Comment 2 for bug 1443864

If VLC is actively trying to open a new file, it can use all available CPUs, or at the very least two of them. After that, if it has an anomalously high CPU usage, it will only use 100% of one CPU. However, it seems that after a while this will stop even if no other videos are played; and in fact, playing an existing video does not actually cause the high CPU usage to stop; only after enough time has passed will it stop.
