How to get wifi or 3G internet speed programmatically in ios - ios

I need a custom video player which play based on internet speed and I have four video urls which is hd,high,medium and low quality here what I am doing is I am playing high resolution video when internet speed with certain limit and something like fast and want to play based on wifi or 3G speed and here the problem is I am not able to get internet speed. I searched lot of sites for this. and one more point is while playing I have to check internet spped for every 10 secs.

Assuming you are using AVFoundation for video playback, an easier solution to your problem is rather than creating four video files, convert the video for use with HTTP Live Streaming, which allows the player select the most appropriate bitrate media stream.

Fast video stream start

I am building an app that streams video content, something like TikTok. So you can swipe videos in table, and when new cell becomes visible the video starts playing. And it works great, except when you compare it to TikTok or Instagram or ect. My video starts streaming pretty fast but not always, it is very sensible to network quality, and sometimes even when network is great it still buffering too long. When comparing to TikTok, Instagram ... in same conditions they don't seam to have that problem. I am using JWPlayer as video hosting service, and AVPlayer as player. I am also doing async preload of assets before assigning them to PlayerItem. So my question is what else can I do to speed up video start. Do I need to do some special video preparations before uploading it to streaming service. (also I stream m3U8 files). Is there some set of presets that enables optimum streaming quality and start speed. Thanks in advance.
So theres a few things you can do.
HLS is apples preferred method of streaming to an apple device. So try to get that as much as possible for iOS devices.
The best practices when it comes to mobile streaming is offering multiple resolutions. The trick is to start with the lowest resolution available to get the video started. Then switch to a higher resolution once the speed is determined to be capable of higher resolutions. Generally this can be done quickly that the user doesn't really notice. YouTube is the best example of this tactic. HLS automatically does this, not sure about m3U8.
Assuming you are offering a UICollectionView or UITableView, try to start low resolution streams of every video on the screen in the background every time the scrolling stops. Not only does this allow you to do some cool preview stuff based off the buffer but when they click on it the video is already established. If thats too slow try just the middle video.
Edit the video in the background before upload to only be at the max resolution you expected it to be played at. There is no 4k resolution screen resolutions on any iOS device and probably never will be so cut down the amount of data.
Without getting more specifics this is all I got for now. Hope I understood your question correctly. Good luck!

iOS AVPlayer too slow when streaming online video

I'm using AVPlayer to play online video content. Server supports byte ranges as according to RFC 2616.
Thing is that it takes too long for AVPlayer to have playable status.
For a 1GB video (duration = 1h 45min) it takes 1min-2min to start playback. I notice that seek works rather good after that.
Playing same video on default Android media player takes 15sec to start.
It seems as if AVPlayer downloads chunks in different parts of media space for better seek support. But I want video to start as soon as possible. Is such a thing possible - to configure AVPlayer for quicker play?

Youtube api and Samsung SmartTV App resolutions

im working on Smart TV app for Samsung which should use youtube api to play videos. Embedded videos will work only when app resolution and yt player size are 960x540 or below,
if I set higher resolution (1280x720 or 1920x1080) player stucks, behaves really slow, and videos will buffer infinitely.
Has anyone succeeded in embedding yt videos with higher resolution player?
Thx in advance.
Video player work in FullHD resolution in fullscreen regardless of widget resolution.
If you have troubles with buffering, check your connection speed. Try play file from local network to check that selected resolution and codecs hadled well by TV.
recently i found this case. The youtube apps working great on 720p resolution if the video length is below 10min, but longer than that for example 30min the player will stuck just like as you said.
When changing the app resolution to 540p the youtube player working great again for all videos. I suppose the youtube is using progressive download on their player and Smart TV storage itself is not enough to prepare the long video storage space with 720p resolution rendering.
The conclusion is when using flash player/youtube in apps the best at using 540p app resolution.
Thx all for answering,
in the end I used different approach which showed like best solution.
I used 720p resolution, and youtube cue video functionality.
Basically i cued video, and on "videoCued" event i called "playVideo" method.
This allowed player to get ready and initialize before playing video.

Increase video buffer for HLS (Apple HTTP Live Stream), possible?

We're using Wowza 3.5 in our server to stream videos, and JW Player for the player.
The streaming of videos are working fine when viewed in iPhone and iPad.
What we are trying to do now is, when a video is playing on an iOS device and a user paused it we would like the video to buffer (download) while it is paused so even if the user lost connection to the internet he could still watch the video until. Currently it is only buffering for 30 seconds to 1 minute.
How could we increase this buffer time to possibly buffer / download the whole video while the player is paused?
Is this even possible in HLS?
This is not possible when you're playing a video using HLS in a webpage using the default browser.
You need to create your own app to control the video buffer when playing videos using HLS.
There is an App with Wowza called nDVR, you can pause, play and record using nDVR. Also I think you can increase the buffer length in application.xml, make sure.

IOS - Live streaming using MPMoviePlayerController losing video but not audio

I am Streaming a live video (.m3u8) with MPMoviePlayerViewController, however during playback sometimes the video is lost and only the Quicktime logo is displayed, however the audio still goes on.
This happens at random times, sometimes never, maybe when the internet is not as strong as it needs, but console doesn't log any errors or changes in the playback.
Is there a way to notice when this happens and to recover the video image from the streaming?
This is how HTTP live streaming is designed to work. It will progressively choose higher or lower quality streams based on the strength of the internet connection. If the connection is not fast enough the "last resort" is to continue to play audio but no video. The only way to recover the video image in this case is to improve the speed of the internet connection.
