Why does this happen?

[joe33067]

I've run across a few movies that when streaming, will play audio, but not video. I thought it was a transcoding issue, so I manually transcoded one of the movies, but it's still not showing me video.

Any ideas what's not working ?

Hi Joe,
can you please post the ffmpeg information of the file by right-clicking on the file in Mezzmo and select Get FFmpeg Information then copy and paste it into a post. Can you also remind us of what device you are streaming to and also the device profile you are using?

[joe33067]

Next time it happens, for certain. This time around, a power cycle of the media player (NextD) and of the media server rectified the issue.

Here's a title that's not playing (and a power cycle didn't allow the title to play. I'm transcoding it now to see if that will fix it)

This file has hevc video so if your player does not support hevc then it will not show the video.

Ah Ok. Thx for explaining Peter.
