First of all, I've checked stackoverflow again an again about this problem and I'm still not able to find out what's wrong ... I try to record a video, without audio, and I still have this prepared failed -1 issue ... The file is created but stays at 0kb. I tried different output format, check my manifest etc ... Can't find the problem :(
More info => I test my app on a Galaxy S2 android 2.3.5 ...
Any help more than appreciated ...
Thanks !
