This seems to have broken Edl commercial skipping for me in Krypton HEAD. When it goes to do an Edl skip (VideoPlayer.cpp Line ~2421) video and audio both hang. Doing a manual seek forward or backward allows playback to continue.

I confirmed it was this commit since this is a one line change, commenting it out fixes the problem for me.

I tried two different videos and several different Edl commercials in each one and they all had this problem, I don't think it is specific to my recordings or my EDLs.

I see the issue which is a design flaw of EDL skipping. Instead of looking the the actual playing time it looks at the other end of the demuxer queue. As a result a cumbersome delayed flushing process was implemented that blocks the player thread for up to 8 seconds.
I rarely touched edl so far but now its time to do some rework.
