Spectator View: Broken Audio #64

Open jieseattle opened 7 years ago

jieseattle commented 7 years ago

With default settings, audio generated from apps are broken in recorded files, even with sample code in 240. We integrated Spectator view with a few of our own solutions, same results. Haven't got time to go through what could be the issue.

Can you describe the audio behavior you are observing?

I could hear some popping in my audio, so I increased the audio bitrate in my latest pull request and it seems to have improved the audio a bit.

jieseattle commented 7 years ago

Yup, it is like popping. We also tried to increase the bitrate and that doesn't really fix the problem. I need to analyze the files using Audition to see what exactly is causing the popping. Not quite sure if it is an issue of AAC compression or not. Will get back to you later,.

we identified this as a performance issue - when recording video in 1080p, this didn't happen on our rig (AMD 1800X). It only happens when dealing with 4K content.

~Seems resolved. Please reopen if not.~

Leaving open, in case this is investigated and determined to be an SV performance issue.
