Mr.Si

Thank you all!

This place has always been the fountain of all knowledge.

Hi all,

It's been a while since I've posted, but I wonder if anyone could help me?

I'm looking for a sound effects library online ideally, so I can download the stuff in wav or mp3 etc, that is also able to be re-broadcast on YouTube without being flagged for copyright.

I'm specifically looking for thunder and lightning type SFX.

Are there any resources you would recommend?

Many thanks in advance,

Simon

First of all, WOW!

I've been reading this thread with much interest. You're a clever person.

I've only ever used Linux Show Player before as I was running Ubuntu Studio, having not got a mac for QLab etc. I've not heard of MultiPlay before, so I'm massively excited to see this (I use MS Windows too).

I'm definitely going to send a donation and will certainly be using v3 when you release it.

Off to watch the YouTube videos and I'll probably sign up to your forum too.

Thank you very much for all your hardwork into the current version and the previous ones.

We stream on YouTube and the stream is about 5sec behind live.

 

Can you describe a bit more how you've set everything up?

 

I'll try and give you a low-down once I'm back home.

However, I'm going to work on getting an RTMP server set up I think, as it seems to have a good amount of support and being one of the more defacto standards for live streams (from what I've read).

Ok, so I have it working over my lan at home with around 1 - 1.5 second lag so that is pretty usable as far as I am concerned. I am streaming using a custom server via RTMP to my centos 7 server running the SRS software in low latency mode and then pulling that feed onto a second laptop using OBS as a vlc source.

I now need to get that second laptop also setup to stream its video so that laptop 1 can pull its stream, in order to have a 2 way video comms link between venues. I just need to work out if it is possible to get the video stream of venue 1 to show on venue 2’s projector whilst also getting the video stream of venue 2 to show on venue 1’s projector without affecting one another. Does anyone know if that is doable?

For WiFi point to point I will probably get a pair of ubiquiti airmax devices too run in 5GHz in order to have the same lan for both venues.

What would you guys say is a good base specification level for running an OBS system on a dedicated laptop or PC these days?

I like the idea of experimenting with a multiple camera setup, but my existing computers are not really up to the standard of live video processing.

If it helps, I am using a pair of dell latitudes. Both Intel i5 processors (2nd gen) and about 8GB RAM. Both have Samsung SSDs in them. Graphics are nvidia on on one and possibly the 2nd. Currently no capture cards.

...Then just stream over the local network and pick it up with VLC or similar at the other end.

Have worked out the streaming via the net but the lag is awful.

For local streaming, So far, I've tried using the "record" method outputing to a URL but even having opened the port on the firewall, I still cannot get it to display in VLC, so struggling with this element.

Any advice would be welcome here, if it's something you've done before. Alternatively, would I need to set up another machine as an NGINX server?

OpenLP would make it easy, you can configure a "source" on OBS to be a browser window fed from OpenLP which can be keyed over the camera video within OBS. You can set up a custom output on OpenLP to format the song words into an appropriate place, it doesn't have to be the same as the projector output of OpenLP. So then you would just need to capture the camera.

 

You don't really want to be working in composite these days... HDMI capture is readily available and most consumer camcorders output it. Most pro cameras will output SDI.

 

I am not sure about propresenter though.

Thank you. I will try the two open pieces of software together this evening.

My video camera are old school, but I do have an Nikon D7000 DSLR camera that can output in hdmi, so could try that I suppose.

Presumably, for doing 2-way video streaming, I'd need to double-up on the equipment. It could be messy, but doable. Is it possible to use more than 1 capture card per laptop for use with OBS?

 

Would you need more than 1 capture card at each end? OBS will do it but the laptop might choke.

 

We use OBS at our church for streaming with a blackmagic decklink card for capture, it is a very useful bit of software. You don't say what software you are using for words but if it can output to a web browser, OBS can do the overlay for you. It will replace a lot of aspects of a vision mixer, you can play in stills or videos very easily from files.

Yes, that's why I was wondering. But useful to know about OSB doing the overlay. I was just wondering that if I:

- Use cameras on Composite or S-Video into my V4 mixer and then into a relvant capture card with S-video Input

- words laptop sending its video via HDMI (or something else), into a different capture card,

Then both could be sent in to the OBS laptop as different sources, but maybe that's just my analogue brain speaking.

My church uses OpenLP, my parents have gone the ProPresenter route.

It would've been New Wine, and yes some years ago!

 

I do indeed mean Open Broadcaster, it's a great package and will handle holding slides, prerecord playout and other niceties as well as your live camera(s). If you can't get any internet, even 4G, then maybe a good point to point wifi link? Directional access point on a pole to get it clear of passing people/vehicles etc. Then just stream over the local network and pick it up with VLC or similar at the other end.

I shall investigate! I love finding out new things.

I'm sure a WiFi Bridge would be suitable.

To be honest you're probably cheaper webstreaming it, even if the venues have no internet connection a 4G signal is usually plenty for a 720p stream. Hiring a proper wireless video kit (with attendant frequency license) is certainly more expensive than some 4G bandwidth.

 

 

You can do most of this with kit you'll have lying around - laptop with OBS, consumer cameras, USB to composite or HDMI capture card(s), tether to a phone (or router with 3/4G capability). It's all fairly simple and easy actually. If you've got money to spend then the BlackMagic stuff is hard to beat, and their WebPresenter adjusts frame rate to match upload bandwidth so you drop frames rather than drop the whole stream.

Jon,

Thanks for the reply (and long time no see! - that Soul Survivor was a looooong time ago now, or was it New Wine?).

by OBS, do you mean "Open Broadcaster Software": https://obsproject.com/ ? That looks interesting and I'd love to see what that does. In terms of Capture cards, do you have any particular recommendations? I'm on a PC with a dual boot of Windows 7 / Ubuntu Studio Linux and since the software is cross-platform software that should be fine. 4G signal is a little sketchy around our area as it's right at the foot of the south downs. <_<

Hi All,

As a sound guy mainly, I'm unsure of the best way to do this so looking for suggestions as to how it would (or should) be done.

If I wanted to send a video feed (with audio also, with a feed from the mixing console) from one venue to another, wirelessly, what would be the normal / best / typical way to do this?

Audio would either be from a matrix of an analogue or digital console with outputs at line level in either Jack or XLR. Video, well, ideally HDMI as the source, but to be fed with both song lyrics and video feed where a band is. A couple of units I have at my (personal) disposal are an old Edirol V4 mixcer (but that's only S-Video and Composite ) and a Kramer KS41H switch. So 2 very clearly different devices.

This is for an event with 2 churches trying to link up for a conference type event where the Venue 1 is licensed for about 200 less people than Venue 2. I've heard that one of the churches (the one that is less afraid to spend money) says it cannot be done. But I disagree (unless they're meaning with the equipment that THEY have available).

Images would need to be fed to a projector in Venue 1 (locally projected words and a video feed (with audio) from Venue 2). Projected Lyrics and a Video Feed (with audio) would also need to be sent back to Venue 2 from Venue 1. I suppose it's a bit like a teleconference but for an event.

Projected Lyrics would be from a computer.

Video feeds could be from hired professional cameras or even from consumer camcorders with Composite outs that could go into the edirol V4 in at least one venue ( and be scaled up to HDMI?) (I've some VDC Trading composite and S-Video cabling from a long while ago)

There's no WiFi network installed or available.

The buildings have direct line of sight to each other and are probably between 100 - 200m away from each other.

I also appreciate that video is a lot slower than audio, so would need to be delayed accordingly.

I hope that this is enough to go on and I look forward to hearing the options!
