Black-screen-on-play bug: rustypipe's default player() uses YT's Web
client, which serves stream URLs that are session/UA-locked. ExoPlayer
fetching with a different UA gets a silent 403 from googlevideo and
renders a black surface.
Fix: pin stream_info() to player_from_clients(id, [Tv, Ios]) — the
TVHTML5 + iOS Innertube clients serve direct-play URLs that work in
any HTTP player. Same trick NewPipe uses. No Apple/iOS code involved
— it's just the API client identifier rustypipe sends to YT.
Also added a Player.Listener in PlayerScreen that Toasts any
PlaybackException (codeName + message) so future stream failures don't
look like silent black screens. Logs to logcat 'StrawPlayer' too.
channel_info(url) UniFFI suspend fn. ChannelViewModel +
SubscriptionFeedViewModel both swap. NewPipeExtractor (Java) is OUT —
zero org.schabi.newpipe classes in the APK now.
Cleanup:
- NewPipeDownloader.kt deleted (was the OkHttp adapter)
- Thumbnails.kt deleted (rustypipe returns full URLs)
- NewPipe.init() dropped from StrawApp.onCreate
- libs.newpipe.extractor removed from build.gradle.kts
- STRAW_USER_AGENT + strawHttpClient() now live in net/Http.kt
- RydClient + SponsorBlockClient + PlayerScreen + PlaybackService all
read from net/Http.kt instead of the extractor package
rustypipe API quirks beat:
- channel_videos(id) is the right method (channel() doesn't exist)
- ChannelInfo struct = basic metadata; Channel<T> wrapper carries
name/avatar/banner + .content is the paginator of videos
- description is String (not Option), subscriber_count is Option<u64>
End state: strawApp Kotlin is ~UI + thin glue to strawcore. The Rust
core handles search / streamInfo / channel / channel_videos via UniFFI
suspend fns. Tokio + reqwest + rustls + rquickjs all packed in
libstrawcore.so (~6MB per ABI). APK 40MB total.
stream_info(url) UniFFI suspend fn replaces NewPipeExtractor's
StreamInfo.getInfo() for both VideoDetailViewModel and PlayerViewModel.
One Rust round-trip drives the detail screen render AND the player's
resolve(). The VideoDetailUiState.info field cached on detail load is
reused by the Download dialog so we don't refetch.
Deferred to U-3.5:
- like_count (rustypipe's player() doesn't surface engagement data;
a separate query is needed)
- related (player() doesn't include 'up next'; comes from a separate
endpoint). Kotlin gets empty list for now — RelatedRow handles it.
Type quirks vs my initial guesses (caught by cargo check):
- details.duration is u32, not Option<u32>
- channel is split into channel_id + channel_name, not a struct
- like_count doesn't exist at this query depth
- VideoFormat::Webm (lowercase mb), VideoCodec::Avc1 (not H264)
- video_only is a separate vec (video_only_streams), not a bool flag
