Overview

When itrating over the frames of a video file using the example in the docs, the following exception is raised: AttributeError: 'av.video.codeccontext.VideoCodecContext' object has no attribute 'close'.

This only happens when plugin=pyav.

result = iio.imiter("path_to_file", plugin="pyav", thread_type="FRAME")

Expected behavior

The iteration the complete successfully.

Actual behavior

An exception is raised: AttributeError: 'av.video.codeccontext.VideoCodecContext' object has no attribute 'close'

Traceback:

Investigation

Read an AVI file using the linked example from the documentation.

Reproduction

Read an AVI file using the linked example from the documentation:

result = iio.imiter("path_to_file", plugin="pyav", thread_type="FRAME")
list(result)

• I am/tried using the binary wheels

Research

I have done the following:

• Checked the PyAV documentation
• Searched on Google
• Searched on Stack Overflow
• Looked through old GitHub issues
