Comment (by q3cpma):

 This is actually exactly like the link said.
 ffmpeg -i 20s.mkv -map 0:v:0 -c:v ffv1 ffv1.mkv
 ffmpeg -i 20s.mkv -i ffv1.mkv -map 0:a -map 0:s -map 1:v -c copy out.mkv

 ffmpeg -i 20s.mkv -c:a copy -c:s copy -c:v ffv1 out2.mkv
 out.mkv fails while out2.mkv works; when the operation is fundamentally
 the same.
