Read ID3 tags generated using Apple's id3taggenerator
9 octobre 2024, par Damiaan DufauxHi I am creating an HLS stream with ID3 tags using Apple's HTTP Live Streaming (HLS) Tools, FFmpeg and NodeJS. When I try to read out the stream using an
AVPlayerandAVPlayerItemMetadataOutputon macOS I'm not able to read out the ID3 tags. When I use the same code to read out a sample stream containing ID3 tags I do see them popping up. What am I doing wrong ?

Reproduction :


Streaming


I generate an infinite HLS stream from a 5 minute long mpeg ts file using this command :


ffmpeg -stream_loop -1 -re -i 5m.ts -c:v copy -c:a copy -f mpegts -strict -2 - | mediastreamsegmenter -b http://DamiaanTheoPro14.local:8081/ -f /tmp/hlsId3/video -D -m -M 50000 -log /tmp/hlsId3/log.txt


I serve that HLS stream using nodejs builtin
http-server

ID3 tag generation


Then I emit some ID3 tags using the following commands :


id3taggenerator -title foo -artist bar -a localhost:50000
id3taggenerator -text "foo bar" -d "sample text" -r -a localhost:50000


Reading


Now to read out the tags I use this little SwiftUI app :


import SwiftUI
import AVKit

let bipbopUrl = URL(string: "https://devstreaming-cdn.apple.com/videos/streaming/examples/bipbop_16x9/bipbop_16x9_variant.m3u8")!
let localUrl = URL(string: "http://damiaantheopro14.local:8081/prog_index.m3u8")!
let local = AVPlayerItem(url: localUrl)
let bipbop = AVPlayerItem(url: bipbopUrl)

struct ContentView: View {
 let player = AVPlayer()
 let observer = Id3Observer()
 var lastTag: AVMetadataGroup?
 
 var body: some View {
 VStack {
 HStack {
 Button("BipBop") {
 player.replaceCurrentItem(with: bipbop)
 bipbop.add(observer.metadataOutput)
 }
 Button("Local") {
 player.replaceCurrentItem(with: local)
 local.add(observer.metadataOutput)
 }
 Button("🅧") {
 player.replaceCurrentItem(with: nil)
 }
 }
 VideoPlayer(player: player)
 }
 .padding()
 }
}

class Id3Observer: NSObject, AVPlayerItemMetadataOutputPushDelegate {
 let metadataOutput = AVPlayerItemMetadataOutput()
 
 override init() {
 super.init()
 metadataOutput.setDelegate(self, queue: .global())
 }
 
 func metadataOutput(_ output: AVPlayerItemMetadataOutput, didOutputTimedMetadataGroups groups: [AVTimedMetadataGroup], from: AVPlayerItemTrack?) {
 print("metadataOutput", groups.count)
 print("\t", groups.map { group in
 group.items.map { item in
 "\(item.dataType) \(item.keySpace!) \(item.key!) \(item.time.seconds) \(item.duration.seconds.rounded())"
 }.joined(separator: "/n/t")
 }.joined(separator: "\n\t"))
 }
}

FFMPEG on AWS Lambda Only outputs half a second of video when converting video from mobile safari
18 août 2023, par user1825257I am running FFMPEG on AWS Lambda using nodejs and fluent-ffmpeg. I am able to convert videos recorded on most devices / browsers, but when I attempt to convert videos recorded on Mobile Safari, the length of the output video is 1/2 a second regardless of the input length.


My Typescript code is :


import * as ffmpeg from 'fluent-ffmpeg';
 public static StandardizeVideoFormat(
 inputSignedUrl: string,
 filename: string,
 ): Promise<string> {
 const localFilePath = `/tmp/${Date.now()}_${filename}.mp4`;
 
 return new Promise((resolve, reject) => {
 ffmpeg(inputSignedUrl)
 .outputOptions([
 '-crf',
 '18',
 '-vcodec',
 'libx264',
 '-codec:a',
 'aac',
 '-preset',
 'medium',
 ])
 .output(localFilePath)
 .on('start', function (commandLine) {
 console.log('Spawned Ffmpeg with command: ' + commandLine);
 })
 .on('error', function (err) {
 reject(err);
 })
 .on('progress', function (progress) {
 console.log('progress', progress);
 })
 .on('end', function () {
 resolve(localFilePath);
 })
 .run();
 });
 }
</string>

Using FFprobe, The metadata of the input file is :

Any ideas on why the output of my command on this file always results in a 0.5 second long output ?
