Why delay setting the src until the onload?  Could work just as well in a <script> tag after the <video> element.

That would also work, would it make it a better test?

[Andrew Scherkus]

I remembered Eric Carlson suggested to use an onload handler instead of additional <script> blocks in https://bugs.webkit.org/show_bug.cgi?id=28327#c52

But if that was for a different reason than this, then I digress :)

Converting this movie to ogg format doesn't sense unless ogg files can contain a scaling matrix. If they can't it would make more sense to change video-no-audio.html to use a different video-only movie.

However, we can't land this patch because

new file mode 100644
index 0000000..1684a7b

we don't have scaled-matrix.ogv!  Please either upload a diff with the binary content or attach the file separately to this bug.

[Andrew Scherkus]

Doh forgive my noobness -- I'll fix up the patch one more time and get someone who sits by me to land the patch.

Ping?

[Andrew Scherkus]

I can upload a new version of the patch, but I can't create the baselines because I don't have Snow Leopard (QuickTime generates a completely different UI).

[Eric Seidel (no email)]

Oh.  OK.  The commit-queue is still running on Leopard, so only the leopard tests have to pass for it to actually commit.  But yes, you would need to look at the bots post-commit and post a patch with snow leopard results as well.  Sadly webkit doesn't have try-bots or a rebaselining tool to solve this for you yet.

[Andrew Scherkus]

Yikes.. ok I'll try and figure something out.

Thanks for the pointers!

[Eric Carlson]

I check in changes like this during a quiet time of the day and update the other port build results from the failed build-bot results.

It is a bit of a pain, but we don't have anything better just yet.

[Andrew Scherkus]

That might work.. but it's not a long-term solution.  I might be better off learning The Right Way to rebaseline media layout tests.

In the meantime I need to re-upload the patches.. they've gone a bit stale :)

[Eric Seidel (no email)]

There is plenty of historical precident for webkit committers using the build bots as try-bots, at least in terms of "check in and then get the new results off the bots" behavior.  Whether that is good or not is a topic for another discussion.  Regardless, existing committers do that all the time.  It's more difficult for you however, because if you manage to break a bot which the commit-queue blocks on:
http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/modules/buildbot.py#L47
then it won't be able to commit any follow-up patches for you as it will be waiting for the bots to roll green.  The commit-queue is only useful for committing patches which are not expected to break any bots.  It's useless for committing tree fixes, or patches which are expected to break things. :(

Changing Maciej's r+ to an r-.  This bug is lacking the binary data for the changed png files, so the commit-queue cannot land it.  Andrew is not yet a committer (according to committers.py), so someone would have to land this for him.  Better would be for Andrew to attach a patch containing the png changes.  "bugzilla-tool post-diff" or "bugzilla-tool post-commits" will handle git patches correctly.  Likewise one could just do a git diff --binary and attach that.

  This isn't new to your patch, but you should change this so it doesn't depend on a 'load' event being fired by the <audio> element.

You should check these in for SnowLeopard as well.

Eric's comment is correct. While all ports support wav at the moment, the spec doesn't require it so you should change this to use findMediaFile().

Do you need to set the svn:mime-type on these files somehow?

platform/mac-snowleopard/media doesn't exist... where you referring to platform/mac/media?

I'm confused... isn't that what my patch is doing in LayoutTests/media/audio-play-event.html ?

Using git I can't set the mime-type.. would have to be a follow-up patch or the committer could set it.

  Yes, SnowLeopard is the current mac platform.

  Yes, but I copied the wrong line from the diff. The problem is in audio-play-event.html where you are calling "run()" with the name of a platform specific media file. "run()" logs the name of the file passed to it so the test result has the platform specific name.

[Andrew Scherkus]

OK so I fixed the RUN(...) stuff in audio-play-event.html so it's platform independent and copied* the image results from mac-leopard to mac

* I'm positive it won't pass on mac (i.e., Snow Leopard) because Snow Leopard displays a fullscreen button in the controls.. not sure what to do here other than land the patch and grab the correct results off a bot?

Guidance appreciated!

[Andrew Scherkus]

I'm looking at http://build.webkit.org/builders/Tiger%20Intel%20Release and not seeing any media layout tests failing.

I'm still mastering the ropes here so by all means point out where/what I'm screwing up :)

[Eric Seidel (no email)]

My sincerest apologies.

I just finished writing a tool to help me look back in time to find failure like these.  Due to some problem builds on tiger, I started my crawl at r56619, which is in between when it broke and when you fixed it.  So my message to you was in error!

Again, sorry for the confusion.

[Andrew Scherkus]

No worries!
