Did you got any solution? Will it be possible to get different quality options from .m3u8 file in IOS? — Uma Sankar Buddi, Sep 26 '18 at 09:46
After some research I came to a conclusion that In iOS , We can fetch audio, subtitles tracks from a .m3u8 video but not different quality options. Even if you know Quality Options, we can't able to select those options using AVPlayerItem. :( — Uma Sankar Buddi, Sep 27 '18 at 10:45
Hey @DivyeshGondaliya did you find the solution to extract the list of supportive resolution from the given m3u8 file? — Pushpendra, Sep 13 '22 at 06:09

var urlData: Data!
var savedString: String!

urlString = "https://xcxc.xxxxx.app/mobile/test.m3u8"

if let url = URL(string: urlString) {
                 urlData = try Data(contentsOf: url)
                 savedString = String(data: urlData, encoding: .utf8)
}

Yes, You can get the natural size of the video, if it is playing in the player. As you said that you're playing the URL in AVPlayer then use the following code to get the natural size of the playing track.

if let track = self.tampPlayer?.currentItem?.tracks.first {
        print("Size = \(track.assetTrack.naturalSize)")
}

No matter whatever the url is, if it's playing in player there will be the size for video defiantly.

To change the video quality, you've to create different urls for each bitrate like 144, 320, 480, 640, 720, 1080 etc. And have it on the player screen, whenever the user will change the bitrate you've to reload the player item with the url related to selected bitrate. – bestiosdeveloper Jun 14 '17 at 06:18
to change quality i have to set some list like 320,480,720 how to get this from url that is my point dear.....have some idea ??? – Divyesh Gondaliya Jun 14 '17 at 06:29
whoever is creating the urls for different bitrates your backend partner or any third party. They will provide you the different urls to their respective bitrates. – bestiosdeveloper Jun 14 '17 at 07:43
