==Apple Lossless Encoding==

Shouldn't [Apple Lossless Encoding] be under lossless, or am I missing something? [[User:Ben Newman|118911889]] 13:56, Jun 24, 2004 (UTC)

==Coder/Decoder==

I added this wording, since it's also commonly used. It came back with 44,000 Google hits [http://www.google.com/search?hl=en&lr=&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=%22coder%2Fdecoder%22&btnG=Search], one of which was a definition in the CNET glossary [http://www.cnet.com/Resources/Info/Glossary/Terms/codec.html]. --[[User:Blackcats|Blackcats]] 15:59, 20 May 2005 (UTC)

:I just looked through the article history and found out that a few months ago it used the coder meaning and then it was replaced with compressor. If anything, I think the coder meaning should actually come first, as it has more than twice as many Google hits [http://www.google.com/search?hl=en&lr=&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=%22Compressor-Decompressor%22&btnG=Search]. It would be nice to find a source for the origin of the term, but just going by the sound of it, "codec" sounds a lot more like "coding" than "compressing." I would think that if the original meaning was compressor/decompressor, then it would be called "comdec" or something like that. --[[User:Blackcats|Blackcats]] 16:20, 20 May 2005 (UTC)

::(en)coder/decoder is simply a more general concept. A codec doesn't necessarily compress data, it just converts data from one representation to another. For example, a YUV codec would convert data from RGB to YUV and/or vice-versa. That has nothing to with compression, it might just be a more appropriate representation respectively one that a software or hardware can handle. --[[User:82.141.48.65|82.141.48.65]] 02:44, 7 Jun 2005 (UTC)

== Misleading Information ==

Line 20:

The 4th is similar as the second.

==Question==

How do you get the audio to work?... for the videos at [http://www.visual-voice.com/BNN/serieslist.asp http://www.visual-voice.com/BNN/serieslist.asp]

^^ agreed --Elin

An error pop up reads... This file may not play correctly because it was compressed by using a codec that is not supported.

== Fake codecs ==

Fake Codecs are something that is currently in route to be added/discussed.

== merge endec into codec ==

I suggest that the "endec" article should be merged with the "codec" article, since the current version of the endec leaves me confused about the distinction (if any) between an "endec" and a "codec".

Even if there is some subtle distinction, perhaps they are similar enough that a single article describing both of them (and also the subtle distinction between them) would be better than 2 separate articles -- similar to the way one article covers both [[Myanmar]] and [[Burma]].

== Malware section importance ==

{{u|98.29.45.120}} has marked {{slink|Codec|Malware}} with {{tl|Importance section}}. [[Fake codec]] redirects to this section and has 3 incoming links from other articles. There is only one reference currently cited here but a quick Google search indicates the topic is likely notable. Maybe this is not the best place for the material but it does not appear to merit deletion. Anyone who advocates deleting it should first try to suggest a new ___location. ~[[User:Kvng|Kvng]] ([[User talk:Kvng|talk]]) 16:22, 9 January 2022 (UTC)

There's no audio for the videos when trying to view them on this [http://www.apple.com/support/imac/g4/ iMac flat panel silvery gooseneck white desklamp shape apple G4 computer] with OS X 10.3.9

== Definition not good enough ==

==Conciseness at the cost of clarity==

The explanation "This function is carried out by a video file format (or container), such as *.mpg, *.avi, *.mov, *.mp4, *.rm, *.ogg or *.tta. Some of these formats are limited to containing streams conforming to a small fixed set of codecs, while others are intended to be more general purpose." has just been replaced by a simple link to container formats. I don't think that was a good idea.

Quote: "A codec is a computer hardware or software component", a statement using references from 2 software companies and a dubious About.com article. It then goes on to talk about audio codecs - which is it, computer or audio component, or both? I recommend that the definition be widened from more comprehensive secondary sources. [[Special:Contributions/14.2.203.227|14.2.203.227]] ([[User talk:14.2.203.227|talk]]) 02:44, 31 March 2025 (UTC)

I don't really understand all this but reducing everything down to the bare minimum makes it far harder for people like me to understand. To understand what a codec is you need to know what a container format is and to understand what a container format is you need to know what a codec is. Trying to use wiki to get my head round this is a bit like reading an account of the battle of Gettysburg which has been split into [[Confederate actions at the Battle of Gettysburg]] and [[Union actions at the Battle of Gettysburg]]. Repeating stuff that appears on another page is not the worst thing in the world.[[User:Dejvid|Dejvid]] 19:46, 28 September 2005 (UTC)

:It is a component that operates on a data stream usually audio or video but could also be telemetry etc. The implementation can be in dedicated hardware or in software or somewhere in between as on an FPGA. ~[[User:Kvng|Kvng]] ([[User talk:Kvng|talk]]) 13:32, 3 April 2025 (UTC)

:IMHO this kind of information should go into [[Audio file format]]. --[[User:Hhielscher|Hhielscher]] 20:15, 28 September 2005 (UTC)
