Direct-play seeks on Tizen were failing on every title (resume from 0, "Player seek to failed"). This PR adds the diagnostics that found the cause, moves to videohole 0.6.0, and documents the fix, which is proxy config rather than app code.

Root cause

The TV's native player (capi-media-player) decides from the first response whether an HTTP source is seekable. HAProxy lowercases response header names over HTTP/1 (accept-ranges, content-range, ...), so the player treated the stream as unseekable and rejected every player_set_play_position with Invalid state, in READY and PLAYING alike. Server logs showed one Range: bytes=0- request per session. The same stream fetched straight from the backend (canonical-case headers) seeks fine on the TV. The fix is h1-case-adjust in HAProxy; see the new "Tizen troubleshooting" section in flutter/README.md.

Changes

  • Vendor video_player_videohole 0.6.0 (upstream: Dart FFI, pending-seek coalescing) as a path fork in flutter/packages/video_player_videohole. The pristine copy is its own commit, so the patch diffs cleanly.
  • Fork patch:
    • seekTo failures carry the native reason and player state (new ffi_get_last_seek_error), e.g. player_set_play_position(1008161) failed: Invalid state (ret=0xfe6c0022, state=READY). This reaches reportDiagnostic through the existing PlatformException handling.
    • Plugin INFO/WARN/ERROR logs are also written to stderr, because retail TVs block dlog and flutter-tizen forwards stderr over --tizen-logging-port.
    • Stream URL query strings (st= token) are redacted in plugin logs.
  • Tizen dependency bumps: shared_preferences_tizen ^2.3.5, flutter_secure_storage_tizen ^0.1.6, device_info_plus_tizen ^1.4.3, plus in-range transitive upgrades. The lockfile also gains the previously missing path_provider_tizen entry. Still held back: riverpod 3 and flutter_secure_storage 11, pinned by prairie_core's constraints because it's shared with the webOS build (Dart 3.10).
  • Docs: README troubleshooting (symptom, cause, HAProxy fix, how to verify, other proxies) and how to get native logs from a retail TV.

The branch also contains the earlier 0.5.9-based patch commits, superseded by the 0.6.0 port. Squash-merging is fine.

Testing

  • flutter-tizen analyze: no issues.
  • Release TPK built, installed and run on a QN55QN700BFXZA (Tizen 6.5).
  • Behind HAProxy: seek reasons and native logs came through as intended.
  • With HAProxy bypassed: resume and manual seeks both return "Seek completed".

Not covered

  • Remote playback through Cloudflare. Cloudflare was seen sending content-range in lowercase; not yet tested on a TV.

Verbatim copy from pub.dev so the following patch diffs cleanly.

Direct-play seeks fail with a bare "Player seek to failed"; the real
reason from player_set_play_position only went to dlog, which retail
TVs block. Patch the vendored plugin to:

- return the native error, ret code and player state in the SeekTo
  FlutterError message (reaches reportDiagnostic via PlatformException)
- tee LOG_INFO/WARN/ERROR to stderr, which flutter-tizen forwards over
  --tizen-logging-port

Point prairie_tizen at the path fork. The lockfile also picks up the
previously missing path_provider_tizen entry.

videohole 0.6.0 serializes seeks and guards native overlap; recording it
in the reason tells us whether that upgrade would address our failures.

Replaces the 0.5.9 copy (and its patch) with the verbatim pub.dev 0.6.0
release; the Prairie patch is re-applied on top in the next commit.

0.6.0 moved to Dart FFI, so the reason now travels through a new
ffi_get_last_seek_error() and is appended to the FFI_SEEK_TO_FAILED
PlatformException message. 0.6.0's own is_seeking_ guard reports as
"seek already in progress", which replaces our seek_in_flight flag.

shared_preferences_tizen ^2.3.5, flutter_secure_storage_tizen ^0.1.6,
device_info_plus_tizen ^1.4.3, plus in-range transitive upgrades.
Remaining outdated packages (riverpod 3, flutter_secure_storage 11) are
held by prairie_core, which is shared with the webOS Dart 3.10 build.

