main.py

The playback_speed parameter passed to the
main()
function is not being used when calling run_arcade_replay(). Instead, the playback speed is hardcoded to 1.0, making it impossible to adjust the replay speed.

Location
File:
main.py

Line: 58

Current Behavior
The
main()
function accepts a playback_speed parameter (line 7), which is set to 1 on line 82. However, when run_arcade_replay() is called on line 58, the playback speed is hardcoded to 1.0:

run_arcade_replay(
frames=race_telemetry['frames'],
track_statuses=race_telemetry['track_statuses'],
example_lap=example_lap,
drivers=drivers,
playback_speed=1.0, # ❌ Hardcoded value
driver_colors=race_telemetry['driver_colors'],
title=f"{session.event['EventName']} - {'Sprint' if session_type == 'S' else 'Race'}",
total_laps=race_telemetry['total_laps'],
circuit_rotation=circuit_rotation,
chart=chart,
)

Expected Behavior
The function should use the playback_speed parameter that was passed to
main():
run_arcade_replay(
frames=race_telemetry['frames'],
track_statuses=race_telemetry['track_statuses'],
example_lap=example_lap,
drivers=drivers,
playback_speed=playback_speed, # ✅ Use the parameter
driver_colors=race_telemetry['driver_colors'],
title=f"{session.event['EventName']} - {'Sprint' if session_type == 'S' else 'Race'}",
total_laps=race_telemetry['total_laps'],
circuit_rotation=circuit_rotation,
chart=chart,
)

Impact
Users cannot adjust the playback speed of race replays
The playback_speed parameter exists but has no effect
Any future command-line arguments or configurations for playback speed would be ignored
Suggested Fix
Replace line 58:playback_speed=1.0,
with:playback_speed=playback_speed,

Steps to Reproduce
1.Modify the playback_speed variable on line 82 to a different value (e.g., 2.0)
2.Run the script
3.Observe that the replay still runs at 1.0x speed
