zoompan filter variables 'in' and 'on' start at 2, 1 instead of at 0

[Jim DeLaHunt]

Summary of the bug: The video filter zoompan creates variables in and on for use in expressions. They are described as the "input frame count" and "output frame count" respectively. When zoompan filters the first frame, in is 2, and on is 1. These are non-intuitive values. I expect them both to be 0 for the first frame.

How to reproduce: Use zoompan filter, with expressions which examine the in and on values for each frame.

Two invocations demonstrate this. Full invocations below and -report logs below.

Expected behaviour

I expect in and on to have the value 0 when the filter operates on the first input frame and generates the first output frame. This is consistent with how the n variable behaves with many other video filters, e.g. crop, drawtext, etc.

When the filter operates on subsequent output frames for a given input frame, I expect in to remain at the same value, and on to increment by 1 for each output frame.

When the filter operates on the next input frame, I expect both in and on to increment by 1 relative to their values for the final output frame of the previous input frame. on should not reset to zero; the zoompan:duration variable already has this behaviour.

I expect the documentation for zoompan's in and on variables to be clearer and more consistent with the documentation for the n variable in other video filters, e.g. crop. For example:

in: The number of the input frame, starting from 0. It keeps the same value as the filter generates successive output frames for the same input frame.
on: The number of the output frame, starting from 0. It increments as the filter generates successive output frames for a given input frame, and increments again when the filter moves to first output frame for the next input frame.

[Jim DeLaHunt]

This behaviour was discussed on ffmpeg-user list thread ​Zoompan filter, frame counts seem to start from 2 and 1, not 0 -- expected behaviour?

Gyan Doshi's comment: "This change occurred when zoompan switched to activate in
2ce43274e39295e3965c51dcfaf802628a5929f9". I think that means ​this diff of libavformat/vf_zoompan.c.

[Gyan]

There is a bug of sorts with the value of in but the assignment logic of in and on is correct. They are meant to be cardinal values, measuring the amount fed in and fed. The n in crop, drawtext amd some other filters are ordinal values and represent the index which starts from 0.

[Jim DeLaHunt]

I tried to read through the code and simulate it in my head. If you accept my claim that in and on should start at 0 instead of 1 and 2, then I think the fix is in libavfilter/vf_zoompan.c, function activate(), lines 252:317.

The variables appear to be set in lines 277:278:

        s->var_values[VAR_IN]    = inlink->frame_count_out + 1;
        s->var_values[VAR_ON]    = outlink->frame_count_in + 1;

Removing the +1 from each expression would correct on to the ordinal value, and get in closer.

I think other discrepancy with the in value comes from this lines 277:278 being called after having called ff_inlink_consume_frame(inlink, &s->in)) in line 269.

    if (!s->in && (ret = ff_inlink_consume_frame(inlink, &s->in)) > 0) {
        ...[omitted]...
    }

ff_inlink_consume_frame() calls consume_update(), which increments link->frame_count_out. This is essentially:

    out++;
    in = out;

when maybe the original intention was:

    in = out++;

[Jim DeLaHunt]

Replying to Gyan:

... the assignment logic of in and on is correct. They are meant to be cardinal values, measuring the amount fed in and fed. The n in crop, drawtext amd some other filters are ordinal values and represent the index which starts from 0.

Oh, ffmpeg project....

Where is this cardinal vs ordinal intention recorded? The documentation is vague. There's no comment in the code saying that these are to be cardinal. I don't see a compelling reason for this filter to be inconsistent, in using cardinal numbers where other filters use ordinal numbers.

That said, the ordinal vs cardinal distinction could be viewed as an interface commitment with users of the filter. Changing starting numbers from 1 to 0 could disrupt some users of the filter. I don't suppose we have much of a way of knowing how bad the disruption would be.

And, cardinal = ordinal + 1, so anyone who wants an ordinal value can easily calculate it from a cardinal value.

Certainly, it would be very desirable to state the ordinal or cardinal choice clearly in both the code and the docs.

[Gyan]

IMHO, the docs do give the correct indication

For n in crop:

The number of the input frame, starting from 0.

number of the (singular noun) == serial number -> ordinal.

For in:

Input frame count.

count == measure -> cardinal.

---

Why the filter needs to expose count and not index is better left for the dev to answer.

[Jim DeLaHunt]

I hope to hear what the dev has to say about exposing count and not index.

I see your point about the subtle connotations of "count" vs "number of the".

But my stance towards how this filter (and this project in general) communicates to humans reading its docs and its code is that it needs a lot more "how can we make this even better" than "how can we justify that what is there is arguably adequate".

[Elon Musk]

Fixed in 983288538669f19df3b6f1e19b00488a5d2ec8bd.

[Jim DeLaHunt]

Tested this fix with the same invocation as before, but this time on commit b737317a8813e671c00b8ac7023c47e48ffeb1c8 of the master branch.

./ffmpeg -report -v +repeat -to 0.3 -i fate-suite/h264/interlaced_crop.mp4 -an \
-vf "crop=x=print(1234000+n)*0,zoompan=d=1:s=qhd:zoom=print(2718000+in)*0+print(3142000+on)*0+1" \
-f mp4 -y /dev/null
...[omitted here for brevity] ...
1234000.000000
1234000.000000
2718000.000000
3142000.000000
...[omitted here for brevity] ...

Note that the values for n, in, and on, shown in the last three digits before the decimal point, are equal now, and start from 0. They differed before.

It would be good to also change the documentation to clarify these values. The documentation now reads:

in

Input frame count.

on

Output frame count.

I believe the documentation should change to read, using the language cited by Gyan from crop:

in

Input frame number (index), starting from 0.

on

Output frame number (index), starting from 0.

I may submit this patch, if no-one beats me to it.

The full report from the above invocation is:

Tested with ffmpeg 4.1 as released by the FFmpeg project. The bug is fixed in version 4.1.

ffmpeg -report -v +repeat -to 0.3 -i fate-suite/h264/interlaced_crop.mp4 -an -vf "crop=x=print(1234000+n)*0,zoompan=d=1:s=qhd:zoom=print(2718000+in)*0+print(3142000+on)*0+1" -f mp4 -y /dev/null

...[omitted here for brevity] ...

Note that the values for n, in, and on, shown in the last three digits before the decimal point, are equal now, and start from 0. They differed before

The full ffmpeg report output (with the fate-suite path prefix deleted because it had my filesystem info in it) is:
