  • Front panel audio replacement

    - by develroot
    I have experienced some problems with my headphones and it turned out the front 3.5mm audio jack is defective..and it doesn't make a good contact. I can't replace the jack because it's built-in. I am wondering if there are such things as "modular" Front panels to be inserted into the available external 3.5" bay and, of course, to support (natively, internal connector) Realtek HD Audio. (my case is Asus TA-K5, but I guess it doesn't make any difference)

  • merging video and audio with custom panning

    - by cherouvim
    I have: a video which has mono audio inside a audio (mono) I'd like to merge those two to a single video file containing: video from #1 audio from #1 full left pan + audio #2 full right pan Is this possible in ffmpeg using 1 command? I've tried the following which almost does this but the video/audio gets out of sync: ffmpeg -i video.mp4 -filter_complex "amovie=audio.wav [r] ; [r] amerge" output.mp4 -y I've managed to do it with multiple commands: #1 create right panned audio ffmpeg -i audio.wav -ac 2 -vbr 5 audio-stereo.mp3 -y ffmpeg -i audio-stereo.mp3 -af pan=stereo:c1=c1 audio-right.mp3 -y #2 create left panned video ffmpeg -i video.mp4 -af pan=stereo:c0=c0 video-left.mp4 -y #3 merge the two ffmpeg -i video-left.mp4 -i audio-right.mp3 -filter_complex "amix=inputs=2" video-mixed.mp4 -y It does the job, but is it possible with 1 command?

  • ASP.NET MVC ajax chat

    - by nccsbim071
    I built an ajax chat in one of my mvc website. everything is working fine. I am using polling. At certain interval i am using $.post to get the messages from the db. But there is a problem. The message retrieved using $.post keeps on repeating. here is my javascript code and controller method. var t; function GetMessages() { var LastMsgRec = $("#hdnLastMsgRec").val(); var RoomId = $("#hdnRoomId").val(); //Get all the messages associated with this roomId $.post("/Chat/GetMessages", { roomId: RoomId, lastRecMsg: LastMsgRec }, function(Data) { if (Data.Messages.length != 0) { $("#messagesCont").append(Data.Messages); if (Data.newUser.length != 0) $("#usersUl").append(Data.newUser); $("#messagesCont").attr({ scrollTop: $("#messagesCont").attr("scrollHeight") - $('#messagesCont').height() }); $("#userListCont").attr({ scrollTop: $("#userListCont").attr("scrollHeight") - $('#userListCont').height() }); } else { } $("#hdnLastMsgRec").val(Data.LastMsgRec); }, "json"); t = setTimeout("GetMessages()", 3000); } and here is my controller method to get the data: public JsonResult GetMessages(int roomId,DateTime lastRecMsg) { StringBuilder messagesSb = new StringBuilder(); StringBuilder newUserSb = new StringBuilder(); List<Message> msgs = (dc.Messages).Where(m => m.RoomID == roomId && m.TimeStamp > lastRecMsg).ToList(); if (msgs.Count == 0) { return Json(new { Messages = "", LastMsgRec = System.DateTime.Now.ToString() }); } foreach (Message item in msgs) { messagesSb.Append(string.Format(messageTemplate,item.User.Username,item.Text)); if (item.Text == "Just logged in!") newUserSb.Append(string.Format(newUserTemplate,item.User.Username)); } return Json(new {Messages = messagesSb.ToString(),LastMsgRec = System.DateTime.Now.ToString(),newUser = newUserSb.ToString().Length == 0 ?"":newUserSb.ToString()}); } Everything is working absloutely perfect. But i some messages getting repeated. The first time page loads i am retrieving the data and call GetMessages() function. I am loading the value of field hdnLastMsgRec the first time page loads and after the value for this field are set by the javascript. I think the message keeps on repeating because of asynchronous calls. I don't know, may be you guys can help me solve this. or you can suggest better way to implement this.

  • Chat Service / Server for ASP.NET

    - by denisb
    I'm looking to have a livechat service integrated within a site where I can create chat rooms on the fly based on participants tied to that specific area... Anyone recommend using a 3rd party service I can install on the server that integrated easily with .NET, or just build one using polling method? I'd like something with socket connection, but not sure what's out there that either cheap or free that I can use.

  • Ultimate chat-client API for .NET?

