pymediainfo

pymediainfo

pymediainfo is a wrapper for the MediaInfo library. It makes it easy to extract detailed information from multimedia files.

Compatibility

pymediainfo is compatible with the following:

• Platforms: Linux, macOS and Windows.
• Python Versions: Tested with Python 3.9 (the minimum required version) to 3.13, as well as PyPy3.

Installation

Please note that, without the MediaInfo library, pymediainfo cannot parse media files. This severely limits its functionality, allowing it to process only pre-generated XML output from MediaInfo.

Linux distribution Packages

Packages are available for most major Linux distributions. They often depend on the MediaInfo library and are the preferred way to install pymediainfo on Linux, as they allow for independent updates to pymediainfo and the MediaInfo library itself.

PyPI on Linux, macOS and Windows

If pymediainfo is not available for your Linux distribution, or if you're running macOS or Windows, you can install it from PyPI:

python -m pip install pymediainfo

Wheels containing a bundled version of the MediaInfo library are available for:

• Linux x86-64 and ARM64.
• macOS x86-64 and ARM64.
• Windows x86-64 and x86.

If you do not want to use the wheels (for instance if you want to use the system-wide MediaInfo library instead of the bundled one):

python -m pip install pymediainfo --no-binary pymediainfo

Usage

Here are a few examples demonstrating how to use pymediainfo.

Getting information from an image

The MediaInfo class provides a parse() method which takes paths as input and returns MediaInfo objects.

Example snippet

from pymediainfo import MediaInfo

media_info = MediaInfo.parse("/home/user/image.jpg")
# Tracks can be accessed using the 'tracks' attribute or through shorthands
# such as 'image_tracks', 'audio_tracks', 'video_tracks', etc.
general_track = media_info.general_tracks[0]
image_track = media_info.image_tracks[0]
print(
  f"{image_track.format} of {image_track.width}×{image_track.height} pixels"
  f" and {general_track.file_size} bytes."
)

Example output

JPEG of 828×828 pixels and 19098 bytes.

Getting information from a video

In this example, we take advantage of the to_data() method, which returns a dict containing all attributes from a MediaInfo or Track object. This makes it easier to inspect tracks even when their attributes are unknown.

Example snippet

from pprint import pprint
from pymediainfo import MediaInfo

media_info = MediaInfo.parse("my_video_file.mp4")
for track in media_info.tracks:
    if track.track_type == "Video":
        print(f"Bit rate: {track.bit_rate}, Frame rate: {track.frame_rate}, Format: {track.format}")
        print("Duration (raw value):", track.duration)
        print("Duration (other values:")
        pprint(track.other_duration)
    elif track.track_type == "Audio":
        print("Track data:")
        pprint(track.to_data())

Example output

Bit rate: 3117597, Frame rate: 23.976, Format: AVC
Duration (raw value): 958
Duration (other values):
['958 ms',
'958 ms',
'958 ms',
'00:00:00.958',
'00:00:00;23',
'00:00:00.958 (00:00:00;23)']
Track data:
{'bit_rate': 236392,
'bit_rate_mode': 'VBR',
'channel_layout': 'L R',
'channel_positions': 'Front: L R',
'channel_s': 2,
'codec_id': 'mp4a-40-2',
'commercial_name': 'AAC',
'compression_mode': 'Lossy',
…
}

Accessing Track attributes

Since the attributes from a Track are dynamically created during parsing, there isn't a firm definition of what will be available at runtime.

In order to make consuming objects easier, the __getattribute__ method from Track objects has been overridden to return None when a non-existent attribute is accessed, instead of raising AttributeError.

Example snippet

from pymediainfo import MediaInfo

media_info = MediaInfo.parse("my_video_file.mp4")
for track in media_info.tracks:
    if track.bit_rate is None:
        print(f"{track.track_type} tracks do not have a bit rate associated with them")
    else:
        print(f"Track {track.track_id} of type {track.track_type} has a bit rate of {track.bit_rate} b/s")

Example output

General tracks do not have a bit rate associated with them
Track 1 of type Video has a bit rate of 4398075 b/s
Track 2 of type Audio has a bit rate of 131413 b/s
Menu tracks do not have a bit rate associated with them

Parsing pre-generated MediaInfo XML output

pymediainfo relies on MediaInfo's OLDXML output to create MediaInfo objects.

It is possible to create a MediaInfo object from an existing XML string. For instance if someone sent you the output of mediainfo --output=OLDXML, you can call the MediaInfo constructor directly.

Example snippet

from pymediainfo import MediaInfo

raw_xml_string = """<?xml version="1.0" encoding="UTF-8"?>
<Mediainfo version="24.11">
<File>
<track type="General">
<Complete_name>binary_file</Complete_name>
<File_size>1.00 Byte</File_size>
</track>
</File>
</Mediainfo>"""
media_info = MediaInfo(raw_xml_string)
print(f"File name is: {media_info.general_tracks[0].complete_name}")

Example output

File name is: binary_file

Text output (à la mediainfo)

If you want a text report, similar to what mediainfo my_video_file.mp4 outputs, use the output="text" argument with the parse() method. In this case, it will return a string, not a MediaInfo object.

Example snippet

from pymediainfo import MediaInfo

# To mirror a simple call to "mediainfo" without the "--Full" or "-f" option, we
# set "full=False". Leaving it at the default of "full=True" would result in
# more verbose output.
print(MediaInfo.parse("my_video_file.mp4", output="text", full=False))

Example output

General
Complete name                            : my_video_file.mp4
Format                                   : MPEG-4
Format profile                           : Base Media
