Can't read chinese subtitle in R

[eyedu]

I am using R to perform the function get_caption.

Tried the code on numerous url links but none of it works on videos with chinese subtitle. I am sure that the subtitle is available in all this videos.

Hi @eyedu,

please elaborate on what exactly you are executing and what the output is. This is a python module and there is no get_caption function.

Hi, Thanks for getting back to me.

I was trying to run the package in R for any videos with chinese subtitles and I always get the same error message.

I am sure that the video comes with caption but I just don't know why it didn't work. I try to use python to do the same action but it didn't work as well.

Please see my R code below.

url <- ("https://www.youtube.com/watch?v=4HLSBvlv0Ug&t=85s") caption <- get_caption(url) Error: youtube_transcript_api._errors.NoTranscriptFound: <... omitted ...>omali")

I am still not sure what get_caption does, but seeing that code I would assume that you are using the url as a video id. The video id for https://www.youtube.com/watch?v=4HLSBvlv0Ug&t=85s is 4HLSBvlv0Ug.

Does that solve your problem?

Hi Jonas, thanks for getting back to me, I used python re-run the code and this is what I got.

from youtube_transcript_api import YouTubeTranscriptApi

YouTubeTranscriptApi.get_transcript("4HLSBvlv0Ug")

Hi @eyedu, I think the error message is fairly descriptive here: as you did not specify which language you want, the English transcript is requested, however, there is no English transcript. Just add the language you want: YouTubeTranscriptApi.get_transcript("4HLSBvlv0Ug", languages=['zh-TW'])
