Replaces the rustypipe-backed extraction with calls into the new
NPE-port crate. The UniFFI surface Kotlin sees is unchanged:
suspend fun search(query: String): List<SearchItem>
suspend fun streamInfo(input: String): StreamInfo
suspend fun channelInfo(input: String): ChannelInfo
fun initLogging() // also wires the strawcore-core Downloader
fun helloFromRust(name: String): String
rust/strawcore/
* Cargo.toml — dropped rustypipe + rquickjs-sys direct dep;
added strawcore-core path dep (../../../strawcore)
* src/error.rs — From<strawcore_core::ExtractionError>, mapping
ContentUnavailable variants to typed
StrawcoreError cases (AgeRestricted, GeoRestricted,
Private, RequiresLogin) instead of bucketing all
to Extractor
* src/runtime.rs — Once-guarded ReqwestDownloader init via
NewPipe::init_full
* src/search.rs — search() spawn_blocks core search_extractor::search
against SearchFilter::Videos
* src/stream.rs — stream_info() resolves URL → video_id via
strawcore_core::linkhandler::stream, then
spawn_blocks core stream_extractor::stream_info,
then maps StreamInfo → wrapper DTOs (combined/
video_only/audio_only/dash/hls)
* src/channel.rs — channel_info() parses input via
strawcore_core::linkhandler::channel (handle /
custom-url / legacy-user resolution lives in
core), then spawn_blocks core channel::channel_info
Build verified: wrapper compiles linking strawcore-core, uniffi-bindgen
generates Kotlin bindings with the same suspend fun + data class
surface Kotlin already consumes. Android NDK cross-compile + APK + on-
device smoke pending (needs build-host container).
This commits onto rollback/vc18-back-to-NPE — the existing Kotlin code
still calls NewPipeExtractor directly. Switching the Kotlin side to
consume the rust wrapper is a separate cutover.
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
