Kodi stuck/freeze when closing external player with STOP (keyboard x, json like yatse do...)

When kodi starts an external player and STOP is pressed inside kodi (X on keyboard, stop button in yatse which sends a json stop, ...) kodi stuck/freezes. This was reproduced on two windows 10 x64 clients with latest nightly.

This issue does not happen when the external player is closed by itself (ALT-F4...).

To reproduce:

  • create a playercorefactory.xml with the contents from the quote at the bottom
  • create c:\temp\test.bat with the contents from the quote at the bottom
  • install latest nightly windows x64
  • run kodi and start a movie with 4K in its filename to launch the external player (bat)
  • DONT close the batch file
  • Switch to kodi back with ALT-TAB
  • Press X on the keyboard
  • External Player gets closed
  • Kodi freezes

The last message in the log is (regardless if debug is on or not):

14:14:45.181 T:6040  NOTICE: CExternalPlayer::ExecuteAppW32: WAIT_OBJECT_0
14:14:45.181 T:6040  NOTICE: CExternalPlayer::Process: Stop
14:14:45.315 T:6040  NOTICE: CExternalPlayer::Process: Showing Kodi window

So it seems the issue happens right after those outputs in ExternalPlayer.cpp in function Proccess. Maybe @ line:


playercorefactory.xml which launches c:\temp\test.bat:

        <player name="MPC-HC" type="ExternalPlayer" audio="false" video="true">
    <rules action="prepend">
        <rule filename=".*4K.*" player="MPC-HC"/>        

contents of test.bat:

@echo off
echo Playing "%1"

I have debugged it to he call of:

SetWindowPos(m_hWnd, windowAfter, 0, 0, 0, 0, SWP_NOMOVE|SWP_NOSIZE|SWP_SHOWWINDOW);

in function CWinSystemWin32::Show(). This wikndows API is the last function which gets called until kodi freezes! Have checked the m_hWnd, its correct and the same hwnd as spyxx.exe is showing. windowAfter is 0, and this is the value for HWND_TOP, which is ok.

Any hints?
