Is always "AVC" = "H.264" ?

[mike23]

When I use well known mediaInfo tool to get the information about the used Codec in a video it shows oftentimes

"AVC"

Does that always mean H.264?

And similarly: If I use H.264 codec for encoding: Does it always show SVC in MediaInfo?

Is label AVC container-dependent (e.g. only in MP4)?

AVC is the MPEG name for the exact same standard as ITU's H.264. (Technically, MPEG-4 Part 10, Advanced Video Coding.) Likewise, HEVC is the MPEG name for ITU's H.265. They've stopped competing with slightly different standards (like H.262/MPEG-2 and H.263/MPEG-4) since AVC; it just makes more sense to have a single standard.

SVC is a special profile of AVC Baseline, so it would only show up as that if that profile was active. Outside of broadcasting, SVC is extremely uncommon.
