• HTML5 video tag with multiple bitrate videos?

  - by Joanne

  I have MP4 video files encoding at different bitrate to be compatible for both iOS on Wifi and Edge connection. I would like to have them progressive loaded form my website using HTML5 video tag. video_big.mp4 encoded for iOS on Wifi H.264 Baseline, 25fps, 640x480, 500kbps video_small.mp4 encoded for iOS on Edge/3G H.264 Baseline, 25fps, 320x240, 56kbps My question is: How can I write the HTML5 video tag to serve video_big.mp4 to iOS devices that connected through Wifi, and serve video_small.mp4 to iOS devices that connected through Edge/3G? I'm running on PHP/Apache server. Thank you :)

• Creating a loading screen in HTML5

  - by espais

  I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

• Getting ready for learn html5

  - by vtortola

  Hi, I'm a desktop application developer, and I plan learning html5, but as it's not released, there is no (almost) published books and no too much infomation from beginners on the web... I fell I should start with html4 and the current web development skills. I think, I should start with html4, css and javascript... but there are so many technologies related that I get lost :D So, what current technologies will be sill used when html5 be released? I mean, what about "jquery" and "ajax"? I know they are javascript under the hood, but will they still make sense in the future? What would you recommend me considering that I have just a little bit of html knowlegde, almost null CSS and completely null in javascript? Thanks in advance.

• HTML5 Canvas compositing question (source-in)

  - by Alex Ciarlillo

  I am trying to recreate a page flipping type animation in HTML5 using canvas. The animation is based on ideas from here: hxxp://oreilly.com/javascript/archive/flashhacks.html but thats not really important. The problem I am having is that using the 'source-in' composite operation is not giving me the results I expect and would like clarification as to why. Here is the example: (i think it can only be viewed in chrome, not working in FF 3.6) http://acpound.fylez.com/test/example.html The black rectangle is supposed to act as a 'mask' for the page being turned over. All I want to see is the turning page in the areas where it overlaps the mask. The problem is the entire black rectangle is drawn, not just the area where they overlap. The source is all on the page. I know HTML5 isn't really being used yet, I'm just experimenting for my personal site and curiosity. Any ideas would be greatly appreciated.

• Will html5 and Javascript replace native applications?

  - by nimo

  I recently attended a conference on future of the web and web development and it was a lot of focus on HTML5 and how it will impact the way we look at the web and how we will use it. The majority of the speakers meant that it will replace native application on your desktop as well as in your mobile phone. I agree that you will be able to make a lot of great stuff with the new technology take bespin for example and the <video> and <canvas> tag will be amazing, but will it completely remove the need for native applications? Is there something you cannot do with Javascript and HTML5?

• Basics of html5 and canvas

  - by René Nyffenegger

  As I browse through different questions here, I see that there are a number of questions tagged with html5 and canvas, so I guess they sort of belong together. Now, I have absolutely no idea about the canvas (which is obviously (?) rendered in html5), but it seems that It could be useful one day in the future. So, in order to be prepared when that day comes, I'd like to know the basics about these things. I found a html snippet that is supposed to render such a canvas, but when opened in my browser (firefox) nothing is displayed. So, I guess I need a special plugin or another browser. My question: what are the absolute basic things I need to know and have in order to create a hello world thingy. Please bear in mind that I am completely new with this and don't need no fancy advanced stuff.

• HTML5 or Javascript game engine to develop a browser game

  - by Jack Duluoz

  I would like to start developing a MMO browser game, like Travian or Ogame, probably involving also a bit of more sophisticated graphical features such as players interacting in real time with a 2d map or something like that. My main doubt is what kind of development tools I should use: I've a good experience with PHP and MySQL for the server side and Javascript (and jQuery) regarding the client side. Coding everything from scratch would be of course really painful so I was wondering if I should use a javascript game engine or not. Are there (possibly free) game engine you would recommend? Are they good enough to develop a big game? Also, I saw a lot of HTML5 games popping up lately but I'm now sure if using HTML5 is a good idea or not. Would you recommend it? What are the pro and cons about using HTML5? If you'd recommend it, do you have any good links regarding game development with HTML5? (PS: I know that HTML5 and a Javascript engine are not mutually exclusive, I just didn't know how to formulate a proper title since English is not my main language. So, please, answer addressing HTML5 and a game engine pro and cons separately)

• 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!

• How to process audio in real time?

  - by user1756648

  I am giving some audio input through microphone. I recorded it in Audacity, it looks something like as shown below. I want to process this audio in real time. I mainly want to do this. 1) see real time audio amplitude vs time graph 2) perform some actions based on some thing (like if a specific type of hike is seen in audio, then do something, else do something else) Is there any python module or C library that can allow me to do this ?

• Does HTML5 have a feature that enables a user to add an icon to the Apps screen when "installing", and if not, when are they planning to add it?

