Generate Thumbnail images of Live Streams using the Wowza Streaming Engine Java API encountered a problem,When I pushed the RTSP live stream to select the program Instance, I customized the Instance name, but when I got the screenshot, I could not get the screenshot, so I could get the screenshot with Default Instance
Wowza Streaming Engine’s Transcoder can output thumbnails in JPG format. More information can be found in the articles below. Is your screenshot JPG?
It sounds like you followed our JAVA API doc on how to do this, but did you happen to see our doc on this here? You can also try this module.
The only way we can truly determine why it’s not working for you would be through a support ticket so we can have full access to your files/logs and test your configuration.
