The singlejpeg muxer was removed in that commit, on April 10th 2021:
Whose text is:
"It was added in 51ac1f616f due to ticket #4218, in order to show a single
image via ffserver. With ffserver long gone, it serves no purpose."
singlejpeg is useful for generating jpeg on stdout. For example here, extracting a cover embedded in an mp3:
ffmpeg -i blargh.mp3 -map 0:1 -f singlejpeg - > /dev/null
Command above is for illustrating purpose and not super useful in itself,
but a program might want to generate a jpeg this way in memory (thus to stdout), for example to http stream it (without writing it to a file first).
I have such program that make use of singlejpeg this way.
Please consider re-adding singlejpeg.
