Not supporting motion photos anymore on Android 12 #23

Closed gXxshock closed 2 years ago

I've tried the latest Windows build v3.3 and it does not extract videos anymore. I've tested it with motion photos from Android 12 on Pixel 4a. Older Android 11 photos still work. Seems like Google has changed the file structure.

Add the following line to the config (near the existing line with "Mp4Header_mp42_isommp42") <add key="Mp4Header_mp42_isommp41" value="00 00 00 1C 66 74 79 70 69 73 6F 6D" />

Found the crucial hint to ftypisom at https://mjanja.ch/2021/10/stripping-embedded-mp4s-out-of-android-12-motion-photos/ took the signature 66 74 ... from https://en.wikipedia.org/wiki/List_of_file_signatures and looked at the file in hex for 1C instead of 18. The length of the extracted video matches the EXIF tag "Directory Item Length" in bytes and the video looks fine.
