Only escape backslashes, single quotes, and newlines when writing ffmetadata

[superbonaci]

this documentation is correct:
https://ffmpeg.org/ffmpeg-utils.html#Quoting-and-escaping

this is outdated:
https://ffmpeg.org/ffmpeg-formats.html#metadata

Escaping only backslash \\ is enough but single quotes can be escaped no problem.

[ScrubN]

Did you test this change?

[superbonaci]

yes, you can test with some videos having those letters. These are without the PR, as is working right now:

The missing video is the one with \n in title or description, let me know if you find one

Description is completely broken because the \ns were not escaped.

[ScrubN]

Add a comment somewhere, preferably above the method name, explaining that the documentation is outdated and = ; # do not need to be escaped.

[ScrubN]

Also, have you reported this to the FFmpeg team yet?

[superbonaci]

I've added the 6 videos each one to see is each character is escaped or not. The \n does not mean escape, you have to use \ at the end like you do, like video 2172757417.

The downloaded metadata.txt is:

;FFMETADATA1
title=Questing \\n money runs (2172757417)
artist=gaptyx
date=2024
comment=Originally aired: 2024-06-15 15:04:17Z\
Video id: 2172757417\
Views: 6
[CHAPTER]
TIMEBASE=1/1000
START=0
END=120000
title=Escape from Tarkov

but if you want to put the title in two lines the \n does not mean anything, will be converted to n. Twitch already sends the\u000A you do not have to convert also \n to \u000A, and should look like this:

;FFMETADATA1
title=Questing \\n money runs (2172757417)\
title continues\
last title
artist=gaptyx
date=2024
comment=Originally aired: 2024-06-15 15:04:17Z\
Video id: 2172757417\

[CHAPTER]
TIMEBASE=1/1000
START=0
END=120000
title=Escape from Tarkov

The issue is known: Chaotic escaping rules

[ScrubN]

I did not say n needs to be escaped, \u000A (the LINE_FEED constant) needs to be escaped.

[superbonaci]

Already returned.

Can you add the comment?

[superbonaci]

The missing video is the one with \n in title or description, let me know if you find one

https://www.twitch.tv/videos/2166590043 Description is completely broken because the \ns were not escaped.

yes that's a multi line description, but i meant that the description included the \n literal like this has in the title https://www.twitch.tv/videos/2172757417

[ScrubN]

yes that's a multi line description, but i meant that the description included the \n literal like this has in the title https://www.twitch.tv/videos/2172757417

Yes, that will stay as the literal \n

[superbonaci]

comment done.

Thanks for catching this
