I want some help on streaming an audio content on Windows8.I have several URL's which i need to play.Not sure if there is any ready to use API for this or anything else.
Can anyone please help ?
Try this:
Combine this with this.
Basically you create an instance of the MediaElement class with a URI like Uri targetUri = new Uri(#"http://www.bing.com"); which points to your audio.
Since you mentioned "several URLs" you'll need to create some sort of "playlist" (which may just be a collection of URLs). You can subscribe to the MediaEnded event of the MediaElement to know when to go to the next track. You'll also want to subscribe to the MediaFailed event in case the network goes down, the audio file is deleted or the audio file is using an unsupported codec.
Finally, consider adding support for audio to continue running in the background even when your application is not focused. This thread should help.

Ok so this question is actually in two parts.
I coded a video filter for VLC and I would like to add a control to the Video Effects panel on the OS X UI. So far I've been able to link my plugin the the UI by hijacking one of the existing controls, but this isn't ideal.
Now, if I open up the Xcode project (I'm running Xcode 6.3.1) and try to open the VideoEffect.xib file, I get the following error:
I tried to google this but it sounds like the only alternative would be to play archaeologist and dig up an old copy of Xcode 3. Is there any other way to be able to open this file and edit it somehow? I tried to look at the XML code but if I started to change that I'd do more damage than good.
The second thing I'd like to do is sending back values from the effect module to the UI. At the moment (by hijacking one of the existing sliders), all I can do is read a value from the panel with
config_ChainParse(p_filter, FILTER_PREFIX, ppsz_filter_options, p_filter->p_cfg);
p_filter->p_sys->i_factor = var_CreateGetIntegerCommand(p_filter, FILTER_PREFIX "factor");
and then, inside the callback function:
p_sys->i_factor = VLC_CLIP( newval.i_int, 0, 255 );
However, I haven't been able to write back the value. I'd like the filter to set p_sys->i_factor to a random value at start. This works (using var_SetInteger()), but it isn't reflected in the position of the slider in the Video Effect panel. I suspect I need to hack a bit deeper for that. Any ideas?
Regarding your first question with the xib-file. Consider downloading and using our forthcoming 3.0 code from git://git.videolan.org/vlc.git - it allows editing of said file without Xcode 3.
Regarding your second question, why would you want your video filter to interfere with the UI? This is not how the architecture of VLC works and there is no correct way to do it at this point. You would need to edit the core to do another global variable callback to ask the UI to reload the presented filter configuration.
Perhaps, if you give details about what your filter does and what you want to achieve, we find a more supported way :)
I am making a game, so at one point I need to play two sounds at once, so I played the first one using the "My.Computer.Audio.Play()" Method to load from resources.
As for the second, I used Windows Media Player to load the second sound In A SPECIFIC FOLDER, now I know it is possible to extract files to a folder and program it to play from there to avoid trouble, but I don't want them to be extracted.
So I'm trying to get the file path from resources and put it in WMP's URL, but couldn't get any result after searching the internet.
Am I missing something?
And if you know any better alternative, make sure it can:
1- Replay sound (coding with timer is ok),
2- Change Sound Position
You can use the MediaPlayer class in code or MediaElement in XAML for playing audio files in a WPF application. Check out the article WPF Media Player In VB.NET for code samples.
I am receiving a stream through the RTCPeerConnection, but can't get it to work properly. Using the mediaStreamSource doesn't work (I read that there was a bug in chrome?). So I tried a workaround: using webkitURL.createObjectURL to put the stream in an audio object. This works, but not with 'mediaElementSource'. When I first create the mediaElementSource and then put a dataURL of a local file in the audio element's stream, it works like normal, but whenever I add the stream to the element, it starts playing normal (like when mediaElementSource has not been made, as if it is just a normal audio element without the AudioContext. When I then put another dataURL from a local file in the element, it directly plays through the AudioContext. Does anyone have any idea?
Edit: found the chrome issue.
Guess I will use canary then. Other solutions are welcome :)
edit2: sadly that doesn't work...
I am trying to build a site using video.js to view videos. We need to switch videos while maintaining the currentTime value from the old video. The way I have it working right now is using the loadedmetadata event to set currentTime. The problem I am seeing with this is that the first frame of the video gets shown momentarily while the player seeks to the right time. I am new to JS programming so perhaps I am doing something wrong but I do not see anything in the docs that can help me overcome this. I am trying to render H.264/mp4 videos in Chrome. Thanks!
Changing the preload setting to 'metadata' might help this in the browsers that support that setting.
preload="metadata"
Then it supposedly should only load the metadata and trigger the loadedmetadata event, and not show the first frame. That is unless providing any new src forces preloading, and I'm not sure off the top of my head.
HTML5 video doesn't give us a lot of options around seamless switching videos unfortunately. The media source API proposal from Google/Microsoft/Netflix aims to fix this. http://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html
You could try this:
https://bitbucket.org/felixschwarz/videojs-hdtoggle/
As seen here on the old videoJS-Forum I think you might have to declare preload="auto".
In the linked forum-threat there are also some changes I made documented.
Is it possible to capture a snapshot of a video that's loaded using the HTML5 video element and use that as a preview image until the video loads or the play event is triggered? I know about the poster attribute but I want the thumbnail to be self generated, like a random frame from the video. Sort of what YouTube/Vimeo does.
Thanks,
I don't think that this is possible in pure HTML5. Principally because the stream is not loaded when you see the 'object' in the webpage so the client can't get the desired frame.
However, the best option for you is to save / cache the 'random frame' before loading the page and then use it as the poster of the video. This will allow you to reduce the client work and save the bandwith.
check THIS, which is the first thing that I've found (if you're using PHP and you want a 'quick and dirty' way to get the frame)
Update
Apparently HERE there is a solution with popcorn.js BUT it seems that you can't do it in the way that (I suppose) you need.
This because it would be possible to do this only inside the same domain due to browser security issues.
