FFMPEG MJPEG encoder produces extra RST marker at the end of the stream.
Steps to reproduce:
{{{
% ffmpeg -f lavfi -i color=c=black:s=1920x1080 -thread_type slice
-frames:v 1 test.jpg
fmpeg version N-95941-g637742b45d Copyright (c) 2000-2019 the FFmpeg
developers
...
% xxd -s -4 test.jpg
000082c4: ffd3 ffd9 ....
}}}
0xFFD3 is a RST3 marker. If I understand it correctly, according to
[https://www.w3.org/Graphics/JPEG/itu-t81.pdf ITU-T T.81] (figure E.3),
there should not be a trailing restart marker after that there is no data.
