• Generate image from a swf file issue

  24 avril 2013, par Rouge

  I am trying to generate first frame of a swf as a thumbnail image so the user can see it before they open the swf file.

  1.Using FFMpeg

  ffmpeg -i movie.swf -f image2 -vcodec png movie%d.png

  using command line with ffmpeg to generate images. the above command will
  give me errors saying

  [swf @ 0x17937a0] Compressed SWF format not supported
  

  2.Using swftools

  Their website provide a tar file to download however, I only have the command line access in the server so I won't be able to install the tools.

  I need to use server side technology because I have hundreds of swf files.

• RTP-Server in Android 4.0 and above

  9 juin 2013, par PowerPC

  Working on Android 4.0+ above.

  I am in process of analyzing ways to live stream my camera video to Window PC using RTP , encoding MPEG-2.

  1. Is there readily available "rtp-server" in android 4.0+ ?

  2. Is following true: : "The Android platform lacks support for
     streaming protocol, which makes it difficult to stream live audio /
     video to Android enabled devices." extracted from website

  3. Currently I analyzed used the ffserver from the ffmpeg
     libraries, but the FPS is < 5. which is far slow. Did any one
     explored other solution which has more FPS ?

  4. Did anybody tried using StageFright for same ? Capturing raw data
     from camera and sending it to stagefright framework for encoding and
     then streaming the same using RTP ??

  Many Thanks.

• Using FFMPEG with Powershell

  22 avril 2021, par Caulen

  I am using Windows Server Edition 2012 and am very new to using Powershell. Basically, I am trying to convert a bunch of video files that are in a directory to .flv. The code I am using is this :

  &#xA;

  $inProcessPath = "E:\Random Videos\In Process\$env:username\"

$oldVideos = Get-ChildItem -Include @("*.mp4", "*.avi", "*.divx", "*.mov", "*.mpg", "*.wmv", "*.mkv") -Path $inProcessPath -Recurse #gets all of the videos

cd "E:\FFMPEG\bin\"

foreach ($oldVideo in $oldVideos) {
    $newVideo = [io.path]::ChangeExtension($oldSong.FullName, '.flv')
    .\ffmpeg.exe -i $oldVideo -y -async 1 -b 2000k -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast $newVideo 
}


  &#xA;

  Whenever I run this I don't get any error messages but ffmpeg doesn't run either. I'm sure I'm overlooking something but have no idea what that could be. I've searched the website and compared code to others and still have no idea.
