  "message": "tp: android.display.video data source, importer, table and stats (#6143)\n\nAdds trace_processor support for the android.display.video data source,\nwhich captures device display frames as a hardware video elementary\nstream.\n\nWire format (protos/perfetto/trace/android/video_frame.proto):\n* VideoFrame (TracePacket.video_frame): a codec_config-only frame per\nstream (carrying display_name + RFC 6381 codec_string), then one\nVideoFrame per on-screen change with a single access unit (au_data).\nSelf-identifying via a per-session display_id.\n* VideoFrameError (TracePacket.video_frame_error): per-stream failure\nwith a Reason enum (size cap hit, codec error, display gone, no encoder,\ndisplay not found, encoder setup failed, virtual display failed).\nConfig: DataSourceConfig.display_video_config.\n\nImporter (src/trace_processor/plugins/video_frame_importer/):\n* Parses video_frame into the __intrinsic_video_frames table. The\nencoded payload is stored zero-copy as a TraceBlobView, surfaced via the\n__INTRINSIC_VIDEO_FRAME_AU_DATA(id) scalar function (same pattern\nHPROF/ETM use for blob payloads).\n* Maps each VideoFrameError reason to its own kIndexed entry in the\nglobal stats table, keyed by display_id.\n* Enforces a parse-time 256 MB per-stream cap as a backstop against\ntraces recorded without a producer cap: over-cap frames are dropped and\nandroid_video_size_cap_hit is reported once.\n\nThe table is intrinsic (not a stdlib module) since only the VideoFrames\nUI consumes it.\n\nTests: diff tests (single/multi display, au_data blob equivalence, all\nVideoFrameError reasons) and a unit test for the parse-time cap.",
