I have gigabit speed, and I don't download anything concurrently that may interrupt it. Its just this one video (for me obviously) from multiple sources that is the weird part! Running ffprobe appears beyond my expertise... The zipped file is 150 mb which appears to large for the server. I'll just break it up into chunks for Whisper and merge when done.., but thanks for the offer. Maybe it's a VLC thing? Hmmmm.I second @soloporhoy666 note, it probably is caused because of a audio decoding error. What does ffprobe say? If you share your audio file I can try to run a test on it.
