Numpy Deprecation Warning During Reshape

Expected Behavior

Reading a frame from a video (e.g. via VideoFileClip.get_frame()) should not emit any warnings on a supported, up-to-date numpy version.

Actual Behavior

Every raw-frame decode emits a DeprecationWarning on numpy >= 2.5:

moviepy/video/io/ffmpeg_reader.py:228: DeprecationWarning: Setting the shape on a NumPy array has been deprecated in NumPy 2.5.
As an alternative, you can create a new view using np.reshape (with copy=False if needed).
  result.shape = (h, w, len(s) // (w * h))  # reshape((h, w, len(s)//(w*h)))

The cause is FFMPEG_VideoReader.read_frame() in moviepy/video/io/ffmpeg_reader.py, which assigns directly to ndarray.shape instead of using np.reshape/.reshape():

result.shape = (h, w, len(s) // (w * h))  # reshape((h, w, len(s)//(w*h)))

numpy 2.5 deprecated in-place shape assignment on arrays; a future numpy release is expected to turn this into a hard error. Since this line runs on every frame decode, it's the single most-triggered warning across the whole test suite (it showed up in every test that reads real video frames).

Suggested fix — replace the in-place assignment with a reshape call:

result = result.reshape((h, w, len(s) // (w * h)))

Steps and code to Reproduce the Problem

This is self-contained — it generates its own tiny video, so no external media is needed:

import warnings
warnings.simplefilter("always")

from moviepy import ColorClip, VideoFileClip

clip = ColorClip((64, 64), color=(255, 0, 0), duration=1)
clip.write_videofile("repro.mp4", fps=24, logger=None)

reader_clip = VideoFileClip("repro.mp4")
frame = reader_clip.get_frame(0)  # <-- DeprecationWarning fires here
print("frame shape:", frame.shape)

Output:

C:\...\moviepy\video\io\ffmpeg_reader.py:228: DeprecationWarning: Setting the shape on a NumPy array has been deprecated in NumPy 2.5.
As an alternative, you can create a new view using np.reshape (with copy=False if needed).
  result.shape = (h, w, len(s) // (w * h))  # reshape((h, w, len(s)//(w*h)))
frame shape: (64, 64, 3)

Used medias

None — the reproduction script above generates its own test video via ColorClip.write_videofile().
