Old description:

> The output file test.txt is 0 bytes.
>
> The same test with 'signalstats' in place of 'mestimate' produces the
> output in the documentation.

>
> ffmpeg -y -i test.mp4 -filter_complex
> "mestimate,metadata=print:key=lavfi.mestimate:file=test.txt" test_out.mp4

New description:

 The mestimate values for each frame should be written to test.txt.
 The output file test.txt contains pts information, no mestimate values.

 The same test with 'signalstats' in place of 'mestimate' produces the
 output in the documentation.

 ffmpeg -f lavfi -i testsrc=duration=10:size=1280x720:rate=30 test.mp4

 ffmpeg -y -i test.mp4 -filter_complex
 "mestimate,metadata=printfile=test.txt" test_out.mp4

 ffmpeg -y -i test.mp4 -filter_complex
 "mestimate,metadata=print:key=lavfi.mestimate:file=test.txt" test_out.mp4
