Input & UI

  • In-stream on-screen keyboard (Shift/Ctrl/Alt sticky, chords) replacing the old IME path
  • Settings modal with tabs: stream quality, controls, region, language, color depth, session timer, per-game profiles
  • Controls hint + in-stream controls modal with Vita front/back diagrams
  • Session timer overlay driven by membership tier (Free / Priority)

Launch & Free tier

  • Queue ads lifecycle (Start / progress / Finish) so Free sessions no longer time out waiting on ads
  • Server / region picker with latency probes and queue stats before launch
  • Provider-aware CloudMatch base URL discovery
  • Multi-zone active-session cleanup (survives one zone flaking)

Streaming

  • Async H.264 decode path, jitter-adaptive RTP reorder
  • Adaptive bitrate ceiling, 16-bit default color depth, frame pacing improvements
  • File logging for stream diagnostics

Packaging & i18n

  • Lighter Japanese font subset (~1.8 MB) for catalog titles
  • Vita APP_VER=00.32 (keep in sync with Cargo version)
  • EN/ES strings for the new settings and launch UI

Reliability follow-ups

  • Fix settings cache self-deadlock on first prefs write
  • Persist membership tier after token refresh without clobbering refreshed tokens
  • Avoid cloning full settings on the per-frame control path
  • UTF-8-safe ad id log truncation

Merge Risk: 🔴 Critical · up to e8319

This PR changes streaming, settings, networking, and rendering behavior, but the current version can hang during preference updates, send authentication tokens to an unsafe endpoint, corrupt decoder state on supported firmware, and degrade or fail streaming under error conditions. It is not merge-ready and should be blocked until the concrete correctness and security issues are fixed.

Extract the 15 s fallback duration into one constant.

progress_pct at Line 250 and tick at Line 282 each hardcode 15_000 as the fallback for a missing length_ms. The two values must stay equal, otherwise the progress bar and the finish threshold disagree. Define the default once.

- Around line 1381-1395: Avoid saving membership_tier from the stale
tokens_for_tier snapshot captured before token maintenance. Restructure the
tokio::spawn membership-resolution flow so it runs after refresh/save work and
updates credentials through the single token-state owner, such as returning
updated AuthTokens to App or using a serialized shared update operation. Add a

verifies refreshed access token, refresh token, client token, and expiry are
preserved.

- Around line 689-695: Move the membership-tier lookup out of the streaming

Connect VideoPlayer to the playback backend.

VideoPlayer stores only lifecycle and timing state. load_url only stores a URL, and play only changes PlayerState. The player does not create or drive VideoDecodeWorker, provide media input, or expose decoded output. Calls through this public API cannot play H.264 video.

Connect this type to the decode and rendering pipeline. Alternatively, make it an internal state model and remove the hardware-player claim from its documentation.

Reset the duration when loading new media.

A second load_url call retains the prior media duration. The player can then finish too early or too late before metadata updates the duration. Reset duration when the URL changes.

When delta crosses the end of a loop, this code resets position to zero. It discards the elapsed time after the boundary. Use the remainder of position / duration when looping.

Clear app_patching after a normal poll response.

Line 606 sets app_patching to true for a patching response. Lines 723-732 do not reset it after a successful non-patching response. The launch UI checks this flag before ad and queue state, so it can continue to show the patching message until the launch exits this view.

139-214: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

The AVCDEC sysmodule reference leaks on every early bail after a successful load.

sceSysmoduleLoadModule succeeds first. After that, five paths can bail before Ok(Self { .. }) is returned:

  • sceVideodecSetConfigInternal failure (Line 169)
  • sceAvcdecSetDecodeMode failure (Line 174)
  • sceVideodecQueryMemSizeInternal failure (Line 186)
  • CodecEngineMemory::allocate failure (Line 192)

Only the sceVideodecInitLibraryWithUnmapMemInternal path (Lines 207-214) unloads the module. On the other paths AvcdecLibrary is never constructed, so its Drop never runs and the sysmodule reference stays held.

submit_queued_access_unit in src/streaming/video/worker.rs (Lines 280-289) recreates the decoder after every decode error, so a repeating failure leaks one module reference per attempt.

Route all post-load failures through a single unload path.

