[FFmpeg-user] Extra streams in gopro videos - how do I examine?

[Jesper Taxbøl]

Hi Guys,

I am curious to find out what the two extra streams in my GoPro Hero4 video
are. How can I examine them and possibly dump their contents in a textfile?

They are called "GoPro TCD" and "GoPro SOS".

The sample video can be found below alongside the ffmpeg index.

Kind reagards
