youtube embed - force subtitles in specific language with default

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

i'm embedding youtube videos with subtitles in specific language (Hebrew, in my case). im using:

hl=He&cc_load_policy=1

to show the hebrew subtitles and that works fine.

However, if there are no subs in my language, i would like to see the English one (if there are any) as a default. is there a way to force that?

You can force the captions and language using cc_load_policy & cc_lang_pref options via

URL:

API:

var ytPlayer = new YT.Player(
    ...
    playerVars: {
        cc_load_policy: 1,
        cc_lang_pref: 'en'
    },
    ....
});
