Adds a Cast button to Movie, TV and Downloads pages plus a device-picker
modal and mini-controller. Streams anime mp4, anime Sl-Hls, vidsrc /
videasy / 2embed HLS captures, and completed local downloads to any
Chromecast-built-in device (incl. XGIMI Android TV projectors) or DLNA
renderer on the LAN.
Highlights
- New main-process module src/ipc/cast.js
- Discovery: bonjour-service (_googlecast._tcp) + dlnacasts3 SSDP
- LAN-routable HTTP server bound 0.0.0.0:<random>
- /file/:token range-supported local file serve
- /proxy/:token header-injecting proxy with on-the-fly HLS playlist
rewriting (segments + EXT-X-KEY / EXT-X-MAP child tokens) so
receivers always speak to a Referer-injecting proxy
- /sub/:token VTT with CORS, inline SRT->VTT conversion
- Single active session (mirrors PIP). castv2-client for Chromecast,
dlnacasts3 for DLNA. Clean disconnect on before-quit.
- Preload bridge: cast:* IPC surface modeled on existing PIP naming.
- Renderer
- useCast() hook (src/utils/useCast.js) for device list + session state
- CastPickerModal with recent / available device lists, CAST/DLNA badges
- CastMiniController with play/pause/scrubber/CC toggle/volume/stop
- CastIcon + CastingIcon in Icons.jsx
- Wired into MoviePage, TVPage, DownloadsPage; Sidebar status via
the global mini-controller variant
- Settings: new "Cast & Devices" section (auto-discover, include-DLNA,
auto-stop, preferred device, rescan, limitations notes).
- Storage: CAST_* keys for the above preferences.
Dependencies
- castv2-client (Chromecast control)
- bonjour-service (mDNS for _googlecast._tcp)
- dlnacasts3 (DLNA SSDP + AVTransport)
All pure JS, no native deps.

Looks interesting, I suppose you have a Device to test this? Because I do not xD... Also, do you understand the Code you shared here? |

yes, I am using it on my projectors and my TV :) ;) |

I am just adding some controls, will push shortly |

…dded controls Session / stop reliability - tearDown quits the DefaultMediaReceiver via client.stop(player) before closing the socket (1.5s fallback), so Stop returns the device to its home screen instead of leaving the cast splash up. - On Chromecast load failure, tear down the session + emit session-ended so the receiver doesn't sit on the splash and the UI resets. - Force-HLS hint: hlsRemote parent token and rewritten variant-playlist child tokens carry isHls so a mislabeled / extensionless m3u8 is still rewritten through the proxy (segments keep the injected Referer). In-app playback while casting - When a device is connected, the in-app <webview> is suspended (src -> about:blank) so playback doesn't double up with the receiver. A centred overlay shows "Playing on <device>" with the full controller. Device controls - CastMiniController gains a stacked "modal" variant (device label, seek, back/forward 10s, play/pause, subtitle toggle, volume, stop) embedded directly in the casting overlay and in the picker popup when connected. Discovery noise / efficiency - Discovery is on-demand: pages no longer scan on mount. The picker and the Settings > Cast section start discovery on open and stop it on close. - The connected device is tracked independently of the live discovery list, so controls keep working while discovery is stopped. - DLNA SSDP is gated by the "Include DLNA" setting and throttled to once per 8s; the dlnacasts "[DLNACASTS] querying ssdp" debug line is silenced.

Discovery (root cause of "no devices found")
- Bind the mDNS socket to the LAN interface (new Bonjour({ interface }))
via getLocalIPv4(). On machines with an active VPN or a second adapter
the default bind landed on the wrong interface and received zero
responses, so no Chromecast / Chromecast-built-in (e.g. XGIMI) devices
ever appeared. Rebuild the instance if the routable IP changes (VPN
toggled / network switched) so discovery recovers without a restart.
- Keep the mDNS browser alive for the session and re-query on reopen
instead of tearing it down on every picker/settings close (the teardown
made already-found devices disappear).
- Restore page-mount discovery (autoDiscover) now that it's cheap: passive
mDNS listener, DLNA SSDP gated by setting + throttled to 8s, and the
dlnacasts "[DLNACASTS] querying ssdp" debug line silenced.
- Hold the "scanning" state for a ~5s response window so the picker shows
"Scanning the network…" instead of flashing "No devices found" (the
start-discovery IPC resolves immediately while responses trickle in).
Serving correctness (from code review)
- getLocalIPv4 is now subnet-aware: when a receiver is connected it picks
the local interface on the receiver's subnet, falling back to a
preferred adapter, then any non-internal IPv4, then loopback. Prevents
handing the receiver an unreachable URL on multi-NIC setups.
- Dedup proxy tokens by target+referer (makeProxyToken) so HLS playlist
re-fetches (seeks/variant switches) reuse tokens instead of growing
_serveTokens unbounded; gcServeTokens prunes the dedup index too.

The in-app player paused when the laptop display slept or the window was
occluded because the main window used backgroundThrottling: true and
nothing held a power-save blocker (pre-existing, unrelated to casting).
- Hold powerSaveBlocker("prevent-display-sleep") while in-app playback is
active; release on pause/stop, on window close, and on app quit.
- Release the blocker while casting — playback then lives on the receiver
and the laptop is free to sleep.
- Set backgroundThrottling: false on the main and pop-out windows so
occlusion / alt-tab no longer throttles or pauses media.
Wired via a new playback-keepawake IPC + setPlaybackKeepAwake preload
bridge, driven from MoviePage/TVPage on `playing && !cast.currentDevice`.
