This issue is separate from the Shield High bitrate issue because I have the test image installed and it fixed the problem when I play the files in VLC. The video will play for a few seconds then get distorted/flashes of green screen. This is only when using the emby player, if I select external player and set it to VLC they play fine. Here is the server log and ffmpeg log.
I did not see anything weird but I did look around for long, figured I would leave it to the experts! It is for Planet Eath 2.
