ICPC kanpur regional mock issue: OBS virtual camera on zoom
By aditya_sheth, history, 3 years ago, In English

I am not able to share the virtual camera of OBS on zoom. How to fix this issue? I tried leaving and re-entering zoom, but that's not working.

UPD : I am using Macbook Air M1,2020

On a MacBook Air 2017, my CPU utilisation is ~80%. I have honestly never heard my fan run until today.

OBS made my system lag that much that it would take whole time to just code up a Div2 A problem.

Unable to share webcam through OBS (it shows blank) and system is lagging a lot.

Proctoring platform needs to be changed removed.

I removed OBS but, the camera's gone :feelssadman:

    To spice things up, the rule book says: "A contestant is not be allowed to participate/rejoin the contest if he disappears/disconnect from the Zoom room for more than 5 Minutes."

LoL, I waited for 1 hr+ and no breakout room was assigned. And just a few hours before mock they have sent some shitty rule-book with so many requirements. Poor management.

    Guess that makes sense, so that people can't send code to each other

      In rules, it has been given that the team members can share code among themselves only using zoom chat.

I think those who faced even a single issue during the mock round should mail to icpc@gla.ac.in with their concerns. Maybe doing so will bring the attention of authorities to the potential issues.

Issues (if people want to mail, they can send these issues, plus add their own if any):

  1. System slows down by a lot
  2. Code cannot be seen clearly in the shared video due to very poor quality (some issue in Zoom/OBS)
  3. Sharing face + screen for 3.5+ hours is going to consume a lot of internet
  4. System hangs after we click on stop recording after recording for 2+ hours
  5. Low word limit in zoom chat, cannot share long codes
  6. Some proctors were AFK
  7. Some proctors ended the meet preemptively
  8. Some proctors didn't assign breakout rooms on time
  9. Proctors' mics were on, and all proctors were seated near each other and hence a lot of noise and disturbance was coming from their mics. Hence cannot focus on the problems
  10. Cannot see our own submissions on CodeMarshal Platform

    "Some proctors didn't assign breakout rooms on time" I think this issue is much bigger than it looks. Proctors in our room were completely unprepared about what to do, even as close to 1730hrs and after it. We weren't able to discuss the problems because other team participants were also present in the same meeting. Not only that, even after breakout rooms was assigned, other team members were still present in our room. To the point where our proctor was telling us, 15mins into the contest, that our team is in the wrong meeting and we should leave and rejoin the correct meet.

    Of course, in the mock contest with trivial problems it doesn't matter. But, in real contest, all I want is peace of mind at least five minutes before the contest starts. Don't care what your rules are, just let me read the problems and attempt the contest peacefully!

In our team case, Zoom gave me a notification to update Zoom to latest version, which for some reason automatically closed the ICPC Zoom meeting. I didn't even click on Yes, nevertheless I tried joining the Zoom meet again and waited 20+ minutes but nobody let me in. Very dissatisfied with ICPC Kanpur

if someone is still facing the issue, try quiting the zoom and turning on the obs virtual camera, and ater turning the obs virtual camera, start the zoom.

This fixed the issue for me.