🛡️ Proposed fix: unload once via a closure
+            let unload_on_error = |ret_msg: String| -> anyhow::Error {
+                if module_loaded {
+                    unsafe { sceSysmoduleUnloadModule(SCE_SYSMODULE_AVCDEC) };
+                }
+                anyhow::anyhow!(ret_msg)
+            };
+
             let config_ret = unsafe {
                 sceVideodecSetConfigInternal(SCE_VIDEODEC_TYPE_HW_AVCDEC, INTERNAL_CODEC_CONFIG)
             };
             if config_ret < 0 {
-                bail!("sceVideodecSetConfigInternal failed: {config_ret:`#x`}");

+                )));
             }

Apply the same pattern to the sceAvcdecSetDecodeMode, sceVideodecQueryMemSizeInternal, and CodecEngineMemory::allocate failures.

Bound the cleanup loop by wall-clock time, not only by round count.

The cap moved from 2 to 15. Each round runs send_request, then stop_conflicting_sessions, which lists sessions across every base and then calls wait_for_sessions_to_clear. That helper sleeps CHECK_INTERVAL (3 s) up to MAX_CHECKS (8) times. Fifteen rounds can therefore hold the launch for about six minutes of sleeps alone, plus the request time, before the player sees any error.

Add a deadline check around the loop so the launch fails within a predictable budget.

The IYUV pitch check can retry a format that just failed and then abort the session.

The new fallback chain can reach format == VideoPixelFormat::Iyuv through the BGR565 failure branch at Lines 173-179. The pitch check that follows runs whenever !force_iyuv && format == Iyuv, and its remedy is create_targets(PixelFormatEnum::BGR565)?.

On that path BGR565 creation already failed. The retry very likely fails again, and the ? propagates the error out of ensure_direct_video_output instead of keeping the IYUV textures that were created successfully. The stream then ends because the pitch was not ideal, even though a usable format was in hand.

Track how IYUV was selected, and treat a pitch mismatch reached through the fallback as acceptable.

A missing pixel format leaves the drain loop polling every millisecond.

When direct_output.pixel_format() returns None, this path returns without changing output_state.picture_pending. The flag stays true, so run_decode_loop re-arms after(PICTURE_POLL_INTERVAL) and calls drain_picture again 1 ms later. The cycle repeats until the render thread calls set_pixel_format.

The decode thread is pinned to the media core, so this spins that core at roughly 1 kHz while the surface is still being set up, and again after every detach_direct_video_output.

The other two early returns above clear picture_pending for exactly this reason. Handle the unregistered-format case the same way, or gate on decoder_ready.

ColorDepth::from_key falls back to 32-bit, against the documented default.

The doc comment at Line 276 states the default is 16-bit, and default_color_depth() writes "16". from_key maps every unrecognized key to ThirtyTwoBit. #[serde(default = "default_color_depth")] covers only a missing field, so a stored color_depth of "" or any other unexpected value silently selects 32-bit and doubles every video texture.

An unknown preferred provider skips the defaultProvider fallback.

The else if chain evaluates the default_provider branch only when login_preferred_providers is empty. If the first preferred name does not match any endpoint, the lookup yields None and selection falls straight through to providers[0], the lowest-priority-number entry. The server-supplied default is ignored.

args_fingerprint can produce the same key for different argument sets.

Decide whether the blocking lock_decode_target still has a caller.

try_lock_decode_target replaces the blocking path in the worker drain. lock_decode_target now carries #[allow(dead_code)], which suppresses the warning but leaves the older condvar-based path, its MAX_PENDING_TEXTURE_WAIT timeout, and its pending-frame-overwrite fallback in the file with no caller.

Two behaviours differ between them: the blocking version overwrites an undisplayed pending frame when it times out, while try_lock_decode_target simply returns None. Keeping both invites the wrong one being picked later.

If the blocking variant is a deliberate fallback, add a comment that states when it should be used. Otherwise remove it together with the now-unused wait constant.

The idle-video PLI block still contains the inline implementation that send_pli_if_needed replaces.

The change summary states this block now uses the shared PLI dispatch, but the code here still holds the full inline copy: the same PLI_MIN_INTERVAL check, the same write_rtcp with PictureLossIndication, the same last_pli_sent and pli_sent_count updates, and the same keyframe_requests increment.

Two independent copies of the rate limit now exist. They share last_pli_sent, so the limit still holds today, but any change to the send policy must be applied twice.

One behaviour difference blocks a purely mechanical swap: this block gates on is_connected.load(Ordering::Relaxed), which send_pli_if_needed does not check. Keep that gate at the call site.

Consider gating the repaint rate while a stream is live.

The loop now builds the UI, tessellates, paints, and presents on every iteration, paced to TARGET_FRAME_TIME. The previous reactive-repaint and idle-skip path is gone. In a menu that is the intended behaviour and it fixes the input latency the comment at Lines 21-24 describes.

