For some reason i dont understand mplay is not launching. My gpu drivers are updated, and i ve tried very simple scenes like a cube rotating, tried to do a flipbook but it crashes every time. in the task manager it says houdini is not responding and the only thing thart is different lately is that this error message appears when i launch houdini.Maybe this has something to do with it?I havent upgraded to a newer version of Houdini, i m still running 17 version and flipbooks worked before.
But it does work when i save directly to disk!
Any ideas?

I've seen this one in the past which was partially fixed in 17.0.425. Could you post your environment settings you are using to replicate the problem ?

I wasn't able to reproduce the problem with 17.0.416. A fix was added to 17.0.425, can you try with 17.0.459 or 17.0.506?
