Play Apple's .caf audio file on a webserver? I have .caf audio files (Apple's open audio format) stored on my webserver and want to play them from a web browser on any O/S.
I understand, this doesn't seem like the solution you're looking for, but...
Several weeks ago we faced the same problem. We have several clients which are posting audio files to the web site from theirs iPhones, and we need to play audios on the web site.
But we didn't find any suitable flash player with .caf format support.
So we decided to convert .caf to .mp3 on the server through the ffmpeg.exe utility.
Happily, there a lot of flash players with .mp3 support.
Now I have not tried this... but...

Seems to suggest that .CAF and .AIF may work interchangeably (It suggests that to convert to .CAF you convert to .AIF` and then rename the file).
Have you tried renaming it to .AIF and trying to play in a flash/java browser player? Alternatively just send it as a stream to the web-browser and let the client OS work out what to do with it (Like quicktime running inside the browser).
Let me know how it goes.

I keep getting the error: "processing abandoned, this video could not be processed" whenever I try to upload a 107 minute video of an audio recording (just myself rambling thoughts into a microphone the entire time, just a black screen for video). The original audio file is .m4a, and I am trying to convert it into a video file to upload to YouTube. I have tried all the methods that I could find mentioned online, and every time I still get the exact same error. I have tried:
converting from .m4a to .mp4 using VLC and uploading the .mp4
converting from .m4a to .MOV using VLC and uploading the .MOV
converting from .m4a to .mp4 using various online conversion tools and uploading the .mp4
converting from .m4a to .MOV using various online conversion tools and uploading the .MOV
converting from .m4a to .mp3 using various online conversion tools, then converting from .mp3 to both .mp4 and .MOV and uploading the .mp4 and .MOV
verifying my youtube account and enabling the verification feature eligibility settings in the youtube creator studio to allow uploads longer than 15 minutes
re-uploading the same file after the processing failed to try and restart the process
trying different browsers
I also tried exporting the video file again using the default video editor on Windows (the only video editor I have), but I couldn't upload either the audio file (not an option to choose as an import file type) or the video files I created (gave error: "these files have properties that can't be read". I don't know why this error came up either, but maybe it's because the file is corrupted? This wouldn't make sense to me though because I'm able to play it fine (all file types) in the windows default player, VLC, and Audacity. I was able to convert the audio into the video files in VLC too, so I don't know why I can't do the same in the windows default editor.
I realize that similar questions have been asked before on here, but none actually give a solution that works for my problem. Any insight into why I may be having this problem, and how I may be able to solve it, would be very much appreciated.
Youtube doesn't allow audio-only uploads. They expect you to have some sort of video content (which is why you'll see album art on music-only uploads). You'll need some sort of video content. Shotcut is a free video editor that may help you out. Or if you're willing to use the command line ffmpeg can help you out
I want to capture audio in the Chrome web browser using MediaRecorder and send the encoded audio data to the Android app for playback in real-time.
I can't find any audio format that is supported on both sides. I was trying to use opus codec, but Chrome only supports webm container, and Android supports ogg.
What is the proper way of doing this? I don't want to use WebRTC. I could use some data converters/encoders, but all libraries I found are obsolete/abandoned/insecure.
The webm container format is sometimes stored in .mkv files.
Android 5+ eats pretty much any webm the Chromium MediaRecorder class delivers. If you give MediaRecorder a MediaStream that came from getUserMedia(), and ask it for the right MIME type, you'll get Opus boxed inside webm.
const mediaRec = new MediaRecorder(stream, {mimeType: 'audio/webm;codecs=opus'})
If you put that into a file, use name.webm or name.mkv to name it. Android has been able to handle it for a long time now.
The mkvtoolnix program helps you examine these webm files to see what's in them.
If this didn't address your question, please make a comment.
In short, I have to play RTSP on a Google TV device (Sony nsz-gs7). How can I do it?
Things I tried:
Use NDK to compile ffmpeg, then ffmpeg converts rtsp to udp etc. - Fails because NDK is not supported in Google TV (see: https://developers.google.com/tv/faq#ndk). This method uses ffmpeg as library.
Put ffmpeg executable (compiled with NDK) in an application, then call the app from command line. (see: http://gimite.net/en/index.php?Run%20native%20executable%20in%20Android%20App - first method). I can deploy executable and set its permissions, but cannot execute it; i get "not found" error (its path is correct). If only I could run an executable file in Google TV, the problem would be solved, I think.
Tried to display in VideoView, like Google TV VideoView playing YouTube rtsp videos, it didn't work either.
These approaches all work on Android phones, but I couldn't make them work on Google TV.
Any tips for displaying RTSP or running executable files? Or do I have to wait for NDK support?
Update: If there is an application which can play RTSP streams, we can also use it as a temporary fix.
The current version of Google TV is based on FFMpeg internally and is supposed to play RTSP content of course, if you try that example, you'll want to refresh the url for the RTSP content as YouTube doesn't keep them live long. Since RTSP is a transport format, not a codec, you might want to say what your encoding is.
That said, I've never made RTSP work myself - so I'm not speaking from experience, but I do trust my colleague Shawn who wrote the answer to the link above.
One of the features we announced at Google I/O 2012 was the ability to write your own transport stream and codec's in Java. That software is currently on the LG and will be on most of the others in the next few months.
If your need is urgent write me at Google or on Google+.
I have searched for various articles about playing mp3 files in firefox but no luck.
I want something similar to this website for playing my audio files:
http://www.waatea603am.co.nz/podcasts
Can anyone tell me how is the audio files being played in the website. I want to do something similar. I cant figure out how it is being done.
Thanks
Here's the JavaScript that makes the links play sound:
http://www.waatea603am.co.nz/Resources/JavaScript/podcast-audio.js
It's basically using the HTML5 Audio element:
<script type="text/javascript">
var snd = new Audio("file.mp3"); // buffers automatically when created
snd.play();
</script>

This isn't really a "programming" question, as much as a "Firefox configuration" question.
Personally:
I don't really have any preferences of "media player" for Linux
I simply use Windows media player for Windows
Windows Media player comes built in with all recent versions of Windows
Windows media is the default file association for .mp3 on all recent versions of Windows
Consequently, Firefox automatically uses Windows Media player to play .mp3's

PS:
Unfortunately, most commercial Internet radio stations seem to use Flash to broadcast audio streams. Sigh...
I'm looking for an audio player (like jplayer) which can be embedded in a HTML page which will allow MP3's to be played but not downloaded.
The problem: Flash players request the audio file from the server so the URL of the MP3 is present in the HTML source and can be copy/pasted in to the address bar to download the track. This will inherently be the problem with most players.
Possible solution: The player accepts some "encrypted" (non-playable) format which is then decoded inside the player. Anything like this exist?
I am not looking for solutions which sound like:
Obfuscating the URL of the MP3
Preventing downloading of the MP3 from third party sites (eg. forums) using .htaccess
Embedding the mp3 inside a flash movie unless this can be automated, since mp3's are uploaded on a regular basis.
Having a URL which only works for a certain period of time
I don't know if this answers your question, but... Have you tried streaming your audio files via flash? I have never heard of someone being able to download a file which was dynamicly called through actionscript... but maybe i just don't know what i am talking about...
