Here is the log from the server
setting mix layout...
0|index | joinChannel...
0|index | appliteDir /Meeting/record/src/sdk/bin/
0|index | pRecording->m_agorasdk->createChannel return result:1

Nothing happen.

When I try to use run sdkdemo.js
pRecording->m_agorasdk->createChannel return result:1

In the output folder, I only see recording_sys.log, recording_0.log, agorasdkk_cache.dat and so on no video files.
Is there anything that I missed.
