high cpu during no progress

Description

Summary of the bug:

I've a situation where I'm running ffmpeg. However, it is making no progress since the HTTP request is stalled. Even though it is making no progress and getting new data FFMPEG is still using 50% cpu. What could be causing this?

Does the HTTP have some kind of live polling loop which is taking cpu?

How to reproduce:

% ffmpeg -hide_banner -nostdin -i http://storage:8000/file/LytbBlT5~8pCwR.gif -c copy -f null -

  • Component changed from ffmpeg to undetermined

You forgot to remove -hide_banner which must not be used for valid bug reports (unless an issue with the option itself) and backtrace when the high cpu usage happens.
(Your command line does not allow reproducing the issue.)
