• Yesterdays date in "MMdd", and specific output folder selection depending on date

  17 mai 2016, par AudioTroubler

  so im trying to manage CCTV footage,
  and so far i’ve come up with this code in powershell :

  Gets yesterdays date in MMdd (todays version will be 0516), -> selects all files that begin with that -> compresses them using ffmpeg -> moves to another folder -> deletes source fules

  $a = get-date -format "MMdd"
  
  $b = 1
  
  $c = $a - $b
  
  $d = $c.ToString("0000")
  
  $inProcessPath = "sourcepath"
  
  $oldVideos = Get-ChildItem -Include @("$d *") -Path $inProcessPath -Recurse;
  
  
  
  Set-Location -Path 'D:\ffmpeg\bin';
  
  
  
  foreach ($oldVideo in $oldVideos) {
  
      $newVideo = [io.path]::ChangeExtension($oldVideo.FullName, '.avi')
  
  
  
  
  
      $ArgumentList = '-i "{0}" -b 200000 "{1}"' -f $oldVideo, $newVideo;
  
  
  
  
  
      Start-Process -FilePath "D:\ffmpeg\bin\ffmpeg.exe" -ArgumentList $ArgumentList -Wait -NoNewWindow;
  
  }
  
  
  
  Robocopy D:\ffmpeg\bin\ntv D:\newpaths "$d *.avi" /mov
  
  
  
  get-childitem "sourcepath" -include "$d *.mp4" -recurse | foreach ($_) {remove-item $_.fullname}

  But, during the testing stage I realised that my implementation wont work when there is a month switch, since from lets say 0601 it wont produce 0531, but 0600.

  Also I need the converted files to be moved to a directory according to current Months, so if i have folder May,June, etc. And i need files that start with 05 go to May folder, and so on.

  Can someone help my accomplish my task, in code or in advice

  My programming knowledge is not enough to solve this issue.

  The main goal is automation

  For the first part courtesy to @dotnetom
  This worked :

  $d = (get-date).AddDays(-1).ToString("MMdd")

  For the second part i’ve comeup with this

      $a = (get-date).AddDays(-1).ToString("MMMM")
  
  
  
  Robocopy D:\Main\AdWords\ffmpeg\bin\ntv "D:\path\$a" "$d *.avi" /mov

• Java, serve HLS live video streams

  12 février 2016, par momo

  I know the topic is not an easy one, but I am looking for a Java class to send an HLS stream from the server to the client.

  I have files being generated greater and greater :

  out.m3u8
  
  out0.ts
  
  out1.ts
  
  out2.ts
  
  out3.ts
  
  out4.ts
  
  out5.ts
  
  out6.ts

  This is generated using ffmpeg from an original source :

  ffmpeg -i http://sourceurl.com:9981/stream/channel/1232131 out.m3u8

  I can play it using VLC.

  Somehow, I need to stream this live to the clients.

  At this point, I do not really care about different bit rates, i just want live streaming to work, in mobile browsers and on desktop browsers.

  I found this class :

  https://github.com/Red5/red5-hls-plugin/blob/master/plugin/src/main/java/org/red5/stream/http/servlet/PlayList.java

  Which might be doing something like that.

  I have pulled in hls.js into my application in hopes of using it for desktops.

  HLS should however work IOS devices without hls.js right now.

  How should one serve HLS content from the server ? It’s very difficult to find any good and simple example to do that.

  Anyone knows of the steps needed to do that ?

  I’ve looked into Wowza and Red5 just a little bit, but unsure what they can provide for me at this stage and seems to be overly complicated to setup just to serve some files. But please explain to me why that’s not the case.
