systems, but I know almost nothing about what kind of HD capture cards are out there, and if I can avoid spending money just to test their APIs that would rock. So does anyone have any experience with this? All our other software is in C#, and I'd like to set up the new servers with web interfaces to start/stop the capture (also in C#, using .NET 3.5 probably). I'm not sure how language specific these APIs would be, but that's what I'm working with just as a reference point. I appreciate any help the community can give!

  • How can I prevent static when PC is plugged into an amplified speaker system?

    - by Kyle
    I've plugged a computer into an amp, using a 1/8 inch male extension cord, into a female adapter, that adapts into a male microphone 1/4 end. That being said, the amp sits at about half volume all the time because there are other things that play on it. (This issue is not flexible, nor is changing the amp) The problem is that now, even when I mute out the computer, you hear some static in the background. I was wondering some about some solutions (preferably multiple).

  • ffmpeg, vlc - Unable to find input stream

    - by zozo
    Good day to all... I have some "little" problems with ffserver and ffmpeg... What I need to do is to broadcast a live video. So I got the cam... used vlc and used send stream option. I sent it to 192.168.1.9:64555, which is a virtual machine on the same computer, running centos. On the virtual machine I run the command ffmpeg -i 192.168.1.9:64555 output.mpg. The response is "unable to find file whatever". Can any1 tell me what I did wrong? Thank you and have a great day. Print-screen with error:

  • Properties!Details (run-time length)

    - by user33666
    When you take clips and turn them into computer playable files, whether .TS or .MOV or .MPG, .MP4, .VOB, etc., do you as the producer actually manually write into some field in a "Details" section of your video editor what the video length is, so that it can be read by the eventual user's video player? Or is this activity performed automatically by the video editor? I'm asking because: when a mouse is passed over a file line item in Windows 7 Shell (Windows Explorer) a little box is displayed where the mouse meets the file line item and provides simple name and size properties, one of which (if it's a media file) is run length. How does that figure get there into the file (later to be read be Windows or OS X)? Thanks for any info.

  • TV Playout software for Windows Server without DirectX?

    - by Joel Kennedy
    I am trying to find a TV Playout software (video mixer) for Windows Server 2003/2008 which can stream via rtmp to Justin.tv without the need for DirectX. The reason for this is that the server which would run the TV Playout software is hosted/virtualized via an ESXi server, and does not have DirectX support. Even if there was software that could just stream a playlist of video files to Justin.tv that would be a start. Thanks

  • Real Time Sound Leveler

    - by Soldier.moth
    Lately I've been annoyed with Hulu as the commercials are significantly louder than the actual show. This has caused me to wonder if there existed any application either generic or specific to Hulu or Firefox to reduce the difference in sound volume between the show and commercials.

  • Windows 7 laptop's volume with headphones way too loud

    - by jcao219
    I have two headphones, neither has any amps or volume control, and both have the same problem with this computer. I normally have the volume on 10%, and that is optimal. I'm still very afraid that someday it will be at 100% and i'll accidentally have my headphones on. I tested how loud it is at maximum volume -- it's earsplittingly loud! In fact, it's so loud that if I lay the headphones down on the table, I can listen to a song perfectly clearly from meters away. Is there any way to make the volume control more safe for the ears?

  • Lighttpd - byte range request doesn't work. can't stream mp4

    - by w-01
    Am attempting to use the lastest flowplayer. (if it could work it would be pretty awesome btw) http://flowplayer.org One of the cool things about it is it uses the new HTML5 video element and supports random seeking/playback. In order to do this, you need a byte range request capable server on the backend. Luckily I'm using Lighttpd 1.5.0 on the backend. Unfortunately the current behavior is that when I do a random seek, the video simply restarts itself from the beginning. the docs say: "For HTML5 video you don't have to do any client side configuration. If your server supports byte range requests then seeking should work on the fly. Most servers including Apache, Nginx and Lighttpd support this." On my page, using chrome web developer tools, i can see when the video is requested, the server response headers indicate it is able to acce[t byte ranges. Accept-Ranges:bytes when I do random seek in the player, I can see that that byte ranges are request appropriately in the request header: Range: bytes=5668-10785 I can also verify the moov atom is at the front of the video file. My question here is if there is something else on the lighttpd side i'm missing in order to enable byte-range requests? The reason i ask is because the current behavior suggests that the lighttpd simply doesn't understand the byte range request and is just reserving the video from the beginning. Update it's clearer to put this here. As per RJS' suggestion I ran a curl command. in the response it looks like lighttpd is working as expected. Content-Range: bytes 1602355-18844965/18844966 Content-Length: 17242611

  • Noise when I try to convert flac to mp3 using vlc

    - by Josef
    I'd like to convert my flac files to mp3s using vlc and it's Media-Convert/Save function. The destination file is written but only contains awful noise. I've tried most of the predefined profiles (mp4, wav, etc.) and all of them seem to yield the same result. What's wrong?

