Unpredictable delay before first CC message is displayed

API and Webhooks
1

I read the page: https://support.zoom.us/hc/en-us/articles/115002212983-Integrating-a-third-party-closed-captioning-service

Description
Zoom replies to my initial Closed Caption POST with a timestamp and no error code, but the message is not displayed in the user interface, nor does it give the “Closed captioning available message” . Only after an unpredictable delay of between 15 seconds and several minutes does the user interface respond to subsequent CC messages. After that messages are displayed without delay.

Error
Initial Closed Captioning messages sent through the API are not responded to in the user interface. Only after an unpredictable delay after the first will a subsequent messages be recognized in the user interface

Which Endpoint/s?
wmcc.zoom.us/closedcaption

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

  1. Send Closed Caption http message as per the support article, with ‘&seq=Counter&lang=en-US’
  2. The POST response is timestamp & no error codes. NOTHING happens in ZOOM user interface
  3. Send more Closed Caption http message as per the support article, with '&seq=Counter+n&lang=en-US
  4. The POST response is timestamp & no error codes. NOTHING happens in ZOOM user interface
  5. Wait several seconds to several minutes
  6. Send another Closed Caption http message as per the support article, with '&seq=Counter+n&lang=en-US
  7. The POST response is timestamp & no error codes. Zoom user interface finally announces CC is available, and CC messages can be read (not including the first messages).

I’d appreciate guidance or a workaround.

Hey @roy.ballantine,

Since this is not actually apart of the Zoom API and marketplace, please direct this question to support.zoom.us, they will be able to better assist. :slight_smile:

Thanks,

Regretfully not. I have emailed support.zoom.us, but they have not responded yet. Perhaps you could email them too.

Good luck

Roy
