Hi, I’m using wowza streaming engine 4.6.0.

I encoded a set of video files to mp4 format **with the same setting**. Most of them are streamed well but **few files are not streamed**. I encoded the files with ffmpeg and changed codec several times, I cannot stream the flies.

Here is the error message in the wowzastreamingengine\_error.log
