ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i a.mp4 -c:v hevc_vaapi -q:v 28 -f null - -benchmark
returns:
... bench: utime=0.156s stime=0.195s rtime=3.003s bench: maxrss=358944kB
NOTE: The maxrss serves to indicate the maximum RAM used during the ffmpeg execution.
The utime, stime, rtime indicate accordingly:
- user time;
- system time;
- real time.
The following parts of the command force a null file and tells ffmpeg to benchmark.
- -f null - -benchmark
