[FFmpeg-user] ffplay on current build does not play mkv file but on old build does.

Hi Moritz, Not sure what I supposed to see but I didn't see anything other
than the command window.  Also the command window did not seem to respond
to 'q'.  I had to ctrl + c three times to force it to stop.

Here's the console output and command for September 26 build

Here's the command and output for 24th build. As you stated in your reply
this was before they changed to sdl2 so the error that occurs makes sense.
