[when I am on slow internet connectivity or images are of larger size comes from server and taking time to load]
Images taking time to load, so animation starts playing even if images are not loaded yet, to overcome this I have used preloader.
Now problem is audio I have used on this page loads early and starts playing even if page still showing preloader.
So it doesnt seem to work
Que1:
for images I have noticed until all assets are ready, edge min file attaches style
.edgeLoad-EDGE-137360589 { visibility:hidden; }
so for certain time it shows white screen as all other things it making hidden but animation runs in background, which doesnt look good.
Que2:
To resolve above issue, I tried preloader. By using it I can resolve above issue but it creates problem with audio.
Even if preloader is there, my audio starts playing in background.
[audio preload is set to false, but as and when it loads it starts playing not waiting for preloader to complete]

I'm trying to get a 360 streamed video to play at its full (4k) resolution. I did do previous searching and found the below thread but it didn't answer my question.
How do I adjust the video resolution?
My end goal is to integrate this into vlc unity but I also don't see how to adjust the resolution up to 4k (or higher) for streamed videos even on the desktop app. As a test, I tried a 4k video from youtube in the VLC desktop app and couldn't see how to get it to play in 4k. The end goal is to stream from aws but I want to confirm that my stream can indeed play at 4k before continuing to try to figure out why it's playing at lower resolution within Unity. It resizes down to 1920x1080 instead of the intended 4096x2048 for my aws stream and resizes the youtube video down to 1280x720 from its 3840x2160.
I've tried messing with the advanced settings and looking at input/codecs and the best option for "preferred video resolution" is "best available" (below that is full hd). I've looked through other suggestions online and didn't see a lot to change but did change Settings-->Video-->Output to "DirectX (DirectDraw) video output. This one was just me fumbling through the desktop app, but I tried going through Media-->Open Network Stream, clicking the arrow next to play and selecting stream, choosing RTSP for destination, and then editing the resolution within the profile to be a specified width and height. None of the above changed the resolution of the video.
TL;DR - How can I play a streamed video at higher resolutions (4k and up) in the VLC desktop app and in VLC Unity?
Edit - adding requested code snippets. This just modifies the UseRenderingPlugin file from the VLC unity asset.
Also, similar to what was getting discussed in the comments, when I play the video locally instead of streaming, it plays at the full resolution of the video.
Within Awake() I set the material to the 4096x2048 one mentioned for the skybox
RenderSettings.skybox = material4k;
And then in Update here is the relevant segment
var texptr = _mediaPlayer.GetTexture(out bool updated);
if (updated && texptr != IntPtr.Zero)
{
Debug.Log("Creating texture ");
tex = Texture2D.CreateExternalTexture((int)width,
(int)height,
TextureFormat.RGBA32,
false,
true,
texptr);
RenderSettings.skybox.mainTexture = tex;
}
I want to play a sound from a Chrome Extension, but I read that Content Scripts cannot play sounds. So I put this code in my background script:
var audio = new Audio("alert.ogg");
audio.play();
but still no sound. From the Console of the _generated_backgound_page.html I was able to inspect the Network tab and see that the sound file is loaded successfully, but I hear nothing.
Also, in another HTML page, I could load another Javascript, which has the above code, and it works (I can hear the sound.)
The fact that it is in the background script seems to have made it fail. Also, note that I do not have a background PAGE associated with the background SCRIPT. Does that matter？
edit: problem solved. The above code works but I forgot to listen to the right sound output channel.
You can generate the background page with javascript. I think the sound must be in a html page to be loaded and played.
This should work:

I used a base64 audio file but you can use a normal file too.
I have a problem using MediaRecorder to record video with ActionBar Sherlock. I have a base app that sets up and records video files without any problem, but as soon as I add ABS, it stops working.
Right now I have a non-ABS app that can record video with no problems at all and the same app (in all other respects) with ABS that doesnt work.
Initialising the video recorder using the CAMCORDER settings gets through the MediaRecorder setup OK, but when I stop recording, I get a '-1' error in the logcat and the resulting .MP4 file has no audio or video track (although the file size looks OK).
If I try setting MediaRecorder with maunaul setups (i.e., format, frame rate, size etc), the setup keeps falling over at 'setVideoSource...CAMERA'.
Does anyone know if there's any reason why ABS would upset MediaRecorder this way?
Added 01/01/13:The application I'm working on is being upgraded from a photo-taking app to a video-recording app. The preview for the camera was previously done with a ImageView frame, which works OK for providing an image preview, but not for use as the video preview on MediaRecorder. For MediaRecorder, I needed to use a SurfaceView. Once I switched to a SurfaceView, all was good!
I have an HTML/JS app running in a webview in an iPad app. The app uses the HTML5 video tag. Videos work fine in iOS4.3 but today I've tested on iOS5 and the videos simply do not show up.
I have verified that it is not a layout related issue by setting background color and borders on the video element.
The same behaviour is evident irrespective of whether the app is run directly in mobile safari /from the home screen or within the webview.
The template for the video is simply:
<video controls src='{url}'></video> //where {url} is substituted at runtime.
The relevant video url plays correctly directly in the mobile Safari on iOS5.
I have tried to proxy the app comms and it seems that it does start loading the video but then stops, no video controls show and only the background color I have set shows thru.
Any ideas would be greatly appreciated. Thanks.
Have you tried create an empty webview, without additional parameters and scripts and make sure that you call it only once? I had the same issue when i call it twice without clearing previously created one - just audio was played.
Try to look at http://blog.millermedeiros.com/2011/03/html5-video-issues-on-the-ipad-and-how-to-solve-them/ and see if the fix works for you...
he he - should have read the fine print - did not notice you had answered yourself - remember to tick the thread off as answered
I've fixed this in code by changing the width and height by a pixel once the video element is created. Must invoke a repaint or something to that effect
I want to have huge background images on my site but without giving the user a hard time downloading them and the site looking ugly as the background loads.
They would be no bigger than 1920 X 1080 in size, however it's hard to say in terms of kilobytes/megabytes.
What are my options here and which are most effective?
I'm not too bothered about bandwidth, just want to user to think everything looks nice ;)
One option is to use multiple backgrounds. Have small background as bottom layer and cover it with larger background.
It might be tricky to have two backgrounds if you want it on body and want to support IE. Solution might be to start smaller body background use JS to change low-res background to high-res once it loads:
var i = new Image();
i.onload = function(){document.body.style.backgroundImage = 'url(' + i.src + ')';}
i.src = 'gigantic.jpg';
Keep in mind that such large background needs more RAM than some mobile browsers have (iPhones pre-3GS will either refuse to decode such image at all or will start purging cache/tab content in panic).
The latter problem can be worked around with CSS Media Queries:

Except query max-device-width instead of (virtual/zoomed) max-width.