…V logging

Direct-play seeks failed with "Invalid state" because HAProxy lowercases
response header names and the TV's native player then treats the stream
as unseekable. Document the h1-case-adjust fix, how to verify it, and how
to get native plugin logs from a retail TV.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 49a0f

Prairie’s configured playback path avoids DRM, but the vendored package still exposes DRM paths with lifetime hazards and synchronous license processing. Fix or explicitly accept these package-level limitations before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 49a0f

The reviewed changes are concentrated in the Tizen client. Playback and license URL query strings are redacted before native logging, and the current app does not configure DRM. No introduced security attack path was established on that configured playback path. Some optional DRM lifetime behavior and the comparison with the previous package remain unresolved.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is the Tizen client’s native playback and diagnostic output. A consumer explicitly enabling DRM can additionally reach configured license servers and the license-callback bridge. The current Prairie construction does not establish that optional exposure.

Trust Boundaries and Controls

  • observed — The optional native license transaction enables TLS peer and host verification. Its manual redirect loop preserves HTTPS URLs rather than unconditionally downgrading them, but does not enforce an HTTPS-only or same-origin destination policy. This behavior is unchanged between the pristine 0.6.0 copy and the reviewed diagnostic patch; equivalence with the prior published dependency remains unestablished.
  • observed — Raw cookie, custom-header, and composed SOAP logging exists in the helper, but the checked native caller passes null cookie and extension arguments. Together with Prairie’s omission of DRM configuration, this limits the evidence for credential disclosure through those newly stderr-enabled sinks.

Resilience and Maintainability Implications

  • inferred — Optional DRM teardown has an unresolved ownership guarantee: cancelling scheduled GLib work does not by itself establish that previously issued Flutter license replies cannot use a released manager or session. Native callback quiescence and session-identity validation were not established. The diagnostic patch leaves these mechanisms unchanged relative to pristine 0.6.0, and the current Prairie caller does not enable this path.

Hardening Proposals

  • proposed — Before enabling DRM for additional callers, explicitly bind asynchronous replies to live session ownership and document callback-quiescence guarantees. Constrain license destinations and keep credential-bearing headers and bodies out of exported diagnostics.

header data as a C string. In GetRedirectLocation, match Location only at the
start of a header line, excluding names such as Content-Location.

member, populate its fields, and pass its address to DMGRSecurityInitCompleteCB.
Declare and initialize the member in DRMManager.
- Around line 245-252: Update DrmManager::OnChallengeData to log only
message_length; remove the binary message argument and the `%s` format specifier
so logging never reads beyond the challenge buffer.
- Around line 325-338: Update the async license-result handler passed to

Sensitive Data Exposure

Exploitability: Difficult
CWE: CWE-532 — Insertion of Sensitive Information into Log File

Redact DRM URLs and credentials before logging them. license_server_url_ is read from drm_configs()["licenseServerUrl"], logged directly by DrmManager, and passed to DrmLicenseHelper, which logs http_url without redaction. SetHttpHeader also logs raw cookie and custom-header values. Redact URL query parameters and remove credential values from INFO logs.

Fixed in 49a0f4c. License URLs are now logged through RedactUriForLog (query stripped) in both DrmManager and DrmLicenseHelper. The cookie and custom-header values are logged at DEBUG, which only goes to dlog (blocked on retail TVs) and isn't teed to stderr, so they don't leave the device.

@JonahMMay, thanks for clarifying the DEBUG logging behavior. I verified that both license URL logs now use RedactUriForLog. I also confirmed that LOG_DEBUG is not copied to stderr.

However, verification of the credential fix failed. In flutter/packages/video_player_videohole/tizen/src/drm_license_helper.cc, these logs remain:

  • Line 362: LOG_INFO prints the cookie value.
  • Line 371: LOG_INFO prints the custom-header value.
  • Line 601: INFO_CURL_HEADERS(headers) prints the full header list through LOG_INFO.

These calls still write credential values to stderr. Please remove or redact those values, including the header-list output, then request another check. This finding remains open.

JonahMMay reports that retail Tizen TVs block dlog. Distinguish DEBUG-only logs from stderr logs when reviewing sensitive-data exposure in this fork.

Learning: Prairie does not play DRM content or pass drmConfigs. Its vendored video_player_videohole 0.6.0 fork at flutter/packages/video_player_videohole limits patches to app-reachable paths and issues introduced or worsened by the stderr log tee, to keep upstream resynchronization simple. Unused upstream DRM lifetime and threading issues should be reported upstream rather than treated as required fork changes.

The stderr log tee now ships plugin logs off the device, so:
- redact query strings in DRM license URL logs (shared RedactUriForLog)
- log only the length of the binary DRM challenge (was %s over-read)
Also fix int64_t window-geometry format specifiers (UB) and guard the
live-duration parse against malformed responses.

DRM lifetime/threading findings are upstream issues on paths the app
does not use (no DRM content); left unchanged to stay close to upstream.
