Use the earliest input with the same status.
If that fails, print a warning and use the earliest source.

of EOF.

actually forward it.

avfilter: take_samples: do not directly return frame when samples are skipped
...
Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.
This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).
Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
./ffmpeg -filter_complex "aevalsrc=0:n=1166,firequalizer=fixed=on" -f null null

Instead of just updating statistics and leaving the work to the
call site, have it actually do the work.
Also: skip the samples by updating the frame data pointers
instead of moving the samples. More efficient and avoid writing
into shared frames.
