            Bug ID: 255687
           Summary: www/chromium crashes on Microsoft Teams
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: chromium at FreeBSD.org
          Reporter: zarychtam at plan-b.pwste.edu.pl

             Flags: maintainer-feedback?(chromium at FreeBSD.org)

I have started to use www/chromium with Teams recently. It works fine until
someone shares the screen with me then the tab almost immediately crashes. It
can be also triggered by changing the video layout to "Large Galery" or
"Together" mode during the conference. The crash message looks like below:
#
# Fatal error in:
../../third_party/webrtc/modules/video_coding/codecs/h264/h264_decoder_impl.cc,
line 80
# last system error: 35
# Check failed: context->lowres == 0 (223629728 vs. 0)

The overall user experience of using Microsoft Teams with native www/chromium
is pleasant, there is no problems with voice conferencing and making
presentations, sharing screen, etc. though during the normal operation I
observe a lot of harmless warnings:

# [6783:111352:0507/211953.124614:ERROR:network.cc(436)] Too many network
