QUESTION

How do you read a Python Traceback error?

Asked 2021-Jun-06 at 10:31

I have run some Python code in Windows 10 and gotten the Traceback error below. Does it mean the string that is supposed to be an int occurs in line 347 of /DeOldify/deoldify/filters.py or line 1943 of /lib/site-packages/PIL/Image.py?

For context, below the traceback error, I've also included the steps that lead to this error (I attempted to colorize a black and white film clip based on the DeOldify Colab https://colab.research.google.com/github/jantic/DeOldify/blob/master/VideoColorizerColab.ipynb but only succeeded at colorizing the first frame as a .jpeg) and the full terminal output.

EDIT: Thanks to @Daweo's response, I discovered the problem was with the arguments I entered into the terminal as indicated by "", line 1. The correct command should have been:
video_path = colorizer.colorize_from_file_name(file_name='my_video.mp4', render_factor=render_factor)
Also, the code for colorizing a photograph is from https://colab.research.google.com/github/jantic/DeOldify/blob/master/ImageColorizerColab.ipynb

This imply something in filters.py is responsbile for such usage of something from Image.py that raised TypeError.

ANSWER

Answered 2021-Apr-16 at 09:13

To combine a video stream with an audio stream, you don't need the concat filter. You can simply just map the streams and copy them.

"ffmpeg.exe" -i "demo.mp4" -i "music.mp4" -map 0:v -map 1:a -c copy "demo_music.mp4"

In your case, the audio is longer than the video so the video will effectively "freeze" after it's finished playing.

How could I debug this considering I don't have access to the problematic machine (a user does)? Could the "not enough frames to estimate rate; consider increasing probesize" message be related to the problem?

Thanks

Edit: I increased probesize and that warning disappeared, but the conversion keeps failing with the same error message "Underestimated required buffer size". I can now reproduce this on one of my Windows machines.

Edit 2: Not a solution but I found out that this problem is gone if using ffmpeg 4.2.3 and was introduced with 4.3

ANSWER

Answered 2021-Apr-10 at 13:16

Since ffmpeg's bug report system does not seem to allow new users (and therefore reports), the only solution I can suggest is avoiding 4.3.x versions and staying in 4.2.3

How to build libobs as dependency of obs-studio-node module?

This module require libobs as dependency. While building this module it download a pre-built version of libobs if none is specified. We can specify out custom libobs as mentioned in README.md

The shell is interpreting the '&' character in your URL ('tvid', 'bossStatus', etc are parameters in the URL), interrupting the ffmpeg command and trying to start a new command. With subprocess you don't have this issue, the command and its arguments are safely separated.

To run it in the shell you need to enclose the URL in double quotes:
