Hey!

Found what looks to be a bug/intentional bug.

Platform: Android Phones, Oculus Go, GearVR

Issue: When using Stream Media Source in a Media Player, the open command triggers a freeze for a few seconds. Tested with multiple formats and multiple project. Is consistent. Initial format this was found with is mp4 h264 aac.

Log from top down example - with a level begin play function:

[2019.02.15-18.16.52:196][278]LogBlueprintUserMessages: [TopDownExampleMap_C_7] ANDROID MOVIE STARTING //Traces when the open command happened
[2019.02.15-18.16.53:123][278]LogSlate: Took 0.000402 seconds to synchronously load lazily loaded font ‘…/…/…/Engine/Content/EngineFonts/Faces/RobotoRegular.ufont’ (155K)
[2019.02.15-18.17.10:586][326]LogAndroid: Case APP_CMD_PAUSE // Seems to be the culprit
[2019.02.15-18.17.10:595][326]LogAndroidEvents: Display: DequeueAppEvent : 6, 0
[2019.02.15-18.17.11:543][326]LogTcpMessaging: Lost node ‘E0382EE84C7B77AAF83864AAD07D5C0E’ on connection ‘127.0.0.1:36633’…
[2019.02.15-18.17.11:545][326]LogTemp: Android pause audio

Basically causes any stream media file loading on android to freeze frame for about 2-3 seconds.
Assuming its because of App_CMD_Pause, but why is that there in the first place?

Hi Jeff, the bug was reported before this post. I assumed this was a prerequisite to that.
The issue still does exist though. I do believe that this is an engine bug. Something which can easily go unnoticed for a good while.

Hi Hereafter,

did you find a solution? We have exactly the same problem.

I also couldn’t find the case you mentioned (Case # 00098964) Did you use the new bug reporting method to submit that bug?

And no, i wasnt able to fix it. It seems to affect only a few android devices including the Galaxy S devices (which are essentially a precursor to the Oculus Headsets). My advice, switch it up to download the video first and then play it. You’ll need some sort of loader/progress bar depending on what you are streaming. For Video players, i put a simple progress bar and make the video controls show when downloaded.
