I'm streaming video from URL stored in firebase storage and I'm using the following code for streaming the video using ExoPlayer
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelector trackSelector = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory(bandwidthMeter));
LoadControl loadControl = new CustomLoadControl();
exoPlayer = ExoPlayerFactory.newSimpleInstance(SafetyTVHomeActivity.this, trackSelector, loadControl);
Uri videoUri = Uri.parse(videourl);
DefaultHttpDataSourceFactory dataSourceFactory = new DefaultHttpDataSourceFactory("exoplayer_video");
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
MediaSource mediaSource = new ExtractorMediaSource(videoUri, dataSourceFactory, extractorsFactory, null, null);
exoPlayerView.setPlayer(exoPlayer);
exoPlayer.addListener(new PlayerEventListener());
exoPlayer.prepare(mediaSource, false, false);
exoPlayer.seekTo(0, 0);
Everything is fine and the video gets streamed. But the problem I'm facing is the initial load time to start the video is too long (5+ seconds). I want to reduce the initial loading time to start the video to (0-2 seconds). Is there a way to achieve this using exoplayer?
I also tried using DASH media source in exoplayer using the code below
Uri videoUri = Uri.parse(videourl);
DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory(Util.getUserAgent(SafetyTVHomeActivity.this, "app-name"));
MediaSource mediaSource = new DashMediaSource.Factory(dataSourceFactory).createMediaSource(videoUri);
exoPlayer = ExoPlayerFactory.newSimpleInstance(this);
exoPlayer.prepare(mediaSource);
exoPlayerView.setPlayer(exoPlayer);
exoPlayer.addListener(new PlayerEventListener());
I used the same firebase storage URL in the dash media source but I'm getting the following error
ExoPlayerImplInternal: Source error.
com.google.android.exoplayer2.ParserException: org.xmlpull.v1.XmlPullParserException: Unexpected token (position:TEXT G#��B�%���������...#2:79 in java.io.InputStreamReader#c587547) at com.google.android.exoplayer2.source.dash.manifest.DashManifestParser.parse(DashManifestParser.java:105) at........
Could anyone please help me on how can I work around this.
My main objective is to stream video from URL and the initial load time to start the video should be 0-2 seconds (The way TikTok does it). Any help would be really helpful.

I am trying to use multiple files with ffmpeg and I am having a problem with the duration of the files created through iOS devices.
I am recording the videos through the webcam of the device with:
mediaRecorder.current = new MediaRecorder(videoPlayer.current.srcObject);
mediaRecorder.current.start();
mediaRecorder.current.ondataavailable = (e) => {
setVideoCreatedData(e.data);
};
Then I am downloading the file to my computer and testing the metadata through https://www.metadata2go.com/ and this is the output:
As you can see, the duration is 0s.
I want to then use this file with ffmpeg, however, it does not detect the duration and therefore I am experiencing problems.
How should I record the video in order to get a proper duration on the file's metadata?
I'm trying to play a video from an app using Flash Builder 4.7, AIRSDK 31.0 and ios 12.
private function init():void{
holder.addChild(video);
this.addElement(holder);
nc.connect(null);
ns = new NetStream(nc);
ns.client = {};
ns.client.onMetaData = ns_onMetaData;
ns.client.onCuePoint = ns_onCuePoint;
video.attachNetStream(ns);
ns.play("Videos/video.mp4");
ns.addEventListener(NetStatusEvent.NET_STATUS, statusNet);
}
This works on simulators and on android devices, but not for ios devices. I've seen a couple of similiar questions but they are trying to stream an mp4 from a "http" address where mine is using a local file.
I've been asked to stick to mp4 format, although I have read using an FLV file should work.
Special considerations for H.264 video in AIR 3.0 for iOS
For H.264 video, the iOS APIs for video playback accept only a URL to a file or stream. You cannot pass in a buffer of H264 video data to be decoded.
So do I need to find a new way of playing the video other than netStream or am I best to swap to a different file type?
As a side note Adobe says to write your mp4 URLs like this:
("mp4:samples/myvideo.mp4");
My app can't find the file with "mp4:" at the front of the URL.
If you are wanting to play videos that are packaged with your iOS app it's important to ensure you are actually including them when you compile your app.
