• What options are available for speeding up video load times on a webpage when video is hosted on IPFS

  10 août 2022, par Ryan D

  I have a site that pulls videos hosted on IPFS (Interplanetary File System), most of the videos load and play fine but if a user doesn't have a strong internet connection or if a larger video, it constantly buffer's and play's choppy.

  


  Since the video isn't hosted on my server i'm not sure what options I have to help speed the load times up. The original video is uploaded to my site though and I pass it to IPFS to upload directly. I don't currently download it to my server first to speed up the uploading process, or so the user doesn't need to wait for a double upload.

  


  I know youTube has a compression algorithm and does something with chopping up the video into chunks or something but i'm not sure exactly how that works. Im not very experienced with video codec and encoding. Ive heard good things about FFmpeg but not sure if that would help my current situation.

  


  Any ideas or tools I should look into that may help me out would be appreciated. For larger videos I could download to my server first if theres a compression mechanism or something I could apply first to help the overall load times of the site although not ideal for the user uploading.

  


  Im using videoJS for my video player with preload set to auto if that helps at all.

  


  <video width="320" height="240" controls="controls" class="video-js video" poster="{Image URL}">&#xA;    <source src="{IPFS URL}" type="video/mp4">&#xA;</source></video>&#xA;

  


  Options im currently using

  


  Load the video after the DOM has loaded to not slow down page loads

  


  Preload the video

  


  


  


  Although I don't think that does much.

  


  Other than that I don't know what else I can do. Im good with PHP and or Javascript to handle this task if theres something I should look into.

  


  Thanks !

  


• Transcode video using the output format of another video in ffmpeg [closed]

  8 février 2013, par Nick

  I would like to convert videos to the same format as an arbitrary file. This format is not fixed. This "template" file should not be modified.

  Rather than setting the command line options manually each time, is there a way to specify one video as the input, another video as the output format, and then output all that to another file ?

  I don't see anything in the docs about this, but maybe I'm searching using the wrong terms. I'm using OS X, but can use any of the GNU tools as well.

• Tokbox archived video is letterbox (black border around video)

  28 août 2017, par Bijan Markes

  I have archiving setup to save my tokbox publisher streams straight to an AWS S3 Bucket ; But the final saved archive.mp4 is appearing letter-boxed / has black borders around the stream video rather than stretching the video to fit the whole frame. Is there any way to change this ? It is completely on the tokbox end and I also have the fit-mode for the publisher set to "contain" although changing it to cover doesn’t change anything. Thanks.
