I watch movie clips on my PC using one of several media players.

How can I tell which video codec (filter?) is actually being used while I
watch a movie using a particular player?

The exact steps will be different for every type of player, generally you
choose to see the videos properties and you should see information on the
codec. For example in MP (since that is the forum in which you are posting),
you right-click on the name of the video running (assuming the "List Pane"
is showing) and choose Properties or you can use the File, Properties menu

The other option is to find a Codec checking application (like GSpot).

I tried Gspot but I didn't get info on exactly which codec is used.

Let me explain some more. The media players I might use are WMP10, VLC,
Media Player Classic, Gom, Mplayer, Irfanview, etc. Let's say I have a
WMV file. I want to see exactly which decoder file is used by each of
those media players when they play my WMV file.

(I expect some players would use the same decoder as another player.)

You didn't really explain any more, if I go to Properties in WMP, I see
something like:

Audio Codec: Windows Media Audio 9.1, 64 kbps, 44 kHz, stereo 1-pass CBR
Video Codec: Windows Media Video 9

GSpot shows even more info, what else do you want to see?

The codec is determined by the video you are playing, not the player. If a
video file is encoded using WMV3 or avc1, then it needs that codec for
playback, no matter what player you use.

James, I want to know more than which type of codec. I tried to explain
how I want to know which particular file was being used as the codec.

Well no you didn't really explain anything more, you just repeated the
original question.

All you said was "I want to see exactly which decoder file is used by each
of those media players when they play my WMV file."

You are still missing the point, *all* the players used the same codec for a
particular file. If the video is encoded with cinepak, then it needs the
cinepak codec present on the computer to view it, whether you are using WMP
or VLC.

What media player you use has nothing to do with it. The player can't just
decide to use a WMV3 to decode a video that is a 3ivx file.

If with 'file', you mean DirectShow filter, GSpot can show you which
filters will be used to play a video file. Open the file in GSpot and
press the "1" button below MS A/V.

Generally, all players that use DirectShow (the majority) will use the
filters shown by GSpot. However, some DirectShow based players could
override this and use their own filters. For example, WMP will always
use an internal filter for decoding WMV. The internal filters used by
Media Player Classic can be configured in the program's options.

As far as I know, VLC doesn't rely on DirectShow. It has its own code
(libraries) for decoding various formats.

To find the exact file(s) used and its (their) location, use Gspot as
1. load the file and click on 1 under MS A/V, and note the codecs and
2. System menu, click List Codecs and other filters. Find the codec or
filter you are interested in and double click it. A window opens giving the
details of the file.

Incidentally, if you have several codecs that can perform the required task,
you can, by adjusting their respective merits, select which one will be
