Found a bug that crashes NR #32

Closed WhiteLionATX closed 1 year ago

WhiteLionATX commented 1 year ago

I am not sure why this happens. What could be: I paused one of the video streams at about 14:30 accidently. Then I continued to play the paused stream and wanted to see how much is buffered. I expected that at the end of the buffered stream it will auto switch to live view or so. To I guess that this might not happened instead it crashed.

Sorry. This is posted on the wrong repo. Anything related to the use of node-red-mp4frag should be discussed on the node-red forum to better communicate the problem and how to duplicate it and fix it. This repo is just a dependency for node-red-mp4frag. Also, the error sounds like you ran out of memory. More can be discussed in the forum if you make a post and tag me there.
