Hi,

I’m using FFmpeg for a project as a live encoder to send my video (sample.mp4 for example) to Wowza and then play the stream on VLC.

I’ve made it for AVC without any trouble, but for HEVC i have several problems…

Here’s my ffmpeg line :

```auto
ffmpeg -re -i myFile -c:v libx265 -preset fast -x265-params crf=23 -strict experimental -f mpegts udp://127.0.0.1:10000

```

On Wowza, i see input bytes in the "incoming streams” menu but I cant do any playback using the media players (black screen). Does Wowza have a player that could play HEVC ? Or maybe my ffmpeg command is false…

On VLC, i open my AVC network stream with :

rtmp://wowza server:1935/live/mystream.stream

No idea how to do this with HEVC. I try :

udp://wowzaserver:1935/live/mystream.stream

It doesnt work…

I dont want to use DivX or the transcoder Addon.

Thank you very much for your help!😉

Denis

This was dealt with in ticket #129658.

As Denis discovered, there currently appears to be an issue with DivX web player and HEVC streams as [reported here](https://forums.divx.com/divx/topics/-emergency-problems-with-10-3-update).
