• What are the video streaming specifics : video coded parameters, web server configuration, video player ?

  8 novembre 2011, par albanx

  With my server I encode videos from any format to mp4 with ffmpeg, for making play them with flowplayer on the web site. The problem is that videos buffering is not working. Video plays once it has been fully buffered (downloaded).

  • Should mp4 videos be encoded in any particular way for having
    streaming work ?
  • Or maybe the IIS7 server need extra configuration ?
  • I am using php for getting video files : getMedia ?file=asd.mp4

  I have IIS7 web server with php. Any suggestions ?

• How to convert fisheye-video into an equirectangular video to use with 360°-video viewers ?

  11 juin 2017, par P. Dee

  Actioncams like GoPro put a wider fov into a standard 1920 x 1080 or higher resolution at the expense of distortion.

  How do I use ffmpeg to convert this fov-encoded format into an equirectangular video to use with 360°-video viewers ?

• Best practice to play segments of larger video files in HTML5 video format

  8 octobre 2015, par zx98

  I have to migrate a legacy project from Windows Media to HTML5 video/audio. The system should provide video/audio content to the web user meeting following criteria :

  1. Playout : Segments (TcIn to TcOut) of large video/audio files should be played "on the fly" to the web user. (Cutting the source material into segments does not work because there is a high overlap rate between segments, so 3-4 times more HDD space and a lot of extra programming would be needed. Markered playout of the large source files is not an option either as there are forbidden parts of the source material which should never be available to the user).
  2. Cutting : In general, users are permitted to make copies of the material. Indeed, by using the dowload function, users can download selected segments. I guess, this is not a problem : a service starts a cutting software (probably ffmpeg) that cuts the video, and the user is notified by email to download the product. (That’s the way I do it now but there might be a more simple option).
  3. Formats : what is the preferred video/audio format that most browsers (Chrome, Firefox, Opera, Android) support ?
  4. Server : If possible, I would keep Windows Server because the database behind is MS SQL Server.

  (Windows Media Server and WMEncoder currently works fine for all the above, however WM is not suppored by browsers any more. That is the reason for reengineering).

  I would appreciate any of your suggestions on how to rebuild this video/audio system. (What software elements to use and how).

  Thank you.

  Dear commenters,
  Thank you for your comments. Please note that the above is one single question, the rest is just a detailed description of the issue/conditions, as recommended by stackoverflow.com. I guess, the answer is also very simple, I try to write it myself :

  1. You should keep the large video/audio files in xxx format because...
  2. You create a playlist file like this example... for each of the the segments.
  3. You install the xxx streaming software component on the web/media server to playout the segments.
  4. You can address and play the segments from the client side web browser like this :...
  5. For asynchronous cutting, yes, I recommend ffmpeg, try these profile settings.

  Just a few parts in bold are missing. Thanks to anyone who can fill them.
