Website media provenance

These files are copied from the frozen Astribot sample bundle (the original source path is retained in the table for provenance) for the ActiveArena project website. The MP4 streams are losslessly remuxed with the moov index at the beginning (faststart); encoded video samples are unchanged. Posters are WebP snapshots from frame 0. *-observer-hero.webp is a higher-quality still from the observer stream for the landing hero.

Camera and evaluation semantics

  • head is the robot head camera and is the policy observation view in these examples.
  • observer and world are external visualization cameras. They are included for explanation and qualitative comparison only; they are not policy inputs and must not be used as evaluation observations.
  • demo corresponds to info_gathering_demo_ppt_samples__info_gathering_demo_ppt_external_views; ood corresponds to the randomized sample directory (info_gathering_randomized_ppt_samples__info_gathering_randomized_ppt_external_views).

Validation

  • All six MP4s are H.264 High Profile, yuv420p, 30 FPS, with no audio stream.
  • Every output was decoded successfully with PyAV, and every decoded frame matched its source pixel-for-pixel.
  • Container order is ftyp → moov → free → mdat, so the first frame can load before the full file is downloaded.
  • docs/media.json contains source/output SHA-256 values and the full machine-readable metadata.
