For a server, you definitely want ffmpeg. I would also strongly recommend compiling it yourself (those are Ubuntu instructions, but should work for Debian as well AFAIK) - the best AAC encoder available for ffmpeg (libfdk_aac) cannot be redistributed alongside x264 (because of the GPL), and the version of ffmpeg in the repositories is probably too old for ...

What you are talking about is upscaling and any current HDTV will do upscaling automatically. Upscaling doesn't work miracles though, it will only make it so that the lower quality signal can be watched on a higher quality display. It just multiplies the pixels so that a 720 by 480 (.9 pixel compressed) signal for example doesn't end up only taking up 1/4 ...

Firewire is better for video, because firewire is a more sophisticated interface. Firewire provides for device to device communication, DMA transfers and other performance features that USB does not. Therefore Firewire does not rely on the host computer's CPU. USB does not provide DMA transfers. All data on the USB bus must be managed by the CPU loading it ...

For the best quality and/or High Definition you want to use the fastest computer input you have that your streaming app will accept. That would normally be Firewire. Most online streaming sites will accept both USB or Firewire. Take a look at http://www.youtube.com/user/TEDxTalks/search?query=tedxsanantonio+2011. These are TEDx Talks we shot using a SONY ...

The cabling is likely your problem. The composite cables you're using (red, yellow, white) will only move analog signal from the set top box to the TV. Likewise with RG59 or RG6 (coaxial). While both varieties of cables there are technically capable of passing digital signals (they don't care... they're just dumb cables), set top boxes typically only ...

Unfortunately there is no perfect or exact answer. Your question topic mentions HD-SDI, which is a digital signal. Those tends to degrade 'cliff-wise', unlike analog signals where degradation is gradual. It will partly depend on the quality of the receiving device -- whether or not, or how well, it can capture the signal as the eye pattern turns to mush. ...

Your comparison of WMV to MP4 is a little bit confusing, because you're comparing apples and oranges. MP4 is a container format, which may contain a variety of audio and video formats. Most commonly, an MP4 file will contain wither an MPEG-4 Part 10 (aka H.264) or MPEG-4 Part 2 video stream, although it can contain MPEG-2 or MPEG-1 video streams. There ...

EasyCap 2.0 DC60+ is what I use, and they work great. Make sure you get the DC60+ version, you don't want the older versions. There are a lot of knock-offs floating around--I'd stick with the official one. There's also a good compilation of capture cards on this thread on the Wirecast Forum.

Wowza Media Server on Amazon EC2 is a really cost-effective way to do it, it's very popular among churches because of its on-demand nature and low cost. You spin up the server when you need it, pay a small hourly charge for it, pay for the bandwidth used, and shut it down.

Blackmagic and Livestream are your friends :) You probably want to get 3 cameras - one for the priest, one for roaming action shots and one for the audience. You'll need a whole bunch of microphones and an audio mixer. But you probably already know all this. Buy a Blackmagic TV Studio and buy a Livestream Broadcaster - plug the TV Studio's HDMI output into ...

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 ...

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 ...

As long as the video isn't copy protected, you will want to use a stream ripper instead of trying to do a screen capture of your monitor. Any number of software products are able to directly transfer a video that is in the Flash streaming video format as long as it isn't copy protected. A quick search for "flash video ripper" and your operating system ...

Depending on how often the videos are watched and how big are they in total? Rolling your own might work. For my video streaming needs, I use a dedicated Windows server in a data center (can be as cheap as $110 a month, including a terabyte of disk space and unmetered 100Mb/sec connectivity) and use the included Windows Media Streaming Services to provide ...

I faced a similar problem with a music video. Multiple scenes trying to keep every thing lined up and some lip scync toward the end. Had a hell of a time trying to get it all to match up with the music- scene changes, action, and lip scync. As the audio was located in scene 1 I did not want to try to cut up the song and try to get it to play correctly over ...

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 ...

if you just want a plain rtmp-stream you might look at nginx-rtmp module which looks quite easier to setup 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 nearly no ...

It varies a little from one server to another, but the basic components are an encoder/streaming client on the local client that takes input from the camera and turns it in to a stream that can be sent to the stream server on the VPS. The job of the stream server (such as Red5) is then to provide a publishing point that relays the stream to viewers. The ...

You may want to reupload the file to Youtube. Convert the audio file (preferably your original, uncompressed file) to video with avconv -loop 1 -i cover.jpg -i original-track.wav -tune stillimage -r 1 -s 1280x720 -c:a flac -shortest -v error out-video.ogv (where cover.jpg is the still image you want to use for the video) or using a media converter like ...

Does youtube store different video files for different bit rate? Yes is the technique called "resampling" ? No Does youtube make live resampling for every user ? No All this things happens live ? No, not on youtube. But Yes on twitch.tv Or it encode and save different video files for different bitrate, so that when a user ...

Solved the problem... Go to: Mac System Preferences > Blackmagic Design Set default video standard as HD 1080i 59.94 CamTwist > Blackmagic HD 1080i 59.94 - 8 Bit I figured out my camera settings using the Blackmagic Media Express app, which did detect the camera. Just take a look in the app's settings to find your camera's connection settings.

I found this rack mount device called DVEO D-Streamer IP/DIG. One of DVEO's press relises announced $4000 price for the device. Inputs: HTTP Live (HLS), UDP, RTP, RTSP, HTTP, RTMP (Open Flash), MMS. Output: SD/HD-SDI.

That is completely up to you, how much is it worth to you, etc. Keeping in mind you have to do zero additional work on it to give it to him, and if he were to put it up on his site without your knowledge you would loose nothing.

There isn't support for taking the closed caption data from SDI and embedding it in the video stream. That's why it doesn't work.

Hangouts On Air will allow you to stream your G+ Hangouts to Youtube. This should allow you to reach as large an audience as you wish.

The Easycap Capture adapter is simply a video capture device with no TV tuner, so you would not be able to receive any TV signal. I would recommend the USB TV tuner. I'm not sure whether you will need an Analog or Digital tuner as this will vary according to where you live (here in the U.S. all stations are now Digital). If you are putting this into a ...

Video transcoding is very confusing and there is loads of different options. If you dont want to use FFMpeg you could try VLC Read more about transcoding with VLC here Otherwise FFMpeg (or some kind of wrapper tool) is your best bet. By omitting the -vb option you let FFMpeg decide bitrate. There is also a few Presets you can use for encoding to specific ...

Lithiumhosting is a great provider of streaming audio over the internet. They are pretty cheap too. I use their webservers and I am very pleased with their service! As to what softwares you should use. It depends on how much money you are willing to put into it. A good way of doing it would be to use an analog mixing board and send the audio into the ...

Check out Wowza - it should do what you want. The basic premise of Wowza is video in, video out. It can take multiple video streams into it's encoding engine, and spit them out in various formats, live. If you've got 4 inputs (let's assume they're cameras with HDMI output), you need a computer with 4x HDMI input cards (or 2x computers with 2x cards, ...

You may want to read the spec for Apple's HTTP Live Streaming and see their recommended settings. While the standard seems to be quite well thought through, its real-world performance on iOS still needs some improvement. Switching qualities and streams (for ads) often results in less than stellar experiences. Encoder support also needs to be more ...
