Demo of Raw Audio and Raw Video access over Zoom Meeting SDK, Custom UI

This is a sample code of how you can access raw audio and raw video using Custom UI It is based on Meeting SDK for Windows, Version 5.15.12

Here are some assumptions

• The user who use this editing codebase chooses the customized interface (customUI)
• The user who is accessing raw audio and raw video has either host, co-host, or recording permission
• The SDK has successfully joined the meeting, subsequently has an "in meeting" status, and "start recording status" before raw audio and raw video can be access
• The code snippets' starting point happens when user clicks on the "local record" button in Custom UI

There are a total of 6 files which have been altered and created.

I will not provided the full SDK here, you will need to download Meeting SDK for Windows Version 5.15.12 from marketplace.zoom.us

Add the code listed below.

• Added: RawAudioDelegate.cpp
• Added: RawAudioDelegate.h
• Added: RawVideoDelegate.cpp
• Added: RawVideoDelegate.h

Alter the code listed below. Do not replace

• Alter: CustomizedUIRecordMgr.h
• Alter: CustomizedUIRecordMgr.cpp

To help you understand the code, I've used the comments in these source and header files //added for raw data access in CustomizedUIRecordMgr.h and CustomizedUIRecordMgr.cpp

The output file will be audio.pcm and output.yuv found in the root directory zoom-sdk-windows-5.xx.x.xxxx\x64\demo\sdk_demo_v2\

Convert audio.pcm to a playable wav file by using ffmpeg -f s16le -ar 32k -ac 1 -i audio.pcm audio.wav. You will need to install ffmpeg if you have not already done so.

Convert 360.yuv, 720.yuv and 1080.yuv to a playable mp4 file by using either

• ffmpeg -f rawvideo -vcodec rawvideo -s 640x360 -r 25 -pix_fmt yuv420p -i 360.yuv -c:v libx264 360.mp4
• ffmpeg -f rawvideo -vcodec rawvideo -s 1280x720 -r 25 -pix_fmt yuv420p -i 720.yuv -c:v libx264 720.mp4
• ffmpeg -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p -i 1080.yuv -c:v libx264 1080.mp4 You will need to install ffmpeg if you have not already done so.

If in RawVideoDelegate.cpp, on RawDataFrameReceive the name is output.yuv name a command that can be used to convert is the same as

• ffmpeg -s 640x480 -i .\output.yuv -ss 00:00:00 -c:v libx264 -s:v 640x480 -t 00:08:20 output.mp4
