python wrapper around libmtp to talk the media transfer protocol
python-mtp is a wrapper for libmtp, allowing python applications to communicate with all MTP devices that are supported by libmtp. For supported & tested devices see there. It is implemented using cython.
Simple test scripts can be found in examples/ for all major operations.
Little warning: MTP is a crap and doesn't work well or reliable. Neither this wrapper nor libmtp are to blame.
The wrapper makes use of the with statement and can be used as simple as:
from mtp import MediaTransfer
with MediaTransfer() as mtp:
print('Infos: {}'.format(mtp.get_deviceinfo())
The examples include a simple backup script that copies all files reachable by MTP from the device to the local directory creating a backup directory named after the serialnumber of the device.
- backup: there is a script in the examples/ section that implemtns a
backup of your mtp-capable device
- playlist:
libmtp has a big drawback that is a cache filled at startup. This takes alot of time due to usb initialisation. Depending on the number of files it takes a minute or more. A flag was given to the MediaTransfer-class construtor that allows creating a connection without caching. This renders some functions unusual, others require this mode.
On Andriod devices MTP sometimes doesn't not work if USB-debugging is enabled.
If the screenlock is active MTP is known not to work well on some devices.
Some devices have problems if you wait too long with the connect after plugging in.
A windows phones did a factory reset during MTP reset after connection errors (the reset was issues by libmtp automatically during initialisation).
While libmtp provides errorcodes some functions just return -1 (which is not a listed error). Other functions return a pointer and have no way to determine the cause of the error (they just return NULL).
If you for example upload a file to a location / name that already exists you get no explicit error code but often just a -1.
Setting the debugging level is of some help (LIBMTP_DEBUG=255)
Some files doesn't seem to be "Media" and are not shown via mtp (for me .gpx files did not apear).
