GMC Forum _ Private (Muris) _ You Live Webcam Lessons

Posted by: Milenkovic Ivan Jan 28 2008, 01:58 AM

Hey Muris, I saw you wrote something about webcam live lessons...so can you please write how does that work? DOes it have latency or something.... how do you manage to keep up audio and video synced while playing etc...

Thanks! smile.gif

Good question Ivan! smile.gif

I usually don't have latency issues cause I'm on pretty nice ADSL.
But student must have good connection as well or my alone is useless. wink.gif

Andrew can confirm this:
Couple weeks ago I bought new web cam cause I broke old one blink.gif .
So I wanted to test it,Andrew was online and we started.
We had pretty big latency issue,I was worried a lot!!! ohmy.gif
And tomorrow I figured out why,
on another machine(PC or Mac,not sure) my brother was doing some Rapidshare thing,
both download and upload PLUS I was uploading A LESSON as well laugh.gif

We(crew) have discussed about it and I'm sure
it'll be one of new features to come in the future. smile.gif

Man, GMC just keeps getting better and better! biggrin.gif GMC rules!

Well you know, I think webcam lessons are a fantastic idea! biggrin.gif I really feel like ive wasted alot of money going to my live instructor as I usually end up showing him everything I have learnt here blink.gif It makes far more sense to find a "live" instrcutor via the web as your not restricted by who is is in your local area smile.gif

Getting live webcam lessons will be awesome.. it will be like an enhanced "chat with an instructor" experience smile.gif

Posted by: Muris Jan 29 2008, 06:57 PM

I see Henrik is in the board,let's hear some expert's thoughts!! smile.gif

Well, this is certainly on the "want to do list", but nothing is at all decided. If you want us to move this up on the prioirty list, please post requests for it and we'll look into it more smile.gif

On a personal note, I think it would be waaay cool to do something like this!

Posted by: mattacuk Jan 29 2008, 08:28 PM

Well I for one would much rather spend my money here than through any of the local instructor in my area. smile.gif

It is really just throwing money down the drain sad.gif I put aside $30 a week for live instruction and its not nearly as great as GMC smile.gif

Posted by: Kristofer Dahl Jan 29 2008, 08:30 PM

I agree that this would be way cool! We will have it, no doubt...!

Also it will require a cool and challenging technical solution - with one (or more) streaming servers!

Posted by: mattacuk Jan 29 2008, 08:32 PM

Also the best think is that everyone of our instructors is just awsome - there is no question this would be amaizingly powerful smile.gif

Posted by: Dejan Jan 29 2008, 08:34 PM

It will be great feature indeed smile.gif Looking forward to it biggrin.gif

Did I say GMC rules???

Guess I did. biggrin.gif

Posted by: seagull Jan 29 2008, 08:35 PM

I too like this idea very much. Perhaps something of a virtual tutoring could take place, meaning that both the student and instructor are on webcams and can see each other. That way, Guru Muris for instance can tell if I'm playing those darned 32th triplet legato runs properly. biggrin.gif

But yeah, definitely something I would give an upward thumb!

Posted by: Bondy Jan 29 2008, 08:40 PM

Oh the is gonna be so cool live webcam lessons i better buy a webcam then cool.gif cool.gif cool.gif cool.gif cool.gif

Posted by: botoxfox Jan 29 2008, 09:06 PM

This sounds really cool.

Posted by: Milenkovic Ivan Jan 30 2008, 10:37 PM

Wow this turned out to be a great topic smile.gif

Thanks for the reply Muris and guys, and Muris can you tell us what speed your line is (according to speednet.com) please. I must confess I am very intersted to know how the whole thing works, and to see this great feature one day on the GMC as well.smile.gif

Posted by: Hisham Jan 30 2008, 10:54 PM

this will be a great idea if we start live lessons

Posted by: Batista Jan 30 2008, 10:59 PM

This sound extremely cool and awesome! Can't wait for it biggrin.gif

Posted by: Muris Jan 31 2008, 03:04 AM

Yep,it'll be really awesome when we get this on GMC biggrin.gif

Ivan,my connection is ADSL 2048/256 kbps

Posted by: Stevie·Ray·Vaughn Jan 31 2008, 03:10 AM

So will I need a webcam as well? Or just you? smile.gif

Posted by: Muris Jan 31 2008, 06:55 AM

I gave few classes without even playing a guitar.
So I was only watching a student and giving advices etc,go figure. wink.gif

I think it would be great if we could get a Flash Media Server setup.

We could stream to the server by using a program called Flash Media Encoder. It doesn't require a lot of bandwidth and the program is free to download. The quality you get with it is also pretty amazing.

Go http://www.justin.tv! This site is run off of a Flash Media Server. They also did something quite cool. Instead of relying on a java based chatroom, they implemented a browser-based IRC client. I believe they're hosting their own IRC server as well. This allows for an unlimited number of users and an unlimited number of rooms. Don't know if you guys know what IRC is or not.

Also another thing about the Flash Media Server...it allows more than 1 person to connect to your webcam without stealing all the bandwidth from the person serving up the video.

The downside:
1) It's not free to set this up.
2) streaming video = more bandwidth usage.

I have an idea on how to set this up, however, I've never had a client that has asked for such a detailed web application, so i've never done it.


btw my connection is 8192/512 kbps if you guys need some testing.

Posted by: Muris Jan 31 2008, 06:41 PM

So far I've done it using msn. wink.gif

It's good to know you have some experience in this field Kyle,
might be of great help when GMC starts implementing the feature biggrin.gif

I Think WIll Be A great Idea, I've Fast ADSL and Powerfull Webcam (aka an old videocamera modded, no webcam on the market has the same quality! ohmy.gif )

Sounds nice,may I have your cam then Joe? biggrin.gif

Posted by: Milenkovic Ivan Jan 31 2008, 08:18 PM

Muris, what are your experiences with webcam lessons? Do you have ANY latency at all?

I can send video and audio streams over the net too over the msn, but there is a latency, so no jamming, but I think the lessons could be done, different trip from ordinary video lessons thats for sure..

Posted by: Joe Kataldo Jan 31 2008, 08:39 PM

I spoke with my uncle in L.A. and never had latency issues, sometimes some frames "drop" but only the image...but i think that a dedicated streaming server will solve all the problems!

No muris, you can't!

Posted by: Kyle Logue Jan 31 2008, 09:00 PM

If you used a Flash Media Server then the latency would be determined by how fast the uploaders bandwidth was.

If you have a decent upload speed....4-5 seconds would be the max. If you're on dialup...be prepared for at least a minute.

With a streaming server, latency is cut in half. All downloads of the stream are then handled by the server instead of your computer.

It´s perfect for group lessons on a set topic, in muy case ADSL here let mi Upload at 25kps which is ok with audio bud kinda sucks on video depending the resolution. In my case I can see for example most youtube vids with out any pause for buffering.
If it´s going to happen kinda soon Its a good idea to gather between instructors to jam through webcam, alo I remembered that there was aclient for jamming called ninjajam or something.
