sequoia-ptpy's Introduction

Introduction

Pure Python implementation of the PTP standard as specified in ISO15740:2013(E).

This implementation is transport agnostic and can be used along with USB, serial or IP layers to communicate with PTP compliant cameras.

The entire codebase, tools and examples are compatible with both Python 3 and Python 2.

Basic Usage

PTPy accomodates both the low-level developers wishing to test their PTP implementation as well as users of the cameras in the market.

By default, PTPy will automatically detect which extension the camera supports and load it so that the interaction is seamless.

The most basic usage of PTPy with a camera connected is:

from ptpy import PTPy

camera = PTPy()
print(camera.get_device_info())

with camera.session():
    camera.initiate_capture()

Developers might want to disable the extra functionality, or impose an extension to use. E.g. when the PTP Extension ID has not been assigned.

It is possible to get bare PTP functionality with:

from ptpy import PTPy

camera = PTPy(raw=True)
print(camera.get_device_info())

with camera.session():
    # Do basic things here.

A developer might want to test the case where the extension is incorrectly identified. This is possible by imposing an arbitrary extension.

Impose MTP (Microsoft PTP Extension) to any camera:

from ptpy import PTPy
from ptpy.extensions.microsoft import PTPDevice as mtp

camera = PTPy(extension=mtp)
with camera.session():
    # Do bizarre things here.

Sessions are managed automatically with context managers. All sessions under a top session with share the top session.

To inspect the current session and transaction use the corresponding properties:

from ptpy import PTPy

camera = PTPy()
with camera.session():
    camera.get_device_info()

    print('Top level session:')
    print(camera.session_id)
    print('Transaction ID:')
    print(camera.transaction_id)

    with camera.session():

        camera.get_device_info()

        print('Shared session:')
        print(camera.session_id)

        print('Transaction ID increases:')
        print(camera.transaction_id)

with camera.session():
    camera.get_device_info()

    print('First session:')
    print(camera.session_id)

    print('Transaction ID:')
    print(camera.transaction_id)

with camera.session():
    camera.get_device_info()

    print('Second session:')
    print(camera.session_id)

    print('Transaction ID:')
    print(camera.transaction_id)

Transports

USB

A proof-of-concept USB implementation is provided using PyUSB. Though it might not work with all USB controllers in cameras today. In some operating systems, it might be necessary to be root in order to access USB devices directly.

For the USB transport, the _shutdown method is provided to explicitly release the USB interface. At the end of the Python interpreter session this will happen automatically.

IP

A proof-of-concept PTP/IP implementation is provided using sockets. Since there is no device discovery implemented yet, the address must be provided directly.

from ptpy import PTPy
from ptpy.transports.ip import IPTransport

# Default PTP/IP port assumed
c = PTPy(transport=IPTransport, device='197.168.47.1')

# Optionally:
c = PTPy(transport=IPTransport, device=('197.168.47.1', 15740))

Extensions

State of the art

Full support for the Parrot Drone SAS extension is provided. Extensions are meant to provice vendor-specific sets of operations, events and properties.

Partial support for Canon, Microsoft (MTP), and Nikon extensions is provided. Full support is expected eventually.

Canon and Nikon extensions integrate their specific events mechanisms.

Extensions are managed automatically for users or can be imposed by developers.

Framework

A developer can take any of the sample extensions as a model for others.

In general extensions do not need to overwrite any base PTP operations, events or properties. Indeed most extensions will add some extra commands.

Installing

To install issue pip install . or pip install -e . for developer mode. The command python setup.py install should also work.

Development

Requirements

A requirements.txt file is provided for ease of development. For developing tests, an additional tests/requirements.txt is provided.

Under Windows, install libusb or libusb-win32 using zadig.

Tests

Vendors might want to test their devices against the hardware tests. These become immediately accessible when a camera is connected.

To launch tests issue python setup.py test.

A convenience Makefile is provided so the command becomes make test.

All tests are implemented using py.test, which can also be called directly: py.test ./tests

TODO

Implement extension mapped codes from PTP1.1

sequoia-ptpy's Issues

Can't import "Range" from construct 2.8.22 package into usb.py

Issue is described here: https://stackoverflow.com/questions/50605894/python-windows-7-importerror-cannot-import-name-x

where the file "USB transport.py" is the same as usb.py

"polling exception: a bytes-like object is required, not 'str'"

I installed sequoia-ptpy via pip, ran

from ptpy import PTPy
camera = PTPy()

and got

Import Error

Is there any package installation other then pip install . or python setup.py install?
Because i keep having Import Error for package

Examples are too basic

Hello,

I realize that this is more of a "feature request" than an issue: it'd be great if we had some more advanced examples that showed things like

Listing/downloading/deleting contents of storage.
Live view.

Thanks for writing and sharing this library, by the way.

Lambda missing 1 required positional argument: 'lst'

Hello,

(this issue is very similar to #20 but I decided to make a new one because it was quite old.)

