youtube-innertube-kotlin

You can download YouTube videos in Kotlin by directly calling the InnerTube API using ANDROID_VR client headers, which eliminates yt-dlp dependencies. This approach provides access to video metadata and download-ready stream URLs for offline viewing on Android.

Handling playabilityStatus errors involves checking the JSON response from the InnerTube player endpoint and applying retry logic with backoff. This ensures reliable downloads even when YouTube returns temporary access restrictions or rate limits for ANDROID_VR client requests.

Yes, you can mimic the ANDROID_VR client by sending specific headers and a structured JSON body to the InnerTube player endpoint. This native Kotlin approach surfaces download-ready stream URLs without requiring browser automation or external Python scripts.

Implementing resume support and progress tracking requires parsing the streaming data from InnerTube to acquire format URLs, then managing chunked downloads with rate limiting and storage checks. This approach ensures safe, resumable downloads even under flaky network conditions.

InnerTube API requests fail to return formats when the JSON body lacks correct ANDROID_VR client constants or when playabilityStatus indicates an error. Applying proper retry and backoff strategies while validating request headers resolves these streaming data parsing issues.
