--- Comment #2 from Anders Lund <and...@alweb.dk> ---
Hi,

Thanks a lot!

The LRV files plays in VLC and can be added to kdenlive projects and works 
there. According to kdenlive the set (.mp4 and .lrv) have the exact same 
length just as expected.

Sample files: https://alundnc.dynv6.net/index.php/s/soRPQpfnsz4e8zp


Below is a sample output from MediaInfo from the .LRV file:

I believe the 3 other streams are telemetry data, GPS and movement sensor. 
Those are available in the mp4 file as well, and if the qml mlt source ever 
becomes available those would be a fun use for that (like gauges and maps)
