zoompan progress stops after 2 sec when it is overlayed

[HERVE M GERARD]

The problem occurs when we try to overlay a zoompan filter with a 'zoom in' progress effect.
The 'zoom in' progress stops at 2 sec whatever the value of 'd'.

Here is the command line:

/usr/local/ffmpeg_static/ffmpeg -loglevel 9  -y  \
-f lavfi -r 25 -i color=black \
-loop 1 -r 25 -i /home/storage/pictures/3537/7403/2408/element_567_1417213924_animal1_900x726.png \
-filter_complex " \

The input of your zoompan filter has a frame every 1/25 second, but the zoompan filter will duplicate each one 250, making it 10 seconds long. Thus:

in: t=0.00 → out: t∈[0.00, 10.00[
in: t=0.04 → out: t∈[0.04, 10.04[
in: t=0.08 → out: t∈[0.08, 10.08[
...

The output segments overlap instead of being monotonic. You need to either set the input frame rate to make them monotonic or completely override the output timestamps.

[HERVE M GERARD]

No solutions seem working despite your comment.
Could-you please give an example of zoompan with overlay that the zoom-in effect takes any longer?

[HERVE M GERARD]

If this is not a bug, please could you give an example of working solution. rgd

[Elon Musk]

Workaround is to not use overlay and zoompan in same filtergraph.
Process video with zoompan save it and later use overlay...

[HERVE M GERARD]

Thanks for this confirmation. I hoped it was possible.

[Ryan Williams]

Problem can be worked around using the fifo filter but be warned it consumes lots of memory.

[Elon Musk]

Should be fixed in f42eae96b22d2f9a823bc616b2424164524eed96.
