I'm having some cross-browser compatibility joys. I have a Ruby WEBrick server with a couple of servlets, one of which is used to stream media (Ogg and MP3). The servlet gets a couple of query parameters (a base64 urlsafe string key, a small string user, and a small number, sid). When I put the URL verbatim into Chrome, I get the QuickTime extension, and it works. When I post the same into FireFox, I get the expected unsupported codec. When I put it in Safari, it works. However, the URL is not being accessed directly. I have a jQuery Mobile app that uses the Javascript Buzz library, and uses these servlet streaming URLs as sources. The code works in Safari, allowing me to play the sounds. On FireFox, instead of falling back onto Ogg, it gives unsupported errors, and on Chrome, it does nothing. Here's the code that serves the MP3:
res.status = 200
str = File.new("Music/#{req.query['sid']}.mp3", 'r:BINARY:BINARY').read
res.body = str
res['content-type'] = 'audio/mpeg'
Can anyone tell me how to get audio streaming to all browsers through a Ruby servlet?
Note: This is not a duplicate. I've been thorough a lot of SO answers, but none work because they are designed for static files, not servlets.

I am using RecordRTC to allow my application user to record their video and upload. This works perfectly fine with Chrome and Mozila Firefox but Safari having trouble playing recorded videos.
I research for the same and found mimeType: 'video/webm\;codecs=vp8' to be used for safari. However this still won't work on Safari browsers. (mac OS x and iOS)
Can someone please help me with this? I have multiple users working on different operating systems and working on different browsers and I want to make sure RecordRTC works for all of them.
I am open to change/ switch to any other alternative if available to implement this feature with cross-browser support of course.
I found Twilio but I am not sure whether Twilio supports standalone recordings or not? I mean I just want single user to go on a page record a video and upload.
Please see below my RecordRTC configuration if it helps:
const options = {
type: 'video',
mimeType: 'video/webm\;codecs=vp8',
bitsPerSecond: 128000,
timeSlice: 1000
};
After user completes the recording, I am converting it to a blob and append it to the formData to save it to the server:
var recordedBlob: Blob = recordRTC.getBlob();
formData.append('files', recordedBlob, this.courseComponent?.courseComponent?.name + '.webm');
This recorded video plays fine in Chrome and Firefox but in Safari it Fails.
Please if you can guide me through this it will be great help to me.
Thanks.
Below are the console log snaps:
1.browser does not support media recorder api
when tried to play the recorded video
says browser does not support media recorder api and try using whammyRecorder
I use the AudioPlayer to stream both mp3 and AAC Shoutcast streams on iOS, and in the main it works just fine. However to get AAC to work with a URL that does not end in .aac I had to hack the AudioStreamerCUR.m Objective-C code. I am not an Objective-C programmer and this was done very much on a trial and error basis. As there are number of url schemes used by Shoutcast and Icecast, my hacks are messy and it would be a lot easier to simply send the content-type along with the url like this:
var player = Titanium.Media.createAudioPlayer({
allowsAirPlay: true,
url: myURL,
contentType: "aac"
})
But I can't work out how to get a new property into the AudioPlayer proxy and then across to the actual AudioStreamerCUR.m - it seems some black magic is required. I wonder if there are any magicians who could point me in the right direction?
Thanks.
This is a property currently not exposed though the Titanium AudioPlayer API.

How can a rtmp stream url be retrieved completely with its playpath and be played with ffplay/avconv from a flash plugin. In embedded flash code below rtmp address exits (rtmp://live.atv.com.tr/atv) , however it does not work with avplay since it needs playpath.

Problem Solved: Using wireshark (network analyzer) is much more effective to retrieve paramaters like rtmp url, playpath...
Edit2: Some urls are also embedded in scripts files rather than directly in flash object, this variables are used in flash object above, later.
I would like to open an audio file from an HTTPS resource.
First, I tried using MediaPlayerLauncher like so:
MediaPlayerLauncher mediaPlayerLauncher = new MediaPlayerLauncher {
Media = filename,
Controls = MediaPlaybackControls.Pause,
Orientation = MediaPlayerOrientation.Portrait,
Location = MediaLocationType.None
};
mediaPlayerLauncher.Show();
filename in this case is a URL beginning with https://.
Using Fiddler to monitor traffic, I have noticed that https:// in filename is getting changed to http://.
Next I tried opening the same URL using WebBrowserTask:
WebBrowserTask webBrowser = new WebBrowserTask {
Uri = filename
};
webBrowser.Show();
Checking Fiddler out again, I noticed that two requests are being sent. First is a request to filename by the browser. This results in the "Tap to open file" message to appear in the browser. Tapping it opens the phone's media player (MediaPlayerLauncher?), which sends another request -- in this case, the https:// changed to http:// again (which is similar result to first attempt).
The server I am getting the file from only supports HTTPS, hence the problems arising when the media player requests the file as HTTP.
Is there anyway to stream a file from an HTTPS resource? Does Windows Phone's media player even support it?
Pointing location on the internet for the MediaLuncher is a bad idea. It will freez UI thread and your app won't be responsive. Try first download the audio as a stream and then play it. Use WebClient to open a stream. HTTPS can be open in WP7, so that shouldn't be a problem.
it's a week that I'm trying to write a program that download correctly from youtube
a video
the problem is this:
I've done via httpwebrequest a simple downloader and all work well.
I've tried download a mp4 video from a local server (uniform server) and all goes well, video is the same, work and is valid mp4.
When I download the same video from youtube something strange happens:
It fill some characters in downloaded file with sequence EF BF BD
for example when encounter character E2 (I've compared the two files one from youtube and the original). Googling around I discover that a server return this kinda sequence when encounterd a invalid char for your encoding, now I'm on wp7 and I can't set
Accept-Charset:
ISO-8859-1,utf-8;q=0.7,*;q=0.7
here's others useful data: I've try with these:
_webRequest.Method = "GET"; //also POST
_webRequest.UserAgent = #"Mozilla/5.0 (Windows; U; Windows NT 6.1; it; rv:1.9.2.16) Gecko/20110319 Firefox/3.6.16";
_webRequest.Accept = #"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
_webRequest.BeginGetResponse(_onDownload, userState);
format url from youtube
Any Idea?
thanks
Can you set the header using the _webRequest.Headers method? See these related questions:
