Subtitles and MOV are not working anymore

[Atarikid]

With FFmpeg 7.1 up to daily git of 30/12/2024, adding srt subtitles are not working anymore. Works fine with FFmpeg 7.0 and older

Some notes: when removing -tag:s:s:0? tx3g , it does not throw an error but the subtitle cannot be played on several players like QuickTime (macOS).

͏    Works now... Buggy Trac?

Hi,

I noticed that trying to file the issue for the tag query to the Trac project and block it, while checking out the spam monitor. Thanks and sorry.

Some notes: when removing -tag:s:s:0 tx3g, it does not throw an error but the subtitle cannot be played on several players like QuickTime (macOS).

The issue is an issue of ​TagsPlugin, not Trac core.

I think that the plugin just should ignore such an invalid tag query or render an error message like the behavior for query:foo&bar in Trac core.

• Rendering for query:foo&bar: [Error: Query filter requires field and constraints separated by a "="]

Edited: I've filed it an issue of TagsPlugin at ​https://trac-hacks.org/ticket/14378, and I'll fix it.
