• DirectShow / x264 / AviSynth and Windows Server 2008 SP2

  15 novembre 2011, par Tim

  I'm having a hard time getting AviSynth to open video files on Windows Server 2008 SP2 (32 bit). I'm aware of the sound card issue, right now I'm using Audio=false. I've tried installing the below, but I always get the error "No combination of filters could be found to render the stream". I'm using DirectShowSource, but I don't have to ... I'm open that can open most formats your average Windows 7 machine can handle.

  I've installed:

  • "Desktop Extensions" - which installed Media Player and codecs
  • haali media splitter and ffdshow
  • Windows Media Services (for streaming, this supposedly had the mpeg codecs, but it doesn't) Windows Essentials Media Codec Pack
  • K-Lite Codec Pack Full VLC
  • QuickTime Tried copying mpeg.dll codecs from 32 bit Windows 7 to Server and regsvr32'ing them, but get error
  • Tried copying *.AX filters from 32 bit Windows 7 to server and regsvr32'ing, but still get AVS error

  AVS Script:

  • video0 = DirectShowSource("video0.avi", fps=30, pixel_type="RGB24", Audio=false)
  • video1 = DirectShowSource("video1.avi", fps=30, pixel_type="RGB24", Audio=false)
  • Dissolve(video0, video1, 30)

  Command Line:

  • x264 test.avs -o test.mp4 --bframes 3 --ref 3 --vbv-maxrate 2500 --vbv-bufsize=25000 --level 40 --threads

  AVS Error:

  • avs [error]: "No combination of filters could be found to render the stream"

  Has anyone gotten this working on Windows Server? If so what filters codecs or other setup do I need?

  Thank you for the time.

• FFmpeg libavfilter watermark ?

  15 novembre 2011, par Çetin

  Since the vhook subsystem has been removed from the latest version of FFMPEG, how can I add a watermark to a video?

  the following software is installed on my server:

  FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1 with libavfilter 0.4.0

  for example: --> but this code does not work.

  exec('ffmpeg -i 01.mpg  -vfilters "movie=0:png:watermark.png [logo]; [in][logo] overlay=10:main_h-overlay_h-10 [out]" -f  flv 03.flv');
  

  Thanks,

• AMV video encoder ?

  15 novembre 2011, par Shimmy

  I'm looking for a converter that can encode input files to amv format output.

  I've found this project, but it looks somewhat outdated and not maintained. Do you know of a solid and reliable amv encoder (any API or tool that can be invoked from .NET), or can you recommend on the one I mentioned?
