fission 0.1.2

0.1.2 — steadier playback for large 4K files, and a tidier Settings

This update makes playback of very large 4K files dependable on TVs with a small Java heap, fixes two control and lifecycle defects, and removes an obsolete Settings screen. It is still early software — behaviour changes between builds, and a build can break.

Install

1. Install Downloader by AFTVnews from the Google Play store on your Android TV.
2. Open Downloader and enter the permanent fission code 7197071; it opens https://infusionplayer.stream/download/.
3. Choose 0.1.2, download infusion-tv-0.1.2-102.apk, and let Downloader install it.

The full procedure, including the adb path, is in the releases repository README. If you already run 0.1.1, install this build over it — your profiles, add-ons, watch history and Home layout are kept.

What's new

• Settings → About now shows the version you are running. The About title reads fission v0.1.2 on this build, and the version is read from the installed app itself rather than written into the interface, so it cannot drift from what you actually have.
• Settings is shorter. The Diagnostics screen and its "Open diagnostics" action have been removed from the TV and phone settings. The app still keeps its own internal diagnostics for its playback health reporting; there is simply no longer a screen that exports them.
• A restored app comes back where you left it. After Android has to recreate a backgrounded app, the screen you were on is restored instead of leaving the branded start-up screen in the way.

Fixes

• Large 4K files no longer run the app out of Java heap. The player used to plan its buffering against a fixed assumption about how much memory the rest of the app was using. On a very large 4K container that assumption was wrong, the process ran out of Java heap and playback died. The player now measures the memory it actually has free before deciding how much of the file to hold, and only lowers the amount of buffering when it has to. Ordinary HD and 4K playback behaves as before.
• More buffering headroom on Android TV. The TV app now also asks the platform for a larger Java heap, so the measured buffering plan has more room to work with on TVs that offer it.
• Restart is available again with local-only tracking. With no external tracker connected, Restart used to appear greyed out on Details even when the title had real local progress. It now behaves like the main play action: same title, same source list, starting from the beginning.
• The start-up screen no longer stays up after Android restores the app. If the system ended the app in the background and you came back to it on a screen that is not Home, the branded start-up screen could stay in front of the restored screen forever. It now clears as soon as the restored screen is ready, and the remote works again immediately.

Known issues

• Sideload only. There is no store listing; new builds appear on the Releases page.
• Android TV only. There is no mobile installer; do not install the TV build on a phone.
• If you are not offered this update inside the app, download it from the Releases page instead.
• Focus, playback and presentation are qualified on the NVIDIA Shield and a Sony BRAVIA; other Android TV devices are untested.
• Installing over a test build signed with a different certificate is refused by Android (INSTALL_FAILED_UPDATE_INCOMPATIBLE); uninstall the old build first.
• Playback depends on the source you configure — your Jellyfin server or the add-ons you install. This build does not make every stream or provider play without interruption, and a provider that changes or withholds a stream can still fail to play.
• This is an alpha: behaviour can change between builds and some surfaces are still being polished.

Download both infusion-tv-0.1.2-102.apk and SHA256SUMS from the Assets list. sha256sum infusion-tv-0.1.2-102.apk must print the first value, and sha256sum -c SHA256SUMS must print OK. apksigner verify --print-certs infusion-tv-0.1.2-102.apk must print the second. The two values identify different things — the file's bytes, and who signed it — and neither proves the other.
