From 517543f574a984d340734def8d111103d0460b8a Mon Sep 17 00:00:00 2001 From: professorDeveloper <108933534+professorDeveloper@users.noreply.github.com> Date: Tue, 10 Nov 2026 10:13:05 +0500 Subject: [PATCH] Player: a server that cannot seek is a notice, not an error UHD Movies' Google links ignore byte ranges. mpv reports "Cannot seek in this stream" on every skip, and the page treated it as a playback error, reopening the url at 0:00. Viewers saw a 30 s skip start the film over. The mpv controller now raises seekRefused instead of an error, the film plays on, and the player says once that this server cannot skip, with Change server when the title has other servers. --- assets/translations/ar.json | 1 + assets/translations/ckb.json | 1 + assets/translations/de.json | 1 + assets/translations/en.json | 1 + assets/translations/es.json | 1 + assets/translations/fr.json | 1 + assets/translations/hi.json | 1 + assets/translations/id.json | 1 + assets/translations/ku.json | 1 + assets/translations/nl.json | 1 + assets/translations/pt.json | 1 + assets/translations/ru.json | 1 + assets/translations/tr.json | 1 + assets/translations/uz.json | 1 + assets/translations/vi.json | 1 + assets/translations/yue.json | 1 + lib/core/player/media_controller.dart | 18 ++++++++++++++++++ lib/core/player/playback_readiness.dart | 9 +++++++++ .../detail/presentation/pages/player_page.dart | 1 + .../presentation/pages/player_page.media.dart | 2 ++ .../presentation/pages/player_page.toast.dart | 16 ++++++++++++++++ test/core/player/playback_readiness_test.dart | 11 +++++++++++ 22 files changed, 73 insertions(+) diff --git a/assets/translations/ar.json b/assets/translations/ar.json index a37719b0..56175953 100644 --- a/assets/translations/ar.json +++ b/assets/translations/ar.json @@ -408,6 +408,7 @@ "subtitle_preview_text": "نصٌّ تجريبيٌّ لمعاينة شكل الترجمة", "server": "الخادم", "change_server": "تغيير الخادم", + "cannot_seek_server": "لا يمكن التقديم على هذا الخادم. شاهد من البداية أو اختر خادمًا آخر.", "stream_not_found": "يُخفي هذا المصدر بثّه خلف مشغّل محمي. جرّب مصدراً آخر، أو افتحه في متصفّحك.", "subtitle_translation": "ترجمة النصوص", "auto_translate": "الترجمة التلقائية", diff --git a/assets/translations/ckb.json b/assets/translations/ckb.json index 5073368a..676b6d34 100644 --- a/assets/translations/ckb.json +++ b/assets/translations/ckb.json @@ -422,6 +422,7 @@ "subtitle_preview_text": "ڕێوییە قاوەییە خێراکە بەسەر سەگە تەمەڵەکەدا باز دەدات", "server": "سێرڤەر", "change_server": "گۆڕینی سێرڤەر", + "cannot_seek_server": "لەم سێرڤەرەدا ناتوانرێت بازبدرێت بۆ پێشەوە. لە سەرەتاوە سەیری بکە یان سێرڤەرێکی تر هەڵبژێرە.", "stream_not_found": "ئەم سەرچاوەیە پەخشەکەی لە پشت لێدەرێکی پارێزراو شاردۆتەوە. سەرچاوەیەکی تر تاقیبکەرەوە، یان لە وێبگەڕەکەتدا بیکەرەوە.", "subtitle_translation": "وەرگێڕانی ژێرنووس", "auto_translate": "وەرگێڕانی خۆکار", diff --git a/assets/translations/de.json b/assets/translations/de.json index 78d358cc..70ad67ef 100644 --- a/assets/translations/de.json +++ b/assets/translations/de.json @@ -408,6 +408,7 @@ "subtitle_preview_text": "Franz jagt im komplett verwahrlosten Taxi quer durch Bayern", "server": "Server", "change_server": "Server wechseln", + "cannot_seek_server": "Auf diesem Server kann man nicht vorspulen.
