Live streams are playing OK.
However for a recording I am trying to play, the player gives this message in chrome: media decoder error (mp4a.40.2, avc1.64001E)
However, it can play any part of the video - but just for about five seconds. So the video seems all right.
Playing OK in iPad.
Firefox says “Unable to play audio codec: mp4a.40.2 Video codec: avc1.64001E”
Now in the same directory with the same code I tried another video, HG\_Class\_\_20180303.mp4 and in chrome it simply gets stream unavailable
However this was certainly recorded within wowza using H.264 and AAC.
However, on my current non-wowza player, it plays properly in flash.
These are serious issues with playback of VOD.
Any suggestions?

I guess it was the wrong encoding - I am getting files recorded recently playing properly now.
To play older MP4’s, I included “useFlash”:true, when I created my playerElement.
They have a better chance of playing properly in the flash player. That way if flash is not available, the player will also attempt to play them in the non-flash player.
