• Developing a video streaming app [on hold]

  14 avril 2014, par Blue Gene

  I'm developing an app that is peer to peer video streaming, I will use a server to connect the users but the video will be streamed peer to peer.

  My main requirement is that its that fastest to connect users, i.e make the users see each other in less than 5 secs tops, So whats the fastest protocol I can use in order to make such a connection ?

  I'm thinking about what protocols to use, since there are so many of them, What would give the best (fastest) results :

  RTMP,RTMFP,WebRTC ?

  Should I use ffmpeg ? I couldn't understand why it is used for.

  I am thinking about using H264.

  I was using TokBox and QuickBlox, but north are pay-per-users/minutes, And I want to have the users stream one to another, the server will be used only for connecting them.

  Thanks.

• Developing android app in window(O.S) with ffmpeg library

  19 avril 2014, par PKTomar

  I want to develop an application by the help of "ffmpeg" library. My developing environment is Windows(O.S.) based. I done lot of Google but find all the tutorial which are linux(O.S.) based.

  That's why i download "Cygwin". I try to follow all the steps as in linux based tutorial.

  http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/comment-page-3/

  But I stuck on running following command :

  "sudo chomd +x build_android.sh" when entering passphrase it gives error "Command Not Allowed". Actually this command used to check that build_android.sh file is executable or not. That's why I skip this step and run another command "./build_android.sh" which is used to create folder "android" in ffmpeg library. But this command give many errors. I try to remove one by one but after removing one error getting another list of errors.

  After all these step I feel that there is some problem in executing script file in windows base environment.

  Now I need help, any tutorial which is completely based on windows(O.S.) based.

  :Thanks :

• Best practices for developing scalable video transcoding server on Amazon Web Services ?

  6 septembre 2016, par undefined

  What do people think are the most important issues when developing an application that is going to allow users to upload video and images to a server and have them transcoded by FFMPEG and stored in amazon S3 ? I have a couple of options ;

  1) install FFMPEG on the same server that handles file uploads, when a video is uploaded and stored on EC2 instance, call FFMPEG to convert it then when done, write the file to S3 bucket and dispose of the original.

  How scalable is this ? What happens when many users upload at the same time ? How do I manage multiple processes at once ? How do I know when to start another instance and load balance this configuration ?

  2) Have one server for processing uploads (updating database, renaming files etc) and one server for doing transcoding. Again what is the best way to manage multiple processes ? should I be looking at Amazon SQS for this ? Can I tell the transcoding server to get the file from the upload server or should I copy the file to the transcoding server ? Should I just store all files on S3 and SQS can read from there. I am trying to have as little traffic as possible.

  I am running a linux box as the upload server and have FFMPEG running on this.

  Any advice on best practices for setting up such a configuration would be appreciated. Many thanks
