MacOS Transcode Unknown Source

We have a customised zoom windows application (using the Windows C# SDK) that generates encoded “.meetingrec” recording files. We are trying to transcode these recordings from a MacOS commandline script - using the “” executable. We want to automate this process, however we have been receiving a Dialogue Pop-Up saying that the encoded file is from an “unknown source” and such we need to click “convert anyway”. Is there anyway to avoid this Pop-Up so we can automate this process.

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Make a recording on a Windows machine
  2. Import the recording to a Mac
  3. Rename the recording files to “double_click_to_convert_0#.zoom”
  4. From the command line, call “”'s executable, passing one of the encoded files as an argument
  5. See the popup

Hey @harry130899,

Thanks for using the dev forum!

Does this also happen when you use the Zoom client to produce the recording instead of the SDK?



Thanks for the reply.
This doesn’t happen when the client is used. However, we are using the SDK system to automatically join meetings and begin recording - so using the client to manually create the recordings is not a feasible solution.

It is also worth noting that if we use “zTscoder.exe” from the SDK on a windows machine, it doesn’t happen, whereas, it does happen when using “” on a MacOS machine.


Hey @harry130899,

Hmm that is interesting. I would contact Apple Developer Support about this one. This is unfortunately out of scope for our SDK support.
