Temporal patch to disable change resolution in OMX hardware encoder was not being applied
the definition MOZ_WEBRTC_OMX must be defined in video_engine_core.gypi to apply the patch in https://bugzilla.mozilla.org/show_bug.cgi?id=1067437.

Comment on attachment 8495899 [details] [diff] [review] define_disable_change_resolution.patch adds the define in the needed file to define MOZ_WEBRTC_OMX I spoke with jesup on irc to get some context for this request. This bug simply sets a build flag to disable resolution switching in a scenario where it will not be functional. This change has already been tested. Aurora+ and b2g32+
Please provide detailed information (Steps or description) if you need QA to verify this patch. Thanks.
Please verify it on b2g v2.0 and b2g v2.1 thanks
Hi, Oscar, Could you please provide the reproduce steps and user impact regarding this bug if you need QA to verify it? Thanks.
We are using phones, the best way to reproduce it is to move very fast one of the phones, for example from upside to downside continuously. This makes that the image content changes very fast. If you can see video after moving it, then everything is ok. If video 'breaks' (you see a black or green screen and then no video at all) then the test fails. Thanks
This bug and https://bugzilla.mozilla.org/show_bug.cgi?id=1067437 should be tested together with two phones, since it is a bit more difficult to get fast image changes in a desktop. In fact both bugs are about the same problem, disabling resolution change, but the current bug 1073486 is just a small fix because changes were not being correctly applied. Thanks!
Thanks Oscar! Have a nice day. :) Add "QAwanted"
I spent some time on an affected branch (2.1) the day before this issue was reported (in order to have a base for comparison on the latest builds) but I could not reproduce it with the steps on comment 13 after 5 minutes of flipping the phone upside down and back while watching videos. Oscar: Is there something wrong with what I was doing? I cannot verify this issue until I can reproduce it.
Forgot to give the environmental variables used. Environmental Variables: Device: Flame 2.1 BuildID: 20140925071142 Gaia: 86905e14c3ff06a0e6952ba635b6066ad2eea6b4 Gecko: a2e44f9dd87c Version: 34.0a2 (2.1) Firmware Version: L1TC10011800 User Agent: Mozilla/5.0 (Mobile; rv:34.0) Gecko/34.0 Firefox/34.0
I don't know if you are using flame v184 with new QC firmware. If that's the case you won't see the issue because it is already fixed by firmware. When I saw the bug, I was using 2.2 and I never tried 2.1, but that shouldn't be a problem, because on 2.1 the "define" was not set either. I think that you are testing it correctly, the trick is to have fast changes in image so the ratecontrol decides to downgrade the resolution to adjust itself to the fixed bitrate.
OK I had been on v180 and could not reproduce so hopefully someone else can try and get this verified for you.
