I had this issue only on my iOS Simulator. Try using a physical device.

[FlatCodeIq]

Any solution please? I have the same issue on Physical Iphone and Simulator. the Video is progressing, but it only shows black screen and the loading indicator on top of the video.

On Android it works normally.

EDIT: I was using the latest version of better_player 0.0.81 but i changed to better_player 0.0.80 and now everything works. The problem was with the latest .81 version. Roll back to .80 until it's fixed.

Any solution to this problem, I am facing this issue on both real devices and simulator, my app is crashing with error NSInvalidArgumentException error, Error message says:-

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull _fastCStringContents:]: unrecognized selector sent to instance 0x1118c8fb0'

Downgrading to 0.0.80 is also not working. If am not playing any video then my app is working without any issues. Here is error log:

Hello, I did a fork of v0.0.83 and did a rollback of a feature that caused black screen on iOS simulator, in order to fix issue #1029, and probably will work for this too.

Please, I will be glad if you can, follow the instructions in this comment and help me to verify if this solves your black screen.

NOTE: The fork is not a fix and is only intended for issue verification purpose. The idea is to use the fork to check if you can see your videos with it (no black screen), this can give us hints about the problem. The fix can cause segmentation faults so do not use in production.
