What is a codec?

- Coder/Decoder. It is part of software or a driver that adds a support for certain video/audio formats.
It means that your OS allows you to play the audio/video file.
(decode to watch, encode to change format into another format).

What I can do if I can't see or hear anything in my videofile?

- Problem is usual that you do not have right codec or you have too many of them.
You should also make sure that all connections are OK (Audio/Video cables).

1. Delete all audio/video codecs (pack and single)
If you want to make it real good:

2. Pick one way to continue.

2.1. K-Lite Codec Pack
(easy to use, but some1 always has problems with codec packs... )

2.2. Codecs that will keep most people happy:
AC3 (new ffdshow have this)
- FFDSHOW is a DirectShow decoding filter for decompressing several video formats, including DivX, XviD, WMV, MPEG-1 and MPEG-2 movies

2.3. If you want to install all codecs, then read next
Video codecs
Audio codecs
AC3 Filter
DivX ;-)
MPEG-1 Layer 3
Ogg Vorbis

3. You will also need player to watch videos
VLC Media Player
Media Player Classic

4. Subtitles would also be nice

5. Can`t see video-file?
Test that what codec you are missing:


Some errors:

I open Media Player Classic and my screen is black?
- If you use GeForce graphic card you might want to update your driver.

I can not see subtitles? (.ogg)
- Are you using player what support subtitles? (Media Player Classic or BSPlayer)
- Have you install DirectVobSub?
- If you use K-Lite, then activate ”enable all streams" in Ogg splitter. Start -> Programs -> K-Lite Codec Pack -> Configuration -> Codec Tweak Tool

I can not see WMV-files?
- Install stuff from Microsoft:
Windows Media Format 9 runtimes
Windows Media Codecs
Windows Media Codecs (for 6.4)

Some .avi files will crash explorer.exe!
- Start -> Run -> write "regedit" and push enter.
Go -> HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
If there is "DivX" -> delete it.
- Then go -> HKEY_CLASSES_ROOT\SystemFileAssociations\.avi\shellex\PropertyHandler\
And delete value (defeault). It will come back, then you can close regedit and restart your computer.

If you do not want to play with regedit you can try this:
- Start -> Run -> write "regsvr32 /u shmedia.dll" and push enter.
To get it back, write "regsvr32 shimgvw.dll".
