I’m trying to capture x11 screen recording and pulse audio and mux them into one rtp output stream but I’m having issues when it comes to the actual muxing part. If I record only audio or only video then the resulting output stream plays with little issue but once I mux them together then the stream gets jittery and the audio drops/stutters randomly. Here’s my FFMPEG commands (launched from JavaScript)

Here is the resulting cli logs:

>From what I’ve seen this has to do with the separate timestamps for each stream not lining up correctly and causing playback error I’m just not sure how to fix it. Forward Error Correction has had no effect. Any ideas on how I can ensure the tracks are synced?
