How to accurately measure latency or delay from transcoder input to output
Is there a procedure on how to accurately test latency/delay on wowza transcoder addon? Maybe something that I can enable in the logs or API to make wowza log the time from the frame being decoded to the final transcoded output?
I am not aware of a technial tool that will fulfill your request. That is not to say one does not exist.
For a live workflow, with access to the broadcast venue, I would use a visual and an audio cue and a stopwatch to make rough measurements. Understandably, when dealing with remote clients, this is not practical, however, a simple approach like this should do the trick.
I am very interested if anyone else has more information on this.