    - by Shimmy
    Does anyone know of a .NET API (source-code is preferrable of course) that I can access all the common chat clients thru it (GT, Yahoo, MSN, AIM, FB, ICQ, SKYPE and more)? I guess I am looking for a .NET library project that performs something like pidjin. I need it because I hate Pidgin's interface and functionality, and I want to have a Google-Talk desktop like UI. Any comments and tips will also be very useful. Thanks.

  • Recommendations on apache tuning for chat application

    - by sofia
    Hi, I have a chat application (xmpp / muc) that is going to be served by apache (we might change to nginx later but right now it's not easily done). If a user is in 2 rooms, he'll have between 2 and 4 active connections to the server (long-polling connections), so if we have 200 users per room and we have 5 rooms, what should the ServerLimit, MaxClients be set to? For example, these are the default values: ServerLimit 256 MaxClients 256 MaxRequestsPerChild 4000 Thanks,

  • “Unplugged” Chat with Me this Thursday

    - by ScottGu
    This Thursday (May 13th) I’m going to be doing another online LIDNUG chat session.  The chat will be from 10:00am to 11:30am Pacific Time. You can learn more about it here and join the chat at the appropriate time with this link. I do these chats a few times a year and they tend to be pretty fun.  Attendees can listen to me talk live via LiveMeeting, and can submit any questions they want to me.  I then answer as many of them as I can in the 90 minutes.  We’ll probably talk a lot about the new features in VS 2010, .NET 4, Silverlight 4, Windows Phone 7, ASP.NET 4 and ASP.NET MVC 2 this week. Hope to get a chance to chat with some of you there! Scott

  • iOS chat application design, sending/relaying the message over to the end user

    - by AyBayBay
    I have a design question. Let us say you were tasked with building a chat application, specifically for iOS (iOS Chat Application). For simplicity let us say you can only chat with one person at a time (no group chat functionality). How then can you achieve sending a message directly to an end user from phone A to phone B? Obviously there is a web service layer with some API calls. One of the API calls available will be startChat(). After starting a chat, when you send a message, you make another async call, let us call it sendMessage() and pass in a string with your message. Once it goes to the web service layer, the message gets stored in a database. Here is where I am currently stuck. After the message gets sent to the web service layer, how do we then achieve sending/relaying the message over to the end user? Should the web server send out a message to the end user and notify them, or should each client call a receiveMessage() method periodically, and if the server side has some info for them it can then respond with that info? Finally, how can we handle the case in which the user you are trying to send a message to is offline? How can we make sure the end user gets the packet when he moves back to an area with signal?

  • Timing issues with playback of the HTML5 Audio API

    - by pat
    I'm using the following code to try to play a sound clip with the HTML5 Audio API: HTMLAudioElement.prototype.playClip = function(startTime, stopTime) { this.stopTime = stopTime; this.currentTime = startTime; this.play(); $(this).bind('timeupdate', function(){ if (this.ended || this.currentTime >= stopTime) { this.pause(); $(this).unbind('timeupdate'); } }); } I utilize this new playClip method as follows. First I have a link with some data attributes: <a href=# data-stop=1.051 data-start=0.000>And then I was thinking,</a> And finally this bit of jQuery which runs on $(document).ready to hook up a click on the link with the playback: $('a').click(function(ev){ $('a').click(function(ev){ var start = $(this).data('start'), stop = $(this).data('stop'), audio = $('audio').get(0), $audio = $(audio); ev.preventDefault(); audio.playClip(start,stop); }) This approach seems to work, but there's a frustrating bug: sometimes, the playback of a given clip plays beyond the correct data-stop time. I suspect it could have something to do with the timing of the timeupdate event, but I'm no JS guru and I don't know how to begin debugging the problem. Here are a few clues I've gathered: The same behavior appears to come up in both FF and Chrome. The playback of a given clip actually seems to vary a bit -- if I play the same clip a couple times in a row, it may over-play a different amount of time on each playing. Is the problem here the inherent accuracy of the Audio API? My app needs milliseconds. Is there a problem with the way I'm using jQuery to bind and unbind the timeupdate event? I tried using the jQuery-less approach with addEventListener but I couldn't get it to work. Thanks in advance, I would really love to know what's going wrong.

