Livestream MP4 and JPG do not work

I import multiple RTSP streams (via Live pull settings -> new RTSP URL) and embed them as a live stream using videojs player on web pages and HTTPS. This works without any problems.

Now I have enabled MP4 and JPG thumbnails in the global settings. Applications are currently not configured, so the global settings should be used.

The link of the outgoing stream looks like this:
https://<domain>/<app>/<stream>/playlist.m3u8

Now I tried to open the thumbnails, but:
https://<domain>/<app>/<stream>/thumbnail.mp4
https://<domain>/<app>/<stream>/thumbnail.jpg
https://<domain>/<app>/<stream>/dvr_thumbnail.jpg
all just show a 404 Not found.

Are these links correct?
Do the JPG thumbnails require a transcoder license?

Thanks!
Max

Hello Max.
Please make sure the input streams were restarted after modifying 'Global' or 'Applications' transmuxing settings.
MP4 thumbnails are generated without Transcoder license.
JPEG thumbnails generation require Transcoder license.

Hi Aleksandr,
thanks for the input, restarting the stream did the trick, I read over the last sentence in the instructions... Lever 8...
Sorry and thank you!
