(in order to make it “easy” for the readers who could be “confused” by correct terms), and the resulting ubiquitous ignorance and lack of knowledge. However, the common practice in digital video is using these two terms interchangeably, which is caused by years of industry obfuscations, greedy proprietarism (pretending that their codec is a format is a common business model for codec vendors and a significant source of their income, as it ties the customers to their products), intentional lying in various magazines, websites etc. It is an MP3 file and it can be decoded with other MP3 decoders, too.

For example, when you encode an MP3 file with the LAME codec, it is not a “LAME file”, “LAME format”, “LAME audio” or just “LAME” – you don't encode “to LAME”. This all means that audio or video does not have to be decoded with the same codec it was encoded with. Avidemux contains its own copy of libavcodec, external FFmpeg is not used) is used for decoding and encoding of many formats. A built-in libavcodec library from FFmpeg (i.e. In particular, as a cross-platform application, it cannot use any DirectShow or VfW decoders or encoders, which are specific to Microsoft Windows.Īvidemux does not use external FFmpeg. Official Avidemux packages for Microsoft Windows include all external encoders (like Xvid) and decoders and other libraries, so there are no dependencies for them. That's why installing any video codec (for example DivX or Xvid) in the hopes of using it for decoding in Avidemux is a wasted effort (however, Avidemux can use Xvid for encoding). The only thing these two programs have in common is that Avidemux includes several filters ported from MPlayer (like denoise3d), plus it uses libavcodec and other libraries (which are used by MPlayer/MEncoder as well as virtually any free software video program).Īvidemux does not use any external video decoders.

It is not a GUI for MEncoder, it is a standalone program which uses its own code for video editing, reading and writing. This is completely false, even though it contains some borrowed code from these projects.Īvidemux is not an MEncoder frontend. Some people believe it uses MEncoder, Transcode, FFmpeg or MJPEG Tools for encoding.

In general, Avidemux does not need external software for reading and writing.
