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.mp4ffmpeg -f rawvideo -vcodec rawvideo -s 1280x720 -r 25 -pix_fmt yuv420p -i 720.yuv -c:v libx264 720.mp4ffmpeg -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p -i 1080.yuv -c:v libx264 1080.mp4You 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
