HLTV CS2 POV Rendered Dataset

Rendered Counter-Strike 2 POV training clips derived from blanchon/cs2_dataset_demo. Each row is one one-minute-or-shorter player POV chunk. The default config is previews, a small inline overlay+audio video view for browsing. The heavy chunks config contains embedded full-resolution video, audio, inputs, and world-state streams.

The raw HLTV .dem files stay in the source dataset. This repo stores only the rendered training dataset.

Configs

• previews (default): one low-resolution preview_video row per chunk with the input overlay baked in, plus cheap filters like player_side, primary_weapon, and survived_chunk.
• matches: one row per rendered (match_id, map_name) with team/event/date metadata.
• rounds: one row per rendered (match_id, map_name, round) with tick boundaries.
• chunks: full training rows with video, audio, inputs, worlds, and typed metadata.

Filesystem Layout

data/
  match_<match_id>/map_<map_name>/player_<player>/
    chunks-preview-<machine>-<uuid>.parquet
    chunks-full-<machine>-<uuid>.parquet
index/
  manifest-<machine>-<uuid>.parquet
  rounds-<machine>-<uuid>.parquet
state/
  processed/<input_metadata_stem>/<match_id>.json
  failed/...
  skipped/...

Every machine writes a unique <machine>-<uuid> shard, so parallel uploads do not touch the same files. state/processed is written only after the shard upload succeeds.

Stream With datasets

from datasets import load_dataset

repo = "blanchon/cs2_dataset_render"

# Cheap default browsing view.
previews = load_dataset(repo, split="train", streaming=True)
for row in previews.take(3):
    print(row["match_id"], row["round"], row["player"], row["preview_video"])

# Full training rows. Use columns/filters to avoid pulling unused bytes.
chunks = load_dataset(
    repo,
    "chunks",
    split="train",
    streaming=True,
    columns=["video", "audio", "inputs", "worlds", "match_id", "round", "player"],
    filters=[("player", "==", 0)],
)

Row Semantics

• player is the stable canonical 0-9 player index for a match.
• spec_slot is the transient CS2 spectator slot used only to record the POV.
• Recording starts at the playable round start (freeze_end_tick) and stops at the player's death tick, or at round end for survivors.
• The production worker validates exactly 10 canonical players per round, unique spec-slot resolution, no recording past death, and valid video/audio/ inputs/world sidecars before upload.
