bug: only record one side audio

[wangduanduan]

many records only record one side audio, only a few record both side

This looks more like a issue with the data mirroring. Can you verify using Wireshark that both side audio is reaching till oreka?

There is no special treatment of packets which would cause one sided recording.

[wangduanduan]

I open the recording file use the audacity, i find that two channels have same wave cursor, so may be one channel has wrong data mirroring.

i try use PcapFilter config to fix the problem, and it worked!!

here is my network

hostA ---RTP---HostB---RTP---hostC

I install orkaudio on the hostB, mybe orkaudio capture both hostA--RTP--HostB and hostB---RTP---hostC, so i set PcapFilter to host hostA_IP and udp

[kingster]

Glad that it worked :)

Yes, it all depends on what how the mirroring has been done. Since in your case the recorder is running on the same box as HostB which is passthrough, it might have threated both sides as 2 legs as different sides and lead to that, applying the pcap filter ensured that it only treated recordings from the traffic of hostA.

PS: I am closing this issue as resolved. Please do create a new issue if you face a any other problem.