  - by Jason Livesay

  I know that the mobile bookmark bubble might sort of work for iOS, but it isn't going in the same section. And for Android, bookmarking is really not going to cut it for a mobile HTML5 application install since users just don't think to go to their bookmarks and that bookmark process takes two or three steps. To me this issue of getting the application (bookmark) installed pretty much makes the rest of the HTML 5 features aimed at mobile HTML much less useful. I can't realistically expect users to prefer the bookmark install and launch process over regular apps, so I can realistically expect them to ignore my mobile HTML5 application and use a native app. The groups behind mobile HTML 5 features do seem to be pushing for HTML 5 apps adoption with things like Application Cache etc. To me it seems obvious that the bookmark bubble is not going to cut it. Someone please tell me they have addressed this or at least are working on it?

• Windows Vista/7: Managing multiple audio playback devices

  - by BrianLy

  I've got speakers (audio in) and headphones (USB headset with it's own soundcard) connected to my desktop computer. Under Windows 7, I can right-click the Audio Mixer and select Playback Devices and toggle between my these devices. Is there an easier way, perhaps a keyboard shortcut, that would make it easier to toggle? I'm working in an shared space were sometimes I want headphones to avoid annoying other people, but at other times speakers are OK. I want to be able to toggle quickly. In an ideal world, the solution to my question would work in Vista too.

• Change audio output depending on which one is on

  - by pkrish

  I have a PC that is hooked up to my HDTV (via a long hdmi cable) and to a monitor, which is in another room. I have speakers directly plugged to the PC audio out. The PC is next to the monitor and speakers. I am not sure but I think Windows can play sound on only 1 audio device at a time. And I can only set 1 device as the default output. I can get sound on the TV or speaker depending on which device I set to default. But I would have to do this every time I switch between using my TV or my monitor! Is there some way to configure such that sound plays through the TV if the TV is on, else it plays in the speakers? If this is not possible, then the next best alternative would be to get the sound to play on both the devices at the same time. Thanks!

• Audio input problem in Ubuntu 9.10

  - by Andrea Ambu

  My audio input is a mix of my mic output and my sound card output. I'd like it to be just my mic output. I was able to do so in Ubuntu 9.04 but the interface is 9.10 is totally changed and I tried every my creativity was able to think. It's really annoying when talking to other people over the internet because they keep hearing their voice back. I'm not sure I explained it in clear way so I'll give you an example: What I do: I put an mp3 on play or a video on youtube then open a recorder and start to talk on my mic. What happens: both my voice and audio from mp3/youtube get reordered, even if I put headphones volume to 0 (via hardware). What I'd like to happen: Only my voice should be recorded. I'm sure I'm missing some technical term, but that's the problem and I'd like to solve it in Ubuntu 9.10, any idea?

• 802.11n Audio Interference

  - by colithium

  Symptoms My audio is riddled with pops/crackles/glitches. Sometimes I swear the glitches sound exactly like the facebook messenger sound (best comparison I can give). Cause Using DPC Latency Checker, it reports the latency to be an abysmal 17,500µs (0.0175s). The first thing I did was disable my 802.11n wireless adapter. This immediately dropped the latency to a nice 250µs. When I re-enabled the adapter, it jumped right back up. I'm 99% certain that this is the cause of my audio glitches. Solution What can I do about it besides using wired Ethernet or buying a whole new adapter? My adapter is a Dell Wireless 1505 Draft 802.11n WLAN Mini-Card. To be honest, I've had nothing but trouble with the 802.11n standard and am contemplating just going back to g.

• How to generate a 8 bit per sample wav audio file in VLC

  - by Ahmed safan

  I'm using the following vlc command line to extract first 5 minutes of audio from video file "-I dummy -vvv --no-sout-video --sout-audio --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-transcode-threads=5 --sout-transcode-high-priority --sout-keep --sout #transcode{acodec=s16l,channels=1,samplerate=8000,ab=64}:std{mux=wav,access=file,dst="c:\dest.wav"} "c:\originalvideo.mpg" --start-time=0 --stop-time=300 vlc://quit"; if ab=64 =64 k bits per second and samples per second=8 k samples then bits per sample=64/8=8 bits per sample but the problem is that the output file always has samples of 16 bits per sample. I know that sample can contain bits from 8 , 16, 24 to 32 bits per sample. i want to get 8 bits per sample file how can this be done ?

• Can't find generic USB audio driver for a Samson COU1 USB microphone

  - by marcipollo

  I am unable to use a Samson USB CO1U microphone on a PC running XP, SP3. When I plug it into the USB port, Windows generates the sound indicating that it has found new hardware, and the green LED on the mic lights. But, it does not work, and the device manager reports that it cannot find a driver after searching. The same mic works on a Vista machine. Samson has no driver on their Web site, and insists that the generic audio driver in Windows should work. (http://www.samsontech.com/PRODUCTS/productpage.cfm?prodID=1810). I cannot find a generic USB audio driver at Microsoft.com. Can anyone help? Larry
