Description

I'm using a post process script after a recording has finished which converts the .ts file into a .mkv via ffmpeg. It creates the .mkv file in parallel and when the conversion has finished, it calls the TVH API to inform TVH about the filechange:

_TVH_IP="10.0.6.2" 
_TVH_PORT="9981" 
_API_ENDPOINT="/api/dvr/entry/filemoved" 
_BIN_CURL="/usr/bin/curl" 

....

success=0
repeat=0
while [ "$repeat" -lt 10 ]; do
  if ${_BIN_CURL} -s "http://${_TVH_IP}:${_TVH_PORT}${_API_ENDPOINT}" \
    --data-urlencode "src=${TSVIDEO}"                           \
    --data-urlencode "dst=${MKVIDEO}" > /dev/null; then
    echo -e "$(date): Notification successful!" 
    echo -e "$(date): Notification successful!" >> $logfile
    success=1
    break
  else
    echo -e "$(date): Notification attempt failed ..." 
    echo -e "$(date): Notification attempt failed ..." >> $logfile
    sleep 30
  fi
  repeat=$((repeat+1))
done

....

Unfortunately in 80% of all cases TVH crashes right when the API is called the first time. When the TVH server has restarted, the notification usually works right after the server came back. But the next recording which calls the API leads again to the crash.

If there is any workaround or alternative method to inform TVH about the file change, I'd be happy to use this until the issue is fixed. This has a huge impact to my installation as we're mostly doing recordings and watch them later.
