#10976 new defect
ffmpeg/avfilter: multiple outputs with one having rarer output causes memory ballooning

Description (last modified by )
Summary of the bug:
Flagging this as both ffmpeg CLI as well as avfilter, as I am not sure which is the part that is the larger cause of this (ffmpeg CLI's API usage or the internals of avfilter's synchronization logic itself).
After d119ae2fd82a494d9430ff4d4fc262961a68c598 , ffmpeg CLI started memory ballooning with an input as well as a filter chain where there is one output which provides less often than the other ones. Before this the test case would have a maximum resident set size of about 60 megabytes, while now the same test case shows buffering of 100 frames in the outputs which should be able to output more often and has a maximum resident set size of around 4 gigabytes.
Thankfully, to reproduce this no specific input or output encoders or muxers are required.
How to reproduce:
% /usr/bin/time -v \
ffmpeg -v verbose \
-f lavfi -i "testsrc2=r=24:d=10:s=1280x720" \
-filter_complex "[0:v]split=4[v0][v1][v2][thumb_in];[v0]scale=3840:2160[out0];[v1]scale=1920:1080[out1];[v2]scale=1280:720[out2];[thumb_in]fps=1/60:round=up:start_time=0[thumb_out]" \
-map '[out0]' -f null pipe: \
-map '[out1]' -f null pipe: \
-map '[out2]' -f null pipe: \
-map '[thumb_out]' -f null pipe:

Note:
The underlying issue might be much older, and the ffmpeg CLI threading commit might have just made things more consistent. This is due to the fact that in case of there not being any actual inputs, but just the complex filter chain, this has been happening at least with release/2.0 if not earlier (the test case started segfaulting at release/1.2, at which point I decided to start writing up this ticket).
Example from the same version which has a maximum resident set size of ~60MiB when an input is involved:
