Hi, I believe that I've stumbled across a slow memory leak in the QSV encoder, or possibly the underlying library I'm not really sure. I've been able to see a slow leak (~50MB/hr in the worst case) in ffmpeg processes performing an QSV encode where an identical configuration running a CUDA encode

Dear All I do live streaming and I need to pick up the audio from a microphone. I test latency like this: ffplay -f pulse -i "alsa_input.usb-Remo_Tech_Co.__Ltd._OBSBOT_Tiny-02.analog-mono" ffplay -f alsa -i default After running one of the commands I can hear my own voice in my headphones.