I cannot connect to my Nikon d7200 via IP using the library. Here's my code:

from ptpy import PTPy
from ptpy.transports.ip import IPTransport

c = PTPy(transport=IPTransport, device='192.168.1.1')

The ip address is correct, since another (but less sophisticated) library is able to connect with the same address. The error I get is:

Error in usb.py event function

The event function in usb.py has the option to be called with a wait parameter. When set to True the event function should wait for and event to be queued if there's no event in the event queue. Unfortunately the event function does not respond appropriately when the wait parameter is set to True. It just goes it's merry way. Here is the function:

def event(self, wait=False):
        '''Check event.
        If `wait` this function is blocking. Otherwise it may return None.
        '''
        evt = None
        usbdata = None
        if not self.__event_queue.empty():
            usbdata = self.__event_queue.get(block=not wait)
        if usbdata is not None:
            evt = self.__parse_response(usbdata)
        return evt

The line 'usbdata = self.__event_queue.get(block=not wait)' will never execute if the queue is empty so it will never a blocking get. A better approach is this:

    if wait:
        usbdata = self.__event_queue.get(block=True)
    elif not self.__event_queue.empty():
        usbdata = self.__event_queue.get(block=False)

Can not turn Wifi ON

I am trying to turn wifi on sequoia ON and OFF with following code:

#!/usr/bin/env python
import ptpy

camera = ptpy.PTPy()
with camera.session():
    status = camera.set_device_prop_value('WifiStatus', 'ON')
    print(status);

Response is:

Container:
    TransactionID = 1
    SessionID = 1
    ResponseCode = InvalidDevicePropValue
    Parameter = ListContainer:

I suspect problem is in unicode something. If get 'WifiStatus' it returns [u'ON',.......
When I run trigger.py, sequoia takes pictures, so i think my environment is set up correctly.

Update to construct 2.10

Construct 2.8 uses deprecated imports from collections which breaks on python 3.10.
Updating would mostly mean replacing Range and Embed.

How to set-up libUSB on Windows?

I am trying to run the camera control software ptpy 0.3.2
I am using window 10, python38.
I installed the software by pip install ptpy-0.3.2-py3-none-any.whl

In the Windows directory I only have only libusb0.dll in C:\Windows\System32\DriverStore\FileRepository\arduino_gemma.inf_amd64_ccc1c03de7b2c57b\amd64

In the locate_library function in D:\Python38\Lib\site-packages\usb\libloader.py, the find_library is ctypes.util.find_library
It is looking for the following DLLs:
usb-1.0.dll, libusb-1.0.dll, usb.dll, openusb.dll, usb-0.1.dll, libusb0.dll
I have also noticed that none of the above are in the Windows System32 directory. Should the code be modified to look for other DLLs?

How to get live camera stream to process imagery with OpenCV?

I'm trying to do image processing with OpenCV, and I am able to run the trigger example, but I don't want to save the image, I just want to store it in the code as e.g. an OpenCV Mat object for processing. What method do I call to get the stream?

BitField has gone in construct 2.8.x

When I did pip install ptpy it wouldn't import:

This appears to be due to a change in the 2.5-2.8 transition of construct:

Support for IP transport layer

I would like to see support for an IP transport. Some platforms have issues in the USB layer so removing dependency on pyusb would be great.

Any plans to host the project on PyPI?

This project would be a great addition to PyPI, are there any plans to host it there?

Enable ViewFinder on Canon EOS 2000D

I have a CANON EOS 2000D.

I have tried the following implementation in canon.py:

def eos_init_viewfinder(self):
    ptp = Container(
        OperationCode='EOSInitiateViewfinder',
        SessionID=self._session,
        TransactionID=self._transaction,
        Parameter=[]
    )
    return self.mesg(ptp)

This returns a SessionNotOpen ResponseCode.
Can you give an example, how I can activate and deactivate the viewfinder?

I have also tried to get a viewfinder image. I have used the following short script.

camera = PTPy()
with camera.session():
    print('hello')
    result = camera.eos_get_viewfinder_image()
    print('hello')

I set a breakpoint at the first print('hello'). Then I enable the viewfinder at the camera itself. Then I let the program continue.
In the result the Data variable is empty.
Is the implementation missing?

I have also tried to get and set the parameter EVFMode=0xD1B1. I have had no success.
Can you provide more examples on how to set or get CANON specific properties?

Sorry for the noobish questions. I have no experience with CANON PTP.

Thanks for your help.

More examples

Can you provide an example for file transfer please?

Python 3 incompatibility in event polling

I'm new to github and ptpy. Apologies if anything posted here is not in the correct format.

I'm trying to access my Nikon D800 camera using ptpy. I've installed a libusb-win32 driver (for the camera) and am running the example script from here under Python 3.

This is the output from the example script:

ptpy error report.txt

Please note I've added a print(i,device) around line 75 to the example script to see what info I'm getting from my camera.

