'generate thumbnail from stream jaffree Java
I am trying to generate a thumbnail from a video stream using jaffree thought they didn't mention in their docs anything about generating thumbnail. I tried to figure it out on my own but it doesn't seem to work.
code for thumbnail generating :
public PipedOutputStream generatethumbnail(){
PipedOutputStream image = new PipedOutputStream();
FFmpeg.atPath()
.addInput(PipeInput.pumpFrom(stream).setPosition(1L, TimeUnit.SECONDS))
.addOutput(PipeOutput.pumpTo(image).setFormat("image2"))
.execute();
return image;
}
}
the stack trace when i run a test :

Since the output info is shown, I assume that the thumbnail is generated but somehow interrupted, isn't it?
Note: I need ffmpeg output to be a stream uploaded to an object storage server.
ffmpeg used : ffmpeg 5.0-static tried this version ffmpeg-3.4.2-static which worked before on nodejs app with fluent-ffmpeg