During streaming the cost lands differently. FrameStats and the peer status line both show that the decode thread is pinned to the media core while this loop drives constant CPU work and a canvas.present() per 16 ms. The overlay is mostly static during play, so most of that work redraws identical pixels while competing for memory bandwidth with texture uploads and picture retrieval.

Two options that keep the menu responsive:

  • While AppState::Streaming is active and no overlay is visible, repaint the egui layer at a lower rate and keep presenting the video texture every frame.
  • Use full_output.viewport_output repaint hints to skip the tessellate and paint phases when egui reports no change, while still polling input every iteration.

The existing FRAME_STATS_INTERVAL log already records iterations against painted frames, so the effect of either change is measurable from the frame-stats file.

The AU payload buffer is not actually reused after a successful assembly.

std::mem::take(buf) moves the Vec out on the Complete path. self.assemble_buf is then an empty Vec with no capacity, so the next successful assembly allocates again. Reuse only happens after Pending or Invalid outcomes.

If reuse across successful frames is the goal, copy out instead of taking, or swap in a second buffer.

♻️ Option: copy out and keep the capacity
         *depacketizer = H264Packet::default();
         FrameAssembly::Complete {

+            data: buf.clone(),
             marker_sequence,

A clone costs one allocation too, so the clearer fix is to reword the comment at Line 111 to state that reuse applies to retry paths only.

A recycled pooled texture keeps the previous icon's pixels outside the updated rectangle.

finish_icon_upload updates only Rect::new(0, 0, width, height) of a 64×64 texture taken from icon_free_pool. For an icon smaller than 64×64 the remaining texels still hold the previous icon.

uv_scale plus the clamp in sdl_vertex keeps sampling inside the valid sub-rectangle, so the stale region is not drawn directly. SDL_RENDER_SCALE_QUALITY is set to 1 in src/shell/surface.rs, so linear filtering samples one texel past the clamped edge and blends the old icon's colour into the new icon's border.

Clear the pooled texture before reuse, or pad the update by one texel of edge-replicated colour.

RETRIES_PER_FRAME has no effect on the retry budget.

retry_budget is RETRIES_PER_FRAME.min(NEW_TEXTURES_PER_FRAME) + 1. With NEW_TEXTURES_PER_FRAME = 1, the min collapses to 1 for any RETRIES_PER_FRAME >= 1, so the budget is always 2. Raising RETRIES_PER_FRAME to 4 or lowering it to 2 changes nothing.

The retry loop then also performs its own creations without checking new_creations against NEW_TEXTURES_PER_FRAME, so a frame can create up to three textures: one font, plus two from retries.

State the intended budget directly, and apply the creation cap inside the retry loop.

queue_full can count twice for one access unit.

When self.access_units.len() >= pending_limit and the channel is also physically full, the first block increments queue_full and drops one entry, then try_send still returns Full, and the second block increments queue_full again for the same access unit. At 60 FPS pending_limit equals AU_QUEUE_CAP, so both conditions coincide.

src/gfn/peer.rs compares the queue_full rate against QUEUE_FULL_RECOVERY_THRESHOLD (5.0 per second) to decide whether to send a recovery PLI. Double counting halves the real threshold, so recovery PLIs fire on roughly half the intended drop rate.

Count the soft-limit drop and the hard-full drop as one event.

♻️ Proposed fix: count once per rejected access unit
         if self.access_units.len() >= pending_limit {

active_profile clones the whole settings tree on the per-frame input path.

load_or_init_settings() returns an owned AppSettings, so every call clones the game_profiles BTreeMap and every String field. active_profile runs from trigger_intensity(), stick_zones(), and rear_touch_mode(), which the doc comment at Line 66 states are read from per-frame gamepad polling. That allocates several times per frame on the Vita, which is the cost with_cached_settings was added to remove.

Read through with_cached_settings and clone only the profile.

The same clone applies to the other new getters that call load_or_init_settings() directly: rear_touch_mode (Line 573), region (Line 589), game_language (Line 713), session_timer_enabled (Line 722), and trigger_swap_enabled (Line 731). Switch them to with_cached_settings as well.

♻️ Proposed fix for `active_profile`
 fn active_profile() -> Option<GameProfile> {
     let app_id = active_game()?;
-    load_or_init_settings().game_profiles.get(&app_id).cloned()
+    with_cached_settings(|s| s.game_profiles.get(&app_id).cloned())

The text_with cache has no bound and no eviction.

