can not take shot on iphone device when playing video ,on simulator wos ok! about react-native-view-shot HOT 9 CLOSED

can you precise what happens? Does it crash / does it renders black?

from react-native-view-shot.

not crash, called Promise catch and return error "Failed to capture view snapshot"

from react-native-view-shot.

I'll try to improve the error message because it's probably breaking internally in the Android side (it's Android, right?)

no it`s on ios real device,using react native video module to play hls Stream,

Ok. I'll give a try! it might be that the drawViewHierarchyInRect function returns FALSE and I'll need to see what's the way to fix it / get a better error message.

thanks

I think the error needs to be more clear or it should just renders something black (not this weird error).
but note that it's likely snapshotting a video won't work (maybe we'll have good surprise, but not sure!). see actually TheWidlarzGroup/react-native-video#95

I'm afraid currently answer is you can't.
even thought it seems to work on Simulator, the renderInContext does not work for Video, it renders black (if ignoring the returned value of drawViewHierarchyInRect – I don't want to ignore it and prefer the call to be a failure promise so you can deal with it and not end up with a black image)

– at least it's not possible with the video from react-native-video, therefore, it will be up to this library to provide you a way to get a snapshot from a video. and it's possible to do, but it needs lower level API calls ( http://stackoverflow.com/questions/8291727/ios-extracting-video-frames-as-images )

from react-native-view-shot.

we could find a generic solution that react-native-view-shot would use, like react-native-video could expose some sort of generic method we would duck-call. but i'll leave that to the following issue: TheWidlarzGroup/react-native-video#95
