ValueError: not enough values to unpack

[yagarea]

Hello, I am trying to use this plugin but when I use it I get this error:

Traceback (most recent call last):
File "/home/john/Projects/autotranscoder/./transcoder.py", line 12, in
FFProbe(file)
File "/home/john/.local/lib/python3.9/site-packages/ffprobe/ffprobe.py", line 54, in init
self.streams.append(FFStream(data_lines))
File "/home/john/.local/lib/python3.9/site-packages/ffprobe/ffprobe.py", line 114, in init
self.dict.update({key: value for key, value, *_ in [line.strip().split('=')]})
File "/home/john/.local/lib/python3.9/site-packages/ffprobe/ffprobe.py", line 114, in
self.dict.update({key: value for key, value, *_ in [line.strip().split('=')]})
ValueError: not enough values to unpack (expected at least 2, got 1)

This is my code

#!/usr/bin/env python

from ffprobe import FFProbe
import os

path = "/home/videos/"

for files in os.listdir(path):
    file = os.path.join(path, files)
    if os.path.isfile(file):
        FFProbe(file)
        print(metadata)

I am 100% sure that directory exists and for loop generates valid paths to video files.

How can I fix it ?

I encountered the same issue. The problem is the code assumes all information within the "stream" tag are one liner of the form <KEY>=<VALUE>.

But ffprobe may return multi-line <VALUE>. For example, my ffprobe output is like:

There are sub-fields [SIDE_DATA] and multi-line field like displaymatrix that messes up the parsing logic.

I have addressed this issue by simply ignoring multi-line data in my fork https://github.com/erat-verbum/ffprobe-python

Feel free to use it.

[jboy]

If anyone's looking for a longer-term solution, I've switched to a ffprobe -print_format json command-line that should handle multi-line data without any problems (because it's all JSON, so it doesn't need to be parsed line-by-line), plus a bunch of other bug-fixes, features, and improvements, in a fork:

(Python3 only, sorry.)
