Proto: - New VideoFrame message (field 129 on TracePacket) with frame_number, jpg_image, track_name, and track_id fields. - track_name/track_id enable multi-stream support (e.g. multiple cameras). Trace Processor: - VideoFrameModule: parses TracePacket.video_frame, stores JPEG bytes in a dedicated TraceBlobView vector. Metadata (ts, frame_number, track_name, track_id) goes to __intrinsic_video_frames table. - video_frame_image(id) SQL function: returns raw JPEG BLOB. - android.video_frames stdlib module. - Video frames contribute to trace_start()/trace_end() bounds. UI (dev.perfetto.VideoFrames plugin): - Instant events rendered via SliceTrack on the timeline. - Per-stream tracks grouped under a collapsible "Video Frames" node, each named by track_name. - Details panel with frame metadata, image preview, and playback controls (play/pause/prev/next, configurable fps 1-240). - Area selection tab per stream for independent playback. - Playback in single-select mode advances the track selection. - FPS setting shared across all panels in the session.
