Nokia 6.1 phone #490

Closed gmmapowell closed 4 years ago

gmmapowell commented 4 years ago

I have a Nokia 6.1 phone and it generates MP4 videos which QuickTime recognizes but the metadata-extractor does not.

Looking into this, it seems that the identifying 8 bytes are ftypnvr1 which is not one of the options in QuickTimeTypeChecker.

Can you provide a sample file please? Ideally a very short one. For example, cover the lens with your hand and record a subsecond file, then upload it here. Be aware there may be GPS data in there.

Alternatively make and test the change yourself. It should be a very simple addition to this file:

Sure. Hope this is short enough. ftypnvr1.zip

@gmmapowell thanks for the sample file.
