Description

Documentation at https://guacamole.apache.org/doc/gug/installing-guacamole.html specifies that libavcodec is needed only when guacenc is required. Nevertheless when --with-libavcodec=no is specified in configure script it is causing that protocols RDP, SSH, Telnet are not supported.

Prerequisite: All required packages for RDP, SSH, Telnet, VNC are installed:

Steps to reproduce:

tar -xzf guacamole-server-1.4.0.tar.gz
cd guacamole-server-1.4.0
./configure --with-libavformat=no

Output:

------------------------------------------------
guacamole-server version 1.4.0
------------------------------------------------

   Library status:

     freerdp2 ............ no
     pango ............... no
     libavcodec .......... disabled
     libavformat.......... no
     libavutil ........... no
     libssh2 ............. yes
     libssl .............. yes
     libswscale .......... no
     libtelnet ........... yes
     libVNCServer ........ yes
     libvorbis ........... yes
     libpulse ............ no
     libwebsockets ....... no
     libwebp ............. yes
     wsock32 ............. no

   Protocol support:

      Kubernetes .... no
      RDP ........... no
      SSH ........... no
      Telnet ........ no
      VNC ........... yes

   Services / tools:

      guacd ...... yes
      guacenc .... no
      guaclog .... yes

   FreeRDP plugins: no
   Init scripts: no
   Systemd units: no

Type "make" to compile guacamole-server.

Without the explicit specification of --with-libavformat=no:

tar -xzf guacamole-server-1.4.0.tar.gz
cd guacamole-server-1.4.0
./configure

Output:

------------------------------------------------
guacamole-server version 1.4.0

     libswscale .......... no
     libtelnet ........... yes
