Module `Fehu_visualize.Video`Source

Video recording wrappers for environments and vectorized environments.

Sourcetype when_to_record =

| Every_n_episodes of int
| Steps of int -> bool
(*
Recording schedule.
- Every_n_episodes n: record every n-th episode (1-indexed)
- Steps predicate: record steps where predicate global_step is true
*)

val record_video : 
  when_to_record:when_to_record ->
  path:string ->
  ?overlay:Overlay.t ->
  ('obs, 'act, Fehu.Render.t) Fehu.Env.t ->
  ('obs, 'act, Fehu.Render.t) Fehu.Env.t

Record an environment to per-episode or per-step video files under path.

overlay customises rendered frames before they are written.

  layout:[ `Single_each | `NxM_grid of int * int ] ->
  when_to_record:when_to_record ->

  ?overlay:Overlay.t ->
  ('obs, 'act, Fehu.Render.t) Fehu.Vector_env.t ->
  ('obs, 'act, Fehu.Render.t) Fehu.Vector_env.t

Record a vectorized environment.

`Single_each: apply record_video to each inner environment with a dedicated sub-directory
`NxM_grid rows_cols: compose frames into a grid before writing.

path is treated as a directory and created if it does not exist.
