I use "Screen Recording Mode"
recording target - Bandicam gives names :
bandicam 2015-12-04 12-41-05-580
bandicam 2015-12-04 14-03-01-667
bandicam 2015-12-07 16-47-43-749 etc.
always between 20 and 21 (22) min. disappears any audio : Windows,You Tube or Win. player...
no sound nowhere after 20 min: media player,Camtasia,Virtual Dub etc.
I think the problem AAC but why after 20 min ?
change FPS,quality,bitrate...I'm tired - lost a lot of time on testing :
22-25 min + testing...(+ how many deleted ?) - I'd like to help
The point of the story : This marked has audio and after 20 min ???
change FPS (23.976) and AAC bitrate (192) look MediaInfo :http://pastebin.com/A8BvMGhk
with the same setting all others do not have (after 20 min.)???
and maybe this my Win 10 Pro Version 1511 (OS build 10586.17) x64 - the real problem...do not be surprised...
Download and see - here disappears audio to 20 min 20 sec.http://1drv.ms/1HRlzfo
you see,this video problem - will not play OneDrive
I have no idea,all the best...
