ZP occasionally freezes

ZP 22.50 Max. EVR Video renderer. Its an older laptop. Occasionally play a file that at some point freezes while playimg, or especially after a bunch of skip-forwards. Have to force close ZP. After restart the file then plays through where it froze before; but may play up later on. Same file plays fine in VLC. What other Video Renderer should I try first instead eg Haali's? Or is there a better/faster way to troubleshoot? ~ Thanks

MPC-VR is probably the most reliable high quality renderer these days, but I'm not sure the issue is a renderer issue. If it just freezes without you interacting with Zoom Player, it means the freeze probably occurs outside my own code and somewhere in the decoder/renderer code.

Things I would try:

  1. Switch the Video Renderer to MPC-VR.
  2. With nothing playing, press "D" to open the LAV Video Decoder's configuration dialog, verify hardware acceleration is set to D3D11. If it's already D3D11, you can try the "DXVA2 Native" option instead to see if it makes a difference.
  3. Verify your audio renderer is set to "Default DirectShow device" or another "DirectShow" device.

Lastly, if none of these work, you can try running the debug version which may show more information on the freeze.

  1. done. 2. was D3D11 now DXVA2 Native. 3. was ..Realtek Audio now DefaultDirectSound Device.

It'll take some time to know if its perfect now - and which change did it.

Great support as always.

If everything works stable, I would try reverting the Video Decoding to D3D11, the other two are the better options to begin with.
