No, it's not in the doc.
It surely is, that's where I quoted it from-
https://ffmpeg.org/ffmpeg-all.html#Advanced-options and about 300 lines down
(or search for "-bsf"). It's around line 1760 of doc/ffmpeg.texi in the
source tree. (You could also look at
https://ffmpeg.org/ffmpeg-bitstream-filters.html)
Those are documentation for ffmpeg, pretty much the reference set unless you
read the source code.
And the 'doc' are programmer documentations, not user documentation.
Where did you get -that- idea? (User doc has been a thing for at least 50
years, I still have some of those books, and probably a lot longer.)
BTW, the text "underflow" only appears maybe 20 times in the copy of the
source I have handy (I'm not going to update just for this).
Possibly the most relevant ones are-
libavformat/mpegenc.c: "buffer underflow st=%d bufi=%d
size=%d\n",
libavcodec/ratecontrol.c: av_log(s->avctx, AV_LOG_ERROR, "rc
buffer underflow\n");
but we don't know _because_we_don't_have_the_console_output_.
z!
