Not saving second time around

[AlbertoMQ]

from vidstab import VidStab, layer_overlay, layer_blend
import cv2
import os

# init vid stabilizer
stabilizer = VidStab()

INPUT_FILE_PATH = ".../image_%06d.jpg"
OUT_FILE_PATH = ".../test1_%06d.jpg"
OUT_FILE_PATH_2 = ".../test2_%06d.jpg"

stabilizer.stabilize(input_path=INPUT_FILE_PATH,
                     output_path=OUT_FILE_PATH,
                     border_type='black',
                     border_size= 'auto')

#I realize I can use apply_transform here, just doing this to highlight issue.
stabilizer.stabilize(input_path=INPUT_FILE_PATH,
                     output_path=OUT_FILE_PATH_2,
                     border_type='black',
                     border_size= 'auto', use_stored_transforms=True)

The second time we run stabilize we get no output. I was trying to apply second transform onto another dataset, but am doing on the same just to check it's not an issue with my data.

Installed using pip, running on Ubuntu 18

Notes on issue

The video writer isn't being reset if the same instance is used multiple times. This should be reset either on entering / exiting stabilize process.

Contained reproducible example:

The resulting output videos are 'stable_1.avi' & 'stable_3.avi' (no output for 'stable_2.avi')

import tempfile
from vidstab import VidStab
import vidstab.download_videos as dl

TMP_DIR = tempfile.TemporaryDirectory()
VID_PATH = f'{TMP_DIR.name}/test_video.mp4'

dl.download_ostrich_video(VID_PATH)

stabilizer = VidStab()
stabilizer.stabilize(VID_PATH, 'stable_1.avi')
stabilizer.stabilize(VID_PATH, 'stable_2.avi')

# Reset writer
stabilizer.writer = None
stabilizer.stabilize(VID_PATH, 'stable_3.avi')
