Update playing videos

[berarma]

Documents changes from godotengine/godot#101958.

• Add information about using -g:v to encode videos with a higher GOP size.
• Add notes and warnings about problems when encoding Theora with FFmpeg.
• Remove note about not being able to seek Theora files.

Please, feel free to correct my writing.

Thanks for writing the documentation along with the PRs!

Here's what I see on a first read. This will be reviewed again when the engine PRs are merged

Thanks for the corrections. I've also reworded some of my changes for the better I hope.

I've filed issues for FFmpeg and added links to them.

Looks good to me.

All Theora FFmpeg issues have been fixed in their master branch. These are the commits:

FFmpeg/FFmpeg@22aa71d
FFmpeg/FFmpeg@84d85e7
FFmpeg/FFmpeg@6e26f57

Thanks to the FFmpeg devs for their quick response.

For now, their daily static builds should be used until these fixes are included in new release.

I'll have to update the documentation, and I'm wondering if I should split this PR in two at the same time, since only one of the two PRs addressed here have been merged.

Yes, can you please split out a PR that only documents the changes from godotengine/godot#101958 (and any other changes that got merged in 4.4, if they exist)? We'd like to get documentation for 4.4 changes merged before 4.4 releases as much as possible.

[berarma]

Done.

I edited the PR description to avoid mentioning godotengine/godot#102360. I'd suggest making a separate PR for the documentation changes for that PR

OK. Forgot to remove it myself.

[berarma]

I've removed the links to the issues in the warning block to avoid more information than strictly necessary.
