Hey everyone, this is Hacker Public Radio and this is Drupes.
|
||
|
|
And I don't listen to instructions very well and apparently you have to hit the pound key.
|
||
|
|
So I just called in and recorded an episode and did not hit the pound key,
|
||
|
|
so I don't know where that went.
|
||
|
|
You know how I learned this a long time ago that just talking about a technical problem,
|
||
|
|
even if no one's listening or if thousands of people are listening on Hacker Public Radio,
|
||
|
|
really helps you see the problem better, maybe come up with a solution.
|
||
|
|
So if there is a previous recording of me, please delete it and let's listen to this one.
|
||
|
|
So what I'm trying to do is I'm trying to stream sporting events over the internet and it's me recording them with some camcorders
|
||
|
|
and I want to stream it live.
|
||
|
|
And what I have figured out can work is I have a little box that I plug into my Mac that allows me to take RCA in and then I can send it to like you stream.
|
||
|
|
So that's not the technical problem.
|
||
|
|
The technical problem is how to attach the cameras to this thing.
|
||
|
|
And I'm trying to do this on the cheap.
|
||
|
|
So I have a couple of like old Sony camcorders that have an RCA out.
|
||
|
|
And let's say I'm starting with two cameras.
|
||
|
|
I have camera one and a camera two and they're plugged in via RCA cables to a splitter so that I'm allowed to,
|
||
|
|
or I'm able to hook a really crappy old TV up to each one and see what's on camera one and camera two.
|
||
|
|
And then I have a cable go into a video switch like you would hook up your Wii and your DVD player to your television.
|
||
|
|
And I'm pressing the button, camera one, camera two, and there's a moment of hesitation in the stream but then it switches to the camera.
|
||
|
|
And that kind of worked and that's all fine and good.
|
||
|
|
And I haven't really sat down with the solder and iron and tried to figure out all this stuff.
|
||
|
|
But I'm wondering if like all that video switch is doing is making a physical connection probably using maybe like a relay.
|
||
|
|
So I was wondering if I could do that with my Arduino.
|
||
|
|
I think I'm going to try to do that so that I can have a little bitty button and maybe make the switch a lot faster.
|
||
|
|
Between one camera and the next. I'm going to try that.
|
||
|
|
I'm also using the Arduino as a video pass-through to put a score up on the stream so that we can say we're winning whatever.
|
||
|
|
But I'm trying to figure out how to send video wirelessly so I can have one camera maybe like on the press box and one camera somewhere else around the field.
|
||
|
|
So that maybe I could have multiple more more than just two cameras going and I don't know how to properly send wireless video like that.
|
||
|
|
There's wireless internet at the area or at the field but I don't really want to have a bunch of laptops running around communicating.
|
||
|
|
Maybe there's like a wireless way we can send just plug our C-A cables in and then I can have like a battery underneath the tripod the camera's sitting on that's powering in and murder to power these things.
|
||
|
|
I don't know.
|
||
|
|
If anyone has any like knowledge about such things, please tell me it's droops of Gmail or even better the hack and media comment or hack and media.
|
||
|
|
The hack and media comment on the website have a little discussion.
|
||
|
|
And the first time I recorded this episode I hadn't even thought about using the Arduino to switch between the video.
|
||
|
|
Now I'm thinking about it.
|
||
|
|
I think I can just use relays and that wouldn't screw up my signal coming through my RCA cables.
|
||
|
|
I wonder how that would work or if that's a really bad idea and I just never took any electronics classes and I don't know.
|
||
|
|
So if anyone has any thoughts or ideas or examples of how they've done this, that would be super awesome.
|
||
|
|
And if I didn't have to use my Mac and a fancy little box and I could have some sort of old video card that took our C-A-N and used Linux to stream this, that would even be cooler because then I wouldn't have to have my Mac sitting out in the press box or whatever.
|
||
|
|
And you know Linux is awesome too, not just my computer is expensive and I can't afford to replace it.
|
||
|
|
So anyway, hey I ramble a little bit. Did you notice?
|
||
|
|
Anyway, this has been Drupes.
|
||
|
|
See how the community can help me out with this to be awesome.
|
||
|
|
And this has been Hacker Paul the Grady.
|
||
|
|
Gotta hit the pound key.
