Try this:

Hi Mark and Paul,
Sorry for the delay.
Thanks very much for the "shuffleframes" filter tip, this seems the right
tool to use, even if it implies reencoding.
My tests confirmed it works perfectly when the video starts with a mangled
5-frames group:
Input: B A E C D - B' A' E' C' D' - B" A" E" C" D" => jaggy
shuffleframes = 1 0 3 4 2
Output: A B C D E - A' B' C' D' E' - A" B" C" D" E" => smooth
Yay :-)
In actual files from the GoPro however...
Have you tried appealing to the manufacturer for a repair?
Based on a recent tip, try this command:
ffprobe -flags2 +showall -i ...
You may find that what you think is the first frame is not always the first
frame.
Good Luck--Mark.
