Compiled FFmpeg not accepting -c:v and -c:a

Question

I compiled FFmpeg with libsrt, with the online compile guide. https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu & how to compile ffmpeg with enabling libsrt

It seems to compile correctly.

ffmpeg version N-96575-g843c24a Copyright (c) 2000-2020 the FFmpeg developers
built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1)
configuration: --prefix=/home/ubuntu/ffmpeg_build --pkg-config-flags=--static --extra-cflags=-I/home/ubuntu/ffmpeg_build/include --extra-ldflags=-L/home/ubuntu/ffmpeg_build/lib --extra-libs='-lpthread -lm' --bindir=/home/ubuntu/bin --enable-gpl --enable-libaom --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-libsrt --enable-nonfree

libavcodec     58. 67.100 / 58. 67.100
libavformat    58. 37.100 / 58. 37.100

libswresample   3.  6.100 /  3.  6.100
libpostproc    55.  6.100 / 55.  6.100

But when running this command to convert a incoming SRT stream to HLS, it doesn't know the -c:a command. When switching the order, it runs that it doesn't know about the -c:v command.

ffmpeg -re -i srt://0.0.0.0:25000?pkt_size=1316&mode=listener -c:a copy -c:v copy -strict -f hls -hls_time 4 -hls_playlist_type event stream.m3u8

~$ ffmpeg -re -i srt://0.0.0.0:25000?pkt_size=1316&mode=listener -c:a copy -c:v copy -strict -f hls -hls_time 4 -hls_playlist_type event stream.m3u8

I have searched the issue, but I could not find anything similar. Does someone know what I have missed in the setup?

Everything is manually compiled through the guide, this was the final command I run to compile FFmpeg:

cd ~/ffmpeg_sources && \
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \
tar xjvf ffmpeg-snapshot.tar.bz2 && \
cd ffmpeg && \
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
  --prefix="$HOME/ffmpeg_build" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  --extra-libs="-lpthread -lm" \
  --bindir="$HOME/bin" \
  --enable-gpl \

make install && \
hash -r

Nothing to do with ffmpeg. The shell treats 1316 as the end of the command and & as the background operator.

Enclose the full URL in quotes to avoid this.

"srt://0.0.0.0:25000?pkt_size=1316&mode=listener"
