'''Summary of the bug:'''
Piping from yuv4mpegpipe to another external encoder seems to be broken,
at least on Ubuntu and Arch. Static and shared builds seem to encounter
the same issue. The problem started rising with builds from October 29th
to October 30th. Problem is still present using the git-master.
My snapshot from October 20th works fine.
The issue arises no matter the container(Matroska or MP4), the source
codec(AVC/HEVC/VP9/MPEG2), and the encoder(rav1e/x264/aomenc/libvpx, all
from their git-masters).
'''How to reproduce:'''
1. Compile ffmpeg normally on Ubuntu 20.04/20.10.
(./configure --enable-gpl --enable-version3 --enable-nonfree)
2. Run the command below
{{{
% ffmpeg -v 9 -loglevel 99 -i input.mkv -r 30 -s 1920x1080 -f yuv4mpegpipe
-pix_fmt yuv420p - | aomenc --cpu-used=6 -o output.ivf -
}}}
3. I get this error, and the piping stops.
{{{
% av_interleaved_write_frame(): Broken pipe
Error writing trailer of pipe:: Broken pipe
