fix for GoPro HERO9 #118

Closed genarks closed 2 years ago

genarks commented 2 years ago

Thank you for providing such a great software.

I would like to use the MP4 file output by the GoPro HERO9 as a source of gyro data, but it did not work.

The MP4 files output by the newer GoPros seem to have a different atom hierarchy. gpmd is no longer a child element of gmhd.

             Atom minf @ 329465 of size: 3292, ends @ 332757
                 Atom gmhd @ 329473 of size: 32, ends @ 329505

                     Atom stsd @ 329549 of size: 32, ends @ 329581
                         Atom gpmd @ 329565 of size: 16, ends @ 329581

I changed the gmhd to just make sure it exists directly under the minf.

I was able to get gyroflow working on my GoPro HERO9.

All outputs.

Maybe it has something to do with issue #88.
