Is this video file (Python)?
I am trying to create a program in Python 2.7 that has the following requirements:
- Lists all video files in Windows.
- Opens each video file using:
os.open(filepath, os.O_RDWR)
- processes the file.
My current algorithm:
- List of all video file extensions. I got them from here
- Scrolling through all files
- If the file has a video extension, then process it
This method has the following disadvantages:
- Some files such as ".dat" or ".am" are used for non-media files.
- Some files with extensions such as .dat are used by other programs (such as antivirus)
What should I do to create a program that meets the requirements above?
Here is my current code:
def is_video_file(filename):
video_file_extensions = (

For now, there is an even easier way to check if a file contains a valid video stream: load the file using the Python MediaInfo wrapper and check for a video stream.
fileInfo = MediaInfo.parse('some/file/name.ext')
for track in fileInfo.tracks:
if track.track_type == "Video":
# success!
I don't know about the effectiveness of this, but it should be at least as fast as doing it with ffmpeg. At least it has a good API and there is a lot of other useful information that you can easily extract from it.

Try using python-magic
which is the best file type detector by reading its contents (usually the first 1024 bytes).
