GoPro Hero 4 #1

Open brianmaxon opened 9 years ago

brianmaxon commented 9 years ago

Do you have any suggestions for modifying the code to support the GoPro Hero 4 (Silver) file format? I've included an excerpt from the header of a working file.

Adding the header pattern to AMRT.java allows the program to detect the presence of the video files, but the format of the header appears to be different so it fails to pass the checks in the VideoDecoder.readHeader method.

in AMRT.java

        g__headers[1]=new MediaDescriptor(MediaTypeEnum.Video,  MediaCodecEnum.MP4_mp41,        "\\x00\\x00\\x00\\x14\\x66\\x74\\x79\\x70\\x6D\\x70\\x34\\x31\\x20\\x13\\x10\\x18");

Hi, If you send me the log file (with your modified version), I might be able to give you some more information. Regards, Pierre

Yes it is !

Obviously, the header format is not the same than the one on GoPro Hero3 cameras... Can you send me (through a FTP or any cloud website) the data between 0x494e8000 and 0x4B7F0000 (around 36MB) so I can investigate and figure out what is the header structure ?

Thanks for your help!

Here is the link to the file with the data from between those hex addresses:

Any news on this?

I'm trying to recover my GoPro4 videos, but it looks like they're corrupted when trying with some other software...

Looking around I've found this about the Hero 4 format:

The Hero 4 range is similar to the Hero 3 above except the order of the atoms is different. On the Hero 4 the ftyp is immediately followed by the mdat. At the end of the recording, the moov atom is added. As in Hero 3 high and low resolution streams are interleaved give the same recovery issues.

I am also trying to use your software to reconstitute videos from a recovered Gopro4 silver. Please let me know if you have ideas for including this model. Many thanks
