Does anyone know how to create an audio player in Brightcove? I've done a lot of research, but I can't seem to find a solution.
Brightcove has instructions on how to do this posted here:

My question is exactly the same as this one, except that... is it possible to achieve the goal with LibVLC? Thanks!
By the way, are there any full-fledged tutorials or books for LibVLC? There are plenty modules mentioned in this page, but without a tutorial it's difficult/impossible for me to understand how they work. So far, the only tutorial I found is https://wiki.videolan.org/LibVLC_Tutorial/ which is very primitive and says nothing about demuxing, decoding, encoding or muxing. Any information or suggestion is highly appreciated!
I'm looking for some general way to get video stream from webcam in Linux and then process and show it in a window. The second part seems simple, but I don't know how to deal with the first one.
Is there some API, lib, docs, etc?.. Where to start?
I've done a little of this before, and you're right, the second part is the easy part. You should take a look at this post for some of the commonly used libraries.
Video capture on Linux?
I would also throw OpenCV on that list, since it helps with both the obtaining and the processing of video streams:
http://sourceforge.net/projects/opencvlibrary/

Good luck!
Are there any good libraries that can help convert an MP3 into an image of its wavelengths (I think that's the proper term). What I'm looking for is a way to generate the wavelengths of MP3s server-side like is done on Souncloud: http://soundcloud.com/smixx/takin-vc-money-money-cash-ipos
What would be the best approach to extact that type of image from an audio file?
This would be the best response from the community:

The correct term is WAVEFORM that's what you see #soundcloud.
From what I've seen, the PHP script is pretty lightweight and awesome!
BTW: I just realized that the stackoverflow question points to the same PHP code #andrewfreiday
EDIT: Just a FYI, I started playing with node.js for a while now and while I was making a simple MP3 player I started using this packaged for the waveform.

I post weekly podcast shows that are about an hour long onto my Wordpress-powered website. Normally I give an overview (a table of contents of sorts) on each episode post. I want to be able to link to a certain time in an audio file using Javascript and/or Flash, so the table of contents is interactive.
e.g., [a href="#time=4200"]Click here to go to minute 42 in the podcast.[/a]
I haven't found any audio players that include this functionality... Does anyone know of a web audio players that features linking to times?
Thanks!
I'm afraid you won't get an answer to this question here. The community on this site could help you to program an audio player doing that, but not point at a player that does it. You should try on another forum, not here.
If your comfortable doing javascript programming, you could use SoundJS.
Hope that helps.
I am trying to make an application for listening to podcasts. Each podcast is an mp3 file, around 50MB in size. After reviewing the Using Audio chapter of the Multimedia Programming Guide, I decided to use AVPlayer, as the other options did not seem appropriate. However, the more I work with AVFoundation, the more complicated it seems and I have a feeling that simply streaming an mp3 file should be easier. Plus on the top of this document, there is a note stating:
Important: This document contains
information that used to be in iOS
Application Programming Guide. The
information in this document has not
been updated specifically for iOS 4.0
Does that mean that I have some other options, or that AVFoundation is maybe an overkill for what I need to do? I would really appreciate it if someone could clear things out a bit and let me know if I'm making something wrong here.
Thanks in advance!
You should explore Cocos Denshion.
http://www.cocos2d-iphone.org/wiki/doku.php/cocosdenshion:cookbook
The audio engine comes with cocos2d, and it is just 5 classes you can include with your project.
It's very simple to use, as you can see from the above link. It's basically just a wrapper for some AVFoundation classes.
The only trick will be to stream your mp3, but it looks like you can simply update the Cocos Denshion CDAudioManager to hand a URL to the AVAudioPlayer, as a start. Whether or not that satisfies your streaming requirement, I don't know.
At the very least, it will give you some AVFoundation code to study.
I just found a pdf with a nice overview of some possible options from this course blog. Together with Julian's suggestion this is all I could find so far.