Untested but something like this should work.
var _dFile:File;
var _ns:NetStream;
var _nc:NetConnection;
var _customClient:Object;
var _video:Video;
_customClient = new Object();
_customClient.onMetaData = metaDataHandler;
_nc = new NetConnection();
_nc.connect(null);
_ns = new NetStream(_nc);
_ns.client = _customClient;
//this is the important bit for finding files within the .ipa bundle.
_dFile = File.applicationStorageDirectory.resolvePath("nameOfYourVideoDirectory/nameOfVideo.mp4");
_ns.play(_dFile.url);
_video = new Video(480, 340);
_video.attachNetStream(_ns);
_ns.addEventListener(NetStatusEvent.NET_STATUS, onNSComplete, false, 0, true);
private function metaDataHandler(infoObject:Object):void {
trace("Length of video",infoObject.duration);
}
private function onNSComplete(e:NetStatusEvent):void{
if(e.info.code == "NetStream.Buffer.Empty") {
//do something
}
}
However, I would highly recommend using an ANE to play video on mobile via the native media player. Take a look at Distriqt MediaPlayer ANE.
I'm developing an HTML5 audio player for use specifically on iPhones, and am trying to get an EQ visualizer working. From what I've found there are two ways to set this up:
One where you load the mp3 file on demand using an XMLHttpRequest:
var request = new XMLHttpRequest();
request.open('GET', 'sampler.mp3', true);
request.responseType = 'arraybuffer';
request.addEventListener('load', bufferSound, false);
request.send();
function bufferSound(event) {
var request = event.target;
var buffer = myAudioContext.createBuffer(request.response, false);
source = myAudioContext.createBufferSource();
source.buffer = buffer;
}
You then use the source.noteOn and source.noteOff functions to play and pause the audio. Working this way, I AM able to get the EQ visualization going. BUT, you have to wait until the mp3 file completely loads to start playing, which won't work in our situation.
The other way to do this is to have an <audio> element already on the page, and you get the audio data from that using:
source = myAudioContext.createMediaElementSource(document.querySelector('audio'));
You then use the audio tag's play and pause functions. This solves the loading problem as it allows the media to be played immediately once the page loads... BUT, EQ visualization is gone.
Both methods show the EQ when testing on Chrome (WIN), so there seems to be something specific with iOS/iPhone that isn't allowing me to get the data from an <audio> tag, but will allow me to get it if I load the mp3 file on demand.
...
Any ideas out there?
Unfortunately Safari doesn't properly support MediaElementSource. It's a bug: Why aren't Safari or Firefox able to process audio data from MediaElementSource?
I'm developing a radio app for BB 5.0 in java. I don't find a way to play the radio from the url stream address that I have. I use multiple formats but nothing works (.pls, .aac, .m3u). I get a RuntimeException every time I try to play the stream. The content is ok, I've checked it.
InputStream stream = Connector.openInputStream(urlPlay);
StreamConnection streamConnection = (StreamConnection) Connector.open(urlPlay, Connector.READ);
InputStream readAhead = streamConnection.openDataInputStream();
byte[] audioData = new byte[500];
readAhead.read(audioData,0,audioData.length);
ByteArrayInputStream in2 = new ByteArrayInputStream(audioData);
player = javax.microedition.media.Manager.createPlayer(in2, "audio/aac");
System.out.println("REALIZE");
player.realize();
System.out.println("PREFETCH");
player.prefetch();
System.out.println("START");
player.start();
Edit:
When I use a URL from my .pls file I hear a little bit of my streaming but It stops immediately.
I suspect the problem is that you are trying to play playlist files instead of an actual stream. Generally, you need to parse those files yourself to get the real stream URLs.
If you open up that .m3u file, you will see that it is just a list of URLs. Take one of those URLs and then try it. Also, be sure you are setting the right content type. You can determine what that type is with cURL or VLC.
I can play a video from the local file system, but can't get it to play from an external URL. No error message. Just a blank dark screen. Any ideas?
var movieFile = NSUrl.FromString("http://apps.focusonsound.com/demo/AppleVideos/Xylophone.mp4");
mp = new MPMoviePlayerController(movieFile);
mp.AllowsAirPlay = false;
this.View.AddSubview(mp.View);
mp.SetFullscreen(true, true);
mp.ShouldAutoplay = true;
mp.PrepareToPlay();
mp.Play();
Your code works - but only when I replace your URL with one where a .mp4 file can be downloaded (e.g. using Safari).
Could your URL simply be dead / outdated ?
