[FFmpeg-user] SCTE-35 passthrough in transcoding process

That’s what we were seeing from our searching as well. I do know that there are vendors that output cable channels after decryption with a cable card, with SCTE-35 that are using FFMPEG in the backend code. Silicon Dust with the now discontinued PRIME units for an example. Does anyone know how this is being facilitated?
