I can try to understand a video platform but I didn't understand a point. How does the platform know the minute and the second we stayed after we watched anything video or during we watch anything video ? How does the platform manage status like offline status ?
What is the logic this ?

I have been looking around online for an answer for some days now, without any luck. So now, I hope one of you might be able to help point me in the right direction.
WHAT I AM TRYING TO DO:
I want to build a C# application where I can apply different types of distortion and pitching effects to all types of audio that comes out of a preselected audio endpoint.
It should not matter if the user is playing an audio stream or an audio file on their system. I want to apply effects to it before the audio leves the selected endpoint.
I have been trying to use some of the windows audio APIs like 'DirectSound' and 'WASAPI' and also the open source project NAudio. sadly all with no luck so far.
WHAT I AM STRUGGLING WITH:
I can't seem to figure out what windows API I should use or if I would have to make my own audio API that takes directly with the windows Audio engine: https://learn.microsoft.com/en-us/windows-hardware/drivers/audio/windows-audio-architecture
Please let me know your thoughts, or if you think I am looking at this all wrong.
Simpler solution: It should be possible in a soundcard driver if it can load effects.. SB live successors or EMU based cards are the cheapest and KXproject driver is awesome for those
I've built a webapp to host low-res proxies of our teams video files. The webapp is primarily for tagging and searching video. Additionally, I'd like to be able to play a random playlist of clips on TVs around the office. I've implemented this by "Casting Tab" to a Chromecast, and it works fine.
However, now I'm running up against the bandwidth limitations of my host. Latency and everything is fine, but to run a single TV's 2.5Mbps stream 8hrs a day for 23 days a month comes to about 207 GB/month, 20% of my alotted 1TB monthly transfer.
How can i build something that will "cache" these clips client-side, so that it doesnt re-download them unnecessarily? There are about 1000 clips. I'd prefer to keep it connected to my webapp via browser or some API endpoint so the RAND() stream of clips is constantly updated as people add to it.
Note: I asked a related question yesterday, and it seemed to fix my specific issue, but it doesn't seem to have worked at scale, so I'm broadening the approach a bit. Browser Caching of images and videos served via php query strings
Shaka Player has built-in support for offline playback, along with a pretty good API for listing offline assets, and removing them again.
This would require that you have your videos in MPEG-DASH format. Luckily Google also has a tool available for that. Shaka Packager can take your mp4's and package them for MPEG-DASH, provided the MP4's follow some simple requirements.
You could probably build something yourself using similar mechanisms to the Shaka Player, but it seems much easier to use Shaka for doing it.
I want to add Live Video streaming (IP Camera set up) in Xamarin Forms. I have found link click here but I don't know how to implement this in Xamarin forms or any other option for implement live video streaming in xamarin forms anyone, please help me.
Check out https://github.com/videolan/libvlcsharp.
It supports playing RTSP out of the box.
First of all, you likely want to convert the IP camera stream to something else. RTSP is going to be a pain to get working cross platform, and i don't know of any library that handles that nicely for Xamarin. RTSP is also hard to get working well across networks with Firewall, NAT etc.
You can convert the RTSP stream to HLS, and have a much easier time. Conversion to HLS has a number of solutions, from hacking something together with ffmpeg to a more streamlined solution like Wowza.
Once the stream is HLS, you should be able to get it working with something like Xamarin Media Manager without too much trouble.
We have developed an application which is able to download an play the video in offline mode.But as the size of the video is much larger it is not possible for us to make the user wait for long to get video downloaded and play.So we would like to implement progressive download while playing the video but would also like to save the video locally for playing it locally too. Is there any way or any possibility of caching the video in offline mode ? Also can we implement any functionality where in a part of video played or buffered is saved locally and played in offline mode. Also can we make the buffering start or resume from the point where it was stopped when user is online ? Any Suggestions would be helpful.
Thanks.
I think you would need to download the video using FileTransfer.download() independently of playing it. Then you could cache the video on the filesystem and play it offline if the user wanted to watch it again.
My question is similar to this question. I want to capture and modify video stream from web camera in Windows transparently to all applications using web camera. Whether should it be some kind of driver? Is it possible? Is there API for such tasks? I'm reading about DirectShow filters. Am I on the right direction?
Thanks for your help!
You can use DirectShow to capture the video stream from the camera, modify it, and then pass it on to either a DirectShow source filter (will be seen by some apps as "webcam") or to a kernel driver (will be seen by pretty much every app). If you're new to this do realize this is a lot of work. Depending on what you want to do, consider buying ready made components for your developing environment or even complete applications that can do this (I developed one).
