Look for the CPU load in the performance tab. Check this article for steps to correct this.To catch this on the client side, you can check certain elements in the testRTC results: ![]() That said, there are several reasons for lip sync issues and A/V drifts to occur in WebRTC, which can be caught with testRTC: For the most part, A/V drift will occur not because the servers are “ruining” lip sync but rather because the resources on the client side can’t handle the load, so they throttle the incoming media and aren’t able to time the video with the voice. This was a lip sync character animation project for class I think this is pretty okay but since I had to use my own voice I took the audio out for this. Your application may process the media on the server side, changing it from the source and interrupting with lip syncing it programmaticallyĭue to the reasons above, we aren’t directly handling lip synchronization issues at testRTC. ![]() Network conditions affect incoming media, changing its resolution, frame rate, etc. Look, sometimes you have to acknowledge when a lip-sync is a total Moment.testRTC has no knowledge or understanding what the incoming media is and what source media this needs to be correlated with.This is because audio and video are “faked” separately, so if one is opened prior to the other they won’t be synchronized and even if they were, the browser may not view them as starting at the exact same point time This causes an inherent lip sync issues with our own source media in some scenarios. The browsers themselves don’t match audio and video in the source properly with fake media. ![]() This is quite challenging with a generic platform like testRTC, especially when our control over what gets received is quite minimal: The problem with lip sync testing is that it requires knowing the source media and being able to record, correlate and match it on the destination side. Today we are releasing LipSync, a web experience that lets you lip sync to music live in the web browser. We are asked from time to time if our platform can assist in catching lip sync issues, which are also known as A/V drift or other similar names. Kameron lip synced 5 times on season 10, besting the competition with relative ease.
