I need a lightweight, command-line workflow that generates reliable fingerprints from existing media with FFmpeg we already have implemented for some players working well. we need a manner to put it also in live streaming channels without encoding/transcoding a plugin with ffmpeg wich will stay always on standby mode so when we trigger our python code it should visible in stream injected. do not come with options for transcoding if i want it transcoded or encoded i know how to do this by my self already. tellme what you gonna use to do this.
