Common Wrapper/Interface around various video reading/writing tools to make video reading stable, consistent and super easy around different systems and OS.

Backends

OpenCV (in-development)

# How to Read Video ```python

from vidsz import Reader

# open reader reader = Reader(“static/countdown.mp4”)

# print info: width, height, fps etc. print(reader)

# access specific things print(reader.width, reader.height, reader.fps)

# access number-of-frames/seconds/minutes that have been read print(reader.frame_count, reader.seconds, reader.minutes)

# read frames with while loop while reader.is_open():

# returns ndarry-frame or None if nothing left to read frame = reader.read()

# read frame with for loop for frame in reader:

# use frame however you like pass

# release reader.release()

# or read with a with block with Reader(“static/countdown.mp4”) as reader:

frame = reader.read()

```

# How to Write Video

```python

from vidsz import Reader, Writer

video_fname = “static/countdown.mp4”

# open reader reader = Reader(video_fname)

# start writer with the Reader object # by default it’ll append _out in the name of the output video writer = Writer(reader)

# start writer with your settings; # you can also give any combinations of # following settings with Reader object to # overwrite default settings writer = Writer(“out.mp4”, width=680, height=340, fps=30, ext=”avi”)

# print writer info print(writer)

# write single frame frame = reader.read() writer.write(frame)

# write list of frames # or directly write everything from reader object writer.write_all(reader)

# close off writer.release()

# using “with” block, write “static/countdown_out.mp4” (clone of input) with Reader(video_fname) as reader:

with Writer(reader) as writer:
writer.write_all(reader)
