Incorrect file naming

[fabian-st]

I'm encountering an issue which results in some files being named incorrectly for no apparent reason
This is especially (but not exclusively) the case when there is a special character (such as .? etc) at the end of the video title.
The media is downloaded successfully but marked as "skipped" (This media may be skipped due to error(s) or not matching a filter condition.)
The NFO/JPG files are named correctly.

Media format: {yyyy_mm_dd}_{title}_{format}_[{key}].{ext}
Sample video: https://www.youtube.com/watch?v=11LHkOv8HBc
Expected filename: 2021-01-13_how-to-build-a-target-frame_720p-avc1-opus-60fps_[11LHkOv8HBc].mkv
Actual filename: 2021-01-13_how-to-build-a-target-frame_720p-avc1-opus-60.0fps_[11LHkOv8HBc].0fps_[11LHkOv8HBc].mkv (.0fps_[11LHkOv8HBc] shouldn't be there)

TubeSync version 0.15.8 with yt-dlp version 2025.07.21 and FFmpeg version N-120361-g829680f96a-20250724.

EDIT: clarified excessive part

This might be related to #1246 but someone needs to trace what exactly is happening.

Important

What format codes are being used for the downloaded files?

What format codes are being used for the downloaded files?

Desired format: 720p (video:AV1, audio:OPUS)
Downloaded codecs: audio:OPUS, video:AVC1
Container: MKV

The following command can be used for renaming as a workaround:

for f in *.mkv; do mv "$f" "$(echo "$f" | sed 's/].0fps_[^]]*]/]/')"; done

Afterwards, no more items are shown as skipped.

The format code numbers are at the bottom of the media item page.
