We didn't get "canplaythrough", which for a stream means we didn't get to readyState HAVE_CURRENT_DATA.
This is most likely (I'd say 90%) because there was never a video frame in the stream.
Looks like the window sharing code is from GIPS, so, uhm, time to pull down their latest code? webrtc_trace logs might reveal something as well. Over to you Randell.

jimm, dmajor: if one of you has a win10 machine, can you try https://mozilla.github.io/webrtc-landing/gum_test.html and try window, screen and app sharing? If it doesn't work, can you re-run with NSPR_LOG_MODULES=mediamanager:4,webrtc_trace:65535,timestamp NSPR_LOG_FILE=somefile WEBRTC_TRACE_FILE=someotherfile (or WEBRTC_TRACE_FILE=nspr, which puts in the NSPR logs, but can kill perf - likely ok here).
If those all work, can you try a local run of the mochitest file (and modify the NSPR_LOG_MODULES in build/automation.py.in to set those, and add the trace file var)?
Thanks!

I haven't had a chance to log anything but it isn't working for me in win10 release. The list of windows or screens to share is disabled with no entries. So confirming.

Sorry, false report. The drop down looked disabled (grayed out) but I could have clicked it. It had the nightly window listed. Selecting that, I am able to share it in the test page.

If the dims you pass request a 0x0 bitmap, you get this kind of result.

Jim, Mreavy,
So taking inspiration from a pastebin on IRC here is the current patchset pushed to try:
https://treeherder.mozilla.org/#/jobs?repo=try&revision=d5b28569c07b
This is based on a green m-c rev:
https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=205427533c56&filter-searchStr=Windows
This should be finished "soon" (not long after the build itself finish) and we'll see results.
n-i'ing you to be sure theres a followup once done

(desktop_frame_win.cc:53): Failed to allocate new window frame 0 height=4 width=-8 bitcount=32 biSize=40 biSizeImage=128
0 is GetLastError()
Note that biHeight = -size.height(), so size.height() == -4(!) and size.width = -8(!) (and biSizeImage = size.width()*bytesperpixel*size.height() = 128). biSizeImage makes (kinda) sense in that it's negative*negative...
in media/webrtc/trunk/webrtc/modules/desktop_capture/win/window_capture_utils.cc, if window_placement.showCmd & SW_SHOWMAXIMIZED is true, it adjusts the width and height to remove Border width/height; perhaps those values are "unexpected" in this case?

Just confirming, this code run in the browser process correct?
Looking at the utils routine, it returns false when apis fail. Maybe some callers fail to check this?

Or maybe instead of a failure here (since the follow up call to GetLastError returns 0) maybe the window you pass in is 0x0? Then you subtract the system non-client area border and Voilà, negative width/height.

A 0x0 window was what I suspect (once I saw the negatives, and why I mentioned the border subtraction).
The tests IIRC select a random window (first one in the list); I suspect some sort of fake non-visible window is first on the test machine. We can verify this, and in the longer run improve the test to select a specific window somehow (would require test-only interfaces I think), or have it block from offering windows with negative sizes (which would require a bunch of geometry-check calls when building the list - but that's not a huge problem as we're planning to offer thumbnails). Or select the *last* window!
If we can confirm this, we may want to disable the test on win10 until we resolve it. (if selecting last window doesn't work)
(chatted with mreavy, we're in sync)

That's really awful. :( I'm amazed it actually works on other platforms. You might consider disabling the test on all platforms until this gets fixed.

Well, it *should* be able to share any window in the list it provides, so it should work. That said, a specific window would be *better*, but: this is really painful to do in a mochitest, since we explicitly don't give applications any info or way to select which window is captured; that's totally up to the user. Of course, in this case there is no use, which means we'd have to make a side-interface to force it to share a specific window (and we'd have to create said window as well).
Giving the user an option to share a window that isn't actually shareable is a bug (albeit a relatively minor one). It just happens to be biting us here.

Perhaps we should block negative sizes as a belt-and-suspenders (limit to 0); negative sizes don't make sense anyways.
Should be a simple patch. Looking for someone to take it and push a try to verify if it works.

Nico - would you feel comfortable taking this as a first bug? Randell has agreed to mentor getting you through the process of landing this. We're really just looking at blocking negative sizes for sanity. Thanks!

Additionally, it looks like on Windows 10 the Store application is launched at startup and suspended until the user actually launches it. The Store window is available in the drop down list, and sharing it results in sharing a black screen, but no errors. Once the Store has been launched by the user and closed it will not appear in the list until it is opened again.
