Usage

Check if an extension is a video type

from video_extensions import is_video_extension

is_video_extension("mp4")      # True
is_video_extension(".mov")     # True (dot-aware)
is_video_extension("AVI")      # True (case-insensitive)
is_video_extension("txt")      # False

Check if a file path has a video extension

from video_extensions import is_video_path

is_video_path("movie.mp4")                    # True
is_video_path("/path/to/video.MOV")           # True (case-insensitive)
is_video_path("presentation.avi")             # True
is_video_path("document.txt")                 # False
is_video_path(".mov")                         # True (dotfile support)

Access the list of video extensions

from video_extensions import VIDEO_EXTENSIONS, VIDEO_EXTENSIONS_LOWER

# VIDEO_EXTENSIONS is a frozenset of all known video extensions
print(len(VIDEO_EXTENSIONS))  # 36
"mp4" in VIDEO_EXTENSIONS     # True
"txt" in VIDEO_EXTENSIONS     # False

# VIDEO_EXTENSIONS_LOWER contains all extensions in lowercase
# Useful for case-insensitive lookups without calling .lower() repeatedly
"MP4" in VIDEO_EXTENSIONS_LOWER  # True (case-insensitive)

# Iterate over all extensions
for ext in sorted(VIDEO_EXTENSIONS):
    print(ext)
