PrismCast v1.7.0 is here. Three headline features in this release:
Hardware-accelerated HEVC capture. When PrismCast detects that Chrome is using GPU-accelerated rendering, it now automatically captures in HEVC/H.265 instead of H.264 — delivering higher quality at lower bitrates with significantly reduced CPU usage. No configuration needed. Detection and codec switching are fully automatic and seamless. If you have a GPU available, you're already benefiting.
Browse Channels and Provider Setup. Two new wizards that completely rethink how you discover and manage your channel lineup. Browse Channels lets you pick a provider and see every available channel at a glance — with logos pulled from your Channels DVR library and indicators showing whether each channel is new, already active, or available via another provider. Add, switch, or remove channels in bulk. Provider Setup is a guided first-run experience that walks you through selecting your streaming providers, signing in, and building your initial channel lineup. It appears automatically on first visit and can be re-run anytime from the channels tab.
Cox Contour TV is PrismCast's ninth builtin provider. Thanks to @babsonnexus for the collaboration getting Cox up and running.
Beyond the headlines, there's more in this release:
-
Per-channel HDHomeRun/Plex lineup control — choose which channels appear in the HDHomeRun lineup for Plex on a per-channel basis. A new opt-in HDHR column in the channels table provides inline checkboxes for quick toggling, and a bulk toggle in Quick Actions lets you include or exclude all channels at once. Channels excluded from the HDHR lineup remain available in the M3U playlist for Channels DVR.
-
Inline editing for channel numbers and station IDs — click any Number or Station ID cell in the channels table to edit it in place. Changes save on Enter or when you click away, and Escape cancels.
-
Auto-number channels — assign sequential channel numbers to all visible channels based on the current sort order, or clear all channel numbers at once. Found in the Quick Actions menu.
-
Resolution degradation detection refinements — improved detection accuracy and clearer log messages when a provider drops to a lower resolution.
-
Hallmark site provider entries removed — Hallmark no longer offers direct streaming from their website. Hallmark, Hallmark Family, and Hallmark Mystery remain available through all TV provider variants (Cox, DirecTV, Hulu, Spectrum, Xfinity, YouTube TV).
-
Numerous fixes — provider filter now correctly applies to predefined variant options, user-set channel numbers display properly across provider selections, and filtered-out providers no longer leak into dropdown menus.
As always, I really appreciate the feedback, enthusiasm, and passion around PrismCast. Almost every feature added since 1.0.0 has come from thoughtful, respectful discussion with this community.
My only ask is simple: please be kind, not demanding. PrismCast started as a project for my own needs, and I share it because I enjoy this community and wanted to give something back. Respectful feedback is always welcome; entitlement is not.
Thank you to everyone who's shared encouragement or joy in using PrismCast—it genuinely keeps this project fun to work on.
One more note for everyone's benefit: please don't repost the same questions in this thread. Many of them have already been asked and answered, and the forum's topic-only search works well. Keeping discussions focused helps everyone. Please treat the thread and each other with the same consideration you'd expect in return.
To reiterate from prior release notes:
If you've created user-defined channels that are now covered by predefined options, I recommend deleting those overrides and using the defaults. Predefined channels
are what I test and maintain; overrides are entirely optional, but they do create long-term configuration debt for you as PrismCast evolves.
