    ffmpeg and multi threading

    I have 4 big wmv files i want to convert to avi.

    I use ffmpeg to convert them.

    I notice the ffmpeg uses over 90% of CPU (all cores) when it is running in background.

    I then create two threads each running an instance of ffmpeg. The CPU usage now reaches 100%.

    Should I leave the max threads at two then as its using 100% CPU.

    I once tried 5 threads (5 instances of ffmpeg running at same time) but the PC started bleeping and slowing down. I take it this is due to overloading the CPU?

    Is your CPU multi-core ?

    C++ programmers will dismiss you as a cretinous simpleton for your inability to keep track of pointers chained 6 levels deep and Java programmers will pillory you for buying into the evils of Microsoft. Meanwhile C# programmers will get paid just a little bit more than you for writing exactly the same code and VB6 programmers will continue to whitter on about "footprints". - FunkyDexter
