fix(linux): bundle full GStreamer codec suite for YouTube playback#434
Conversation
AppImage only bundled gst-plugins-base and gst-plugins-good, missing H.264/AAC (gst-libav), x264 (plugins-ugly), AV1 (plugins-bad), and GL video sink (gst-gl). YouTube's MSE player checks codec support via MediaSource.isTypeSupported() — WebKitGTK delegates to GStreamer and reports no compatible decoders, showing "can't play this video". Add plugins-bad, plugins-ugly, gst-libav, and gst-gl to CI install so bundleMediaFramework includes them in the AppImage.

…plugins The AppImage bundles GStreamer from CI (Ubuntu 24.04, GStreamer 1.24). Previously, host plugin directories (/usr/lib/gstreamer-1.0/) were appended as fallback. This caused ABI version mismatches — host plugins compiled against a different GStreamer version fail with undefined symbol errors (gst_util_floor_log2, mpg123_open_handle64, etc.), leaving WebKit without usable codecs for YouTube playback. Since PR #434 installs the full GStreamer codec suite on CI, the AppImage is fully self-contained. Remove the host fallback and block host plugin scanning to prevent ABI conflicts across distro GStreamer versions.
