[FFmpeg-user] How to silently ignore inexistent inputs

[Yevgen Voronetskyy]

I’ve tried to use this approach with ffprobe to check the aliveness of streams.
Unfortunately, the streams unpublishing are quite often, so the time gap is rather big and often I still getting the same error…

Anyway, thank you for your response :)
