• Contributes fix: YouTube video transcrips Import #1091

Background

https://appsembler.atlassian.net/browse/BLACK-2163
By the end of 2021 YouTube Deprecated their Timedtext API. This caused problem for our customers to download automatically the transcripts for their YouTube video for their videos in Open edX. Open edX team is aware of this error https://openedx.atlassian.net/browse/TNL-9460, but there was no movement on solving this issue from open edx end.
We tried to solve this by replacing the API with a new YouTube API, but the new API requires OAuth authentication and only works with videos in the same channel and even with corresponding changes in the codebase the Transcripts didn't work.

Our solution

I developed a new API that responds with SRT version of transcripts for a given YouTube video ID for example https://us-central1-penn-state.cloudfunctions.net/youtube-transcript?video_id=AcZZlbWRyUM You can try this with different videos just replace what comes after video_id= with your YouTube video ID.
After receiving the Transcripts from our API we make a call to transcripts/upload to upload the transcript for a given unit component location, and we store the transcripts. To make it visible in Studio and LMS.
The functionality should work as the following video
