Hi everyone,
I found what was the problem. My phone Galaxy S7 was not enough powerful to play the feedback video (even whthout HD feedback enabled).
For the files in the internal memory of the
mavic 2 pro, my computer wasn't enough powerful to play the videos files UNLESS I use "Movies and TV" application because it is the ONLY ONE using efficiently GPU power.
VLC, Media Player Classic or Windows Media Player were mostly using my CPU power to play videos of the
Mavic 2 Pro and it wasn't enough.
Now
with "Movies and TV" my GTX960 is mostly used to play H265 videos so playback is perfect!
Hope It could help...
