 Check [https://forum.videohelp.com/threads/393903 this] (the last part,
 "The original file (what I threw at !YouTube)").

 I believe similar behavior shall occur with different audio/video input.
 (actually... happened to notice this when trying to spam some random stuff
 on !YouTube)
 Extra things I've tested:
 \\1. Changing the container format to AVI and using the very audio track
 in WAV format.
 No help.

 \\2. Slightly increasing `-vframes` to make the video duration longer than
 the audio's.
 No help.

 \\3. Inversing the command's input argument positions, like this:
 ffmpeg -i "1.flac" -loop 1 -i "Entrepreneurship.png" -c:a copy -c:v
 libx264 -r 15 -vframes 3548 -preset placebo -qp 0 -x264-params
 "level=5.1:keyint=infinite:no-deblock=1" -pix_fmt yuv420p -sws_flags
 spline+accurate_rnd+full_chroma_int -color_range 1 -colorspace 5
 -color_primaries 5 -color_trc 6 "1.mkv"
 No help.
