Comment (by alqemyst):

 I can reproduce it with libx264 also. Reason why I was testing here with
 nvidia and vaapi is because leak is faster that way.

 It seems with http input leak is slower and I don't have enough data, also
 udp with cirrcular buffer. When I append cirrcular buffer I can very
 quickly see memory increasing. Of course when ffmpeg is compiled with
 --disable-pthreads fifo_sze is omitted but I kept same command.

 I will continue investigation and let you know if I find something more
 useful. Same ffmpeg and same commands, at least QSV, VAAPI and libx264
 work on Debian without leaks.