  • Win 7 Media Center - TV - No audio on HD channels

    - by Chuzein Part II
    I wonder if you can help. I have recently purchased a PCTV Nanostick DVD-T2 290e I am running Windows 7 Home Premium 64bit and I use Windows media center for almost everything. I run a media center machine in my lounge through my Sony AV Amp onto my HD TV. I bought the Nanostick to watch ‘Freeview HD’ programmes when watching the TV through the Media Center – I also have a Sony Freeview Plus system that the Mrs uses. I installed the Nanostick with relatively no issues and as described by many user reviews Media Center picked up the new USB tuner and scanned all the new channels and I was presented with all the HD channels. The issue I have is that there is no audio sound from the HD channels but perfect video. SD works fine. The software that comes with the Nanostick works fine – both sound and vision are perfect for the HD channels. As mentioned, I run my Media Centre lots. I have an extensive DVD and BD collection stored on a server and DVD and BD all play perfectly through Arcsoft Total Media Theatre 5 – with no issues on either SD or HD. My sound card is built into my motherboard and that sends the audio signal to my gfx card and that in turn passes it through to my Sony AV Amp that decodes the audio to be heard on my 5.1 set up. Does anyone have any ideas. I have searched lots on the net and I cant find anyone else with the same issue. I am aware of codecs etc but I don’t really understand it. It also puzzles me that when I read the user/buyer reviews for this product so many people tell the story of faultless installations on the same kind of set up as me.

  • iPhone SDK: Audio Queue control

    - by codemercenary
    Hi all, I am new to the audio queue services so I have taken an example from a book called iPhone Cool Projects where it describes how to stream audio. I want to extend this to being able to play a continuous playlist of links to mp3 files like an internet radio. The problem with the example code it that it does not detect when a stream ends and does not call AudioQueueStop at any point, so I added a counter to number of buffers added to the queue, and then decrement this counter each time audioQueueOutputCallback is called by the queue. This works fine except if when the buffer count goes to 0, and then I add a call AudioQueueFlush(audioQueue) and then AudioQueueStop(audioQueue, false) I get an error. If I only call AudioQueueReset, it continues to load the buffers again, but plays them out faster then it loads them... getting stuck in a loop and then crashing. 2010-04-14 13:56:29.745 AudioPlayer[2269:207] init player with URL 2010-04-14 13:56:29.941 AudioPlayer[2269:207] did recieve data 2010-04-14 13:56:29.942 AudioPlayer[2269:207] audio request didReceiveData 2010-04-14 13:56:29.944 AudioPlayer[2269:207] >>> start audio queue 2010-04-14 13:56:29.960 AudioPlayer[2269:207] packetCallback count 2 2010-04-14 13:56:29.961 AudioPlayer[2269:207] add buffer: 1 2010-04-14 13:56:29.962 AudioPlayer[2269:207] did recieve data 2010-04-14 13:56:29.963 AudioPlayer[2269:207] audio request didReceiveData 2010-04-14 13:56:29.963 AudioPlayer[2269:207] packetCallback count 1 2010-04-14 13:56:29.964 AudioPlayer[2269:207] add buffer: 2 2010-04-14 13:56:29.965 AudioPlayer[2269:207] packetCallback count 13 2010-04-14 13:56:29.967 AudioPlayer[2269:207] add buffer: 3 2010-04-14 13:56:29.968 AudioPlayer[2269:207] done with buffer: 3 2010-04-14 13:56:29.969 AudioPlayer[2269:207] done with buffer: 2 2010-04-14 13:56:29.974 AudioPlayer[2269:207] done with buffer: 1 So this loop continues some 20 - 30 times and then it crashes. The first time it plays an audio file it queues up the buffers and then plays sound, but doesn't callback to delete them until some 100 or more have been played. Can anyone explain this behavior? I read that there was a limit of 1 audio queue for MP3 playback for the iPhone. Is that still true? If not then I suppose I should use another audio queue for the next mp3 stream. I've had a look through the apple docs but it doesn't explain this in any particular detail. A better insight into this would be great. TIA.

  • iPhone PlayAndRecord silences all system audio??

    - by Eamon Ford
    Hi, In my iPhone app I am trying to record audio and play iPod music at the same time, so I set the audio session category to kAudioSessionCategory_PlayAndRecord. But when I set this, all system audio (including vibrate) doesn't work anymore, although the iPod audio still does work. Does anyone know if this is a bug in the SDK or something, or how to get around it? Please help! Thanks in advance!
