Transcoder (ffmpeg) immediately dies

Everything appears to be working well for me, up until the remote transcoder.

For context:

This is Dockerized and contains Node 8, RClone, UnicornTranscoder, and S6 for service start and config. UnicornTranscoder installs fine, starts up, and receives events from the load balancer.

The issue appears to be that immediately after starting the transcoder it does, with no indication as to why. I had a thought that it might have been path names not being escaped, so I moved the “Plex Transcoder” to “PlexTranscoder”, set my env appropriately, and retested with no avail. I can run the commands within the container as the specified user and receive output:

In my last attempt, I have been rewritting to regex certain parameters which appear to be unescaped and causing the failure

.replace('{INTERNAL_TRANSCODER}', "http://127.0.0.1:" + config.port + '/') .replace('{INTERNAL_RESOURCES}', PlexDirectories.getPlexResources()) .replace(/[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}\/seglist/, this.uuid + '/seglist') .replace(/[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}\/manifest/, this.uuid + '/manifest') .replace(/(\/RCloneMedia\/[a-zA-z0-9\/].*\.[a-zA-Z]{3})/g, '"$1"') .replace(/(expr:gte\(.*\))/g, '"$1"') .replace(/(-filter_complex\s[\S]*)/g, '"$1"')

Is it possible that during the argument, they are becoming unescaped and causing this failure? If I escape the required parameters (and append for an output), it will begin transcoding a file.

Let me know if you need more explanation! Hoping to come up with a solution!

Okay, I’ll add in that and rerun and test and see where that leaves me. I’ll additional rebuild and check the container to make sure there’s nothing on that end as well.

WIll be back with logs shortly! Thanks!
