The minimum software is hardware. You want specialized hardware for doing top quality live streaming encoding reliably. You could use something like the Black Magic ATEM television studio which includes 4 inputs and real time stream encoding capability to produce the conference really well or could use a cheaper stream encoder device that simply produces a ...

No, the display port on your macbook pro is output only. You may be able to use your camcorder as a webcam if it is capable of streaming video over USB or Firewire, though.

I'm pretty sure you can use vlc to both stream and restream it. I use vlc to stream all my tv channels to all my devices(rtsp, mp4, html5). Search for vlc media player streaming like https://www.videolan.org/doc/streaming-howto/en/ch04.html

The obligatory ffmpeg answer (not a very good one, other answers still needed): You could feed your video through ffmpeg -vf drawtext=textfile=onscreen.txt:reload=1 With whatever other drawtext options you need to put your text where you want it, with the font you want. reload=1 makes it check the text file for changes every frame, but doesn't give you a ...

This would be possible using OBS's BrowserSource. First, find the embed code for the stream (in YouTube you can click "Share" and then "Embed"). Find the src="" and copy the URL that's inside the quotes. In OBS, create a new Browser. Paste the previously copied URL into the URL field, and set the Width and Height to your canvas size (or your preferred size)....

For amateur events, SDI may be overkill compared to using simple Component. The key for long runs is to separate the various components so that they don't degrade. There is a similar question here about long distance runs. As for HDMI to SDI, there should be no quality loss compared to HDMI as both are digital formats supporting full uncompressed HD ...

If you just want a plain RTMP stream, you might look at the nginx-rtmp module which looks quite easier to set up than crtmpserver. Just a general suggestion: H.264 compression is a bit CPU-intensive, so if your server is more powerful than your notebook and the server to notebook-connection is good, it might be an idea to stream just "plain frames" with ...

https://net7mma.codeplex.com has a server and client implementation which is compatible with VLC and was created for exactly the scenario you cite. From the website: This project's goal is to allow developers to deliver media to clients freely in less then 10 lines of code utilizing standards complaint protocol implementations. It also aims to provide a ...

That or the UpDownCross converter should meet your needs as long as the frame rates are the same. I'd personally stick with BlackMagic's hardware as you already have their ATEM and they make some of the most cost-effective hardware around. They aren't the top quality brand for sure, but you won't beat the value for the price pretty much anywhere else. If ...

Can't help with freeware, but i can shed some light on the professional side of things. At urgent.fm we use Zenon because most commercial stations in Belgium use it, and our station is one of the starting places for people interested into getting into radio work professionally in our region. That way someone who was trained at our station feels right at ...

Not sure about Windows, but for Ubuntu, you could always check out Rivendell. http://www.rivendellaudio.org/

You should check your recorded video with MediaInfo. Regarding your problem, it shows, if the durations of the video and the audio is the same or not, if the interleave of the audio (the starting offset) is set correctly in which sampling rate your audio was recorded. Then, I would import your video file into Audacity (which imports only the audio, of ...

When I first started doing this, I always thought it was better to give them "clean" audio as well. I've since figured out that they want to hear themselves. Also they want to hear each other, so really you do not want a separate feed for them. Depending on what you are broadcasting, you may not even need the sound from the event. The only issue you're ...

I would suggest you research a bit further and then refine your question. To me it seems that there is a bit of confusion in terms of the software components needed for creating a livestream. First you need to have a software component that acquires a live video from some device. This video needs to be encoded. Once it is encoded it can be streamed by a ...

There are two key ways to deal with the inevitable latency of live video from the other side of the world: Ignore the video, at least for talent or guest queuing purposes. The person is fed mix-minus audio through their IFB. Since it is just audio, and historically was sent over a POTS telephone line, it can have virtually unnoticeable latency to the viewer....