I emailed Luis Domenzain and he suggested
"This looks like a PTPy bug under Python 3.
Please post an issue to GitHub for follow-up."

So that's what I'm doing :)

Thanks very much for any help you can give me on this one.

Steve C

PS I have tried other driver options from Zadig but I get similar errors in a seemingly infinite loop. This is the only driver option that (finally) exits with a code 0

Driver details:

connection with named camera

Hello

below is a patch that allows to instantiate PTPy() with a string (camera name):
camera = PTPy('NIKON DSC D70')

without breaking the past behavior.

Thank you for this Python PTP implementation!

Release USB

There is no "clean" way to stop the usb connection without a shutdown!
It would be great if we were able to release the usb interface when deleting the PTPy class.
From what i have seen there is no real proper way to release the usb interface.

Session-Handling SessionIDs not following PTP standard?

Hi!
Is there a discussion forum? Do not like to post an issue report each time I have a suggestion.

I have a strange problem with Canon DSLRs and gphoto2 as well as with PTPy. After some shots the device does not react anymore. Gphoto is very complex and not easy to debug. With PTPy I am able to reproduce and debug this behavior and it seems to be dangling sessions.

To reproduce :

with camera.session():

    # The open session and close sessions operations are called
    # in the background as needed.
    print(camera.get_device_info())
    # Allow remote shutter release.
    print( camera.eos_set_remote_mode(1))
    # Actual shutter release
    print( camera.eos_remote_release())
    <Terminate process here: kill -9>

This leads to a dangling session (ID=2). Rerunning the code yields only SessionNotOpen messages and capturing is no longer possible. Manual rebooting of the camera seems the only cure ---
BUT if you insert a second camera.open_session() in front of the capture command you will get a session ID=3 that allows for capturing.
This weird behavior found me to have a closer look at your session code and the PTP Spezifikation.

    def open_session(self):
        self.__session += 1
        self.__transaction = 1
        ptp = Container(
            OperationCode='OpenSession',
            # Only the OpenSession operation is allowed to have a 0
            # SessionID, because no session is open yet.
            SessionID=0,
            TransactionID=0,
            Parameter=[self.__session]
        )
        response = self.mesg(ptp)
        if response.ResponseCode == 'OK':
            self.__session_open = True
        return response

The comment stated that the first call to OpenSession should be performed with a session ID of zero but the Spezification reads the opposite:

PIMA 15740: 2000  
9.2.1 SessionID 
Each session shall have a SessionID that consists of one device-unique 32-bit unsigned 
integer (UINT32).  SessionIDs are assigned by the Initiator as a parameter to the 
OpenSession operation, and must be non-zero.

I suppose that the philosophy behind the PTP SessionIDs is comparable to the one in e.g. IMAP.
Therefore I changed the code a bit

    def open_session(self, session_id = None):
        self.__session += 1
        self.__transaction = 1
        ptp = Container(
            OperationCode='OpenSession',
            # Only the OpenSession operation is allowed to have a 0
            # SessionID, because no session is open yet.
            SessionID= session_id or self.__session,
            TransactionID=0,
            Parameter=[self.__session]
        )
        response = self.mesg(ptp)
        if response.ResponseCode == 'OK':
            self.__session_open = True
        else:
            print('error opening session', response)
        return response

    def close_session(self, session_id = None):
        ptp = Container(
            OperationCode='CloseSession',
            SessionID= session_id or self.__session,
            TransactionID=self.__transaction,
            Parameter=[]
        )
        response = self.mesg(ptp)
        if response.ResponseCode == 'OK':
            self.__session_open = False
        return response

The additional session_id parameter are for testing purpose, only. Utilizing this code the procedure with interrupting the code before close_session is called does no longer stall the camera.
This is for sure a particular finding only true for my system and a canon 6D.

I also suggest to capsulize the sessions in a session class. Without isolating the sessions from each other there is no way to keep track of them. At the moment the sessionIDs are simply incremented. This works as long as the user does only uses really atomistic operations. But if a user needs long running tasks this will lead to problems sooner or later.

Any plans for versioning?

This project would benefit from proper py module versioning and git tags, right now developers have to use whatever is on HEAD or fork and use a branch.

Can we please get better package versioning?

How to send raw commands without writing an extension module?

I found the .send and .recv methods which seem to expect a container like this

 ptp = Container(
            OperationCode='Capture',
            SessionID=self._session,
            TransactionID=self._transaction,
            Parameter=[]
)

How would I use this is the main application to send a simple test command? (as I do not have access to session id / tranasction id)

Sony PTP Extension support

Hi,

when i tried the print_device_info example with my Sony a58 over usb i got the following error:
I don't know if its a bug with your library or pyusb/libusb in combination with my OS (Kubuntu 18.04)

export PYUSB_DEBUG=debug
export PTPY_DEBUG=1
