Fix out-of-bounds accesses when rendering ghost players, which use the client ID `-2`. This was causing the hook collision line of ghost players to be affected by real players, which is not correct, as ghosts do not interact with other characters.
Closes#8239.
Add optional filename argument to `start_video` command, to start recording to a video file with a specific filename, instead of always using the current timestamp.
Add log messages to `start_video` and `stop_video` commands to indicate success and errors.
Make the `CClient::StartVideo` function non-`static` and reduce duplicate code in the `Con_StartVideo` function.
Determine the video filename outside of the `CVideo` constructor, same as for demos.
Fix game times and prediction not being updated when only exactly two snapshots have been received, due to the conditions `m_aReceivedSnapshots[...] >= 3`. These specific condition are not necessary and replaced with simpler checks whether the current snapshot is set. Some duplicate nested conditions are also removed.
Pump the network first in `CClient::Update` before updating anything else, to ensure that snapshots are received from the network client before the game times and prediction are being updated based on the current snapshots.
Fix current and previous game tick always being `0` on the first call of `IGameClient::OnNewSnapshot` when two snapshot have been received. Now, the game ticks are properly initialized from the two initial snapshots.
Fix old inputs sometimes being used in prediction after changing map because inputs with tick `-1` were not being ignored.
Ensure all snapshots and game times are properly cleared when entering the game.
`GetConsoleMode` can fail with `ERROR_INVALID_HANDLE` when redirecting output to `nul`, which is considered a character file but cannot be used as a console.
The purpose of this condition is to only update the freeze time every 50 ticks so the freeze bar keeps being refilled after one second when standing in freeze, but it incorrectly prevented freeze from being applied during the first 50 ticks after the map has been loaded. Now, freeze is also applied if not currently frozen, so the behavior directly after changing the map is identical to subsequent respawns.
Clear current server info when playing demos to ensure that the score kind (points, time) is detected correctly. Previously, when playing a demo with points score kind and `cl_demo_assume_race 0`, the score was not shown as points when the last server that the client connected to had a race gametype.
Move the implementation for `cl_demo_assume_race` together with the rest of the demo server info initialization in the `CClient::DemoPlayer_Play` function.
