• Screenshot of video file in Electron Angular project without ffmpeg

  15 June 2022, by Gary Klasen

  Within my Electron Angular project, I want to preview a video file which is stored locally on Windows / MacOS within a frame, like this:

  


  

  


  On the left side, currently, there is a placeholder image. But i want to have a snapshot out of the video, it is not important at which position of the video this is taken.

  


  Our attempt at the moment is to use fluent-ffmpeg library from npm:

  


  var ffmpeg = require('fluent-ffmpeg');

let command = new ffmpeg({source: "MY_VIDEO_PATH"}).inputOptions('-protocol_whitelist file,http,https,tcp,tls,crypto')

command.takeScreenshots({
    count: 1,
    timemarks: ['5%'],
    filename: "MY_FILENAME"
}, "DESTINATION_FOLDER_PATH_FOR_THUMB");


  


  It takes the screen after 5% of the video would have been played. However, this requires ffmpeg executable to be present, which actually costs more space for the application as we want to use.

  


  So: Can i pick out a screenshot out of a video file without using additional executables like ffmpeg? If there are some suitable npm libaries, this would be also fine, as they are a lot smaller.

  


• MAINTAINERS: Split project server admin list

  MAINTAINERS: Split project server admin list
  This updates the list closer to reality.
  
  Iam not a professional server admin, iam happy to help maintain the box as i have
  
  done in the past. But iam not qualified nor volunteering to fix sudden problems
  
  nor do i do major upgrades (i lack the experience to recover the box remotely if
  
  something goes wrong) and also iam not maintaining backups ATM (our backup system
  
  had a RAID-5 failure, raz is working on setting a new one up)
  Maybe this should be signaled in a different way than spliting the lines but ATM
  
  people ping me if something is wrong and what i do is mainly mail/ping raz
  
  and try to find another root admin so raz is not the only active & professional
  
  admin on the team. It would be more efficient if people contact raz and others
  
  directly instead of depending on my waking up and forwarding a "ffmpeg.org" is down note

• Compile FFmpeg project for ARM in PC Linux 64-bits

  4 April 2017, by Dang_Ho

  I want to compile a simple FFmpeg project for my Arrow Sockit Board with an arm-linux-gnueabihf architecture from my Linux-64bit PC. I don’t want to compile the project in the board directly because of my low CPU and that is not convenient for me.

  I’m using FFmpeg version 2.8.11 and this is my Makefile and my "main.c". I know, my Makefile has something wrong in it. If I command "make", it will compile depending on my PC’s architecture, I can’t use that binary file on my board. So, can someone please tell me how to do it.

  I Cross-Compiled the FFmpeg package and installed into the board. I tested all functions such as ffmpeg, ffplay. All them work. The source code folder is located to /home/hohaidang/ffmpeg-2.8.11
