Ok, it looks strange, so i write here.
Game Team Fortress 2, SourceMod v1.9.0.6237, extension v1.1.1 (manually builded from sourcecode with CLang).

All works good, but SourceTV_GetRecordingTick() always return -1.
I have code:

void Recorder_Stop() {
  Recorder_Validate(); // this is stock just checks, recording in progress or not. if not - throws an error.

  int iRecordedTicks = SourceTV_GetRecordingTick();
  SourceTV_StopRecording();
  g_bRecording = false;
  g_iEndTime = GetTime();

  char szDemoPath[PLATFORM_MAX_PATH];
  int iPos = FormatEx(szDemoPath, sizeof(szDemoPath), "%s/%s", g_szBaseDemoPath, g_szDemoName);

  strcopy(szDemoPath[iPos], sizeof(szDemoPath)-iPos, ".json");
  JSONObject hMetaInfo = new JSONObject();
  hMetaInfo.SetInt("start_time",      g_iStartTime);
  hMetaInfo.SetInt("end_time",        g_iEndTime);
  hMetaInfo.SetInt("recorded_ticks",  iRecordedTicks);
  hMetaInfo.SetString("unique_id",    g_szDemoName);
  hMetaInfo.SetString("play_map",     g_szMapName);
  // ... more code for writing JSON too ...
  // ... saving JSON ...
}

Note: i write recorded_ticks with value from SourceTV_GetRecordingTicks(). Native called before stopping record.
All looks good, but in JSON:

{
    "start_time": 1565718510,
    "end_time": 1565722914,
    "recorded_ticks": -1,
    // more additional fields...
}

What i do wrong?
