bqapi cannot load pixels as array from video

[anantajit]

Calling image.pixels().asarray() on a BQImage which is a video (4 channel) generates the following error:

Traceback (most recent call last):
  File "main.py", line 11, in <module>
    array = pixels.asarray()
            ^^^^^^^^^^^^^^^^
  File ".../python3.11/site-packages/bqapi/bqclass.py", line 471, in asarray
    return tifffile.imread(io.BytesIO(response.content))
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File ".../python3.11/site-packages/tifffile/tifffile.py", line 424, in imread
    with TiffFile(files, **kwargs_file) as tif:
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File ".../python3.11/site-packages/tifffile/tifffile.py", line 1686, in __init__
    raise ValueError('invalid TIFF file')
ValueError: invalid TIFF file

Package versions:

• Python 3.11
• bqapi-ucsb 1.0.7
• tifffile 0.14.0

Note: I chose this version of tifffile because it matches the version used in bisqueUCSB. Note that the error persists with latest tifffile version 2025.9.30.

To reproduce, run the following:

import bqapi

session = bqapi.BQSession()
session.init(bisque_url="https://bisque2.ece.ucsb.edu")

# uri = "00-sAWcivf6tPqGUk6FsnEX5i" # aerial (works)
uri = "00-FM84WchNQhjwAGaTaNvvBL" # RGB video (does not work)

image = session.load(uri)
pixels = image.pixels()
array = pixels.asarray()

print(array.shape)

The script behaves as intended for the aerial photo commented out above (X, Y, C) but not for the video (X, Y, T, C).
