I am working on project which is generating videos using a player. Using the HTML tag <div id={renderId}> , when I render the div element with a dynamic ID then I see the video , in case I change to static value it doesnt render .I am not sure why it happens.. There is only 1 video on the page .
When the value of renderId is new Date().getTime() I see the video works fine on the page.
when I set it to abc or any fixed value, there is no video on the page.
This is a React application with Next.JS
When we use an HTML video tag with preload = "metadata", it automatically loads the thumbnail whether or not the poster attribute is present. I wish to make sure that the poster attribute value remains the permanent thumbnail without using preload = "none".
Is there a way to accomplish this?
Thank you in advance!
I have converted a flash animation using google swiffy. But how can a show a GIF image in case if browser does not supports google swiffy converted flash content ?
google swiffy uses html5 canvas, you can check if the html5 canvas is supported or not. Put the image in div so you can hide/unhide base on the checking.
I had a similar implementation in my project and this is how I do it.
var test_canvas = document.createElement("canvas");
var canvascheck = (test_canvas.getContext) ? true : false ;
if (canvascheck)
//show the swiffy here and hide the image div
else
//show the image div
I am using HTML5 file api on mobile web app for image uploading utility.
I am capturing image using camera and upload it to server.
Problem is that if I capture portrait image the uploaded image automatically converted to Landscape.
You'll need to transform the image to correct the orientation. Fortunately, the image should include EXIF data that you can use to do that. If you like, you can do this before the image is uploaded to your server:
Read the image's EXIF data
Use a canvas element to transform the image as appropriate
Export the canvas image into an image file
There's an excellent writeup, including code samples, in this blog post.
How to make image from Silverlight control with embedded html. Html was embedded with HtmlPage help. Currently in image i see empty space, where have to be html content. I know that html is rendered in absolute positioned div over silverlight plugin.
Image proxyImage = new Image();
proxyImage.Source = new
WriteableBitmap(Application.Current.RootVisual,
Application.Current.RootVisual.RenderTransform);
The clue is in your answer "over silverlight plugin". Silverlight does not have access to the image that the browser renders over the image. It can only see the surface that it is rendering.
