Please correct me, but I'm looking at the concept of a file container, like .avi or .mkv for example as a more generic use of a file extension. In other words, the .avi extension is not enough information to open the contents of the file since .avi files can differ by codec used to encode the contents of the video.
Here's some more information regarding file container differences, coming from wikipedia:
The differences between various container formats arise from five main issues:
1. Popularity; how widely supported a container is.
2. Overhead. This is the difference in file-size between two files with the same content in a different container.
3. Support for advanced codec functionality. Older formats such as AVI do not support new codec features like B-frames, VBR audio, VFR natively, although the format may be "hacked" to add support, creating compatibility problems.
4. Support for advanced content, such as chapters, subtitles, meta-tags, user-data.
5. Support of streaming media
