kandi X-RAY | vidi Summary
The browser world is highly fragmented, and browser vendors all have their own preferences and priorities regarding video encoding standards and adaptive streaming methods. This results in a lack of compatiblity between browsers, with each browser supporting some methods while providing no support for other methods. vidi makes it easy dealing with otherwise complex playback scenarios.

This gets the result you want (dbfiddle on db-fiddle.com, which offers MySQL 8.)

QUESTION
So I have this practice app I'm working on, the issue is that when I click 'add to cart' button for the same List Tile item, it shows error on the 'Cart' page. I understand why that is, the list doesn't allow the same item in it, and it says that each item should have unique ID, somebody know how to do that easily? Each of the code blocks is on a separate page.
Here is the cart model code, the provider function that adds the items to cart:
...ANSWER
Answered 2020-Nov-26 at 15:18Well because of the stupid reputation system I cannot add a comment, but it seems like you are adding the item to a new list which looks at the unique ID's .. since those need to be unique, it gives an error when you add another item that has the same ID. Without more code to go on, that's where it's going wrong.
You can probably fix that by giving each item you enter into the new list a unique key. Instead of taking the key from the item you want to add. Or make a small adjustment to the existing key from the item you want to add, while adding them. To make sure the keys can never be the same.
QUESTION
I am attempting to use JavaScript to change the currentTime property of a video element. The property assignment is pretty simple and works. I am also listening for seek changes by the video. My problem is that whenever the currentTime property is assigned programmatically, both the onseeking and onseeked methods are called. My reason for listening for the seeks is to capture ONLY seek events generated by the user and not the code. Similar code to what I've tried so far is as follows:
...ANSWER
Answered 2020-Mar-31 at 04:21If you carefully alter and change video.onseeking
and video.onseeked
at the right time, you can distinguish user seeks/seeked vs programmatically-generated seeking/seeked (which I've simulated with the do_non_user_seek()
function below).
The general idea is that when doing a non-user seek, first set video.seeked
to point to a function non_user_seeked()
which gets called automatically at the completion of the non-user seek, at which point it sets video.onseeking
and video.onseeked
back to their original user_seeking()
and user_seeked()
values.
You now have several functions which get called depending on whether the seek was user-invoked, and can distinguish between them accordingly. See the console.log()
results for details of which gets called when.
QUESTION
We have an instance that uses cloudinit for initial instantiation, and this instance and cloudinit work great.
We want to add swap to this instance, and have correctly configured a suitable disk, however we cannot figure out how to get cloudinit to initialise the swap disks, like cloudinit does with all the other disks on the machine.
Our configuration of our disks, including swap, is as follows:

Answered 2020-Feb-07 at 22:52In response to "What addditional steps are required for cloudinit to 'mkswap' and 'swapon' the /dev/xvdg disk?", the short answer is "nothing".
The longer answer is that you need to be running a version of cloud-init with the following bugfix applied:

I am doing a homework exercise which is to color the background of my paragraphs randomly by clicking on them. The thing is, when I tried my code, I receive an Uncaught Error " Cannot Read property 'style' of undefined. I tried to break my head but I really don´t understand what I am doing wrong. Can you help me?
Thanks in advance.
...ANSWER
Answered 2019-Mar-25 at 15:03In the click listener function your element is reachable by "this".
Otherwise you color function was not called because you forgot the "()" and return the result in the function. The aboce snippet yould work. Is this what you'r loocking for ?
