If the the wrapper video server is
not working correctly, we provide some tips to find the
cause and solution to solve the problem on this page. It
is a known problem that the wrapper codes will not
function correctly on some versions of Windows (e.g. NT4)
if the old installation of the wrapper codec
(video-only) is not de-installed correctly before
installing the new wrapper codecs. In this section we
are going to test the installation of the codecs
and use some debug modes to test whether the encoder are
able to read the wrapper AVIfiles or not.
First we are going to check the
installation of the codecs. As the new wrapper server is able to
export both audio and video, two codecs need to be
installed. Use one of the following links below to
verify the installation of the codecs.
After the installation of the codecs is
verified, we are going to set the codec in a debug mode,
that enables you to read the wrapper AVIfiles without a
running server. Before we can begin with the testing you
need to download the pre-created AVI files.
Dowload
the pre-created AVIfiles
Before we
can start the testing, we set the wrapper codec in debug
mode. This can be done be entering the settings menu and
enable the "insert dummy instead"
feature as shown below. In the link above "Check
the adio and video codec" you can find how the
enter the settings menu of the codecs. Please note that
audio and video codec have the same settings menu, so
you only have to enable the "insert dummy
instead" feature in one video server codec.
If the followed the instruction correctly,
the codec is set in debug mode. Before we precede with
the testing we need to unzip the pre-created AVI files.
The following files are present in the zip file:
audio_video.AVI
audio_only.AVI
video_only.AVI
video_only_YUY2.AVI
video_only_YV12.AVI |
WARNING!!
You may only open these files in the
Media player running W9x if the "Do not connect to server"
mode is enabled! |
The audio codec is tested by encoding
the the audio_only.AVI file with TMPGEnc
encoder (can be downloaded for free). If the AVI files
is encoded correctly, you should have an audio_only.mp2
with a length of 10sec. Please play this file in the
media player, and verify if contains sound. While
playing you should hear a variable sine wav. (It can
contain some ticks). If everything is O.K, you can
conclude that the audio wrapper codec is working
correctly.
You can try to encode this file with
your favorite encoder. But please bear in mind that your
encode should support compressed audio in a AVI
file. It is known that LSX v3.5 and Windows
Media Encoder v8 do NOT read compressed audio from
an AVI file. Please set the export mode in the video
server plugin to "RAW audio" for these
encoders.

The next thing we are going to check is
the video wrapper codec. This can de done by encoding
the video_only.AVI in TMPGenc. This file has the RGB32
as video format, which most AVI encoder can encode. If
the encoding of the video_only.AVI is successful you can
conclude that the video wrapper codec is also working
correctly.
If the encoder is able to encoder YUV
(e.g. YUY2, YV12) it is recommend that you export the
video in this format to the encoder. To do this, your
application and encoder need o support this (Adobe
premiere does NOT). As far as I know, only Windows
Media Encoder v8 (YUY2, YV12) and Cinema craft SP
(YUY) encoder are able to encode to encode YUV. You can
check if your encoder is able to encode YUV by encoding
the "video_only_YUY2.AVI" or
"video_only_YV12.AVI" file.
Warning: If your encoder is
able to encode
"video_only_YUY2.AVI" or
"video_only_YV12.AVI" you do not know
for 100% that your encoder is encoding the YUV format as
other installed codecs could convert YUV to RGB for the
encoder.
