Description
To record from webcam and microphone and overlay a resized logo, using complex_filter I achieve about 20fps (on a fast pc with less than 15% cpu load), using the same features but with -vf I get full realtime 30fps...
I know this is normal because the complex filter has more options and it's more flexible, but IMHO this should not happen...
Example:
Record live feed from webcam and microphone, overlay a logo and save to flv..
ffmpeg -f dshow -video_size qpal -rtbufsize 1G -copyts -framerate 30 -i video="BisonCam, NB Pro" -i "C:\Users\Zibri\Downloads\scdc.png" -filter_complex "[1]scale=80x60,[0]overlay=W-w-5:H-h-5" -f dshow -i audio="Microphone (Realtek High Definition Audio)" -codec:v libx264 -preset fast -b:v 500k -b:a 128k -minrate 500k -maxrate 500k -bufsize 1500k -f flv test7.flv

The fisrt command settles after a few minutes around 10-15 fps.
The second one stays steady at 30 fps (camera is 30fps).
Note the bitrate is also broken and showing wrong.
Another note: when playing with ffplay I get normal video in both cases... and ffplay says it's 30fps anso "test7" which as you saw goes down to 16 when recording..

Can you explain this behaviour and why the fps is so different while recording?

if you read my ticket, you will understand if it is an issue or not. In my opinion it is an issue (multiple ones).
comment:3 by , 8 years ago
One command uses preset slow and another one uses preset fast.
I failed to reproduce using just overlay and movie filter.

The command that uses the slow preset has the highest fps during recording. The fast preset command is slow.
Some complications: a live source, the minor changes made to change from complex filtergraph to a 'simple' one. What happens if you use a video file as the input and change the '-vf' in the second command back to '-lavfi' or '-filter_complex'?
In my experience, filter_complex uses bilinear filter for scaling by default instead of bicubic, and sometimes has varied output between runs instead of always the same for vf, but haven't noticed it to be slower.
I did once find that having an extra filter (showinfo) seemed to result in better performance, but I think this might actually have been due to keeping CPU or GPU at a high frequency.
