I’ve read your old post here http://www.makeuseof.com/tag/force-subtitles-embedded-youtube-video/, but it seems as those there have been some changes since this was posted.
So, I have some videos I want to have on my site in Portuguese. The closed captions (sub titles) on the original site work. But whenever I try plugging in the code, it doesn’t work. Actually, Google vaguely explains this in their support, saying “just add this code:
&cc_lang_pref=fr&cc_load_policy=1” to the video’s embed code.
“cc_lang_pref” sets the language for the captions shown in the video.
“cc_load_policy=1” turns captions on by default.
Well, if you are a novice, you wonder, okay, “So where the heck do I place this code??” I did finally tinker around with it, but it didn’t work.
So, my guess is, that YouTube changed this around.
Here is a sample (the code) of one of the videos:
Thanks! Have a nice day.
