Could you support parsing M3U8PlaylistModel into .m3u8 files?

[wangleiTT]

After parsing the .m3u8 file into M3U8PlaylistModel, I tried to modify the details of the model. But I need to convert it to the original .m3u8 file URL and use it as the AVPlayerItem of AVPlayer. So, is there any way to serialize M3U8PlaylistModel to original .m3u8 file?

M3U8Parser is the best HLS parser kit I'v seen. Any answers are helpful, thank you.

Try savePlaylistsToPath:(NSString *)path error:(NSError **)error

Can you provide a way to serialize directly to memory instead of hard disk sandboxing? If I have to read from the sandbox path to memory every time, the efficiency of I/O will be greatly affected. ^ ^

Serializing M3U8 string is not perfect right now. Something is missing (x-key, byte-range, etc.)

You can try m3u8PlainString (m3u8PlanString is wrong spelling in 0.5.0. Will be fixed in next version) for MasterPlaylist. 😳

I have tried m3u8PlainString and found some issues in the result. Here's my snapshot, hope it can help you.

Could you provide a demo?
Unit test case is fine.

CODECS parsing bug has been found.🤕 but URI

The demo is very simple, here's my codes:

import UIKit
import M3U8Kit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        
        DispatchQueue.global().async {
            do {
                let url = URL(string: "https://ks3-cn-beijing.ksyun.com/xpc-test/5de9c696f1e39_dash_hls_playlist.m3u8")!
                let origin = try String(contentsOf: url, encoding: .utf8)
                print(origin)
                
                let m3u8 = try M3U8PlaylistModel(url: url)
                let parsed = m3u8.masterPlaylist.m3u8PlanString()
                print(parsed!)
            } catch let error {
                debugPrint(error)
            }
        }
    }
}

Anything I can help, just reply.😄

#EXT-X-MEDIA:TYPE=AUDIO,LANGUAGE="eng",NAME="audio_id_6",DEFAULT=YES,GROUP-ID="audio_group", URI="audio_6.m3u8"

Spaceholder has been found before URI.🙄 It may not be used in M3U8 file.

[wangleiTT]

Good catch! But will you make some compatibility improvements?

[wolfcon]

M3U8 File shouldn't appear that extra spaceholder.
Trimming method has been added.😳 You shouldn't rely on that🤣

Already updated to 1.0.0, brilliant fix! 👏🏻👏🏻👏🏻
