Dear FFmpeg Developers and Maintainers,

I hope this email finds you well.


My name is [Your Name], and I am writing to kindly inquire about a patch I recently submitted as my first contribution to the FFmpeg project. The patch is titled:


"[PATCH] fftools/opt_common: add separator line to show_filters output"


I submitted this patch via email on [Date of Submission], but I have been unable to locate it in the mailing list archives at https://ffmpeg.org/pipermail/ffmpeg-devel/.


As this is my first time contributing to FFmpeg, I am concerned that there might be an issue with my submission method or the patch format. I would be very grateful if you could help me verify:


Whether the patch was received successfully by the mailing list


Whether the patch format meets the project's requirements


If there are any issues with the submission, what I should do to correct them


The patch is attached again to this email for your reference. I have followed the contributing guidelines to the best of my understanding, but I want to make sure everything is correct.


Thank you very much for your time and guidance. I truly appreciate your work on FFmpeg and would be honored to contribute to this project.

Add a separator line to show_filters() function output to maintain
consistent formatting with other show functions like show_codecs,
show_formats_devices, etc. This provides uniform formatting across
all command-line output functions for better readability and
parsing by external tools.
