FreeSWITCH 1.8.2 on latest Debian Stretch, compiled stock from source, deps installed via FS repo.
I have FreeSWITCH managed by systemd to start at boot, which works well. However, I'm hitting a weird issue where, after initial system boot, if I try to play a video file into a conference via mod_av, the video is frozen on the first frame (audio is fine). If I restart FreeSWITCH, then the video file plays fine.
Any thoughts on what might be causing this? My only guess: on boot systemd starts FreeSWITCH before some other service or setup that is needed to play video files via mod_av, and restarting FreeSWITCH fixes the issue because said service is now running.