  • Windows Media Player Object with Video_TS Files - No Sound Anymore

    - by user1624184
    I copied a bunch of my DVDs (yes, owned) to a drive and created a basic webpage to be able to search and play them. I am using the code at the bottom to create a Windows Media Player object and then play the video. The video files are pulled off the DVD in the original format so each movie has files like this: VTS_01_0.BUP VTS_01_0.IFO VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB VTS_01_5.VOB VTS_01_6.VOB This all worked great until just recently. On my dev machine, I can play the videos but now, all of a sudden, there is no sound. I have tried the following but no luck: The video is not muted and the sound is at 50% Under the sound icon, under mixer, I checked IE and it is fine Sound works fine using another program, says WinAmp Opening Windows Media Player directly from the Start Menu and then playing the same movie works fine and I get sound I ensured that the option in IE to play sound on websites is checked I can play sound on other people's websites where they have embedded WMP files I tried resetting all of the IE settings on the Advanced tab in IE I tried my website, with my code below on another computer, AND IT WORKS FINE! I tried copying the media files listed above from the computer that works fine to my dev computer and it still doesn't work. If I try using a ".wmv" file, the sound does work By the way, I am using Win7 with IE8. As you can see, this is driving me crazy! Why would it stop working on my one computer and the same code and files work fine on another computer? Any help would be greatly appreciated. <OBJECT id="mediaPlayer" width="640px" height="480px" style="position:absolute; left:0px; top:0px;" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" type="application/x-oleobject"> <PARAM NAME="URL" VALUE="E:\test\VIDEO_TS\VIDEO_TS.IFO" /> <PARAM NAME="SendPlayStateChangeEvents" VALUE="True"/> <PARAM NAME="AutoStart" VALUE="True"/> <PARAM NAME="uiMode" VALUE="full"/> <PARAM NAME="volume" VALUE="50" /> <PARAM NAME="PlayCount" VALUE="9999"/> <PARAM NAME="fullScreen" VALUE="true"/> <PARAM NAME="enableContextMenu" VALUE="true"/> </OBJECT>

  • Converting a bunch of MP3s to mono?

    - by Wil
    I have a bunch of stereo MP3s I'd like to convert to mono. What is the best way to do this? I would prefer something that would let be batch process them. I want to keep the quality as close to the original as possible. My files are also in different bitrates, so I don't want to make all files 320kpbs when some are only 128. Also, is there any quick way to see which files are stereo out of my entire library?

  • Why isn't sox able to convert to mp3?

    - by marue
    I installed Sox, i installed lame-398, but sox is not able to convert any file to mp3. It fails with the messages: ./../sox FAIL util: Unable to load LAME encoder library (libmp3lame). ./../sox FAIL formats: can't open output file `funktech.mp3': How can i check if lame has been installed correct? How can i get sox to find the mp3Library? edit: I did not install sox at all, it works without installing directly from the commandline. Lame was installed by following the instructions on their site: ./configure make make install which results in the following files being found in /usr/local/lib/ : libmp3lame.dylib, libmp3lame.la, libmp3lame.a Maybe symlinking libmp3lame.la, which is marked as executable, to /usr/bin would help?

  • Viewing movies/TV programs requires constant mouse movements or keyboard activity to watch…

    - by greenber
    when viewing a television program using Internet Explorer/Firefox/Chrome/SeaMonkey/Safari it constantly pauses unless I have some kind of activity with either the mouse or the keyboard. The browser with the least amount of problems is SeaMonkey, the one with the most is Internet Explorer. Annie idea of what is causing this or how to prevent it? My finger gets rather tired watching a two-hour movie! :-) Thank you. Ross

  • Need software to save videos from 4tube.com - to watch the videos smoothly

    - by Harold34
    Isn't there a programs that will capture screen writes at the hardware level? I have tried several Firefox add-ons, and several stand-alone programs, and none of them will save videos from this site. I even paid for Replay Media Catcher, and it didn't work, so I got a refund. (The website for the best Firefox video downloader I have, Downloadhelper, said Replay Media Catcher worked with that site.) I have a slow internet connection, and cannot watch videos smoothly unless I can cache them. This site (4tube.com) doesn't cache, when you restart, it reloads, when you pause it stops - so I need to be able to save the videos to be able to watch them.

  • Volume key occassionally changes relative volume in mixer

    - by bobobobo
    I find this a bit of a nuisance but I usually use the "volume up/down" key on my Microsoft ergo 4000 to change the volume of my system. The problem I'm experiencing is every so often, the volume of Winamp goes way down relative to the other apps in the mixer: So I don't always notice this right away, suddenly I can't hear Brandy warbling. And that makes me sad. Or mad. Or both. But it's a nuisance - is there a special key combination I need to avoid pressing to stop the mixer from imbalancing? Is there a way to disable this "app specific" mixer, because it is completely useless to me.

  • Large File Uploads? SWFUpload?

    - by Ethabelle
    So, we offer video services and have run into an issue with people uploaded large file sources. I realized that our developer was utilizing php HTTP uploads to handle this and that was causing the slow times & breakdowns. Now, they keep coming at me wanting to use SWFUpload, quoting it is utilized by YouTube, but I'm adamantly against it because -- well, flash. However, I don't really know of a -better- solution that works across all browsers. So I was wondering SWFUpload, which hasn't been updated in a year, is really the viable solution?

  • hosting environment for delivering FLVs

    - by Gotys
    What would be the ideal hardware setup for pushing lots of bandwith on a tube site? We have ever-expanding cloud storage where users upload the movies, then we have these web-delivery machines which cache the FLV files on its local harddrives and deliver them to users. Each cache machine can deliver 1200 mbits/s , if it has SAS 8 harddrives. Such a cache machine costs us $550/month for 8x160gb -- so each machine can cache only 160GB at any given time. If we want to cache more then 160gb , we need to add another machine..another $550/month..etc. This is very un-economical so I am wondering if we have any experts here who can figure out a better setup. I've been looking into "gluster FS", but I am not sure if this thing can push a lot of bandwith. Any ideas highly appreciated. Thank you!
