            Bug ID: 236434
           Summary: WebKit crashes on camera release
           Product: WebKit
           Version: WebKit Local Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

The WebKit crashes sometimes, when I try to release the camera within a WebRTC Session. I'm not sure, if it is a gstreamer or a WebKit Problem.

During my Debugging I got this log-Messages from gstreamer periodically every 100ms:

0:00:17.919461061    53 0x7f9d08008120 WARN           v4l2allocator gstv4l2allocator.c:559:gst_v4l2_allocator_create_buf:<Video_0x7f9c98474780:pool0:src:allocator> error creating a new buffer: No buffer space available
0:00:17.919521415    53 0x7f9d08008120 ERROR         v4l2bufferpool gstv4l2bufferpool.c:479:gst_v4l2_buffer_pool_alloc_buffer:<Video_0x7f9c98474780:pool0:src> failed to allocate buffer
0:00:17.919534019    53 0x7f9d08008120 WARN              bufferpool gstbufferpool.c:305:do_alloc_buffer:<Video_0x7f9c98474780:pool0:src> alloc function failed

It's a local WPEWebKit Build on a 20.04 Ubuntu with Wayland.

Steps to reproduce:
1. Open a WebRTC-Session with for example BigBlueButton: https://test.bigbluebutton.org
2. Enable and disable the Camera, the camera hast to be released (not the case with jitsi)

Expected result:
The camera is disabled and the session is ongoing

Actual result:
The website hangs and the memory usage is increasing in small junks over time.
