Codec Guide

How can i use (add, install) additional codec like MJPG file codec?
Thanks in advance.

Download whatever codec you need and install it. I can't give a better answer because your question is too generic. Please reformulate the question and be more specific about what you want to do and also why.

I sure understand in generic what to do for using any soft but in particular case how can I use Media Player Classic for playing MJPG files?

ffdshow should be able to decode MJPG video.

If you have trouble playing a specific please, then please upload a sample, then I can find a playback solution for you.

To clsid: Thanks a lot.

to clsid: There is a codec in ffdshow which CAN play mjpg file: it's libavcodec. But I don't know how to actualise this posibility.
Thanks in advance.

ffdshow video decoder configuration -> Codecs -> set MJPEG to libavcodec

to clsid: I did it but Media Player Classic doesnt know file extention .mjpg. How to be with that issue?

Im so sorry never did that

I occasionally forget it too. It is an annoying flaw of the forum software.

Your file is a raw MJPEG video stream. ffdshow can only decode MJPEG video when it is located inside a container format, such as an AVI file. Most players will not be able to play this file.

But I found an alternative solution for you. You can play the file with VLC player.

Thank you, my fiend, but I know about that and use it already. It's not enough for me because the image quality is bad and I know tools to enhance it. But first of all for these tools usage I need to convert files to well-known format. That's the problem I bothering you with . So possibly I need something specialized in this particular case. Would you please help me ?

VLC has a (hidden) convert function.

Menu -> Media -> Convert/Save

I advise to increase the default bitrate to minimize quality loss during conversion.
