-------------------------------------+-------------------------------------
Summary of the bug:
In some configurations, `-f ffmetadata` as an output option will prevent
the filter chain from being applied.
----
How to reproduce:
{{{
% ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -f ffmetadata -c
pcm_f32le basic_no_map.ffmeta
}}}
But, `-filter_complex` works:
{{{
ffmpeg -hide_banner -i test.wav -filter_complex
"astats=measure_perchannel=none:measure_overall=Entropy" -f ffmetadata -c
pcm_f32le complex_no_map.ffmeta
}}}
As does `-f lavfi -i amovie=`:
{{{
ffmpeg -hide_banner -f lavfi -i
"amovie=test.wav,astats=measure_perchannel=none:measure_overall=Entropy"
-f ffmetadata -c pcm_f32le lavfi_no_map.ffmeta
}}}
----
But, this triad is different:
`-filter` does not work:
{{{
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -f ffmetadata
basic_no_map_no_codec.ffmeta
}}}
And `-filter_complex` gives an error:
{{{
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -c pcm_f32le -f
ffmetadata basic_codec_ffmetadata_map_null.ffmeta -map 0 -f null -
[aost#0:0 @ 0000022a8a09aa40] Automatic encoder selection failed Default
encoder for format ffmetadata (codec none) is probably disabled. Please
choose an encoder manually.
}}}
But, `-f lavfi -i amovie=` works correctly:
{{{
ffmpeg -hide_banner -f lavfi -i
"amovie=test.wav,astats=measure_perchannel=none:measure_overall=Entropy"
-f ffmetadata lavfi_no_map_no_codec.ffmeta
}}}
----
The same thing happens with `aspectralstats` (stdout is empty):
{{{
ffmpeg -hide_banner -i test.wav -filter
"aspectralstats=measure=mean,ametadata=print:file=-" -f ffmetadata -c
pcm_f32le aspectralstats_basic_no_map.ffmeta
}}}
----
The same triad with `signalstats`:
`-filter` does not work:
{{{
ffmpeg -hide_banner -i test/testVideo11sec.mkv -filter
"signalstats,metadata=print:file=-" -f ffmetadata
signalstats_basic_no_map_no_codec.ffmeta
}}}
`-filter_complex` gives an error:
{{{
ffmpeg -hide_banner -i test/testVideo11sec.mkv -filter_complex
"signalstats,metadata=print:file=-" -f ffmetadata
signalstats_complex_no_map_no_codec.ffmeta
[vost#0:0 @ 000001c885cc8040] Automatic encoder selection failed Default
encoder for format ffmetadata (codec none) is probably disabled. Please
choose an encoder manually.
}}}
`-f lavfi -i movie=` works:
{{{
ffmpeg -hide_banner -f lavfi -i
"movie=test/testVideo11sec.mkv,signalstats,metadata=print:file=-" -f
ffmetadata signalstats_lavfi_no_map_no_codec.ffmeta
}}}
----
The contents of the FFmetadata file ''sometimes'' correlates with success
or failure.
Success: complex_no_map.ffmeta:
{{{
;FFMETADATA1
encoder=Lavf61.3.104
[STREAM]
encoder=Lavc61.7.100 pcm_f32le
[CHAPTER]
TIMEBASE=1/48000
START=132003
END=302400
title=bike\\shed
}}}
Failure: basic_no_map.ffmeta:
{{{
;FFMETADATA1
encoder=Lavf61.3.104
[CHAPTER]
TIMEBASE=1/48000
START=132003
END=302400
title=bike\\shed
}}}
----
Can also reproduce, at a minimum, with:
{{{
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -c pcm_f32le -f
ffmetadata basic_codec_ffmetadata_map_null.ffmeta -map 0 -f null -
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -c pcm_f32le -f
ffmetadata basic_codec_map_null.ffmeta -map 0 -f null -
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -map 0 -f
ffmetadata basic_map_no_codec.ffmeta
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -f ffmetadata
basic_map_null.ffmeta -map 0 -f null -
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -c pcm_f32le -f
ffmetadata basic_no_map_codec_first.ffmeta
ffmpeg -hide_banner -i test.wav -filter
"astats=measure_perchannel=none:measure_overall=Entropy" -f ffmetadata
basic_no_map_no_codec.ffmeta
}}}