The "JVC GY-HM200SPU 4KCAM Compact Handheld Streaming Camcorder" claims... "When equipped with an optional Wi-Fi or 4G LTE high-speed broadband modem, the camcorder can deliver a live video stream directly to USTREAM and YouTube, while simultaneously recording HD video internally to SDHC/SDXC memory cards. " I believe there are other camcorders in the JVC ...

Keep FLV but trim using demuxer seek and duration. ffmpeg -ss 00:00:03.000 -t 00:00:01.000 -i output.flv -c copy output2.mp4 Also, skip -ss if it's 0 i.e. stream start.

I use Streaming Video Provider - they give me the platform to broadcast live and a live chat integrated to it, while streaming, so that I can chat with my viewers while lecturing. I highly recommend their service: http://www.streamingvideoprovider.com/video-cdn-live-streaming-cdn.html

You may want to look into Camtwiststudio for the mac. I work with Desert Bus for Hope doing a weeklong stream as well and we use it for just the sort of thing you're talking about. Camtwist has built-in plugins for both Twitter and RSS, and can leverage quartz composer to make more complicated overlays. It outputs a video feed for other Mac OS X ...

You need your own stream server. The problem with services like YouTube and Twitch.TV is that your stream has to go through a lot of processing and content distribution on their end before it goes out to viewers. That processing takes time and results in lag. You can send the exact same stream to your own stream server and have it directly related with ...

The more I thought about my requirements the more I was convinced that I needed a wifi enabled "security" camera setup than an action cam setup. I'm giving dropcam a try. It seems to satisfy all my requirements. Broadcast without any additional equipment Schedule recording times remotely from anywhere Broadcast is automatically recorded in the cloud for 7 ...

It depends on the level of protection you want, but no, there isn't really a good way to do it with Wordpress. You can paywall a portion of your Wordpress site, but a live stream isn't going to go over HTTP, it is going to run over an RTMP stream or something similar. Paywalling your Wordpress site will make people pay to find out the name of the RTMP ...

There are quality settings for both the audio and video recording. Have you checked out the video capture settings? Maybe some adjustment here would get the audio and video back in sync. The picture is from this Dell support site. May be some more useful info there. Also, just in general (sorry if it's obvious) are you sure your drivers for the webcam ...

A Raspberry Pi might be what you are looking for. It is a credit card sized Arm based computer running Raspbian (a Debian variant), and at $25 it may even be cheaper than buying several adapters. You could simply attach a web cam to the Pi and attach the monitor or TV via HDMI or Component out. To get to VGA you will need a converter which you can get for ...

It looks like it isn't particularly trivial, however crtmpserver have a tutorial on their wiki here. It looks like you have to configure a lua file and then doing a new cmake of the server. (So very much non-trivial.) As an alternative, there are other servers that may do this for you more easily such as Red5 and also Adobe has a free offering mentioned ...

There are two options, neither of which is particular expensive. You can either use a component cable with a distribution amplifier or if you prefer a digital signal, there are wireless HDMI transmitters that will also work well. A distribution amplifier and a repeater are essentially the same thing, just slightly different purposes. A distribution ...

The only thing I can find about it is to set the Output OnScreen Displays to Off in the settings. If that isn't doing it, then I'm not sure that it is possible.

That appears to be analog signal degradation resulting in a loss of frame syncronization. You may need to add a video amplifier on the end near the camera to boost the signal enough to get it to your computer or possibly use a device that can convert it to digital and stream it over a network connection directly.

What you are referring to is called hot linking, and while it may or may not technically be a violation of their copyright or terms of use (check their website for details) it is still generally considered a poor practice since you are effectively utilizing their bandwidth without mentioning that it is their bandwidth. Your best bet is to contact the ...

The quick answer that worked for me: do NOT save your captured video to a drive on the computer, save it to an external drive that runs at 7200 RPM (many are 5400). This problem was driving me crazy. I checked so many blogs, FAQs and help lines, but nothing worked. Finally a salesman at B&H Photo in NYC pointed me in the right direction (this is ...
