[iOS] play local file from Documents directory

The player item is initialized to be able to play remote file or local file from the bundle. Init the URL using the [NSURL fileURLWithPath:uri]; can play local files not only from the bundle instead from the Documents folder. Really useful when the app created and saved the video itself (e.g. using the camera), and can specify an absolute path to the file locally. At this case the [[NSBundle mainBundle] pathForResource:uri ofType:type] will result nil.

I made this fix, here is the code to play all three type of asset:

• asset from the network
• asset from the app bundle
• asset from locally stored by the app (e.g in the Documents folder).

Replace these lines (242-244) from RTCVideo.m:

NSURL *url = (isNetwork || isAsset) ?
[NSURL URLWithString:uri] :
[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:uri ofType:type]];

to:

NSURL *url = nil;
if (isNetwork) {
    //Load based on the URL
    url = [NSURL URLWithString:uri];
}
else if (isAsset) {
    //Local asset: Can be in the bundle or the uri can be an absolute path of a stored video in the application

    //Check whether the file loaded from the Bundle,
    NSString *localPath = [[NSBundle mainBundle] pathForResource:uri ofType:type];
    if (localPath) {
        //Let's replace the `uri` to the full path'
        uri = localPath;
    }
    url = [NSURL fileURLWithPath:uri];
}

What link format for video in Documents must be after changing this code? file:///Users/user/Library/Developer/CoreSimulator/Devices/75TD86BA9-0H5E-7D9F-ND5G-349B2564093R/data/Containers/Data/Application/832F2C85-0F81-81E4-BB99-11E1B8A83053/Documents/videos/fcb5bf32a5cb108f278f2b911e728363.mp4 Like this?

Not working. URL started with uri://…, file://…, or simply /… not working after this changes in RTCVideo.m
