I have a rev. B Raspberry Pi and want to stream from my Microsoft Lifecam VX-800 to a web server using HLS protocol and avconv/ffmpeg, preferably without using raspivid because it's not working (couldn't figure out why). The stream needs to be fed to jwplayer. I went through a lot of guides but none seem to be fitting my needs. Could you give me detailed instructions on how to do the live streaming or give me links to detailed tutorials that you tried and worked?
Thanks.

I was trying to generate video thumbnail in Laravel using ffmpeg, but the shared hosting (like Godady) doesn't support ffmpeg due to its consuming a lot of resources!
So, is there anyway to do this (like reading the file byte after byte).
Thanks.
If the video can be played back in the browser you could try using the Canvas feature of html5 to playback the video in a canvas and then post a still from that video to your server using javascript... Maybe you could even automate it, or if you only have a few dozen videos do it by hand...

I'm working on a simple musical instrument tuner in Ruby (2.0.0) using GTK. When it comes to audio playback though, I don't know where to start looking for a suitable gem. Any recommendations? My idea was to package audio files of the 12 notes of the chromatic scale, but I can't seem to find audio samples of these.
I should also say that I'd much prefer if it was cross-platform!
Not sure it can help you, but the only one I came across is this one
It's based on libsndfile
You might also wanna checkout this simple audio player using GTK on SouceForge.

Is there an open source Ruby framework that allows working with multimedia (video, sound, etc) similar to Flash, including Display Object hierarchy, that is not targeted for video games?
I'm looking for something between Ruby/Processing with a more object oriented API.
You could take a look at Ruby-Processing that runs on jruby.

I am trying to fiddle with linux audio sub-system. Basically, I am trying to understand how audio input/ouput flows (use of audio encoders etc) when running a linux image on Vbox. Anyone know a good place to start or a good book to refer to.
Your best bet is to follow the Linux Audio User Group. They have a number of resources on their website and their mailing list is also quite active.
This should act as a good starter guide: http://lau.linuxaudio.org/Sound-HOWTO.html
