Works for me here.

Can you share what makes it special, though, so I can try and reproduce the
issue? The issue should be triggered by the order and timing of the frames,
not their contents.
(This is one of the cases where Stefano's text demuxer would come handy.)

I have always said that using -vframes with several streams is not
supported. Its exact result depends on undocumented and unguaranteed
properties of the scheduling, both inside libavfilter and ffmpeg.c, or even
caused by input or users. We could enhance that, the change would take place
in ffmpeg.c:need_output().
I am glad you say this change improves the accuracy. A better scheduling is
one of the purposes. But even if it did worsen it in some cases, I think it
would be acceptable, as long as it is only a bit.