The cache key includes the formatted argument values. Callers pass values that change at runtime. src/app/mod.rs:291 forwards any impl ToString, and handle_command passes error strings, region names, and session-time values. Each distinct value inserts a new Rc<str> that is never removed, so the map grows for the whole process lifetime. On the Vita this is a steady memory leak during a long session.

Cap the entry count and clear the cache when the cap is reached.

🛡️ Proposed fix: bound the cache
     pub fn text_with<'a>(&self, id: &'static str, args: FluentArgs<'a>) -> Rc<str> {
         let fingerprint = args_fingerprint(&args);
+        /// Formatted strings are cheap to rebuild, so a full clear is enough to bound growth.
+        const MAX_ENTRIES: usize = 512;
         thread_local! {
             static CACHE: RefCell<HashMap<(Locale, &'static str, String), Rc<str>>> =
                 RefCell::new(HashMap::new());
         }
         CACHE.with(|cell| {
             let key = (self.locale, id, fingerprint);
             if let Some(cached) = cell.borrow().get(&key) {
                 return Rc::clone(cached);
             }
             let resolved: Rc<str> = self.text_with_args(id, Some(&args)).into();
-            cell.borrow_mut().insert(key, Rc::clone(&resolved));
+            let mut cache = cell.borrow_mut();
+            if cache.len() >= MAX_ENTRIES {
+                cache.clear();
+            }
+            cache.insert(key, Rc::clone(&resolved));
             resolved
         })
     }

Run the following script to measure how many distinct argument values reach text_with:

#!/bin/bash
# Description: List every formatted-translation call site and the argument expression it passes.
set -euo pipefail

# tr1/tr2 helpers and direct text_with callers.
rg -nP --type=rust -C2 '\b(tr1|tr2)\s*\(' 
rg -nP --type=rust -C2 '\.text_with\s*\('

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift

The pending queue is bounded by entry count, not by bytes.

enqueue_pending stores pixels: scratch.clone(), a full RGBA copy of the deferred image. MAX_PENDING_UPLOADS caps the queue at 12 entries, but says nothing about their size.

For the icon path at Line 284 each entry is at most 64×64×4 = 16 KB, so the queue stays under about 200 KB. The general path at Line 302 has no size limit: one 512×512 cover is 1 MB, and twelve of them is 12 MB held in the pending map. This painter defers uploads precisely because texture creation is failing for lack of memory, so retaining megabytes of pixel copies works against the goal.

defer_or_give_up re-clones the same payload on each retry attempt, up to MAX_UPLOAD_ATTEMPTS of 8, which keeps the copy alive for as long as the backoff runs.

Add a byte budget alongside the entry count, and evict the largest non-font entry when the budget is exceeded.

decode_us and target_wait_us are never written, so both latency readouts report zero.

metrics.decode_calls increments at Line 297 and metrics.target_wait_calls increments at Line 360, but nothing writes metrics.decode_us or metrics.target_wait_us.

src/gfn/peer.rs derives its status line from exactly those pairs:

  • avg_decode_ms = decode_us delta / decode_calls delta
  • avg_wait_ms = target_wait_us delta / target_wait_calls delta

With the microsecond counters stuck at zero, the diagnostic line always prints dec:0.0ms wait:0.0ms. src/streaming/video/mod.rs documents decode_us as "their cumulative wall time" and target_wait_us as "Cumulative time spent acquiring a decode texture", so the contract is stated but not fulfilled. For a change whose purpose is diagnosing stalls, this removes the two most useful numbers.

🐛 Proposed fix: record the elapsed time next to each counter
+    let submit_started_at = std::time::Instant::now();
     let submit_result = catch_unwind(AssertUnwindSafe(|| {
         decoder
             .as_mut()
             .expect("decoder recreated above")
             .submit_access_unit(&access_unit.data)
     }));
     metrics.decode_calls.fetch_add(1, Ordering::Relaxed);
+    metrics.decode_us.fetch_add(
+        submit_started_at.elapsed().as_micros() as u64,
+        Ordering::Relaxed,
+    );
+    let target_wait_started_at = std::time::Instant::now();
     let Some(direct_target) = direct_output.try_lock_decode_target() else {
         metrics.target_stalls.fetch_add(1, Ordering::Relaxed);
         output_state.picture_pending = true;
         return;
     };
     metrics.target_wait_calls.fetch_add(1, Ordering::Relaxed);
+    metrics.target_wait_us.fetch_add(
+        target_wait_started_at.elapsed().as_micros() as u64,
+        Ordering::Relaxed,
