User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20151227030239 Steps to reproduce: Screencap-gonk is missig in multiple devices. For example, the Flame device has screencap and screenshot, but it doesn't include the screencap-gonk. Because of that, when screencap is executed, nothing happens: http://imgur.com/v95KJON.png This was expected (it's the proof that it used to work in older builds): http://imgur.com/MXJdQzh.png As a consequence, no screencast application works. There were some screencast apps for Android that worked also for Firefox OS, such as DroidAtScreen: http://droid-at-screen.org/ Tech Speakers and Reps need these kind of applications to work in order to show live demos and to record examples. If there is any workaround or if this can be proposed as a new feature for WebIDE, please let me know. Please, don't tag this as WONTFIX or a kitten will die. I swear it.
it works for me, sir. i have a Peak with actual master branch (23 Dic 2015) and i must to say screencap works flawlessly
This bug can be repro on the latest Flame 2.5&master, but can't be repro on latest Aires KK 2.5&master by the STR in Comment 0. Actual results: When executing the command "screencap" on Windows or Linux computer, it has no any response on Flame v2.5&master, but it shows some messy codes on Aries KK v2.5&master.

I think that it is not the same bug, :nhirata. That bug was related to the way that you have to take the screenshots. Probably, because of that bug, you started to use screencap-gecko. But for this new builds, screencap-gecko does not exist and "screencap" is a symbolic link pointing to nowhere (and that's why it doesn't generate any result). In my opinion, they are related but they are different bugs.

What I was trying to get at was I believe that it has to pass through the gecko layer so you wouldn't be able to use command line. Maybe I'm wrong. mwu or sotaro could probably let us know for sure. I should have deferred to their expertise.

I take a look about what is happening.

If we want to get correct screenshot(screencap), we need to take it via gecko since gonk uses hwc for final compositing. But we do not implement it yet. Bug 1144103 just adds support of screenrecord. screencap is implemented by the following. http://androidxref.com/6.0.0_r1/xref/frameworks/base/cmds/screencap/screencap.cpp#109 At first, it try to get screenshot by using ScreenshotClient. It try to get screenshot from ISurfaceComposer. If it failed, it falls back to /dev/graphics/fb0 readback. Since JB, /dev/graphics/fb0 might not be possible to readback. And even when if succeeds to read back, it might not be correct screenshot, since hwc is final compositing stage. On aries, /dev/graphics/fb0 could be read back. But on flame-kk, it could not be read back. It failed to map /dev/graphics/fb0. And on both devices, taking screenshot via ScreenshotClient was failed.

From comment 13, this bug is actually dup of Bug 1144103. We need to add support of ScreenshotClient, if we want to support "adb shell screencap" correctly.
