Audio delay/lag #8

Open sedony23 opened 5 years ago

sedony23 commented 5 years ago

I have the problem of significant audio delay. It probably is a general Dafang hacks issue, but I wanted to ask here, because I use it mainly with homebridge/homekit. Are there any suggestions for the optimal setup of video/audio parameters? Here is my current setup:

Video: h265, 1280x720, VBR, Bitrate 1024kbps, 25fps Audio: MP3, 16000 in and out, NS filter moderate, high pass filter on, AEC filter on

Homebridge is running on a raspberry pi 3 b+

I also get the delay in VLC though...

Hey @sedony23 , I have 7 connected Xiaomi Cameras to the plugin and i am using a mac mini for homebridge instead of Raspberry Pi (RPi isnt powerful enough for streaming high quality video). And i can reproduce your issue with 2 of my cameras with HomeKit as well as VLC. It seems to be an issue from RTSP stream or the audio driver of Xiaomi Camera.

I am currently looking into audio protocol on the camera for Two-way audio, will look over audio lag as well. I am looking into approach inspired by :

Great. Thanks for the info! Looking forward to two-way audio and a solution for the lagging audio issue!
