I want to do live webcast of some ceremonies. I can record .flv files using my webcam and ffmpeg software. Now, if I hire a red5 media server from some hosting company so that visitors can download from that website. Now my problem is how can I upload .flv files LIVE ( when video shooting is still in progress )
Please help how to achieve this
I assume by recording them you mean you are saving them to disk and are not streaming the video? If this is the case you simply need to use an upload form or have ftp / scp access to the hosted server. Pick one of the apps installed and place your flv files in the applications "streams" directory. Once the files are in-place you'll need a way to play them back, which will require a player (plenty of free ones out there like jwplayer). Hopefully this is what you were looking for.

So guys, how do I prevent users from downloading audio files on my web app (running springboot in backend) by accessing the s3 url !
I want to make it impossible to download the audio files in my website ! Any suggestions pls ?
I assume you mean that you want to make it impossible to download the audio files, but still allow streaming them for playback.
You can't.
If it can be played, it can be downloaded. Simple as that.
At best, you can sign your S3 URLs so that they expire after a short period of time. This gives you control over who accesses your audio files, and prevents them from showing up in searches, or linked to from other sites. You can also look into Encrypted Media Extensions, but it's not all that useful for audio since audio is trivially digitally captured on the output.
I am doing a small research project to test DASH streaming on very low bandwidth mobile connections in India.
I have an AWS machine where I can upload video and package it for MPEG-DASH and HLS streaming and create the MPD and m3u8 files.
But I am unable to serve the video.
I have tried with Apache and node.js. I was told that by just placing the folder that contains the mpd nad m3u8 files with the video chunks I should be able to stream the video.
I am not sure what I am doing wrong. Is there any special configuration I need to do to server MPEG-DASH video ? If there a tutorial/blog/github project someone could point me towards, that would be brilliant.
TIA.
Setting up a DASH Media streaming, is fairly involved. You can get all paid services from Bitmovin, Wowza and many others but don't give up yet. There are a lot of open-source stuff out there as well that works. I have been working on DASH for a while now.
Here's my setup,
OS: Ubuntu 16.04
Server: Apache2 (easy to setup): Few edits I had to do: CORS and an alias setting.
Client: Dash.js: Literally just get the dash.js-master branch from github. Don't get stuck with the dash.js-development branch, if you don't wanna end up editing stuff.
Content Generation: ffmpeg and MP4Box
All you have to do for initial setup is make 2 directories in your apache's root directory, (i.e. inside the folder that contains index.html). Your first directory will be the compiled dash.js client and the second will be your content directory.
Point a link on your server to the dash.js reference client, then all you have to do is play your mpd on the client. (Make sure it confirms to the mpd validation norms though)
Now, this might just work only on a computer and not a cell phone, but hey I think you disable all the connections (wireless and wired) on your computer and use one of those wireless dongles provided by Airtel/Reliance/any network provider!
Shall be here to answer more insightful questions, hath need be!
You do not need any server side application. If you are using AWS a simple S3 bucket behind Cloudfront will do the trick nicely, without any EC2 needed at all. Just ensure you have CORS and crossdomain.xml in place.
Stefen Lederer posted a blog about just this set up.
Also, use your browsers developer mode to catch failed requests and console errors which might give pointers as to why it is not working for you.
We have a requirement where we should provide capability to upload files up to 100 GB size. Current flow which we have is to put the file from client location/local system to the application server. Then application server pushes the file to a service account in Google Drive server. I would like to know if there is a way to push the file from local system directly to service account in Google Drive. This would help us to not have to store such big files in application server. Please let me know. Also would like to know if we can actually have Drive installed in our local system to point to a service account. This way these big files can be put into the drive location and it will be synced to server in the background.

The only way I know is for you to upload them. The Upload Files page in the Drive API documentation details this feature. In your case, you'll have to use uploadType=resumable due to the file size you'll upload.

Syncing ala-Dropbox might be a bit tricky, I haven't read anything in the Drive documentation that has this feature. Syncing to desktop is usually just a .glink shortcut that will open up a browser.
I have a server from where a single consumer me download MP4 files. I would like to add the username to the meta-data of the file at the time the user clicks "download". Amazon does something like this for the MP3 files.
Now, a slight variation to this is how would I do the same thing if the files are on Amazon Cloudfront.
Thanks!
You would have to route your request through your web server.
Logged-in user clicks
Web server downloads the MP4 file from S3 to its file system.
Web server uses an MP4 editor to add the correct MP4 metadata to the file.
Web server serves the MP4 file back to the customer as a download.
S3 is dumb file storage, so you can't do any on-the-fly editing or processing. Any such work must occur on a machine with a CPU.
As such, the question you posed could not be accomplished in any meaningful way using CloudFront, since the traffic needs to route back through your server for post-processing anyway.
I'm a C programmer and a total newbie to Flash/video/web world. Don't know where/how to start, and so would greatly appreciate your initial help.
Question
If I need to host flash videos off of my website (instead of embedding YouTube links on my webpages),
AND
If I need to provide player API like YouTube's that can be used, say, for supporting chromeless player versions customizable via this custom API of mine...
THEN
What do I need to do essentially...?
Write a custom Flash video player?
If yes, how? I mean, using which Adobe products / tools / SDKs / language(s)?
Is there anything free/opensource available for doing this? Especially, for Linux platform?
Write a new browser (firefox) plugin for users visiting my site?
Not sure how my custom Flash video player will get to the user visiting my site for the first time?
Any books, resources that cover this problem well?
Does the Flash content need to hosted off of a Windows server only?
Currently lost. Thanks in advance,
/SD
Flash has video playback support built-in, so all you need to do is use the Flash authoring environment or Flex to compile a .SWF file that uses the video API, with some buttons to stop and start the stream, volume, seeking, anything else you want your player to do.
Many people have already done this for you, in a way you can easily use from simple HTML. See eg. OSFLV, Flowplayer, JW...
Write a new browser (firefox) plugin for users visiting my site? Does the Flash content need to hosted off of a Windows server only?
Lord no! Flash video would never have taken off if it was just another custom-server+custom-plugin piece of unpleasantness. Though special streaming servers are possible, for the most part it's just an FLV file sitting on a web server.
(FLV is the video format supported by the Flash video playing functions. There are many, many tools you can use to convert other formats to it; I use Avidemux.)
If you are planning to use a "Progressive Download" approach, then your FLV files can be hosted on a Windows or a Linux box. Be aware that:
it is no as efficient as true
streaming.
you may not use it for live events
nor only for stored video files.
it cannot automatically detect the
end user's connection speed.
it is not possible to jump ahead to
another part while it's downloaded.
the video file will be saved on the
end user's computer.
If you are planning to use a "Streaming" approach then you can either buy and use Adobe's solution (Flash Media Server, available on both Windows and Linux box) or sign up for a hosted solution. On this page you will find recommended providers by Adobe. I personally have been using Influxis's hosting with success for a couple of years already.
You can also write your own streaming server but that would be a lot of hard work. If you are interested in that, I would recommend you have a look a Red5 which is an open source Flash Server written in Java.
