I want to create a TikTok-like video feed. I have videos stored in a CDN.
This problem requires caching features where you can cache e.g. the next 10 videos.
I have been searching for many resources but there does not seem to be a definite/clear solution process to this question. video_player seems pretty limited for this task. This Reddit post is the only one that tackles the problem up to a certain depth.
Hence, my question is a bit general: has anyone tried to tackle this problem and actually built a similar product? What would be the main steps to follow and what did you find the hardest to implement?
thanks.

Soo, I am working on my little game and I have been using LeanTween Engine for some UI elements. But there is a problem, I don't know all operations that I can use with LeanTween. So I am asking if there is any working article that could help me? I know that there was one article with information that I need but it is taken down from internet... Help pls. Much love.
As of writing, the official LeanTween API website appears to be down. Nevertheless, the web archive has a snapshot of the index page, which captures all of the available methods:
I want to make simple app that edit my virtual reality videos.How can i get started? I have some programming knowledge (C#, C++,Unity) I am looking for basic editing operations.For example changing background of the video,cropping video.
i did some research on Google but I have lots of questions in my mind.
What languages should I use?What SDK should I use?How can i do that?
The easiest way to get into this is to make a FFmpeg wrapper. It might not be the fastest API and will require lots of hacks to get around, but there is a reason why it's embedded in so many video editing utilities: it works.
You can go via two routes, the API or using the executable and piping in/out of it (C#'s System.Diagnostics.Process with pipes will work well). If you know shell concepts well, I'd suggest starting with the second one.
Word of advice, standalone operations will be easy with FFmpeg, but combining many of them is hard and often requires multiple passes with temporary files.
Edit: oh and about VR, it doesn't matter at this level. It would if you were to be stitching the video or making (but not applying) overlays.
Hi guys I'm looking for a solution to that enable a user compare a image to a previously store image. For example, i take a picture on my iPhone of a chair and then it will compare to a locally store image, if the similarity is reasonable then it confirms the image and calls another action.
Most solutions I've been able to find require cloud processing on third party servers(Visioniq, moodstocks, kooaba etc). Is this because the iPhone doesn't have sufficient processing power to complete this task?
A small reference library will be stored on the device and referenced when needed.
Users will be able to index their own pictures for recognition.
Is there any such solution that anyone has heard of? My searches have only shown cloud solutions from the above mentioned BaaS providers.
Any help will be much appreciated.

Try using OpenCV library in iOS
OpenCV
You can try using FlannBasedMatcher to match images. Documentation and code is available here You can see "Feature Matching FLANN" here.
I am just curious the question above. I try to google it but most of the tutorial appear with video support related topic. So i guess stackoverflow could possible ans my curiosity.
:)
Been looking around for this a little myself, and it seems to be an interesting but still up-and-coming topic around the web.
The most concrete example I found was here where they talk of a HTML5 Video Call experiment via WebKit-GTK.
Looking into it a bit further, the actual experiment details with some coding info can be found on Ericsson Labs page here. Maybe that'll give you something to go on.
There's also talk of HTML5 video calling coming to Facebook and all, though those are just rumors. To answer your question, if these few examples are solid, I guess that Video Calling on HTML5 seems possible, though in its very early stages perhaps.
I would like to download information from wikipedia to my iOS app. Firstly, I created simple RSS reader, but I can't download date from wiki. Now, I think that I should create parser for wiki.
What do you think about this? Any ideas?
Thanks,

In my opinion, parsing a website is never a good idea. Only the smallest change in the design of the website can break your application and make it unusable. I'd try to get to your data in an alternative way. ;-)

Scrapping a web site directly from your app is never a good idea. If you are ever going to do that it is suggested that you do it on a server and provide the data to your app in a well known format, so that site changes can be quickly managed by your server, and as a result, never breaking your app.
Although wikipedia does not have a formal API, it provides some other ways of extracting data from its servers. You should check this link:

I know this question is quite old. But I've dealt with the same problem and wrote this very small library. I am using the mediawiki api (Mentioned in the post from Felipe) to get the needed information.
