[FFmpeg-user] h264 not decoding

[Rens Dijkshoorn]

Hi Bouke,

I will ask the content owner, the smallest one i have is
1.5 Gb

Regards Rens

hmm, 
Action / sports / helmet cam? 
Do share the model / make, as i want to buy one myself :-) 
Does a straight import in Avid work? 

And just for fun, can i have a look at one of the files?
