FFmpeg time lapse error with globbing/shell issue
π Table of Contents
The issue you're experiencing with ffmpeg time lapse and 'overwrite' error is frustrating and affects users who are trying to create simple videos using FFMPEG. This error can be caused by incorrect globbing or shell syntax, which can lead to unexpected behavior.
We will provide a step-by-step guide on how to troubleshoot this issue and resolve it using the correct FFMPEG syntax.
β οΈ Common Causes
- The primary cause of this error is incorrect globbing. The '*' character in globbing patterns matches any sequence of characters, but it can also lead to unexpected behavior if not used correctly. In this case, the glob pattern 'GOPR*.JPG' may match files that are not exactly named as expected.
- Another possible reason for this error could be issues with the shell syntax or environment variables in the Cygwin setup.
π§ Proven Troubleshooting Steps
Using correct globbing syntax
- Step 1: To fix this issue, you need to use a glob pattern that matches files exactly. You can do this by using the '%' character instead of '*', which matches individual characters. For example: ffmpeg -i GOPR%04d.JPG out.mp4
- Step 2: Alternatively, you can use double quotes around the glob pattern to ensure it is treated as a single argument: ffmpeg -i "GOPR*.JPG" out.mp4
- Step 3: If you are still experiencing issues, try using absolute paths instead of relative paths in your glob pattern.
Using wildcards with specific file extensions
- Step 1: Another solution is to use wildcards with specific file extensions. For example: ffmpeg -i GOPR*.jpg out.mp4
- Step 2: This will match only files with the .jpg extension, and ignore any other files in the directory.
π― Final Words
To resolve this issue, you can try using correct globbing syntax or wildcards with specific file extensions. If you are still experiencing issues, please provide more details about your environment and FFMPEG version for further assistance.
