Summary: Flash plays intermittently if border to window is 0px
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: Critical
Priority: P2
Component: WebKit Gtk
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: barry.scott at onelan.co.uk
The program webkit_flash show a problem that
flash will not always play if it fills the
window.
Adding a 1px border around the flash means
it always plays. But is not an acceptable
work around for our application.
The problem is intermittent, you will need
to run the test many times to trigger the
failure. (In our production application we
have 100% failure rate).
Environment.
The software is built and run on Fedora 13.
It breaks on a range of hardware from ATOM to
Dual Core 2 CPU.
Building using the provided Makefile.
make all
Running a test.
You can use the onelan.swf file to test flash.
Behaviour is different on file: and http:.
You will need to host the onelan.swf on a web server
to test from http:.
./webkit_flash --noborder <URL>
./webkit_flash --noborder file://./onelan.swf
You will need to run the program a lot to trigger the
failure. For example failing 1 in 10 or 20 runs.
When it does fail you will either see a grey rectangle
and no flash animation. Or you will see the animation
freeze.
Code notes.
The webkit_flash.cpp code is extracted from a larger
C++ application. We also have to run with the
code that is turned on by defining ONELAN_GDK_MUTEX_HACK
as we see GDK deadlock itself when playing flash.
