@abhishekmv.dev , It is likely you are using a newer version of the SDK, and some of the interfaces have not been implemented. For now, could you try with 5.16.10? I’ll update the sample with the latest SDK in a while ---

You need to implement below abstract classes to custom classes - MeetingParticipantsCtrlEventListener - MeetingRecordingCtrlEventListener Then create instances of those. ---

@abhishekmv.dev for recording token, you will need to use an OAuth app to get a meeting recording token. Below is the specific token which you need to get using the REST API > **[Zoom Meeting API](https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/meetingLocalRecordingJoinToken)** > > API Reference for /docs/api/rest/reference/zoom-api/methods ---

@chunsiong.zoom @freelancer.nak Thank you . I’m able to get the access token using server-to-server OAuth app and used access token to get recording token. I need to use this recording token in config.txt file in meetingsdk-linux-raw-recording-sample to access raw audio and raw video in a headless docker environment. I have doubt in the content of config.txt file: meeting\_number: “1234567890” token: “xxxxxxxx.yyyyyyyyyyyyyyyyyy.zzzzzzzzzzzzzzzzz” meeting\_password: “123456” recording\_token: “” GetVideoRawData: “true” GetAudioRawData: “true” SendVideoRawData: “false” SendAudioRawData: “false” With respect to above content ,I have two questions: 1. Is meeting\_number same as meeting ID of Zoom ? 2. Is the token field value above is the access token that I got using S2S OAuth app ? Please clarify. ---

@abhishekmv.dev I’ll be closing this thread as it is going off topic and and chaining multiple topics. I would strongly encourage you to look at some docker tutorial. The error which you have encountered is due to running 2 separate commands at same time instead of running them one by one. If you still have issues, please open a new thread and tag me [Next page](https://devforum.zoom.us/t/error-after-executing-make-in-the-demo-build-folder/102772.md?page=2)
